Abstract

Abstract Background Illusion of movement induced by tendon vibration is commonly used in rehabilitation and seems valuable for motor rehabilitation after stroke, by playing a role in cerebral plasticity. The aim was to study if congruent visual cues using Virtual Reality (VR) could enhance the illusion of movement induced by tendon vibration of the wrist among participants with stroke. Methods We included 20 chronic stroke participants. They experienced tendon vibration of their wrist (100 Hz, 30 times) inducing illusion of movement. Three VR visual conditions were added to the vibration: a congruent moving virtual hand (Moving condition); a static virtual hand (Static condition); or no virtual hand at all (Hidden condition). The participants evaluated for each visual condition the intensity of the illusory movement using a Likert scale, the sensation of wrist’s movement using a degree scale and they answered a questionnaire about their preferred condition. Results The Moving condition was significantly superior to the Hidden condition and to the Static condition in terms of illusion of movement (p

Abstract

Stroke is a severe health issue, and motor recovery after stroke remains an important challenge in the rehabilitation field. Neurofeedback (NFB), as part of a brain–computer interface, is a technique for modulating brain activity using on-line feedback that has proved to be useful in motor rehabilitation for the chronic stroke population in addition to traditional therapies. Nevertheless, its use and applications in the field still leave unresolved questions. The brain pathophysiological mechanisms after stroke remain partly unknown, and the possibilities for intervention on these mechanisms to promote cerebral plasticity are limited in clinical practice. In NFB motor rehabilitation, the aim is to adapt the therapy to the patient’s clinical context using brain imaging, considering the time after stroke, the localization of brain lesions, and their clinical impact, while taking into account currently used biomarkers and technical limitations. These modern techniques also allow a better understanding of the physiopathology and neuroplasticity of the brain after stroke. We conducted a narrative literature review of studies using NFB for post-stroke motor rehabilitation. The main goal was to decompose all the elements that can be modified in NFB therapies, which can lead to their adaptation according to the patient’s context and according to the current technological limits. Adaptation and individualization of care could derive from this analysis to better meet the patients’ needs. We focused on and highlighted the various clinical and technological components considering the most recent experiments. The second goal was to propose general recommendations and enhance the limits and perspectives to improve our general knowledge in the field and allow clinical applications. We highlighted the multidisciplinary approach of this work by combining engineering abilities and medical experience. Engineering development is essential for the available technological tools and aims to increase neuroscience knowledge in the NFB topic. This technological development was born out of the real clinical need to provide complementary therapeutic solutions to a public health problem, considering the actual clinical context of the post-stroke patient and the practical limits resulting from it.

Abstract

IntroductionMotor Imagery (MI) is a powerful tool to stimulate sensorimotor brain areas and is currently used in motor rehabilitation after a stroke. The aim of our study was to evaluate whether an illusion of movement induced by visuo-proprioceptive immersion (VPI) including tendon vibration (TV) and Virtual moving hand (VR) combined with MI tasks could be more efficient than VPI alone or MI alone on cortical excitability assessed using Electroencephalography (EEG).MethodsWe recorded EEG signals in 20 healthy participants in 3 different conditions: MI tasks involving their non-dominant wrist (MI condition); VPI condition; and VPI with MI tasks (combined condition). Each condition lasted 3 minutes, and was repeated 3 times in randomized order. Our main judgment criterion was the Event-Related De-synchronization (ERD) threshold in sensori-motor areas in each condition in the brain motor area.ResultsThe combined condition induced a greater change in the ERD percentage than the MI condition alone, but no significant difference was found between the combined and the VPI condition (p = 0.07) and between the VPI and MI condition (p = 0.20).ConclusionThis study demonstrated the interest of using a visuo-proprioceptive immersion with MI rather than MI alone in order to increase excitability in motor areas of the brain. Further studies could test this hypothesis among patients with stroke to provide new perspectives for motor rehabilitation in this population.

Abstract

Objective: To evaluate recurrence and early post-operative complications (sepsis) following surgical excision combined with radiotherapy for trouble-some hip heterotopic ossification in patients with spinal cord injury and traumatic brain injury. Design: Retrospective case-control study. Setting: Data relating to patients with spinal cord injury or traumatic brain injury who underwent surgical excision of hip heterotopic ossification were retrieved from the BANKHO database. Case patients underwent excision + radiotherapy, and controls underwent excision only. Control patients were matched to case patients according to sex and age (± 4 years). Participants: Data from 19 case patients and 76 controls were analysed. Main outcome measure: The primary end-point was recurrence of heterotopic ossification. Secondary end-points were postoperative complications and, more specifically, sepsis that required surgical revision. Results: There was no difference between the odds ratios (OR) for recurrence for each group (OR case group = 0.63, OR spinal cord injury subgroup = 0.45 and OR head injury subgroup = 1.04). The rate of sepsis requiring surgical revision was significantly higher in the case group (p

Abstract

Traditional rehabilitation techniques present limitations and the majority of patients show poor 1-year post-stroke recovery. Thus, Neurofeedback (NF) or Brain-Computer-Interface applications for stroke rehabilitation purposes are gaining increased attention. Indeed, NF has the potential to enhance volitional control of targeted cortical areas and thus impact on motor function recovery. However, current implementations are limited by temporal, spatial or practical constraints of the specific imaging modality used. In this pilot work and for the first time in literature, we applied bimodal EEG-fMRI NF for upper limb stroke recovery on four stroke-patients with different stroke characteristics and motor impairment severity. We also propose a novel, multi-target training approach that guides the training towards the activation of the ipsilesional primary motor cortex. In addition to fMRI and EEG outcomes, we assess the integrity of the corticospinal tract (CST) with tractography. Preliminary results suggest the feasibility of our approach and show its potential to induce an augmented activation of ipsilesional motor areas, depending on the severity of the stroke deficit. Only the two patients with a preserved CST and subcortical lesions succeeded in upregulating the ipsilesional primary motor cortex and exhibited a functional improvement of upper limb motricity. These findings highlight the importance of taking into account the variability of the stroke patients’ population and enabled to identify inclusion criteria for the design of future clinical studies.

Abstract

BACKGROUND:Findings regarding the impact of language bias on treatment effect estimates (TEE) are conflicting, and very few studies have assessed these impacts in rehabilitation. The purpose was to compare TEE between studies published in non-English language (SPNEL) and those published in English language (SPEL) included in a previously published meta-analysis assessing the effects of physical therapy on balance and postural control after stroke. METHODS:Six databases were searched until January 2019. Two independent reviewers selected randomised trials, extracted data, and assessed risk of bias. We conducted subgroup meta-analyses according to the language of study publication, then compared TEE between SPEL and SPNEL subgroups by using a random-effects meta-regression model. RESULTS:From 13,123 records, 132 SPEL (n = 5219) and 13 SPNEL (n = 693) were included. SPNEL had a weight in the pooled estimate (8.2%) significantly lower than SPEL (91.8%; p

Abstract

IntroductionIllusion of movement induced by tendon vibration is an effective approach for motor and sensory rehabilitation in case of neurological impairments. The aim of our study was to investigate which modality of visual feedback in Virtual Reality (VR) associated with tendon vibration of the wrist could induce the best illusion of movement.MethodsWe included 30 healthy participants in the experiment. Tendon vibration inducing illusion of movement (wrist extension, 100Hz) was applied on their wrist during 3 VR visual conditions (10 times each): a moving virtual hand corresponding to the movement that the participants could feel during the tendon vibration (Moving condition), a static virtual hand (Static condition), or no virtual hand at all (Hidden condition). After each trial, the participants had to quantify the intensity of the illusory movement on a Likert scale, the subjective degree of extension of their wrist and afterwards they answered a questionnaire.ResultsThere was a significant difference between the 3 visual feedback conditions concerning the Likert scale ranking and the degree of wrist's extension (pConclusionsThis study demonstrated the importance of carefully selecting a visual feedback to improve the illusion of movement induced by tendon vibration, and the increase of illusion by adding VR visual cues congruent to the illusion of movement. Further work will consist in testing the same hypothesis with stroke patients.

Abstract

(1) Background: Humans use reference frames to elaborate the spatial representations needed for all space-oriented behaviors such as postural control, walking, or grasping. We investigated the neural bases of two egocentric tasks: the extracorporeal subjective straight-ahead task (SSA) and the corporeal subjective longitudinal body plane task (SLB) in healthy participants using functional magnetic resonance imaging (fMRI). This work was an ancillary part of a study involving stroke patients. (2) Methods: Seventeen healthy participants underwent a 3T fMRI examination. During the SSA, participants had to divide the extracorporeal space into two equal parts. During the SLB, they had to divide their body along the midsagittal plane. (3) Results: Both tasks elicited a parieto-occipital network encompassing the superior and inferior parietal lobules and lateral occipital cortex, with a right hemispheric dominance. Additionally, the SLB > SSA contrast revealed activations of the left angular and premotor cortices. These areas, involved in attention and motor imagery suggest a greater complexity of corporeal processes engaging body representation. (4) Conclusions: This was the first fMRI study to explore the SLB-related activity and its complementarity with the SSA. Our results pave the way for the exploration of spatial cognitive impairment in patients.

Abstract

BackgroundStroke results in balance disorders and these directly affect autonomy and quality of life. The purpose of this systematic review and meta-analysis was to determine the efficacy of physical therapy (PT) on balance and postural control after stroke.MethodsWe included all randomized controlled trials assessing the efficacy of PT on balance and postural control in adult patients after stroke without language restriction. Medline, Embase/Scopus, Cochrane Central Register of Controlled Trials, PEDro, Pascal, and Francis databases were searched until January 2019. Primary outcomes were balance (Berg Balance scale and Postural Assessment Scale for Stroke) and postural control with postural deviation or stability measurement in sitting or standing static evaluation. A pair of independent reviewers selected studies, extracted data, and assessed risk of bias. Meta-analyses with subgroups (categories of PT, time post-stroke, and lesion location) and meta-regression (duration of PT) were conducted.ResultsA total of 145 studies (n = 5912) were selected from the 13,123 records identified. For balance, evidence was found in favor of the efficacy of functional task-training alone (standardized mean difference 0.39, 95% confidence interval [0.09; 0.68], heterogeneity I2 = 63%) or associated with musculoskeletal intervention and/or cardiopulmonary intervention (0.37, [0.19; 0.55], I2 = 48%), electrostimulation (0.91, [0.49; 1.34], I2 = 52%) immediately after intervention, compared to sham treatment or usual care (ST/UC). For postural deviation eyes open, assistive devices were more effective than no treatment (-0.21, [-0.37; -0.05], I2 = 0%) immediately after intervention; for postural stability eyes open, functional task-training and sensory interventions were more effective than ST/UC (0.97, [0.35; 1.59], I2 = 65% and 0.80, [0.46; 1.13], I2 = 37% respectively) immediately after intervention.ConclusionsFunctional task-training associated with musculoskeletal intervention and/or cardiopulmonary intervention and sensory interventions seem to be immediately effective in improving balance and postural stability, respectively. The heterogeneity of PT and the weak methodological quality of studies limited the interpretation and the confidence in findings.

Abstract

International audience; Purpose: To assess the reliability and minimal detectable change (MDC) of weight-bearing asymmetry (WBA) and body sway (BS) during "eyes open" (EO) and "eyes closed" (EC) conditions for those with right brain damage (RBD) and left brain damage (LBD) at a chronic stage.Methods: Sixteen RBD and 16 LBD patients participated in two sessions within 15 days, composed of two trials of 30 s using a double force platform. Intraclass correlation coefficient (ICC2,1), the standard error of measurement (SEM), and MDC were calculated for WBA and BS (area and velocity of sway).Results: Reliability of WBA was excellent (>0.75) except for EC for LBD patients (low SEM was found). The condition of EC was similar to or less reliable than that of EO. The MDC of WBA was 5.4 and 7.3% for LBD and RBD patients, respectively. Velocity of sway should be favored over the area of sway due to better reliability, with an MDC of 9 and 13 mm/s for RBD and LBD patients, respectively.Conclusions: Parameters related to WBA and BS were highly reliable, without a difference between RBD and LBD patients, but less so in the condition of EC, and could be used for clinical rehabilitation and/or research.Implications for rehabilitationWeight-bearing asymmetry (WBA) and body sway (BS) are highly reliable posturography parameters.Reliability of WBA/BS is similar among right brain damaged (RBD) and left brain damaged (LBD) patients.A change of 5-7% can be interpreted as significant for WBA for chronic stroke.The minimal detectable change in measures is slightly higher for RBD patients.

Abstract

International audience; We investigate how underfoot vibrotactile feedback can be used to increase the impression of walking and embodiment of static users represented by a first- or third-person avatar. We designed a multi-sensory setup involving avatar displayed on an HMD, and a set of vibrotactile effects displayed at every footstep. In a first study (N = 44), we compared the impression of walking in 3 vibrotactile conditions : 1) with a ”constant” vibrotactile rendering reproducing simple contact information, 2) with a more sophisticated ”phase-based” vibrotactile rendering the successive contacts of a walking cycle and 3) without vibrotactile feedback. The results show that overall both constant and phase-based rendering significantly improve the impression of walking in first and third-person perspective. Interestingly, the more realistic phase-based rendering seems to increase significantly the impression of walking in the third-person condition, but not in the first-person condition. In a second study (N=28), we evaluated the embodiment towards first- andthird-person avatar while receiving no vibrotactile feedback or by receiving vibrotactile feedback. The results show that vibrotactile feedback improves embodiment in both perspectives of the avatar. Taken together, our results support the use of vibrotactile feedback when users observe first- and third-person avatar. They also suggest that constant and phase-based rendering could be used with first-person avatar and support the use of phase-based rendering with third-person avatar. They provide valuable insight for stimulations in any VR applications in which the impression of walking is prominent such as for virtual visits, walking rehabilitation, video games, etc.

Abstract

International audience; Background: Upper limb movement patterns have not yet been identified in bimanual conditions despite the difficulties children with unilateral cerebral palsy have performing bimanual activities. The aim was to identify specific motor patterns from kinematic deviations during bimanual tasks in this population. Methods: Twenty children with unilateral cerebral palsy and 20 age-matched, typically developing children performed the five tasks of a 3D bimanual protocol. To evaluate upper limb kinematic deviations, 10 Arm Variable Scores were calculated for the affected /non-dominant upper limb of each participant for each task. Sparse K-means cluster analysis was applied to the 50 Arm Variable Scores of all the children to identify motor patterns and determining variables. Clinical tests of impairment (muscle strength, selectivity, spasticity) and function (Assisting hand assessment, Abilhand-Kids) were compared between the clusters obtained. Findings: Three different motor patterns were identified using the data from all the children: mild, proximal-distal and proximal-distal with trunk. The most important cluster determinants were the Arm Variable Scores for pronation-supination and wrist extension. In the cerebral palsy group, scores of impairments (p < .01) and function (Assisting Hand Assessment [p < .0011 and Abilhand-Kids [p = .0041) differed for each motor pattern. Supination and wrist extension deviations differed significantly between the groups (p < .001). Interpretation: During performance of bimanual tasks, children with unilateral cerebral palsy used distinct motor patterns that each corresponded to a specific clinical profile. Elbow-wrist deviations were the largest and most decisive and were specific to the cerebral palsy group: they should be the target of interventions to enhance bimanual function.

Abstract

International audience; Background: Scoliosis develops in a proportion of children with myelomeningocele; however, little is known about scoliosis in adulthood and in other forms of spina bifida (SB). Objectives: The aims of this study were to describe the prevalence of scoliosis and identify risk factors for its development in a large cohort of adults with open and closed SB. Methods: This was a cross-sectional study of data from 580 adults with SB attending their first consultation at a French multidisciplinary referral centre for SB. Sex, anatomical location and type of SB (open or closed), neurological level, back pain and ambulatory status (new Functional Ambulation Classification [new FAC]) were compared in adults with and without scoliosis. These characteristics were used to determine scoliosis risk factors. Results: In total, 331 adults fulfilled the inclusion criteria: 221 had open and 110 had closed SB. Of these, 176 (53%) had scoliosis: 57% open and 45% closed SB. As compared with individuals without scoliosis, those with scoliosis more frequently had open SB (p=0.03), more cranially located SB (p

Abstract

Background and Purpose: Additional therapy may improve poststroke outcomes. Self-rehabilitation is a useful means to increase rehabilitation time. Mechanized systems are usual means to extend time for motor training. The primary aim was to compare the effects of self-rehabilitation using a mechanized device with control self-exercises on upper extremity impairment in patients with stroke. Methods: Phase III, parallel, concealed allocation, randomized controlled, multicenter trial, with 12-month follow-up. Patients aged 18 to 80 years, 3 weeks to 3 months poststroke with a Fugl-Meyer Assessment score of 10 to 40 points, were randomized to the Exo or control groups. All undertook two 30-minute self-rehabilitation sessions/day, 5 days/wk for 4 weeks in addition to usual rehabilitation. The Exo group performed games-based exercises using a gravity-supported mechanical exoskeleton (Armeo Spring). The control group performed stretching plus basic active exercises. Primary outcome was change in upper extremity Fugl-Meyer Assessment score at 4 weeks. Results: Two hundred fifteen participants were randomly allocated to the Exo group (107) or the control group (108). Mean age (SD), 58.3 (13.6) years; mean time poststroke, 54.8 (22.1) days; and mean baseline Fugl-Meyer Assessment score, 26.1 (9.5). There was no between-group difference in mean change in Fugl-Meyer Assessment score following the intervention: 13.3 (9.0) in the Exo group and 11.8 (8.8) in the control group ( P =0.22). There were no significant between-group differences in changes for any of the other outcomes at any time point (except for perception of the self-rehabilitation). There was no between-group difference in cost utility at 12 months. Conclusions: In patients with moderate-to-severe impairment in the subacute phase of stroke, the purchase and use of complex devices to provide additional upper limb training may not be necessary: simply educating patients to regularly move and stretch their limbs appears sufficient.

Abstract

Background Illusion of movement induced by tendon vibration is commonly used in rehabilitation and seems valuable for motor rehabilitation after stroke, by playing a role in cerebral plasticity. The aim was to study if congruent visual cues using Virtual Reality (VR) could enhance the illusion of movement induced by tendon vibration of the wrist among participants with stroke. Methods We included 20 chronic stroke participants. They experienced tendon vibration of their wrist (100 Hz, 30 times) inducing illusion of movement. Three VR visual conditions were added to the vibration: a congruent moving virtual hand (Moving condition); a static virtual hand (Static condition); or no virtual hand at all (Hidden condition). The participants evaluated for each visual condition the intensity of the illusory movement using a Likert scale, the sensation of wrist’s movement using a degree scale and they answered a questionnaire about their preferred condition. Results The Moving condition was significantly superior to the Hidden condition and to the Static condition in terms of illusion of movement (p Conclusions This study showed the interest of using congruent cues in VR in order to enhance the consistency of the illusion of movement induced by tendon vibration among participants after stroke, regardless of their clinical severity. By stimulating the brain motor areas, this visuo-proprioceptive feedback could be an interesting tool in motor rehabilitation.

Abstract

International audience; Aims - To assess the relative risks of pelvic organ prolapse (POP) and urinary complications in adult spina bifida patients with neurogenic acontractile detrusor voiding with Valsalva versus those using clean-intermittent catheterization (CIC). Methods - We conducted a retrospective analysis including all spina bifida patients with neurogenic acontractile detrusor with a minimum follow-up of 12 months. Patients were then divided in two groups according to their bladder management: voiding with Valsalva versus CIC. The primary endpoint was any de novo or worsened rectal and/or pelvic organ prolapse (POP) diagnosed during follow-up. The secondary outcome was urinary complications defined as febrile urinary tract infections (UTI) and/or urolithiasis and/or renal failure. Results - Fifty-five patients (50.9% were males) met the inclusion/exclusion criteria: 28 voiding with Valsalva and 27 performing CIC. At baseline, the rates of vaginal prolapse (44.4% vs 50%; P = 0.99), and rectal prolapse/intussusception (25.9% vs 21.4%; P = 0.76) were similar in both groups. After a median follow-up of 80.6 and 65.6 months, respectively (P = 0.29), the rate of de novo or worsened rectal prolapse/intussusception was higher in the Valsalva voiding group than in the CIC group (32.1% vs 3.7%; P = 0.01). De novo or worsened vaginal prolapses were also more common in the Valsalva voiding group, but it did not reach statistical significance (33.3% vs 11.1%; P = 0.29). Conclusions - Valsalva voiding might be harmful in adult spina bifida patients with neurogenic acontractile detrusor as it may increase the risk of rectal prolapse/intussusception. Overall, the prevalence of POP and rectal prolapse was high in both groups.

Abstract

Introduction Motor Imagery (MI) is a powerful tool to stimulate sensorimotor brain areas and is currently used in motor rehabilitation after a stroke. The aim of our study was to evaluate whether an illusion of movement induced by visuo-proprioceptive immersion (VPI) including tendon vibration (TV) and Virtual moving hand (VR) combined with MI tasks could be more efficient than VPI alone or MI alone on cortical excitability assessed using Electroencephalography (EEG). Methods We recorded EEG signals in 20 healthy participants in 3 different conditions: MI tasks involving their non-dominant wrist (MI condition); VPI condition; and VPI with MI tasks (combined condition). Each condition lasted 3 minutes, and was repeated 3 times in randomized order. Our main judgment criterion was the Event-Related De-synchronization (ERD) threshold in sensori-motor areas in each condition in the brain motor area. Results The combined condition induced a greater change in the ERD percentage than the MI condition alone, but no significant difference was found between the combined and the VPI condition (p = 0.07) and between the VPI and MI condition (p = 0.20). Conclusion This study demonstrated the interest of using a visuo-proprioceptive immersion with MI rather than MI alone in order to increase excitability in motor areas of the brain. Further studies could test this hypothesis among patients with stroke to provide new perspectives for motor rehabilitation in this population.

Abstract

International audience; Unilateral cerebral palsy (uCP) causes upper limb movement disorders that impact on daily activities, especially in bimanual condition. However, a few studies have proposed bimanual tasks for 3D motion analysis. The aim of this study was to validate the new version of a child-friendly, 3D, bimanual protocol for the measurement of joint angles and movement quality variables. Twenty children with uCP and 20 typically developing children (TDC) performed the five-task protocol integrated into a game scenario. Each task specifically targeted one or two upper limb degrees of freedom. Joint angles, smoothness and trajectory straightness were calculated. Elbow extension, supination, wrist extension and adduction amplitudes were reduced; hand trajectories were less smooth and straight in children with uCP compared to TDC. Correlations between the performance-based score and kinematic variables were strong. High within and between-session reliability was found for most joint angle variables and lower reliability was found for smoothness and straightness in most tasks. The results therefore demonstrated the validity and reliability of the new protocol for the objective assessment of bimanual function in children with uCP. The evaluation of both joint angles and movement quality variables should increase understanding of pathological movement patterns and help clinicians to optimize treatment. ClinicalTrials.gov identifier: NCT03888443.

Abstract

The "Be an Airplane Pilot" (BE-API) protocol is a novel 3-D movement analysis (3DMA) protocol assessing the bimanual performance of children during a game.This study aimed to investigate the reliability and validity of this protocol in children with unilateral cerebral palsy (uCP).Angular waveforms (WAVE), maximum angles (MAX) and range of motion (ROM) of the trunk, shoulder, elbow and wrist joints were collected in children with uCP and in typically developing children (TDC) during 4 tasks of the BE-API protocol designed to explore specific degrees of freedom (DoF). The inter-trial reliability for children with uCP was assessed with the coefficient of multiple correlation (CMC) for WAVE and the intraclass correlation coefficient (ICC) and standard error of measurement (SEM) for MAX and ROM. Clinical performance-based measures, including the Assisting Hand Assessment (AHA) and ABILHAND-Kids scores, were used to explore correlations between clinical measures and kinematic parameters in children with uCP.20 children with uCP (13 boys; mean age 12.0 [SD 3.2] years) and 20 TDC (11 boys; mean age 11.9 [SD 3.4] years) were included. In children with uCP, most kinematic parameters showed high reliability (WAVE: CMC≥0.82; MAX and ROM: ICC≥0.85, SEM≤4.7°). Elbow extension, forearm supination, and wrist adduction were reduced and wrist flexion was increased for children with uCP versus TDC (P0.01). In children with uCP, MAX and ROM values were moderately correlated with clinical assessments (AHA score: r=0.48-0.65; ABILHAND-Kids score: r=0.48-0.49).The BE-API protocol is a 3DMA-bimanual performance-based assessment that is highly reliable in children with uCP. Children with uCP and TDC significantly differed in some clinically relevant kinematic parameters. The BE-API is a promising playful tool, helpful for better understanding upper-limb motor movement abnormalities in bimanual conditions and for tailoring treatments to individual deficits.

Abstract

International audience; Background. - Neck muscle vibration (NMV) is increasingly used for its modulation of body orientation and spatial perception, but its mechanisms of action are still not well known. Objectives. - To describe the effects of NMV on postural orientation and spatial perception, in both healthy people and patients with disturbed balance potentially related to distorted body orientation perception. Methods. - Following the PRISMA guidelines, a systematic search was performed using the databases MEDLINE, EMBASE, Cochrane library and PEDrO with the key words ((Postural balance) OR (Spatial reference)) AND (Neck muscle vibration) for articles published through to July 2016. Results. - A total of 67 articles were assessed; these exhibited wide heterogeneity and generally poor quality methodology. In healthy subjects, under bilateral NMV, the body tilts in the anterior direction (Level of Evidence LoE II). Under unilateral NMV, the visual environment moves towards the side opposite the vibration (LoE II) and the subject's experience of "straight ahead" is shifted towards the side of the vibration (LoE II). NMV also modulates both spatial and postural bias between stroke and vestibular patients. Discussion. - NMV modulates both spatial and postural bias and could thus be proposed as a tool in rehabilitative therapy. However, due to the heterogeneity of published data and the various significant shortfalls highlighted, current research does not allow clear guidelines to be proposed. (C) 2019 Elsevier Masson SAS.

Abstract

International audience; Objective. - We aimed to test a repeated program of vibration sessions of the neck muscles (rNMV) on postural disturbances and spatial perception in patients with right (RBD) versus left (LBD) vascular brain damage. Methods. -Thirty-two chronic stroke patients (mean age 60.9 +/- 10 yrs and mean time since stroke 4.9 +/- 4 yrs), 16 RBD and 16 LBD, underwent a program of 10 sessions of NMV over two weeks. Posturography parameters (weight-bearing asymmetry (WBA), Xm, Ym, and surface), balance rating (Berg Balance Scale (BBS), Timed Up and Go (TUG)), space representation (subjective straight ahead (SSA), longitudinal body axis (LBA), subjective visual vertical (SW)), and post-stroke deficiencies (motricity index, sensitivity, and spasticity) were tested and the data analyzed by ANOVA or a linear rank-based model, depending on whether the data were normally distributed, with lesion side and time factor (D-15, D0, D15, D21, D45). Results. -The ANOVA revealed a significant interaction between lesion side and time for WBA (P< 0.0001) with a significant shift towards the paretic lower limb in the RBD patients only (P=0.0001), whereas there was no effect in the LBD patients (P=0.98). Neither group showed a significant modification of spatial representation. Nonetheless, there was a significant improvement in motricity (P=0.02), TUG (P=0.0005), and BBS (P< 0.0001) in both groups at the end of treatment and afterwards. Conclusions. - rNMV appeared to correct WBA in RBD patients only. This suggests that rNMV could be effective in treating sustainable imbalance due to spatial cognition disorders.

Abstract

Background Adjunct therapies (ATs) may further improve outcomes after botulinum toxin injections in spastic patients, but evidence was unclear in previous systematic reviews. Objective To assess the efficacy of non-pharmacological ATs in spastic adults according to the International Classification of Functioning, Disability and Health and build an expert consensus-based on a Delphi process. Methods Four electronic databases were searched up to May 2020 for reports of comparative trials of non-pharmacologic ATs after botulinum toxin injections in spastic adults. Then, 25 French experts participated in a two-round Delphi process to build recommendations on the use of ATs. Results We included 32 studies (1202 participants, median 32/study) evaluating the effects of physical agents (n = 9), joint posture procedures (JPPs, n = 11), and active ATs (n = 14), mainly after stroke. The average quality of articles was good for randomised controlled trials (median [interquartile range] PEDro score = 7 [6–8]) but moderate (n = 2) or poor (n = 2) for non-randomised controlled trials (Downs & Black checklist). Meta-analysis was precluded owing to the heterogeneity of ATs, control groups and outcome measures. There is evidence for the use of JPPs except low-dose manual stretching and soft posture techniques. Continuous postures (by taping or casting) are recommended; discontinuous postures (by orthosis) may be preferred in patients with active function. Device-free or device-assisted active ATs may be beneficial in the mid-term (> 3 months after botulinum toxin injections), particularly when performed at a high-intensity (> 3 h/week) as in constraint-induced movement therapy. Self-rehabilitation remains understudied after a focal treatment, but its interest is highlighted by the experts. The use of physical agents is not recommended. Conclusions JPPs and active ATs (device-assisted or device-free) may further improve impairments and activities after botulinum toxin injections. Further studies are needed to better define the best strategies for ATs as a function of the individual treatment goals, participation and quality of life.

Abstract

Objective To evaluate recurrence and early postoperative complications (sepsis) following surgical excision combined with radiotherapy for troublesome hip heterotopic ossification in patients with spinal cord injury and traumatic brain injury. Design Retrospective case-control study. Setting Data relating to patients with spinal cord injury or traumatic brain injury who underwent surgical excision of hip heterotopic ossification were retrieved from the BANKHO database. Case patients underwent excision + radiotherapy and controls underwent excision only. Control patients were matched to case patients according to sex and age (± 4 years). Participants Data from 19 case patients and 76 controls were analysed. Interventions Not applicable. Main outcome measure The primary end-point was recurrence of heterotopic ossification. Secondary end-points were postoperative complications and, more specifically, sepsis that required surgical revision. Results There was no difference between the odds ratios (OR) for recurrence for each group (OR case group = 0.63, OR spinal cord injury subgroup = 0.45 and OR head injury subgroup = 1.04). The rate of sepsis requiring surgical revision was significantly higher in the case group (p Conclusion Based on the results of this case-control study, we suggest that radiotherapy should not be combined with surgery in patients with troublesome hip heterotopic ossification undergoing excision. Radiotherapy does not appear to prevent recurrence and, moreover, it is associated with an increased risk of postoperative sepsis.

Abstract

Stroke is a complex motor disease that not only affects perilesional areas but also global brain networks in both hemispheres. Neurofeedback (NF) is a promising technique to enhance neural plasticity and support functional improvement after stroke by means of brain self-regulation. Most of the studies using NF or brain computer interfaces for stroke rehabilitation have assessed treatment effects focusing on motor outcomes and successful activation of targeted cortical regions. However, given the crucial role of large-scale networks reorganization for stroke recovery, it is now believed that assessment of brain connectivity is central to predict treatment response and to individualize rehabilitation therapies. In this study, we assessed the impact of EEG-fMRI NF training on connectivity strength and direction using a Dynamic Causal Modeling approach. We considered a motor network including both ipsilesional and contralesional premotor, supplementary and primary motor areas. Our results in nine chronic stroke patients indicate that NF upregulation of targeted areas (ipsilesional SMA and M1) not only modulated activation patterns, but also had a more widespread impact on fMRI bilateral motor networks. In particular, inter-hemispheric connectivity between premotor and primary motor regions decreased, and ipsilesional self-inhibitory connections were reduced in strength, indicating an increase in activation during the NF motor task. To the best of our knowledge, this is the first work that investigates fMRI connectivity changes elicited by training of localized motor targets in stroke. Our results open new perspectives in the understanding of large-scale effects of NF training and the design of more effective NF strategies, based on the pathophysiology underlying stroke-induced deficits.

Abstract

International audience; BACKGROUND:Findings regarding the impact of language bias on treatment effect estimates (TEE) are conflicting, and very few studies have assessed these impacts in rehabilitation. The purpose was to compare TEE between studies published in non-English language (SPNEL) and those published in English language (SPEL) included in a previously published meta-analysis assessing the effects of physical therapy on balance and postural control after stroke.METHODS:Six databases were searched until January 2019. Two independent reviewers selected randomised trials, extracted data, and assessed risk of bias. We conducted subgroup meta-analyses according to the language of study publication, then compared TEE between SPEL and SPNEL subgroups by using a random-effects meta-regression model.RESULTS:From 13,123 records, 132 SPEL (n = 5219) and 13 SPNEL (n = 693) were included. SPNEL had a weight in the pooled estimate (8.2%) significantly lower than SPEL (91.8%; p

Abstract

International audience; Illusion of movement induced by tendon vibration is a powerful approach to improve cortical excitability and can be useful for rehabilitation of neurological impairments. The aim of our study was to investigate whether a visual feedback of a moving hand congruent to the proprioceptive illusion induced by a tendon vibration of the wrist could increase the illusion of movement.

Abstract

Resume Introduction En neuro-urologie pediatrique, la mise en place des sondages intermittents puis l’apprentissage des auto-sondages sont des etapes importantes pour les enfants presentant une vessie neurologique. Il n’existe pas d’echelle d’evaluation specifique de l’enfant de l’adherence et de la satisfaction aux sondages (auto- ou hetero-). L’objectif de cet article est d’etudier la faisabilite de l’InCaSaQ (Intermittent Catheterization Satisfaction Questionnaire) et de l’ICAS (Intermittent Catheterization Adherence Scale) chez l’enfant, et d’en realiser les premieres etapes de validation. Materiel et methodes Etude monocentrique de validation d’echelle. Les criteres d’inclusion etaient la presence chez les patients d’une vessie neurologique, la realisation reguliere de sondages intermittents (auto- ou hetero-) et un âge inferieur a 18 ans. Les questionnaires InCaSaQ et ICAS etaient envoyes a deux reprises entre mars et avril 2017, puis remplis par l’enfant ou ses parents selon qui effectuait les sondages. La consistance interne (alpha de Cronbach) mesurait la validite de construit. La reproductibilite etait mesuree par le cœfficient de correlation (CCI) et les tests de Wilcoxon et de McNemar. La pertinence et la facilite de remplissage etaient evaluees pour chaque score (evaluation sur une echelle de 0 a 10 par la personne remplissant le questionnaire). Resultats Vingt deux patients ont ete inclus, et 50 questionnaires ont ete recuperes (25 ICAS et 25 InCaSaQ), a deux reprises. La consistance interne est satisfaisante pour InCaSaQ (alpha de Cronbach > 0,7) et la reproductibilite est bonne pour les deux questionnaires (CCI > 0,7 pour la majorite des items). Les patients sous auto-sondages avaient une moins bonne adherence que les parents realisant des hetero-sondages (ICAS a 3,25 contre 0,70 chez les enfants sous hetero-sondages). L’item le plus abaisse dans l’InCaSaQ etait la maniere de se debarrasser de la sonde. Conclusions L’InCaSaQ et l’ICAS sont des outils qui peuvent etre utilises chez l’enfant sous auto-sondages ou hetero-sondages. Des etudes de plus grande ampleur seront necessaires pour en finaliser la validation. Niveau de preuve 4.

Abstract

Resume Objectif Le traitement par neurostimulation tibiale posterieure transcutanee (NTPT) a montre son efficacite dans le traitement de l’hyperactivite vesicale (HAV), mais son effet chez les patients diabetiques est mal connu. Le but de cette etude etait de comparer l’efficacite du traitement par NTPT chez les patients diabetiques ayant une HAV et chez les patients ayant une HAV sans diabete. Methodes Une etude prospective monocentrique incluait tous les patients traites par NTPT pour troubles vesico-sphincteriens entre 2012 et 2016. Le critere de jugement principal etait l’efficacite ≥ 50 % de la symptomatologie evaluee au moyen d’une echelle visuelle analogique (EVA) a deux mois. Le traitement instaure consistait en une seance de NTPT quotidienne de 20 min. Les criteres de jugement secondaires etaient les donnees du calendrier mictionnel, l’Urinary Symptom Profile (score d’hyperactivite vesicale), le retentissement sur le moral et sur les activites de la vie quotidienne evalues par EVA. Resultats Soixante et onze patients ont ete inclus, dont 10 etaient diabetiques. Le taux d’efficacite (EVA ≥ 50 %) n’etait pas significativement different dans le groupe des patients diabetiques (70 % vs. 44,1 % dans le groupe non diabetique ; p = 0,17), de meme que l’EVA efficacite moyenne (4/10 vs. 4/10 ; p = 0,98). Le sous-score USP HAV diminuait significativement dans les deux groupes a 2 mois (−3 points dans le groupe diabetique ; −1,9 points dans le groupe non diabetique ; p = 0,03 et p Conclusion Les resultats fonctionnels de la NTPT semblent similaires dans le traitement de l’HAV chez les patients diabetiques et chez les patients non diabetiques.

Abstract

Introduction L’asymetrie posturale et l’augmentation des oscillations sont des caracteristiques frequentes retrouvees sur plateforme de force apres AVC. L’asymetrie persiste au long cours et son origine ainsi que son impact sur l’equilibre sont discutes. En dehors de la faiblesse musculaire, la diminution de la sensibilite ou la spasticite, les troubles de la representation de l’espace en est probablement au moins en partie responsable. La correction de l’asymetrie posturale est integree depuis longtemps dans les programmes de reeducation classique de maniere top down. Mais la correction de l’asymetrie posturale peut egalement etre obtenue par stimulation sensorielle (proprioception, vestibulaire, visuelle). Il s’agit alors d’une correction de type bottom up qui est interessante surtout chez des patients cerebraux leses droits qui ont souvent des troubles attentionnels est une anosognosie. Un ensemble assez consequent d’etudes ont ete realises sur l’effet instantane d’une seance de stimulation sensorielle. Methodes/Resultats Nous avons teste des stimulations repetees par vibration des muscles du cou sur une petite population de 32 AVC a plus de six mois qui a montre que les AVC droits qui etait initialement plus devies retrouvaient une asymetrie comparable a celle des AVC droit. Plus recemment nous avons mene une etude multicentrique randomisees controlees sur 85 AVC droits avec 4 bras (adaptation prismatique/vibration/prisme + vibration/controle) dont les resultats sont en cours d’interpretation. Conclusion La modulation de l’asymetrie posturale apres AVC par les stimulations sensorielles represente une nouvelle voie de traitement interessante et facile a mettre en œuvre.

Abstract

Introduction La contemplation et la perception d’une œuvre d’art au complet implique le regard et l’orientation de la tete. Cette derniere depend des informations proprioceptives du cou. L’application des vibrations sur les muscles du cou stimulent ces informations, et peut generer des reponses posturales. Nous voulons determiner si l’application de vibrations nucales modifie l’exploration visuelle d’une œuvre d’art, et comment la tâche d’exploration affecte les reponses posturales aux vibrations. Materiel et methode Vingt adultes en bonne sante porteront un systeme de suivi du regard (Tobii) et l’application App Balance de mesure de l’equilibre. En position debout, ils exploreront trois tableaux (largeur > 1 m) et identifieront 7 details. L’exploration se fera sans ou avec vibrations nucales (gauches et droites) (VB115, TechnoConcept) de maniere randomisee. Un test d’exploration visuelle de type papier-crayon (test des cloches) sera egalement effectue en position assise. Analyse Les tableau seront divises en 7 colonnes ; la 1re colonne exploree, les temps de fixation et le nombre de visite sur chaque colonne, ainsi que l’activite posturale seront compares entre les differentes conditions. Resultats attendus L’application de vibrations nucales modifiera l’exploration visuelle. Les reponses posturales aux vibrations seront attenuees lors de l’exploration, du fait du meilleur ancrage visuel fourni par l’exploration. Discussion Les personnes avec des deficits de la perception visuelle pourraient beneficier de ce type d’intervention, en situation ecologique. Les donnees des sujets en bonne sante aideront a interpreter les resultats de ces patients recrutes dans une future etude.

Abstract

Objectifs L’objectif de cette etude etait de comparer les resultats de la cystectomie par voie ouverte (CO), par voie laparoscopique pure (CL) et par voie robot-assistee (CRA) associee a une derivation cutanee non continente trans-ileale chez les sujets neurologiques. Methodes Tous les patients ayant eu une cystectomie pour vessie neurologique dans un centre entre 2006 et 2017 ont ete inclus dans une etude retrospective. La derivation etait une derivation cutanee trans-ileale non continente type Bricker dans 100 % des cas dans les 3 groupes, toujours realises en extra-corporel. La plupart des CO et CL etaient realisees par un chirurgien experimente (> 20 cystectomies au debut de l’etude et > 50 procedures laparoscopiques) et la plupart des CRA par un autre chirurgien sans aucune experience de la cystectomie et ayant realise moins de 10 interventions laparoscopiques ou robot-assistees en autonomie au debut de l’etude. Resultats Quatre-vingt-dix patients ont ete inclus : 41 robot, 23 cœlioscopique et 26 ouvert ( Tableau 1 ). La duree operatoire etait plus courte dans le groupe CO que dans les groupes CL et CRA (295,6 vs. 383,7 vs. 374,4 min ; p = 0,03). La duree d’hospitalisation etait plus courte dans le groupe CRA et dans le groupe CL que dans le groupe CO (16,5 vs. 13,5 vs. 13,2 jours ; p = 0,03). Le taux de complications majeures etaient plus importants dans les groupe CO et CL que dans le groupe CRA (30,8 % vs. 30,4 % vs. 9,8 % ; p = 0,05) de meme que le taux d’utilisation d’une PCA morphine en postoperatoire (62,5 % vs. 77,8 % vs. 22,9 % ; p = 0,003). Le taux de complications tardives etait similaire dans les 3 groupes (13 % vs. 14,3 % vs. 21,9 % ; p = 0,60) ( Tableau 2 ). Conclusion La voie laparoscopique, qu’elle soit ou non robot-assistee, pourrait diminuer la duree d’hospitalisation par rapport a la voie ouverte pour l’exerese d’une vessie neurologique avec derivation cutanee non continente trans-ileale, au prix d’une duree operatoire plus longue. L’avantage de la voie robotique sur la voie cœlioscopique pourrait etre une reduction du taux de complications majeures et des douleurs postoperatoires.

Abstract

Motor nerve blocks with anesthetic drug for local anesthesia are commonly used in physical and rehabilitation medicine (PRM), especially in the field of spasticity. Guidelines in this context are currently lacking.Eighteen experts selected on the basis of their recognized experience by the scientific committees of the French PRM (SOFMER) and Anesthesia and Intensive care (SFAR) societies were invited to work and propose guidelines for the use of loco-regional anesthetic drug for motor nerve blocks in PRM setting. Eight issues were addressed: which neural blocks for which indications; drugs and contraindications; medical survey and attitude in case of adverse event; injection and guidance material; patient preparation and pain relief; efficacy assessment; patient information; education of PRM physiatrists. The Medline, Cochrane and Embase databases for the period 1999 to 2018 were consulted and 355 papers analyzed. The drafts were commented then approved by the whole group using electronic vote, before final approval by scientific committee of each society.No scientific evidence emerged from the literature. Thus, these guidelines are mainly based on the opinion of the expert panel. Guidelines for each issue are reported with the main points of arguments. The main question deals with the recommendation about doses for each drug: for lidocaine - up to 2mg/kg - "check contraindications, emergency truck available, no need of previous anesthetic consultation nor presence of anesthetic physician"; for ropivacaine - up to 1.5mg/kg, with a maximum of 100mg - the same but after intravenous line. Beyond these doses, SFAR guidelines have to be applied with the need of anesthetic physician.These are the first organizational guidelines devoted to increase the security of motor nerve block use in PRM settings.

Abstract

Objectifs La neurostimulation du nerf tibial posterieure transcutanee (NSTP) est devenue ces dernieres annees, pour les patients ayant une hyperactivite vesicale (HAV), une option therapeutique reconnue. Le but de cette etude etait de rapporter les resultats de la NSTP chez les patientes atteintes d’HAV. Methodes Les donnees cliniques des patientes ayant une HAV, traitees par NSTP ont ete collectees prospectivement entre 2013 et 2018 dans un centre universitaire. Le traitement etait auto-administre par les patientes, au domicile a l’aide du dispositif urostim 2. Les seances devaient durer 20 minutes, quotidiennement, sur une periode minimum de 3 mois. Une seance de formation initiale d’une heure avec une infirmiere dediee etait realisee. Le critere de jugement principal etait l’impression d’amelioration, evaluee par la patiente a 3 mois a l’aide d’une echelle visuelle analogique (EVA) allant de 0 a 10. Les criteres secondaires etaient les donnees du calendrier mictionnel et le questionnaire USP. Resultats Soixante-deux patientes ont ete incluses. La moyenne d’âge des patientes etait de 58,3 ans. Cinquante-trois patientes avaient une incontinence urinaire par urgenturie (85,5 %) et 9 avaient une HAV sans fuites (14,5 %). La plupart des patientes avaient une hyperactivite detrusorienne au bilan urodynamique (71,1 %) et la majorite etaient resistantes aux traitements anticholinergiques (67,7 %). La moyenne de l’EVA efficacite a 3 mois etait de 4,8 (± 3,5). Le score d’HAV de l’USP diminuait significativement de 11,1 (± 4,1) a 9 (± 4) a 12 semaines (p = 0,0006). La capacite vesicale fonctionnelle s’ameliorait significativement avec un volume urine passant de 309,2 (± 168,5) a 355 (± 213,3) mL (p = 0,02). Le nombre d’episodes d’incontinence urinaire quotidien diminuait significativement egalement passant de 4,9 a 3,4 (p = 0,002). Le taux d’arret du traitement a 3 mois etait de 46,9 %. Conclusion La NSTP transcutanee semble etre une option therapeutique efficace chez les patientes atteintes d’HAV. Des etudes complementaires sont necessaires pour evaluer l’efficacite, les effets secondaires et le cout-efficacite de ce traitement comparativement a la NSTP percutanee.

Abstract

International audience; Objective: To investigate the postural effect of 2 types of sensory stimulation in patients with a left hemispheric lesion (LHL) or right hemispheric lesion (RHL) compared with controls. Methods: 35 patients (18 LHL, 17 RHL) and 27 controls (Mean age 54.1 years), with a mean delay post-stroke of 3.0 months were enrolled. Subjects stood on a force platform and were stimulated on the left and right side by optokinetic (Okn) and galvanic vestibular (Gv) stimulation. Lateral displacement following stimulation towards the right and left directions was calculated as the mean position of the centre of pressure (CP) during the stimulation period minus the mean position at rest. Results Postural asymmetry was reduced in LHL and RHL patients. CP displacement was higher in cases of left-sided stimulation in the RHL group compared with control subjects and LHL patients (respectively 2.8 and 2.4 times higher, group effect, p

Abstract

Bonan M2S; International audience; Balance disorders related to disturbances in perception of spatial reference systems are common especially after right hemispheric stroke. Mental misrepresentation of bodily orientation in space is then often superimposed upon other factors affecting imbalance such as motor and sensory impairments. Traditional rehabilitation for balance recovery has not been specifically designed to improve balance disorders related to spatial cognition. The traditional approach, consisting of stimulating the conscious perception of body orientation in space, is demanding and laborious. The approach based on sensorial stimulation is completely different. The relevance of this method lies in the fact that, firstly it is specifically active in the cognitive component of balance disorders; and secondly, it can passively be applied with minimal patient participation, which is of particular importance for this patient group characterized by disorders of attention and concentration. These techniques, such as proprioceptive, visual or vestibular stimulation, have been found to correct spatial neglect but also postural bias. Clinical and data from functional neuro-imaging suggest a direct central action on cortical structures involved in the elaboration of spatial representation. These are promising techniques for the rehabilitation of postural disturbances related to spatial cognition disorders but are as yet at the stage of preliminary results

Abstract

Introduction Muscle vibrations can be used to induce a body tilt. Even though several muscle sites have been tested for various diseases their respective mode of action were not highlighted. The objective was to compare the effects of neck muscle vibrations (NMV) and gluteus medius vibrations (GMV) on posture in healthy subjects. Material and methods Thirty-one healthy subjects (23yr ± 2) were tested, closed eyes, in standing position on force platform with Optitrack 3D capture system. They received successively a 5 min-session of NMV and 5 min-session of GMV in a randomized order. They were evaluated during the vibration, immediately at the end of the vibration and 5 minutes after. Results GMV induced a Center of Pressure tilt to the opposite side of the vibration (−7.6 ± 2 mm P Discussion These results are in favor of a different mode of action between neck and gluteus medius vibrations.

Abstract

Introduction Postural asymmetry is a cause of disability for subjects after a stroke and generally assessed with the force platform (FP). The objectives were to map out the characteristics of assessing postural asymmetry; thereafter to synthesize on how postural asymmetry develops in time after a stroke and finally, to describe postural asymmetry and its relations. Material and methods Following the PRISMA guidelines, a systematic search was performed using the databases MEDLINE, EMBASE, Cochrane library and PEDrO with the key words (Weight-Bearing Asymmetry OR Center of Pressure) AND (Stroke) for articles published through to November 2017. Results One hundred and ninety-five articles were included and highlighted certain heterogeneity in the manner in which the evolution was performed. As expected postural asymmetry was found at an acute stage and still persistent at a chronic stage with a possible difference between left and right brain damage. Thirty-two articles were included in the meta-analysis, which revealed an important number of correlations (124) carried out with postural asymmetry with heterogeneity in the results. Discussion The variability and the heterogeneity in the measurement method as well as the important number of correlations carried out with postural asymmetry does not allow us to draw a reasonable conclusion from the information presented and furthers studies are needed.
