Using virtual reality (VR) for Muscular Dystrophy (MD) rehabilitation promises to be a novel therapeutic approach, potentially enhancing motor learning, functional outcomes, and overall quality of life. This systematic review primarily aimed to provide a comprehensive summary of the current understanding regarding the application of VR in supporting MD rehabilitation. A systematic search was performed in PubMed, Scopus, Cochrane Library, and Web of Science to identify relevant articles. The inclusion criteria encompassed studies involving individuals diagnosed with MD who underwent VR interventions, with a primary focus on assessing functional improvement. Methodological quality of the studies was assessed by using the Physiotherapy Evidence Database (PEDro) scale. Seven studies, involving 440 individuals with Duchenne Muscular Dystrophy (DMD), were included in the review. Among these studies, six primarily explored the motor learning potential of VR, while one study investigated the impact of VR training on functional abilities. In conclusion, the qualitative synthesis supports VR-based interventions' potential positive effects on motor learning, performance improvement, and functional outcomes in individuals with DMD. However, current usage mainly focuses on assessing the potential mechanisms' benefits, suggesting the importance of expanding clinical adoption to harness their therapeutic potential for MD patients.

Objective: This research aimed to determine the efficacy of VR therapy in mitigating symptoms of depression, anxiety, and stress among older adults following arthroplasty surgery and to comprehend the influence of psychological improvement on changes in functional outcomes. Methods: Utilizing a parallel-group randomized controlled trial design, the study involved 68 osteoarthritis patients who had recently undergone either total hip or knee arthroplasty. Subjects were split into two groups. The experimental group underwent eight VR therapy sessions during their rehabilitation, while the control group was given standard care. Assessments encompassed both psychological and functional outcomes, with tools like the Hospital Anxiety and Depression Scale, Perceived Stress Scale, and the Barthel Index, among others. The experimental group showcased notable enhancements in both psychological and functional areas compared to the control group. Results: A significant (p value of < 0.001) relationship was found between psychological progress and functional recovery, indicating that psychological factors can serve as predictors for functional outcomes. Conclusions: The findings emphasize the promising role of VR therapy as a beneficial addition to the rehabilitation process for older adults' post-hip and knee arthroplasty. The integration of psychological interventions in standard rehabilitation practices appears valuable, but further studies are needed to ascertain the long-term advantages of such an approach.

The study aimed to evaluate the effectiveness of virtual reality therapy (VRT) in the treatment of anxiety–depressive disorders and in reducing stress levels in a group of men with coronary heart disease (CHD) participating in cardiac rehabilitation (CR). The study included 34 men with CHD who were assigned to the experimental group (EG) or the control group (CG). CR in the EG was supported by 8 VRT sessions, while CR in the CG was supplemented with 8 SAT sessions. Anxiety–depressive disorders were assessed using the Hospital Anxiety and Depression Scale (HADS). Perceived stress was assessed using the Perception of Stress Questionnaire (PSQ). In the EG, all measured parameters improved after the intervention. Significant reductions in HADS total score, the HADS-A, general stress score, emotional tension, and the external stress were obtained. In the CG, a deterioration in all measured parameters was observed. Significant changes were obtained in the general stress score and intrapsychic stress. The analysis between groups showed that the effectiveness of psychological interventions significantly differed between groups. The study results confirmed that supplementing standard CR with VRT leads to an improvement in the mental state of the patients and thus has a positive effect on the course of CR. However, the small sample size and high withdrawal rate prompt cautious interpretation of the results. [ABSTRACT FROM AUTHOR]

This paper describes the influence of the presence of an obstacle near the flue pipe's mouth on the air jet, which directly affects the parameters of the sound generated by the flue pipe. Labial pipes of the most common types of mouth were tested. The method of interval calculus was used instead of invasive measuring instruments. The obtained results prove that the proximity of an obstacle affects the sound's fundamental frequency, as the airflow speed coming out of the flue pipe's mouth changes. The relationship between the airflow speed, the value of the Reynolds number, and the Strouhal number was also established. The thesis of the influence of the proximity of an obstacle on the fundamental frequency of the sound of a flue pipe was generalized, and formulas for calculating the untuning of the sound of the pipe were presented for various types of mouth.

The SARS-CoV-2 virus pandemic has forced far-reaching changes in higher education. Isolation from peers and distance learning have significantly limited interpersonal contacts, which might have affected the mental well-being of students. Therefore, the aim of the study was to investigate the prevalence of depressive symptoms and the level of perceived stress during e-learning among Slovak students and to identify the variables that have the most significant impact on mental health among students. The study included 3051 participants, 1773 women (58%) and 1278 (42%) with a mean age of 22.37 years. The Perceived Stress Scale (PSS-10) and Beck Depression Inventory (BDI-II) were used to measure the severity of stress and depression level. In addition, an author's survey was used assessing the areas of social life, education skills, economic field, nutrition habits, and drugs. Almost all study participants were characterized by increased stress level and 47% of them were depressed. Moreover, isolation affected women more, especially in terms of social life and economics. It seems necessary to implement appropriate support programs for students, which could have the potential to improve their psychological condition. [ABSTRACT FROM AUTHOR]

Needle-related procedures are often a source of pain, anxiety and fear in young patients. This systematic review aimed to investigate the effectiveness of virtual reality (VR) on reducing pain, fear and anxiety in pediatric patients undergoing needle-related procedures. Pain, anxiety, fear, changes in blood pressure and heart rate as well as satisfaction were evaluated as outcomes during needle-related procedures in VR compared with standard care conditions. A meta-analysis was performed, taking into account online databases. Two authors independently conducted literature searches in December 2020. The last search was conducted in March 2021 from a total of 106 records, 7 met our inclusion criteria. One study was excluded from the meta-analysis due to insufficient data. VR was applied as a distractor during venous access. Statistically significant benefits of using VR were shown in children's pain scores, where VR significantly decreased symptoms (n = 3204 patients, MD = −2.85; 95% CI −3.57, −2.14, for the Wong–Baker Faces Pain Rating Scale and n = 2240 patients, MD = −0.19; 95% CI −0.58, 0.20, for the Faces Pain Scale—Revised). The analysis of fear, anxiety and satisfaction scores revealed no significant differences between the conditions, as the studies were too heterogeneous to be pooled. Distraction using virtual reality may be an effective intervention for reducing pain in children undergoing needle-related medical procedures. However, further research in the implementation of VR as a distractor for children and adolescents is required, due to the limited research into this field. [ABSTRACT FROM AUTHOR]

The chest organ, which gained popularity at the beginning of the 17th century, is a small pipe organ the size of a large box. Several years ago, while compiling an inventory, a previously unidentified chest organ was discovered at St. John the Baptist's Co-Cathedral in Kamień Pomorski. Regrettably, the instrument did not possess any of its original pipes. What remained, however, was an image of the front pipes preserved on the chest door. The main issue involved in the reconstruction of a historic instrument is the restoration of its original tuning (temperament). Additionally, it is important to establish the frequency of A4, as this sound serves as a standard pitch reference in instrument tuning. The study presents a new method that aims to address the above-mentioned problems. To this end, techniques to search for the most probable temperament and establish the correct A4 frequency were developed. The solution is based on the modeling of sound generation in flue pipes, as well as statistical analysis to help match a model to the parameters preserved in the chest organ drawing. Additionally, differentalues of the A4 sound values were defined for temperatures ranging from 10 ∘ C to 20 ∘ C. The tuning system proposed in 1523 by Pietro Aaron proved to be the most probable temperament. In the process of testing the developed flue pipe model, the maximum tuning temperature was established as 15.8 ∘ C. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the impact of exercise training on the quality of life (QoL) of patients diagnosed with stage IIIB and stage IV non–small cell lung cancer (NSCLC) compared to a passive control group (CG). The exercise-trained group (ETG) consisted of 18 patients, and the CG consisted of 8 patients. The training program in the ETG consisted of two 2-week running cycles interspersed with consecutive rounds of chemotherapy with cytostatic drugs. A comparison of the changes in the Short Form (36) Health Survey (SF-36), St. George's Respiratory Questionnaire (SGRQ), and the Functional Assessment of Cancer Therapy-Lung (FACT-L) was the primary outcome. Analysis of the results of the SGRQ and the SF-36 questionnaire did not reveal any statistically significant differences in the assessment of QoL between the examined groups. The analysis of FACT-L questionnaires showed statistically significant changes, indicating deterioration of QoL in domains describing physical well-being in the CG. Therefore, the analysis of the results of the QoL assessment did not show any significant improvements in the group of patients undergoing comprehensive exercise training, although deterioration of QoL was noted in the CG.

Background and Objectives : The relationship between physical health and mental health has been considered for years. A number of studies have shown a correlation between depressive states and the progress of somatic diseases. It seems that the proper cooperation of specialists may result in the improvement of the patient's well-being and a positive effect on the course of the rehabilitation process. The aim of this study was to assess the symptoms of depression, anxiety, and stress in patients with chronic obstructive pulmonary disease (COPD) as well as the assessment of the relationship of psychological symptoms with sociodemographic factors and physical condition. Materials and Methods : The study enrolled 51 COPD patients who underwent a three-week pulmonary rehabilitation program. After admission to the rehabilitation department, the subjects were asked to complete the Hospital Anxiety and Depression Scale (HADS) questionnaire, the Perception of Stress Questionnaire (PSQ), and a sociodemographic questionnaire. Results : Anxiety states were diagnosed in 70% of respondents and depressive states were diagnosed in 54% of patients. Some of the respondents (14%) also showed a tendency to experience various grounded stresses. Additionally, there were correlations between the mental state and the results of fitness and respiratory tests. Conclusions : Patients with COPD are at risk for mental disorders, which may adversely affect their general health and significantly limit their physical and respiratory efficiencies. The development of widely available therapeutic solutions to reduce symptoms associated with depression, anxiety, and stress seems to be an important challenge for the management of patients with COPD.
