Objectives This study aimed to assess the effectiveness of virtual reality (VR) in managing different types of pain in different age groups and to provide evidence for the clinical application of new alternative strategy for pain management. Methods Electronic databases, including the Cochrane Library, PubMed, EMBASE, and the Web of Science, were searched for studies published up to October 2020. Randomized controlled trials that reported on VR for pain management were included. Results A total of 31 randomized controlled trials were included. As for the pain intensity, the increase of visual analog scale score in the VR group was 1.62 scores less than that in the control group. In juvenile patients, the VR group had 1.79 scores lower than that in control group. For adult patients, the VR group had 1.34 scores lower than that in control group. As for other pain-related indicators, the VR group had lower levels of anxiety, lower pain unpleasantness, lower pulse rate, and shorter duration of dressing change and spent less time thinking about pain. Nevertheless, there was no statistical difference in pain tolerance. VR can effectively alleviate acute pain. In terms of chronic low back pain and cancer-related pain, there was no statistical difference between VR therapy and standard therapy. Conclusions VR is a feasible alternative therapy for both juveniles and adults in pain management, and it has a greater potential for juveniles. VR can effectively alleviate acute pain. Nevertheless, VR showed little effectiveness in increasing pain tolerance, which may explain in part the ineffectiveness of VR therapy in pain management for chronic pain.

IntroductionAmputations result from trauma, war, conflict, vascular diseases and cancer. Phantom limb pain (PLP) is a potentially debilitating form of chronic pain affecting around 100 million amputees across the world. Mirror therapy and virtual reality (VR) are two commonly used treatments, and we evaluated their respective success rates.MethodsA meta-analysis and systematic review was undertaken to investigate mirror therapy and VR in their ability to reduce pain levels. A mean difference (MD) model to compare group pain levels pretreatment and post-treatment via aggregating these results from numerous similar studies was employed. Meta-analysis was conducted using RevMan (V.5.4) and expressed in MD for visual analogue scale (VAS) score.ResultsA total of 15 studies met our search criteria; they consisted of eight mirror therapy with 214 participants and seven VR including 86 participants, totalling 300 participants. Mean age ranged from 36 to 63 years, 77% male, of which 61% were lower body amputees. Both led to a VAS reduction (mirror therapy mean reduction VAS score was 2.54, 95% CI 1.42 to 3.66; pConclusionsMirror therapy and VR are both equally efficacious in alleviating PLP, but neither is more effective than the other. However, due to small sample size and limited number of studies, factors such as gender, cause of amputation, site of limb loss or length of time from amputation, which may influence treatment success, could not be explored.

Virtual reality (VR) has been shown to produce analgesic effects during different experimental and clinical pain states. Despite this, the top-down mechanisms are still poorly understood. In this study, we examined the influence of both a real and sham (ie, the same images in 2D) immersive arctic VR environment on conditioned pain modulation (CPM) and in a human surrogate model of central sensitization in 38 healthy volunteers. CPM and acute heat pain thresholds were assessed before and during VR/sham exposure in the absence of any sensitization. In a follow-on study, we used the cutaneous high frequency stimulation model of central sensitization and measured changes in mechanical pain sensitivity in an area of heterotopic sensitization before and during VR/sham exposure. There was an increase in CPM efficiency during the VR condition compared to baseline (P < .01). In the sham condition, there was a decrease in CPM efficiency compared to baseline (P < .01) and the real VR condition (P < .001). Neither real nor sham VR had any effect on pain ratings reported during the conditioning period or on heat pain threshold. There was also an attenuation of mechanical pain sensitivity during the VR condition indicating a lower sensitivity compared to sham (P < .05). We conclude that exposure to an immersive VR environment has no effect over acute pain thresholds but can modulate dynamic CPM responses and mechanical hypersensitivity in healthy volunteers. PERSPECTIVE: This study has demonstrated that exposure to an immersive virtual reality environment can modulate perceptual correlates of endogenous pain modulation and secondary hyperalgesia in a human surrogate pain model. These results suggest that virtual reality could provide a novel mechanism-driven analgesic strategy in patients with altered central pain processing.

Objective To assess the efficacy of virtual reality (VR)-based vs conventional balance training on the improvement of balance and reduction of falls in people with multiple sclerosis (PwMS). Design Single-blinded, randomized, controlled trial. Setting Musculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences. Participants PwMS (N=39), randomized into VR (n=19) and control (n=20) groups. Intervention The VR group performed exergames using Kinect, while the control group accomplished conventional balance exercises. Both groups received 18 training sessions for 6 weeks. Main Outcome Measures Limits of stability, timed Up and Go (TUG) test, and 10-m walk tests with and without cognitive task and their dual-task costs (DTCs), Berg Balance Scale, Multiple Sclerosis Walking Scale-12, Fall Efficacy Scale-International, Activities-specific Balance Confidence Scale, and fall history were obtained pre- and post intervention and after a 3-month follow-up. Results At both post intervention and follow-up, TUGcognitive and DTCs on the TUG were significantly lower and the 10-m walkcognitive was significantly higher in the VR group. At follow-up, reaction time and the number of falls demonstrated significant differences favoring the VR group, whereas the directional control revealed significant difference in favor of the control group (P Conclusions Both the VR-based and conventional balance exercises improved balance and mobility in PwMS, while each acted better in improving certain aspects. VR-based training was more efficacious in enhancing cognitive-motor function and reducing falls, whereas conventional exercises led to better directional control. Further studies are needed to confirm the effectiveness of recruiting VR-based exercises in clinical settings.

The purpose of this study was to explore the use of immersive and interactive virtual reality (VR) for analgesia, anxiety reduction, and overall satisfaction in patients undergoing outpatient postoperative debridements.Randomized crossover-controlled trial.Academic outpatient clinic.Adult patients who had functional endoscopic sinus surgery and skull base surgery and were undergoing office-based postoperative nasal endoscopy and debridement were recruited and followed for 2 consecutive office visits. Participants were randomized to receive either the control or experimental analgesia for the first postoperative visit (PO1) and crossed over into the opposite treatment arm during the second postoperative visit (PO2). Outcomes included procedural pain, anxiety and satisfaction scores, procedural time, and reflexive head movements per minute (RHM).Eighty-two participants were recruited. At PO1, 39 received standard analgesia, and 43 received an immersive VR experience. At PO1, the VR group experienced significantly less anxiety (VR technology holds promise as a nonpharmacologic analgesic and anxiolytic intervention for otolaryngology office-based procedures. Further study of VR use in other procedures is warranted.1, randomized controlled trial.

Objective: Virtual reality (VR), a novel and highly immersive technology, offers promise in addressing potential psychological impacts of cancer treatments and hospitalization. The primary aim of this study was to examine multiple key user perspectives on the acceptability and feasibility of an Immersive VR therapeutic intervention for use with hospitalized patients with cancer. Secondary aims were to identify issues and opportunities related to the adoption and clinical implementation of VR in pediatric oncology settings. Method: The study was conducted at The Royal Children’s Hospital (RCH), Melbourne, Australia. Thirty multidisciplinary oncology health care professionals participated in an initial test of VR intervention usability (Stage 1). Ninety oncology inpatients (7-19 years) and their parent caregivers participated in a pilot randomized controlled study to examine the effectiveness of an Immersive VR therapeutic intervention (Stage 2). This mixed methods study reports Stages 1 and 2 quantitative and qualitative data related to VR feasibility and acceptability. Results: Results indicate favorable perceptions from health care professionals with respect to ease of use and usefulness of VR, and had positive intentions to use it in the future. Parent caregivers reported high acceptability of VR for their hospitalized child. Patients reported high satisfaction of the VR intervention within minimal adverse effects. Barriers and facilitators to VR use with seriously ill children and specific recommendations for content development were elicited. Conclusion: This study shows that there are several potential clinical uses for Immersive VR intervention, beyond medical procedural distraction, to support psychological adjustment to hospitalization and patient quality of life.

Background Fasciotomy is a life-saving procedure to treat acute compartment syndrome, a surgical emergency. As fasciotomy dramatically improves wound pain, it should be performed as soon as possible. Moreover, delays in the use of fasciotomy can increase the rate of wound infections. Once the fasciotomy wound is infected, pain control is achieved via the long-term use of opioids or anti-inflammatory analgesics. However, the administration of high doses of opioids may cause complications, such as respiratory depression, over-sedation, and constipation. Therefore, treatment methods other than narcotic administration should be established to better manage the pain caused by fasciotomy wound infections. Virtual reality has recently been introduced in analgesic therapy as a replacement, or complement, to conventional pharmacological treatments. Its use has been extensively studied in the pain management of patients with burns. An increasing number of painful conditions are being successfully treated with virtual reality. Here, we report a case of acute compartment syndrome complicated by fasciotomy wound infection. Case presentation A 40-year-old Japanese man suffering from acute compartment syndrome of his leg due to a car accident trauma was treated with a fasciotomy to decompress intra-compartmental pressure and restore tissue perfusion, and admitted to an intensive care unit. Unfortunately, as the open fasciotomy wound was complicated by infection, he complained of hyperalgesia and severe pain during wound debridement. He was therefore given acetaminophen and high-dose intravenous patient-controlled analgesic fentanyl (35 μg/kg per day) to reduce the pain. Despite these efforts, the pain was poorly controlled and opioid-induced side effects such as respiratory depression were observed. An immersive virtual reality analgesic therapy aimed at distraction and relaxation was used and effectively alleviated the pain. Three sessions of virtual reality analgesic therapy over 2 days produced sustainable analgesic effects, which led to a 25–75% dose reduction in fentanyl administration and the concomitant alleviation of respiratory depression. Conclusions This case suggests the feasibility of virtual reality analgesic therapy for pain management of fasciotomy wound complications in acute compartment syndromes. Virtual reality represents a treatment option that would reduce analgesic consumption and eliminate opioid-induced respiratory depression to treat fasciotomy wound infection.

Background Different non-pharmacological techniques, including hypnosis and virtual reality (VR) are currently used as complementary tools in the treatment of anxiety, acute and chronic pain. A new technique called virtual reality hypnosis (VRH), which encompasses a combination of both tools, is regularly used although its benefits and underlying mechanisms remain unknown to date. With the goal to improve our understanding of VRH combination effects, it is necessary to conduct randomised and controlled research trials in order to understand their clinical interest and potential benefits. Methods Patients (n = 100) undergoing cardiac surgery at the Liège University Hospital will be randomly assigned to one of four conditions (control, hypnosis, VR or VRH). Each patient will receive two sessions of one of the techniques: one the day before the surgery and one the day after. Physiological assessments will be made on the monitor and patients will rate their levels of anxiety, fatigue, pain, absorption and dissociation. Discussion This study will help to expand knowledge on the application of virtual reality, hypnosis and VRH in the specific context of cardiac and intensive care procedures, and the influence of these non-pharmacological techniques on patient’s anxiety, fatigue, pain and phenomenological experience. Trial registration ClinicalTrials.gov: NCT03820700. Date registered on 29 January 2019. Study recruitment date: October 6, 2018. Study anticipated completion date: December 28, 2020.

Balance and mobility deficits are most prevalent impairments in patients with traumatic brain injury (TBI). The evidence has proposed that rehabilitation plays an important role in improving balance and mobility post-TBI. Virtual reality (VR) is a computer technology that provides immersed users to generate feedback such as visual, audio, and haptic.This review aimed to examine the effects of the VR treatment intervention on balance and mobility in patients with TBI and to define the most effective VR treatment protocol.SCOPUS, PEDro, PubMed, REHABDATA, EMBASE, and the web of science were searched for experimental trials examining the impacts of VR training on balance and mobility in patients with TBI from inception until July 2022. Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the selected studies.Five randomized controlled trials (RCTs) met the inclusion criteria. The PEDro scores ranged from 6 to 8, with a median of 6. A total of 157 patients with TBI were included in this review, 31.2% of whom were females. The findings showed that VR intervention is not superior to traditional physiotherapy interventions in improving balance and mobility post- TBI.The preliminary findings showed that the influence of VR on the balance and mobility ability in patients with TBI is promising. Combining VR with other concurrent rehabilitation interventions may show more significant improvements in balance and mobility compared to VR interventions alone. The optimal VR treatment protocol remains unclear. Further randomized controlled trials are strongly needed.

Virtual reality-assisted cognitive-behavioural therapy (VR-CBT) has potential to support people who experience paranoid ideation in social settings. However, virtual reality (VR) research using overt social environments is limited, and lack of qualitative studies on paranoid ideation in VR restricts understanding. This study aimed to use predominantly qualitative methods to investigate subjective experience of paranoia in VR and identify target domains for VR-CBT. Participants (N = 36) were non-clinical adults with high trait paranoia, who entered an interactive VR bar-room environment. After VR, they participated in brief audiotaped semi-structured interviews designed for measuring persecutory ideation in virtual environments. Researchers scored transcripts on the Comprehensive Assessment of At-Risk Mental States Non-Bizarre Ideas Global Rating Scale to rate the state paranoia represented by interview content. Thematic analysis of interviews employed superordinate themes of Social Evaluative Concerns, Ideas of Reference, and Ideas of Persecution to investigate participants' experience of paranoia. Mean score on the Non-Bizarre Ideas scale was 3.06 (standard deviation 1.24, range 1-6), indicating "moderate" attenuated-paranoid experiences. Nearly all participants reported Social Evaluative Concerns (N = 35) and Ideas of Reference (N = 32); half reported Ideas of Persecution (N = 19). Twelve subthemes were identified. Notably, participants believed they did not belong in the environment (N = 31), that they were the object of discussion (N = 20), and that they felt avatars were unfriendly (N = 27) and intentionally rejected them (N = 13). Subthemes reflect interpersonal and social processes that may constitute target areas for VR-CBT, for example, cognitive appraisals and social skills. Identification of these domains indicates how personalized VR-CBT may be operationalized.

Background: Veterans with posttraumatic stress disorder (PTSD) tend to benefit less from evidence-based treatments than other PTSD populations. A novel virtual reality and motion-assisted exposure therapy, called 3MDR, provides treatment in an immersive, personalized and activating context. Objective: To study the efficacy of 3MDR for veterans with treatment-resistant PTSD. Method: In a randomized controlled trial (n = 43) 3MDR was compared to a non-specific treatment component control group. Primary outcome was clinician-rated PTSD symptoms at baseline, after 3MDR, and at the 12-week and 16-week follow-up (primary end point). Intention-to-treat analyses of covariance and mixed models were applied to study differences between groups at the end point and over the course of intervention, controlling for baseline scores. Results: The decrease in PTSD symptom severity from baseline to end point was significantly greater for 3MDR as compared to the control group, with a large effect size (F[1, 37] = 6.43, p = 0.016, d = 0.83). No significant between-group difference was detected in the course of PTSD symptoms during treatment when including all time points. The dropout rate was low (7%), and 45% of the patients in the 3MDR group improved clinically. The number needed to treat was 2.86. Conclusions: In this trial, 3MDR significantly decreased PTSD symptoms in veterans with, on average, a history of 4 unsuccessful treatments. The low dropout rate may be indicative of high engagement. However, a lack of significant differences on secondary outcomes limits conclusions that can be drawn on its efficacy and underlines the need for larger phase III trials. These data show emerging evidence for 3MDR and its potential to progress PTSD treatment for veterans (Dutch Trial Register Identifier: NL5126).

Augmented reality (AR) uses the real-world setting but enables a person to interact with virtual objects. In this study, we aimed to explore the use of alphabet letter and number in an AR task and its influence in reaction time in a population with autism spectrum disorders (ASD) compared with the performance of typical developing (TD) controls. We evaluated reaction time before and after AR tasks that consisted of identifying correct numbers and alphabet letters in 48 people with ASD and 48 with TD controls. Results indicate that total points for TD group were higher (

BACKGROUND Facial feminization surgery entails a series of surgical procedures that help the transwoman pass as their affirmed gender. Although virtual surgical planning, with intraoperative cutting guides, and custom plates have been shown to be helpful for craniomaxillofacial reconstruction, they have not yet been studied for facial feminization surgery. The authors used cadaveric analysis for morphologic typing and to demonstrate the utility of virtual surgical planning in facial feminization surgery procedures. METHODS Male cadaveric heads underwent morphologic typing analysis of the frontal brow, lateral brow, mandibular angle, and chin regions (n = 50). Subsequently, the cadavers were split into two groups: (1) virtual surgical planning intraoperative cutting guides and (2) no preoperative planning. Both groups underwent (1) anterior frontal sinus wall setback, (2) lateral supraorbital recontouring, (3) mandibular angle reduction, and (4) osseous genioplasty narrowing. Efficiency (measured as operative time), safety (determined by dural or nerve injury), and accuracy (scored with three-dimensional computed tomographic preoperative plan versus postoperative result) were compared between groups, with significance being p < 0.05. RESULTS For frontal brow and lateral lower face, morphologic type 3 (severe) predominated; for lateral brow and chin, type 2 (moderate) predominated. For frontal sinus wall setback, virtual surgical planning improved efficiency (19 minutes versus 44 minutes; p < 0.05), safety (100 percent versus 88 percent; p < 0.05; less intracranial entry), and accuracy (97 percent versus 79 percent; p < 0.05) compared with no preoperative planning. For mandibular angle reduction, virtual surgical planning improved safety (100 percent versus 88 percent; p < 0.05; less inferior alveolar nerve injury) and accuracy (95 percent versus 58 percent; p < 0.05). CONCLUSIONS Preoperative planning for facial feminization surgery is helpful to determine morphologic typing. Virtual surgical planning with the use of cutting guides/custom plates improved efficiency, safety, and accuracy when performing four key craniofacial techniques for facial feminization.

Immersive virtual reality (VR) is a technology that provides a more realistic environmental design and object tracking than ordinary VR. The aim of this study was to investigate the effectiveness of immersive VR on upper extremity function in patients with ischemic stroke. Sixty-five patients with ischemic stroke were included in this randomized, controlled, double-blind study. Patients were randomly divided into VR (n = 33) and control (n = 32) groups. The VR group received 60 minutes of the upper extremity immersive VR rehabilitation program and the control group received 45 minutes of conventional therapy and 15 minutes of a sham VR program. Rehabilitation consisted of 18 sessions of therapy, three days per week, for six weeks. The outcome measures were the Action Research Arm Test (ARAT), Functional Independence Measure (FIM), Fugl-Meyer Upper Extremity Scale (FMUE) and Performance Assessment of Self-Care Skills (PASS). In both the VR and control groups all parameters except the PASS improved over time. However independent t-test results showed that all of the FMUE, ARAT, FIM and PASS scores were significantly higher in the VR group compared with the control (p < 0.05). The minimal clinically important difference (MCID) scores of the FMUE and ARAT were higher than the cut-off MCID scores described in the literature in the VR group, whereas the FIM scores were below the cut-off MCID scores. All scores in the control group were below the cut-off scores. Immersive VR rehabilitation appeared to be effective in improving upper extremity function and self-care skills, but it did not improve functional independence. RESUMO A VR imersiva é uma tecnologia que fornece design ambiental e rastreamento de objetos mais realistas do que a VR comum. O objetivo deste estudo foi investigar a eficácia da VR imersiva na função da extremidade superior em pacientes com AVC isquêmico. Sessenta e cinco pacientes com AVC isquêmico foram incluídos neste estudo randomizado, controlado e duplo-cego (clinictrials.gov. ID: NCT03135418). Os pacientes foram divididos aleatoriamente em VR (n = 33) e controle (n = 32). O grupo VR recebeu 60 minutos do programa de reabilitação imersiva da extremidade superior e o grupo controle recebeu 45 minutos de terapia convencional e 15 minutos de um programa falso de VR. A reabilitação consistiu em 18 sessões de terapia, 3 dias por semana, durante 6 semanas. As medidas de resultado foram Teste de braço de pesquisa-ação (ARAT), Medida de independência funcional (FIM), Escala de extremidades superiores de Fugl-Meyer (FMUE) e Avaliação de desempenho de habilidades de autocuidado (PASS). Nos grupos VR e controle, todos os parâmetros, exceto o PASS, melhoraram com o tempo. No entanto, os resultados dos testes t independentes mostraram que todos os escores FMUE, ARAT, FIM e PASS foram significativamente maiores no grupo VR em comparação ao controle (p

Virtual reality exposure therapy (VRET) for PTSD is an emerging treatment of remarkable promise, but its efficacy and safety are still unclear. Our aim was to investigate the efficacy of VRET for individuals with PTSD, and to identify the potential moderating variables associated with interventions.Literature search was conducted via PubMed, Embase, Web of Science, Cochrane Library, PsycInfo, Science Direct, and EBSCO. We identified 18 studies on PTSD including 13 randomized controlled trials (RCTs; 654 participants) and 5 single-group trials (60 participants).The main effects analysis showed a moderate effect size (g = 0.327, 95% CI: 0.105-0.550, p0.01) for VRET compared to control conditions on PTSD symptoms. Subgroup analysis revealed that the effects of VRET were larger when compared to inactive groups (g = 0.567) than active control groups (g = 0.017). This finding was in agreement with depressive symptoms. A dose-response relationship existed with more VRET sessions showing larger effects. There was a long-range effect of VRET on PTSD symptoms indicating a sustained decrease in PTSD symptoms at 3-month follow-up (g = 0.697) and 6-month follow-up (g = 0.848). The single-group trials analysis revealed that the VRET intervention had a significant effect on PTSD.Many of the combat-related PTSD subjects resulted in uncertainty regarding meta-analytical estimates and subsequent conclusions.These findings demonstrated that VRET could produce significant PTSD symptoms reduction and supported its application in treating PTSD.

BackgroundThe promise of precision medicine for autism spectrum disorder (ASD) hinges on developing neuroscience-informed individualized interventions. Taking an important step in this direction, we investigated neuroplasticity in response to an ecologically-valid, computer-based social-cognitive training (SCOTT).MethodsIn an active control group design, 48 adults with ASD were randomly assigned to a 3-month SCOTT or non-social computer training. Participants completed behavioral tasks, a functional and structural magnetic resonance imaging session before and after the training period.ResultsThe SCOTT group showed social-cognitive improvements on close and distant generalization tasks. The improvements scaled with reductions in functional activity and increases in cortical thickness in prefrontal regions.ConclusionIn sum, we provide evidence for the sensitivity of neuroscientific methods to reflect training-induced social-cognitive improvements in adults with ASD. These results encourage the use of neuroimaging data to describe and quantify treatment-related changes more broadly.

Active duty military service members have high dropout rates for trauma-focused treatment in both clinical practice and research settings. Measuring patients' intent to complete (ITC) and intent to attend (ITA) treatment have been suggested as methods to reduce dropout, but no studies have examined the effectiveness of such measures. In an attempt to reduce high dropout rates, measures of ITC and ITA were included in a randomized controlled trial evaluating prolonged exposure (PE) and virtual reality exposure (VRE) in active duty soldiers with posttraumatic stress disorder (PTSD). Participants (N = 108) were randomized to either PE or VRE, and the last 49 to enroll were administered a measure of ITC at enrollment and a measure of ITA at the end of every session. A score of 7 or below triggered a problem-solving discussion with the individual's therapist. The results revealed that the ITA assessment predicted treatment dropout after controlling for mental health stigma, PTSD symptoms, and age, odds ratio (OR) = 0.24, p = .023. Additionally, participants who completed the ITA assessment were less likely to drop out than those who were not administered the ITA, OR = 0.29 p = .002. The ITC did not predict treatment dropout OR = 0.98, p = .402. These findings suggest that assessing ITA throughout trauma-focused therapy may reduce treatment dropout rather than solely measuring ITC prior to starting psychotherapy. Based on these preliminary findings, future research should randomize the measurement of ITA in clinical trials to evaluate its impact on treatment dropout.Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) La efectividad de la intención de completar y la intención de asistir a la intervención para predecir y prevenir el abandono del tratamiento para el TEPT del soldado INTENCIÓN DE ASISTIR A LA TERAPIA DE EXPOSICIÓN PARA EL TEPT Los miembros del servicio militar en servicio activo tienen altas tasas de abandono del tratamiento centrado en el trauma, tanto en la práctica clínica como en la investigación. La medición de la intención de los pacientes de completar el tratamiento (ITC en su sigla en inglés) y la intención de asistir (ITA en su sigla en inglés) se han sugerido como métodos para reducir el abandono, pero ningún estudio ha examinado la efectividad de tales medidas. En un intento por reducir las altas tasas de abandono, se incluyeron medidas de la ITC y la ITA en un ensayo controlado aleatorio que evaluaba la exposición prolongada (PE en su sigla en inglés) y la exposición de realidad virtual (VRE en su sigla en inglés) en soldados en servicio activo con trastorno de estrés postraumático (TEPT). Los participantes (N = 108) fueron asignados al azar a PE o VRE, y a los últimos 49 que se inscribieron se les administró una medida de ITC al momento de la inscripción y una medida de ITA al final de cada sesión. Un puntaje de 7 o menos desencadenó una discusión de resolución de problemas con el terapeuta del individuo. Los resultados revelaron que la evaluación ITA predijo el abandono del tratamiento después de controlar el estigma de salud mental, los síntomas del TEPT y la edad, razón de probabilidades (OR) = 0.24, p = .023. Además, los participantes que completaron la evaluación ITA tenían menos probabilidades de abandonar que aquellos que no recibieron la ITA, OR = 0.29, p = .002. El ITC no predijo el abandono del tratamiento OR = 0.98, p = .402. Estos hallazgos sugieren que evaluar la ITA a lo largo de la terapia centrada en el trauma puede reducir el abandono del tratamiento en lugar de solo medir el ITC antes de comenzar la psicoterapia. En base a estos hallazgos preliminares, la investigación futura debe aleatorizar la medición de ITA en ensayos clínicos para evaluar su impacto en el abandono del tratamiento.Traditional and Simplified Chinese Abstracts by the Asian Society for Traumatic Stress Studies (AsianSTSS) 簡體及繁體中文撮要由亞洲創傷心理研究學會翻譯 Effectiveness of the Intent to Complete and Intent to Attend Intervention to Predict and Prevent Soldier PTSD Treatment Drop Out Traditional Chinese 標題: 完成治療和參與治療的意圖測量, 對於預測和防止軍人退出PTSD治療的功效 撮要: 在臨床實踐和研究個案中, 現役軍人在聚焦創傷治療都有高的退出率。過去曾有人提出, 測量患者完成治療的意圖(ITC)和參與治療的意圖(ITA), 可減低治療退出率。可是, 目前仍沒有研究檢視這類測量的功效。為改善目前現役軍人的高治療退出率, 本隨機對照試驗檢視患創傷後壓力症(PTSD)的現役軍人, 評估樣本的延長暴露(PE)和虛擬現實暴露(VRE), 測量ITC和ITA。樣本(N = 108)受隨機派至PE或VRE組, 最後49名加入的樣本則在加入時接受ITC測量, 及在完成每個節段時接受ITA測量。樣本的分數為7分或以下時, 便要與治療師討論如何解決問題。結果反映, 在我們對心理疾病的污名、PTSD症狀、年齡進行對照後, ITA評估預測了治療退出率 (勝算比 (OR) = 0.24, p = .023) 。此外, 有進行ITA評估的樣本相比並無進行ITA的樣本, 其退出治療的機會較小(OR = 0.29 p = .002)。ITC並未能預測治療退出率(OR = 0.98, p = .402)。研究結果反映, 在聚焦創傷治療期間評估ITA, 而非在心理治療開始前評估ITC, 可能可以減低治療退出率。未來研究應基於這些初步發現, 在臨床的隨機試驗測量ITA, 以檢視其對治療退出率的效應。 Simplified Chinese 标题: 完成治疗和参与治疗的意图测量, 对于预测和防止军人退出PTSD治疗的功效 撮要: 在临床实践和研究个案中, 现役军人在聚焦创伤治疗都有高的退出率。过去曾有人提出, 测量患者完成治疗的意图(ITC)和参与治疗的意图(ITA), 可减低治疗退出率。可是, 目前仍没有研究检视这类测量的功效。为改善目前现役军人的高治疗退出率, 本随机对照试验检视患创伤后压力症(PTSD)的现役军人, 评估样本的延长暴露(PE)和虚拟现实暴露(VRE), 测量ITC和ITA。样本(N = 108)受随机派至PE或VRE组, 最后49名加入的样本则在加入时接受ITC测量, 及在完成每个节段时接受ITA测量。样本的分数为7分或以下时, 便要与治疗师讨论如何解决问题。结果反映, 在我们对心理疾病的污名、PTSD症状、年龄进行对照后, ITA评估预测了治疗退出率 (胜算比 (OR) = 0.24, p = .023) 。此外, 有进行ITA评估的样本相比并无进行ITA的样本, 其退出治疗的机会较小(OR = 0.29 p = .002)。ITC并未能预测治疗退出率(OR = 0.98, p = .402)。研究结果反映, 在聚焦创伤治疗期间评估ITA, 而非在心理治疗开始前评估ITC, 可能可以减低治疗退出率。未来研究应基于这些初步发现, 在临床的随机试验测量ITA, 以检视其对治疗退出率的效应。.

Introduction: Potentially painful invasive procedures are often performed for diagnostic or therapeutic purposes in hospitalised paediatric patients. Approaches, such as virtual reality (VR), should be sought in order to minimise pain and anxiety during these procedures. Materials and methods: Hospitalised patients between 4 and 15-years-old requiring an invasive procedure were included. Pain and anxiety evaluation scales were given to children, relatives and health workers. A comparison was made with patients in whom VR was used (with or without concomitant use of a prilocaine/lidocaine 2.5% analgesic cream) and patients in whom neither VR nor analgesic cream were used. Results: The study included 58 patients, 38 in the VR group and 20 in the control group. Pain scores, as performed by patients, relatives and health workers, significantly decreased in the VR group (control group median 4/5 vs. VR group median 1/5, P

Background Virtual reality (VR) technology may provide an effective means to integrate cognitive and functional approaches to TBI rehabilitation. However, little is known about the effectiveness of VR rehabilitation for TBI-related cognitive deficits. In response to these clinical and research gaps, we developed Neurocognitive Driving Rehabilitation in Virtual Environments (NeuroDRIVE), an intervention designed to improve cognitive performance, driving safety, and neurobehavioral symptoms. Objective This pilot clinical trial was conducted to examine feasibility and preliminary efficacy of NeuroDRIVE for rehabilitation of chronic TBI. Methods Eleven participants who received the intervention were compared to six wait-listed participants on driving abilities, cognitive performance, and neurobehavioral symptoms. Results The NeuroDRIVE intervention was associated with significant improvements in working memory and visual search/selective attention- two cognitive skills that represented a primary focus of the intervention. By comparison, no significant changes were observed in untrained cognitive areas, neurobehavioral symptoms, or driving skills. Conclusions Results suggest that immersive virtual environments can provide a valuable and engaging means to achieve some cognitive rehabilitation goals, particularly when these goals are closely matched to the VR training exercises. However, additional research is needed to augment our understanding of rehabilitation for driving skills, cognitive performance, and neurobehavioral symptoms in chronic TBI.

Background Needle phobias are common in children and adults worldwide. One effective intervention for this phobia is exposure therapy where a participant is gradually exposed to increasing levels of the fear-evoking stimulus while differential reinforcement is applied. This intervention, however, may be difficult to implement with some medical procedures as it may be difficult to obtain unfettered access to medical facilities and equipment for the purposes of exposure. Virtual reality may overcome these obstacles. Methods In this investigation, the present authors developed a low-cost virtual reality-based exposure therapy which was used with an adult male with autism spectrum disorder and a history of extreme needle phobia. The effectiveness of this intervention was evaluated using a changing criterions design with generalization probes. Results The intervention quickly increased the participant's compliance in the analogue training setting and the effects were generalized across settings and behaviours, and maintained over time. Conclusions The findings indicate combining virtual reality with exposure therapy may produce an effective intervention for medical phobias. The intervention package may remove barriers associate with traditional exposure therapy and was low-cost which may increase access to the intervention.

Background Balance training is an important aspect in prevention and rehabilitation of musculoskeletal lower limb injuries. Virtual reality (VR) is a promising addition or alternative to traditional training. This review aims to provide a comprehensive overview of VR technology and games employed for balance prevention and rehabilitation, balance outcome measures, and effects for both balance prevention and balance rehabilitation following musculoskeletal lower limb impairments. Methods A systematic literature search was conducted in electronic databases to identify all related articles with a longitudinal study design on VR, balance, and prevention or musculoskeletal rehabilitation of the lower limbs in adult subjects between 19 and 65 years. Results Eleven articles concerning balance prevention and five articles regarding balance rehabilitation were included. All studies used screen-based VR and off-the-shelf gaming consoles with accompanying games. The Star Excursion Balance Test (SEBT) was the most frequently used outcome measure. Two studies found positive effects of VR balance training in healthy adults, while none reported negative effects. None of the included studies showed a significant difference in balance performance after a VR balance rehabilitation intervention compared to traditional balance training. Conclusion Few studies have been published concerning musculoskeletal balance rehabilitation and balance prevention in healthy adult subjects. However, the studies published have shown that VR exercises are equally effective compared to traditional balance training for both domains of application. As there is large variability between studies, recommendations for future research are given to prospectively investigate the use of VR technology for balance training.

Neurorehabilitation is a fundamental aspect in the treatment approach for multiple sclerosis (MS), in which new technologies have gained popularity, especially the use of virtual reality (VR). The aim of this paper is to analyze an occupational therapy (OT) intervention compared with OT + VR (OT + VR) on the manual dexterity of patients with MS. 26 MS subjects were initially recruited from an MS patient association and randomized into two groups. The OT group received 20 conventional OT sessions distributed in two sessions per week. The OT + VR group received 20 sessions of VR interventions, twice weekly and lasting 30 minutes, consisting of VR games accessed via the online web pagemotiongamingconsole.com, in addition to the conventional OT sessions. Pre- and postintervention assessments were based on the Purdue Pegboard Test, the Jebsen-Taylor Hand Function Test, and the Grooved Pegboard Test. Clinical improvements were found regarding the precision of movements, the execution times, and the efficiency of certain functional tasks in the Purdue Pegboard Test and Jebsen-Taylor Hand Function Test tests in the OT + VR group. Although significant differences were not found in the manual dexterity between the OT and OT + VR groups, improvements were found regarding the precision and effectiveness of certain functional tasks.

Objective This study was designed to examine the feasibility of immersive virtual reality mirror therapy for upper limb paresis after stroke using a head-mounted display and provide preliminary evidence of efficacy. Design Ten outpatients with chronic stroke, upper limb hemiparesis, and a low predisposition for motion sickness completed a 12-session program of 30 mins each of immersive virtual reality mirror therapy. The virtual reality system provided the illusion of movement in the hemiparetic upper limb while suppressing the visual representation of the nonparetic side. Feasibility was assessed via patient compliance, adverse event tracking, the System Usability Scale, and the Simulator Sickness Questionnaire. Preliminary efficacy was evaluated using the Fugl-Meyer Upper Extremity and Action Research Arm Test. Results Immersive virtual reality mirror therapy for patients with chronic stroke was safe, well-tolerated, and without adverse events, such as simulator sickness. Motor outcomes revealed a small improvement for the Fugl-Meyer Upper Extremity from 21.7 (SD = 8.68) to 22.8 (SD = 9.19) that did not achieve statistical significance (P = 0.084). Conclusions Four weeks of immersive virtual reality mirror therapy was well-tolerated by chronic stroke patients. Our findings support further clinical trials of immersive virtual reality technologies and visually enhanced mirror therapies for stroke survivors.

Objective: To describe the intervention protocols to using commercial video games as virtual reality (VR) in rehabilitation of patients with stroke. Methods: Integrative review using the descriptors “rehabilitation”, “virtual reality exposure therapy” and “videogames” in the LILACS and PUBMED databases. Articles published from 2011 to 2018 were selected. Results: We found 1,396 articles, 1,383 were excluded and 13 were selected. Most of the articles were randomized clinical trials published in 2014 or later. The sample size varied from 5–47 adults, or adults and elders, with chronic stroke. The Nintendo Wii® was the most used video game system. The intervention happened two or three times a week, each session lasting from 30 to 60 minutes, over 2–12 weeks. Balance, upper limb motor functions, quality of life and daily living activities were the most common evaluated outcomes. The Fugl-Meyer Assessment, Berg Balance Scale, Timed Up and Go test, Barthel Scale and SF-36 were the most common outcome measurement tools. Conclusions: The studies indicated improvement in dynamic balance, upper limb motor function and quality of life after rehabilitation using VR. The VR was more effective than conventional treatments for the outcome of dynamic balance. Two studies did not find any changes in static balance and daily living activities. Physical aspects and quality of life were the outcomes most evaluated by the researchers; as were the population with chronic strokes and protocols of long duration and low intensity. Few studies targeted immediate VR effects, performance in daily living activities and social participation. RESUMO Objetivo: Descrever os protocolos de intervenção utilizando sistemas de vídeo game comerciais como realidade virtual (RV) na reabilitação de pacientes após AVE. Método: Revisão integrativa usando os descritores “reabilitação”, “terapia de exposição a realidade virtual” e “videogames”, nas bases de dados LILACS e PUBMED, e artigos publicados entre 2011 e 2018. Resultados: Foram encontrados 1.396, excluídos 1.383 e selecionados 13 artigos. A maioria era ensaio clínico aleatorizado publicados a partir de 2014. O tamanho da amostra variou de 5 a 47 participantes adultos ou adultos e idosos com AVE crônico. O Nintendo Wii® foi o videogame mais empregado. A intervenção constava de duas ou três sessões semanais, com duração de 30 ou 60 minutos por um período de duas a 12 semanas. Equilíbrio, função motora de membro superior, qualidade de vida e atividade de vida diária foram os principais desfechos. Empregou-se principalmente Escala Fugl-Meyer, Escala de Equilíbrio de Berg, teste Timed Up and Go, Índice de Barthel e SF-36 como medidas de desfecho. Conclusões: Os estudos indicaram melhora do equilíbrio dinâmico, função motora de membro superior e qualidade de vida após reabilitação usando RV. A RV se mostrou mais eficaz que tratamentos convencionais para o desfecho equilíbrio dinâmico. Dois estudos não encontraram mudanças no equilíbrio estático e atividade de vida diária. Observou-se maior foco em desfechos relacionados a aspectos físicos e qualidade de vida, em população com AVE crônico e protocolo com maior duração e menor intensidade. Poucos estudos voltados para efeitos imediatos da RV, desempenho em atividades de vida diária e participação social.

SUMMARY OBJECTIVE: This study aimed to investigate the effect of virtual reality application on experimental ischemic pain created with a blood pressure instrument in healthy volunteers. METHODS: The research sample consisted of 172 volunteer adult students who conformed to the inclusion criteria. These individuals were assigned into an experimental (n=86) and a control group (n=86) by a simple randomization method. All individuals in the experimental and control groups wereexperimentally subjected to pain for two minutes by applying 260 mmHg of pressure 3-4 cm above the antecubital region of the left arm with an aneroid adult-type blood pressure instrument. During the procedure, the volunteers in the experimental group watched virtual reality images, while those in the control group received no intervention. Immediately after the procedure, the pain levels of the individuals in both groups were assessed with a Visual Analog Scale (VAS). RESULTS: We found that the mean pain score of the individuals in the experimental group was 2.62±1.82, and that of individuals in the control group was 5.75±1.65. Results of the statistical analysis showed a statistically significant difference between the mean pain scores of the individuals in the experimental and control groups (p

Parents of children with Autism experience high levels of stress. Resiliency is the ability to cope and adapt when faced with stressful events. This randomized, waitlist controlled pilot trial examines the feasibility, acceptability, and preliminary efficacy of an adapted virtual mind–body group intervention for parents of children with ASD. The intervention was feasible and acceptable. The immediate treatment group showed no difference in distress and greater improvement in resiliency and stress reactivity/coping relative to the delayed treatment group, (M difference 5.78; p = .038 and M difference 7.78; p = .001 respectively). Findings showed promising feasibility, acceptability, and preliminary efficacy for parents of children with ASD.

Background: Although Virtual Reality Exposure Therapy (VRET) has proven to be effective in the treatment of various subtypes of specific phobia, there is limited evidence of its role in the treatment of dental phobia. Method: A single-blind RCT was conducted among 30 randomized patients with dental phobia to either VRET or informational pamphlet (IP) condition. Primary outcome anxiety measures (VAS-A, MDAS and DFS) were evaluated at baseline, pre- and post-intervention, 1-week, 3-months and 6-months follow-up. Secondary outcome measures assessed were pre-post behavioral avoidance, temporal variations of heart rate and VR-experience during and post-VRET, and dental treatment acceptance in both conditions at 6-month follow-up. Results: Intention to treat analysis, using a repeated measures MANOVA, revealed a multivariate interaction effect between time and condition (p = 0.015) for all primary outcome measures (all ps

Total knee arthroplasty (TKA) is one of the most popular surgeries in the orthopedic field. One of the reasons for a failed TKA is pain and difficulty to return to normal function. A pain control method that is becoming more and more popular is the use of virtual reality (VR). We aimed to examine VR intervention in the immediate post-operative physiotherapy following TKA.This prospective randomized-controlled study recruited a total of 55 patients undergoing primary TKA in a single institute, operated by three surgeons. They were assigned either study group or control group. Both groups were treated with conventional physiotherapy and CPM equipment (Continuous passive motion device), the study group received additional VR modality. Both groups completed a series of questionnaires prior and after the intervention: State-Trait Anxiety Inventory (STAI) questionnaire (used to diagnose anxiety), Visual analog scale (VAS) for pain and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) (knee function score).The average age was 70 years-old with equal distribution of male and female. Both groups showed a decrease in pain and anxiety following the intervention (p value 0.05) but there was no difference between the groups (p value 0.05 for all parameters). The was no difference in the WOMAC scores in the six-month post-operative examination between groups (p-value = 0.653).Virtual reality intervention in the immediate post-operative period following total knee arthroplasty decrease pain and anxiety but did not influence the pain, anxiety, and long-term function results more than conventional physiotherapy.

Key Points Question Does a virtual reality (VR) intervention compared with standard care improve pain and anxiety outcomes among patients undergoing peripheral intravenous catheter (PIVC) placement in the pediatric setting? Findings In this randomized clinical trial of 107 patients undergoing PIVC placement in 2 pediatric clinical settings plus their caregivers and clinicians, a VR intervention significantly reduced mean patient-reported post-PIVC anxiety and pain, caregiver-reported perceptions of patients’ pain, and clinician-reported perceptions of patients’ pain and anxiety. Meaning In this study, a VR intervention significantly decreased pain and anxiety among patients undergoing PIVC placement in the pediatric setting., This randomized clinical trial examines the effect of a virtual reality intervention vs standard care on pain and anxiety associated with peripheral intravenous catheter placement among patients receiving care in 2 pediatric clinical settings., Importance The inclusion of digital therapeutics (eg, virtual reality [VR] systems) for the management of pain and anxiety associated with routine acutely painful medical procedures may have a substantial impact on treatment adherence and improve long-term health outcomes among young patients. Objective To determine whether a VR intervention decreases pain and anxiety among patients undergoing peripheral intravenous catheter (PIVC) placement compared with standard care in the pediatric setting. Design, Setting, and Participants This randomized clinical trial was conducted from April 12, 2017, to July 24, 2019, among 107 patients aged 10 to 21 years who were undergoing PIVC placement in 2 clinical settings (a radiology department and an infusion center) at an urban pediatric academic medical center in the US. Patients, caregivers, and clinicians completed pre-PIVC and post-PIVC placement questionnaires measuring patient pain, anxiety, and anxiety sensitivity; only participants with complete data from before and after PIVC placment were included in the analyses. Interventions Patients were randomized to receive standard care (simple distraction techniques [eg, music, coloring, singing, and talking] and the application of numbing cream) or a VR intervention using a balanced computer-generated randomization scheme stratified by sex. All patients who received the VR intervention were offered concurrent standard care; however, VR plus standard care was not specifically examined. Main Outcomes and Measures Primary outcomes were patient pain (measured by the Faces Pain Scale–Revised) and anxiety (measured by a visual analogue scale) reported by the patient, caregiver, and clinician after PIVC placement. Outcomes were analyzed using generalized linear modeling with backward stepwise selection for final model building. Results A total of 107 patients (median age, 14.7 years [interquartile range, 12.8-16.9 years]; 63 male participants [58.9%]) completed the clinical trial; 54 patients received standard care, and 53 patients also received the VR intervention. Patients who received the VR intervention compared with standard care had significantly lower mean post-PIVC anxiety scores when patient-reported (1.85 points [95% CI, 1.28-2.41 points] vs 3.14 points [95% CI, 2.59-3.68 points]; P

ObjectiveVisual-vestibular mismatch patients experience persistent postural and perceptual dizziness. Previous studies have shown the benefit of vestibular rehabilitation for visual desensitisation using gaze stabilisation exercises and optokinetic stimulation. This study assessed the benefit of customised vestibular rehabilitation with visual desensitisation and virtual reality based therapy rehabilitation in the management of patients with persistent postural-perceptual dizziness.MethodsThis retrospective study included 100 patients with Situational Characteristic Questionnaire scores of more than 0.9. All patients received virtual reality based therapy along with usual vestibular rehabilitation using gaze stabilisation exercises with a plain background followed by graded visual stimulation and optokinetic digital video disc stimulation. Patients’ symptoms were assessed before and after vestibular rehabilitation using the Situational Characteristic Questionnaire, Generalised Anxiety Disorder Assessment-7, Nijmegen Questionnaire and Dizziness Handicap Inventory.ResultsThere were statistically significant improvements in Situational Characteristic Questionnaire scores, Nijmegen Questionnaire scores and Dizziness Handicap Inventory total score. However, there was a statistically insignificant difference in Generalised Anxiety Disorder Assessment-7 scores. There was a significant positive correlation between post-rehabilitation Situational Characteristic Questionnaire scores and other questionnaire results.ConclusionIncorporating virtual reality based therapy with customised vestibular rehabilitation exercises results in significant improvement in persistent postural-perceptual dizziness related symptoms.

Many have expressed concerns about the safety and ethics of conducting suicide research, especially intense suicide research methods that expose participants to graphic depictions of suicidality. We conducted two studies to evaluate the effects of one such method called virtual reality (VR) suicide. Study 1 tested the effects of VR suicide exposure over the course of one month in participants with (n = 56) and without a history of suicidality (n = 50). Study 2 exposed some participants to VR suicide scenarios (n = 79) and others to control scenarios (n = 80). Participants were invited to complete a follow-up assessment after an average of 2 years. For both studies, the presence of suicidality post exposure was the primary outcome, with closely related constructs (e.g., capability for suicide, agitation) as secondary outcomes. Study 1 found no pre-post increases in suicidality or related variables, but revealed several significant decreases associated with small to medium effect sizes in suicide-related constructs. In Study 2, VR suicide exposure did not cause any significant increases in suicidality or related variables. Together with prior research, these findings suggest that methods involving intense suicide stimuli appear safe and consistent with utilitarian ethics.

Virtual reality facilitates physical therapy via improved engagement. Although shown to benefit specific patient populations, such as stroke patients, it is less established in otherwise healthy adults and children receiving outpatient physical therapy. The primary objective was to compare total physical therapy-guided movement supplemented with virtual reality with physical therapy-guided movement alone without virtual reality.This pragmatic, randomized, crossover study compared physical therapy-guided movement supplemented with virtual reality with physical therapy-guided movement alone without virtual reality in outpatients (ages 6-80 yrs). This community sample had variable physical therapy indications (injury, postoperative, chronic pain), and in pre-existing conditions, therefore, participants served as their own controls. Participants received 10 mins of both physical therapy-guided movement supplemented with virtual reality and physical therapy-guided movement alone without virtual reality separated by 5 mins. The primary outcome was differences in aggregate movement of physical therapy-guided exercises. Secondary outcomes explored OMNI rating of perceived exertion and participant and physical therapist satisfaction. Paired t tests, χ2 tests, and regression models were used to analyze differences.The 41 participants (17 pediatric and 24 adult) moved significantly more during physical therapy-guided movement supplemented with virtual reality compared with physical therapy-guided movement alone without virtual reality (1120.88 vs. 672.65 m, P0.001), regardless of which intervention was completed first. Physical therapy-guided movement supplemented with virtual reality treatment was associated with more movement of the target limbs, lower body (P0.001), and upper body (P0.05). The OMNI rating of perceived exertion scores did not differ between those who started with physical therapy-guided movement supplemented with virtual reality or physical therapy-guided movement alone without virtual reality, and physical therapist and patient surveys endorsed physical therapy-guided movement supplemented with virtual reality.Patients completed more physical therapy-guided movement during physical therapy-guided movement supplemented with virtual reality than physical therapy-guided movement alone without virtual reality, and therapists and patients supported its use. Future studies will examine finer tracking of movements.

Background Cue exposure for extinguishing conditioned urges to smoking cues has been promising in the laboratory, but difficult to implement in natural environments. The recent availability of augmented reality (AR) via smartphone provides an opportunity to overcome this limitation. Testing the ability of AR to elicit cue-provoked urges to smoke (ie, cue reactivity [CR]) is the first step to systemically testing the efficacy of AR for cue exposure therapy. Objectives To test CR to smoking-related AR cues compared to neutral AR cues, and compared to in vivo cues. Methods A 2 × 2 within-subject design comparing cue content (smoking vs. neutral) and presentation modality (AR vs. in vivo) on urge response. Seventeen smokers viewed six smoking-related and six neutral cues via AR smartphone app and also six smoking and six neutral in vivo cues. Participants rated their urge to smoke and reality/co-existence of the cue. Results Average urge to smoke was higher following smoking-related AR images (Median = 7.50) than neutral images (Median = 3.33) (Z = −3.44; p = .001; d = 1.37). Similarly, average urge ratings for in vivo smoking-related cues (Median = 8.12) were higher than for neutral cues (Median = 2.12) (Z = −3.44; p = .001; d = 1.64). Also, greater CR was observed for in vivo cues than for AR cues (Z = −2.67, p = .008; d = .36). AR cues were generally perceived as being realistic and well-integrated. Conclusions CR was demonstrated with very large effect sizes in response to AR smoking cues, although slightly smaller than with in vivo smoking cues. This satisfies the first criterion for the potential use of AR for exposure therapy. Implications This study introduces AR as a novel modality for presenting smoking-related stimuli to provoke cue reactivity, and ultimately to conduct extinction-based therapy. AR cues presented via a smartphone have the advantage over other modes of cue presentation (pictures, virtual reality, in vivo, etc.) of being easily transportable, affordable, and realistic, and they can be inserted in a smokers’ natural environment rather than being limited to laboratory and clinic settings. These AR features may overcome the generalizability barriers of other methods, thus increasing clinical utility for cue exposure therapies.

Background Recently, there is an increased number of studies that use 360° virtual reality (VR) video for medical and rehabilitative purposes. However, the 360° VR video experience for older adults has not yet been investigated. This study aimed to examine the validity of an 360° VR video-based immersive cycling training system (360° VRCTS) for older adults and to provide preliminary evidence of efficacy. Methods We developed a new virtual reality training system using an immersive environment 360° VRCTS. Five healthy older adults (2 males and 3 females) participated in this study. The system was tested in a single training session (biking for 20 min while viewing a 360° VR video scene through a large curved screen) to identify its strengths and weakness. The usability and acceptability of our system were measured using the system usability scale (SUS) and the simulator sickness questionnaire (SSQ). Results All participants successfully completed the session without any discomfort. The average score for the SUS was 94.60 (range, 90–100), indicating high usability of the technology. The average score for the SSQ was 2.24 (standard deviation = 2.05), indicating that the system is well tolerated and has few side effects. Conclusions The 360° VRCTS may be a useful indoor training system for older adults due to its easy manipulation, high usability, and limited cybersickness.

Cerebrovascular accident, or stroke, is a leading cause of serious long-term disability, and incidence is expected to continue rising in the coming years. Stroke-related disability can manifest as motor, sensory, or cognitive impairment, and although current therapies can improve these impairments, many stroke patients are still left with reduced abilities and struggle to maintain independence in their daily lives. Virtual reality (VR) has been proposed as a novel therapeutic tool to treat stroke-related disability, particularly in conjunction with traditional post-stroke therapies.Here, we report 1 case of a 75-year-old male with ongoing right upper extremity impairment.The patient was previously diagnosed with an ischemic stroke.Seven years post-stroke, during which he did not receive any therapies, and on the recommendation of his neurologist, the patient sought VR therapy as an innovative treatment strategy. His clinicians employed a combination of traditional exercise and VR therapy to improve his strength and mobility.The combination of traditional and VR therapy was able to provide meaningful improvement to his daily quality of life, even years after the stroke.These results suggest that combination therapy with VR is a viable tool for treating post-stroke impairment, even several years on from the cerebrovascular accident.

Older adults who require bicycle training devices can improve muscle strength and balance of lower limbs by continuously contracting and relaxing lower-limb muscles and improving cognitive function to prevent dementia. This study was conducted to investigate the effects of an ICT-based multicomponent program on body composition and cognitive function in older adults.Patients and Methods: In a randomized controlled intervention test on 20 people over the age of 60 (exercise group: n = 10; control: n = 10), the multicomponent program was applied to the exercise group twice per week, once per day for 12 weeks, at 30 min per session, whereas the control group was advised to maintain their usual daily activities.Results: Comparing body composition changes and cognitive function changes before and after intervention exhibited statistically significant differences in skeletal muscle mass (P=0.01) and modified Alzheimer’s disease assessment scale–cognitive score (P=0.01) between the two groups.Conclusion: It can be difficult to be engaged in a simple repetitive exercise program. Therefore, to meet older adults’ interests and expectations, a customized ICT-based multicomponent program, which can improve body composition and cognitive function in older adults and is believed to help prevent dementia, is recommended.Trial Registration: UMIN000042129 (https://www.umin.ac.jp/english/).Keywords: ICT-based multicomponent program, body composition, cognitive function, dementia, older adults

Depression and anxiety can significantly reduce the effectiveness of cardiac rehabilitation (CR). Several studies have assessed the effectiveness of virtual reality (VR)-based interventions for symptoms of anxiety and depression; however, they do not relate to patients with heart disease. The aim of this study was to assess the effects of VR therapy on the mental state of patients with coronary artery disease (CAD). Thirty-four CAD patients with elevated anxiety or depression symptoms were recruited. After randomization, 17 participants were assigned to the intervention group, and 17 to the control group. Both groups underwent standard CR for outpatients. In the intervention group, eight VR therapy sessions were applied. In the control group, eight sessions of Schultz’ Autogenic Training were applied. To assess patient mental states, Hospital Anxiety and Depression Scale (HADS) and Perception of Stress Questionnaire (PSQ) were used, before and after 4 weeks of CR. In the intervention group, a significant decrease in HADS score was observed (19.46 pretreatment vs. 15.73 post-treatment, p = 0.003), HADS-Anxiety subscale decreased by 16.0 percent (p = 0.01) and HADS-Depression by 23.0 percent (p = 0.003). Similarly, a significant decrease in PSQ was recorded at 12.8 percent (64.73 vs. 56.47, p = 0.03). In the control group, HADS and PSQ data did not change. VR therapy significantly reduced the severity of depressive symptoms, anxiety, and stress levels in CAD patients undergoing CR. Immersive VR therapy effectively supports the CR of individuals with anxiety-depressive symptoms. ClinicalTrials.gov (NCT04045977)

Background Vestibular compensation is disrupted in patients with chronic vestibular syndrome. Vestibular rehabilitation is an exercise therapy that optimizes the process of vestibular compensation. This study aimed to evaluate virtual reality (VR) vestibular rehabilitation in 20 patients with vertigo due to peripheral vestibular dysfunction at a single center. Our study aim was to initially assess the impact of using virtual reality technology in vestibular rehabilitation. Material/Methods The subjects were 20 patients with unilateral vestibular hypofunction (UVH), as confirmed by videonystagmography. These were divided into 2 groups: Group 1 underwent vestibular rehabilitation using virtual reality and Group 2 was treated by conventional therapy. A VSS-SF questionnaire and the VAS scale were used to assess the effects and levels of patient satisfaction with therapy. Results Both groups demonstrated significantly (P

Background Using fractional flow reserve (FFR) to guide percutaneous coronary intervention for patients with coronary artery disease (CAD) improves clinical decision making but remains under-used. Virtual FFR (vFFR, computed from angiographic images) permits physiological assessment without a pressure wire and can be extended to virtual coronary intervention (VCI) facilitating treatment planning. This study investigated the effect of adding vFFR and VCI to angiography in patient assessment and management. Methods Two cardiologists independently reviewed clinical data and angiograms of 50 patients undergoing invasive management of coronary syndromes, and their management plans were recorded. The vFFRs were computed and disclosed, and the cardiologists submitted revised plans. Then, using VCI, the physiological results of various interventional strategies were shown, and further revision was invited. Results Disclosure of vFFR led to a change in strategy in 27%. VCI led to a change in stent size in 48%. Disclosure of vFFR and VCI resulted in an increase in operator confidence in their decision. Twelve cases were reviewed by six additional cardiologists. There was limited agreement in the management plans between cardiologists based upon either angiography (kappa=0.31) or vFFR (kappa=0.39). Conclusions vFFR has the potential to alter decision making, and VCI can guide stent sizing. However, variability in management strategy remains considerable between operators, even when presented with the same anatomical and physiological data.

Background: Virtual reality (VR) based digital practice is an attractive way to provide a patient engagement, motivation and adaptable environment for stroke rehabilitation. However, clinical evidence of efficacy with VR-based digital practice is very limited. In this study, we investigated the effects of VR-based digital practice program on unilateral spatial neglect (USN) rehabilitation in patients with subacute stroke. Methods: Twenty-four subacute stroke patients with USN were enrolled and randomly assigned to digital practice group (n = 12) and control group (n = 12). Patients in digital practice group received training programs with VR-based applications with leap motion environment. Control group received conventional USN specific training programs. All patients were underwent 4 week practice program (3 sessions/week, a half-hour/session). We analyzed training effects before and after training by assessing the line bisection test, Catherine Bergego Scale, modified Barthel index, Motor-Free Visual Perception Test Vertical Version (MVPT-V), and horizontal head movements (rotation degree and velocity during the VR-based applications), and compared the results between the two groups. Results: Compared to control group, digital practice group showed significantly greater improvements in the line bisection test (P = .020), and visual perceptual tasks (MVPT-V, responded more on left visual task, P = .024; correctly respond more on both left and right visual tasks, P = .024 and P = .014, respectively; and faster response time, P = .014). Additionally, horizontal head movement of rotation degree and velocity during the VR based practice in the digital practice group were significantly increased more than control group (P = .007 and P = .001, respectively). Conclusions: VR-based digital practice program might be an affordable approach for visual perception and head movement recovery for subacute stroke patients with USN.

Background The high incidence of cerebral apoplexy makes it one of the most important causes of adult disability. Gait disorder is one of the hallmark symptoms in the sequelae of cerebral apoplexy. The recovery of walking ability is critical for improving patients’ quality of life. Innovative virtual reality technology has been widely used in post-stroke rehabilitation, whose effectiveness and safety have been widely verified. To date, however, there are few studies evaluating the effect of immersive virtual reality on stroke-related gait rehabilitation. This study outlines the application of immersive VR-assisted rehabilitation for gait rehabilitation of stroke patients for comparative evaluation with traditional rehabilitation. Methods The study describes a prospective, randomized controlled clinical trial. Thirty-six stroke patients will be screened and enrolled as subjects within 1 month of initial stroke and randomized into two groups. The VRT group (n = 18) will receive VR-assisted training (30 min) 5 days/week for 3 weeks. The non-VRT group (n = 18) will receive functional gait rehabilitation training (30 min) 5 days/week for 3 weeks. The primary outcomes and secondary outcomes will be conducted before intervention, 3 weeks after intervention, and 6 months after intervention. The primary outcomes will include time “up & go” test (TUGT). The secondary outcomes will include MMT muscle strength grading standard (MMT), Fugal-Meyer scale (FMA), motor function assessment scale (MAS), improved Barthel index scale (ADL), step with maximum knee angle, total support time, step frequency, step length, pace, and stride length. Discussion Virtual reality is an innovative technology with broad applications, current and prospective. Immersive VR-assisted rehabilitation in patients with vivid treatment scenarios in the form of virtual games will stimulate patients’ interest through active participation. The feedback of VR games can also provide patients with performance awareness and effect feedback, which could be incentivizing. This study may reveal an improved method of stroke rehabilitation which can be helpful for clinical decision-making and future practice.

Background Virtual reality (VR) is an evolving technology that is becoming a common treatment for pain management and psychologic phobias. Although nonimmersive devices (e.g., the Nintendo Wii) have been previously tested with patients on hemodialysis, no studies to date have used fully immersive VR as a tool for intervention delivery. This pilot trial tests the initial safety, acceptability, and utility of VR during maintenance hemodialysis treatment sessions—particularly, whether VR triggers motion sickness that mimics or negatively effects treatment-related symptoms (e.g., nausea). Methods Patients on hemodialysis (n=20) were enrolled in a phase 1 single-arm proof-of-concept trial. While undergoing hemodialysis, participants were exposed to our new Joviality VR program. This 25-minute program delivers mindfulness training and guided meditation using the Oculus Rift head-mounted display. Participants experienced the program on two separate occasions. Before and immediately after exposure, participants recorded motion-related symptoms and related discomfort on the Simulator Sickness Questionnaire. Utility measures included the end-user’s ability to be fully immersed in the virtual space, interact with virtual objects, find hardware user friendly, and easily navigate the Joviality program with the System Usability Scale. Results Mean age was 55.3 (±13.1) years; 80% male; 60% Black; and mean dialysis vintage was 3.56 (±3.75) years. At the first session, there were significant decreases in treatment and/or motion-related symptoms after VR exposure (22.6 versus 11.2; P=0.03); scores >20 indicate problematic immersion. Hemodialysis end-users reported high levels of immersion in the VR environment and rated the software easy to operate, with average System Usability Scale scores of 82.8 out of 100. Conclusions Patients on hemodialysis routinely suffer from fatigue, nausea, lightheadedness, and headaches that often manifest during their dialysis sessions. Our Joviality VR program decreased symptom severity without adverse effects. VR programs may be a safe platform to improve the experience of patients on dialysis.

Objectives. This study is aimed at exploring the effects of virtual reality (VR) training on postural control, measured by anticipatory and compensatory postural adjustments (APAs and CPAs, respectively), in patients with chronic nonspecific low back pain (CNLBP) and the potential neuromuscular mechanism of VR training. Methods. Thirty-four patients were recruited and randomly assigned to the VR group ( n = 11 ), the motor control exercise group (MCE, n = 12 ) and the control group (CG, n = 11 ). The VR group received VR training using Kinect Xbox 360 systems and magnetic therapy. Besides magnetic therapy, the participants in the MCE group performed real-time ultrasound-guided abdominal drawing-in maneuver (ADIM) and four-point kneeling exercise. The CG only received magnetic therapy. Surface muscle electromyography (sEMG) was used to record the muscle activities of transverse abdominis (TrA), multifidus (MF), lateral gastrocnemius (LG), and tibialis anterior (TA) during ball-hitting tasks. The muscle activation time and integrals of the electromyography activities (IEMGs) during the APA and CPA stages were calculated and used in the data analysis. The visual analogue scale (VAS) and Oswestry dysfunction index (ODI) scores were also recorded. Results. A significant interaction effect of time × group was observed on the activation time of TrA ( p = 0.018 ) and MF ( p = 0.037 ). The post-intervention activation time of the TrA was earlier in the VR group ( p = 0.029 ). In contrast, the post-intervention activation time of the MF was significantly delayed in the VR group ( p = 0.001 ). The IEMGs of TrA ( p = 0.002 ) and TA ( p = 0.007 ) during CPA1 significantly decreased only in the VR group after the intervention. The VAS scores of three group participants showed significant decreases after intervention ( p < 0.001 ). Conclusions. Patients with CNLBP showed reciprocal muscle activation patterns of the TrA and MF muscles after VR training. VR training may be a potential intervention for enhancing the APAs of the patients with CNLBP.
