Effects of Video-Game Based Therapy on Balance, Postural Control, Functionality, and Quality of Life of Patients with Subacute Stroke: A Randomized Controlled Trial

The effectiveness of an exergame intervention for college students with subthreshold depression: protocol for a mixed methods study

Background

Subthreshold depression (StD) is a condition that significantly influences the mental health and quality of life of college students and increases the risk of developing major depressive disorder (MDD). Exercise therapy has been found to be effective, but may not be enjoyable for everyone. exergames, as a form of exercise therapy, address the limitations of traditional exercise by incorporating gaming elements to make physical activity more entertaining and interactive. Currently, the Nintendo Switch is one of the most widely used exergame devices.

Aims

To explore the effectiveness of a Nintendo Switch-based exergame intervention on college students with StD compared to a control group, and to analyze their perceptions of the program.

Methods

This study will employ an explanatory sequential design, starting with a quantitative evaluation using a randomized controlled trial (RCT), followed by a supplementary qualitative study. College students identified as having StD will be randomly allocated in a 1:1 ratio into the exergame intervention group (EIG) or the control group (CG). College students in the EIG will participate in a Nintendo Switch-based exergame program for 8 weeks, with 2-3 sessions per week, lasting 50-60 min each. Participant outcomes in both conditions will be assessed at pre-intervention (T0, week 0), post-intervention (T1, week 8), 1 month after the intervention (T2, week 12), and 2 months after the intervention (T3, week 16), and a generalized linear mixed model will be used for analysis. In the qualitative part of this study, interviews will be conducted with college students with StD from the EIG at T1 to explore their experiences of receiving the intervention, and content analysis will be applied to the data collected.

Discussion

Nintendo provides a user-friendly platform for college students with StD to engage in electronic gaming. Limited research has explored the mental health outcomes of interventions using this type of technology in young people with StD. If the exergame program proves to be effective, it could offer a convenient and feasible intervention for further enhancing the psychological well-being of college students.

Effects of kinect-based virtual reality training on bone mineral density and fracture risk in postmenopausal women with osteopenia: a randomized controlled trial

Osteopenia is a condition characterized by low bone mineral density (BMD) that increases fracture risk, particularly among postmenopausal women (PMW). This study aimed to determine the effects of Kinect-based VRT on BMD and fracture risk in PMW with osteopenia. The study was a prospective, two-arm, parallel-design, randomized controlled trial. The study enrolled 52 participants, 26 randomly assigned to each group. In the experimental group, Kinect-based VRT was provided thrice weekly for 24 weeks for 45 min/session. Both groups were instructed to engage in a daily 30-min walk outdoors. The fracture risk assessment tool (FRAX) was used to calculate fracture risk, and dual-energy X-ray absorptiometry was used to measure lumbar spine and femur neck BMD. Both variables were assessed at baseline and 24 weeks afterwards. After 24 weeks of Kinect-based VRT, the experimental group showed significant BMD increases in the right and left femoral necks and lumbar spine (p value < 0.001). In the control group, the BMD at the right and left femoral necks showed fewer significant changes (p value < 0.022 and 0.004, respectively). In the control group, lumbar spine BMD did not change (p = 0.57). The experimental group showed significantly lower FRAX scores for hip fracture prediction (HFP) and hip prediction of major osteoporotic (HPMO) at both femoral necks (p value < 0.001) than the control group (p = 0.05 and p = 0.01, respectively), but no significant change at the left femoral neck for HFP (p = 0.66) or HPMO (p = 0.26). These findings indicate that a Kinect-based VRT intervention resulted in significantly increased BMD and a reduced fracture risk, as predicted by HFP and HPMO measurements. These improvements were more pronounced in the experimental group than in the control group. Thus, Kinect-based VRT may be utilized as an effective intervention to improve BMD and reduce fracture risk in postmenopausal women with osteopenia.

Wii Fit-Based Biofeedback Rehabilitation Among Post-Stroke Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trial

BACKGROUND

Stroke is one of the most widespread reasons for acquired adult disability. Recent experimental studies have reported the beneficial influence of Wii Fit-based feedback on improving overall balance and gait for stroke survivors.

METHODS

We conducted a systematic review of the literature using the following keywords to retrieve the data: feedback, biofeedback, stroke, visual, auditory, tactile, virtual reality, videogame rehabilitation, Nintendo Wii stroke, videogame stroke, exergame stroke, Nintendo Wii rehabilitation, balance, and gait. A review and meta-analysis of RCTs regarding Wii Fit-based rehabilitation accompanied by conventional therapy effects on Berg Balance Scale (BBS), Timed Up and Go (TUG), functional reach test, and gait (speed) in stroke survivors was conducted.

OBJECTIVE

To determine the impacts of Wii Fit-based feedback combined with traditional therapy on balance and gait in stroke survivors.

RESULTS

22 studies were included. The meta-analysis results revealed statistically significant improvements in functional ambulation measured using TUG (p < 0.0001), balance measured using BBS (p = 0.0001), and functional reach test (p = 0.01), but not in gait speed (p = 0.32) following Wii Fit-based feedback. Regarding the types of feedback, significant differences were found in BBS scores when mixed visual and auditory feedback was used.

CONCLUSION

Wii Fit-based feedback has desired effects on improving balance in stroke patients, making it a suitable adjunct to physical therapy.

Effect of web-implemented exercise interventions on depression and anxiety in patients with neurological disorders: a systematic review and meta-analysis

Introduction

Web-implemented exercise intervention is the latest and innovative method to improve people's mental health. Currently, many studies have proven that web-implemented interventions are effective to improve depression and anxiety in adults. However, the influence of different web-implemented exercise interventions on depression and anxiety in patients with neurological disorders is still unclear.

Objective

The study aims to systematically summarize the type and content of web-implemented exercise interventions and quantify the effect of different web-implemented exercise interventions on depression and anxiety in patients with neurological disorders.

Methods

Four literature databases (PubMed, Web of Science, China National Knowledge Infrastructure, and WanFang data) were searched. The literature search considered studies published in English or Chinese before October 13, 2022. Randomized controlled trials (RCTs) that participants accepted web-implemented interventions were included. Two authors independently extracted data and assessed the risk of bias for included studies. Standardized mean differences (SMD) with 95% CI were used to integrate the effect size.

Results

16 RCTs (a total of 963 participants) were included. The results showed that web-implemented exercise intervention had a significant effect on depression (SMD = -0.80; 95% CI, -1.09 to -0.52; I2 = 75%; P < 0.00001) and anxiety (SMD = -0.80; 95% CI, -1.23 to -0.36; I2 = 75%; P = 0.0003) in patients with a neurological disorder. The subgroup analysis showed that the effectiveness of the web-implemented exercise intervention was influenced by several factors, such as web-implemented exercise intervention type, component, and intervention duration.

Conclusion

Web-implemented exercise intervention has a relieving effect on depression and anxiety symptoms in patients with neurological disorders. Additionally, the intervention type, intervention duration, and component can influence the effect size.

The effectiveness of virtual reality games in improving cognition, mobility, and emotion in elderly post-stroke patients: a systematic review and meta-analysis

This review is aimed to assess the effectiveness of virtual reality (VR) games on cognition, mobility, and emotion in elderly stroke patients. We selected relevant articles from eight databases from 2011 to 2022 and extracted articles on cognitive ability (general cognition, mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) et al.), mobility (modified Barthel index (MBI), Fugl-Meyer assessment (FMA), Berg balance scale (BBS), functional independence measure motor (FIM MOT)), and emotion (depression/anxiety). Twenty-nine studies including 1311 participants were included in the analysis. In the results, virtual reality games were more effective in improving overall cognitive function in stroke patients compared to conventional therapies. In addition, the intervention group in the MMSE (SMD = 0.6, 95%CI = 0.26-0.95, P = 0.0007), MoCA (MD = 1.97, 95%CI = 1.3-2.64, P < 0.00001), and attention test (MD = 0.25, 95% CI = 0.01-0.49, P < 0.00001) scores were also higher. In terms of physical function, MBI (SMD = 0.61, 95%CI = 0.14-1.08, P = 0.01), FMA (SMD = 0.47, 95%CI = 0.02-0.93, P = 0.04), BBS (SMD = 0.78, 95%CI = 0.42-1.15, P < 0.0001), and FIM MOT (MD = 5.87, 95%CI = 2.57-9.17, P = 0.0005) indicators showed better results. It is also observed that virtual reality games can effectively relieve depression and improve mental health in stroke patients. Sports game training, especially with VR equipment, had a positive impact on improving the cognitive performance, mobility, and emotional state of stroke patients compared to a control group. Although the improvement in cognitive ability is relatively low, the effect of improving physical activity and depression is obvious.

Can specific virtual reality combined with conventional rehabilitation improve poststroke hand motor function? A randomized clinical trial

TRIAL OBJECTIVE

To verify whether conventional rehabilitation combined with specific virtual reality is more effective than conventional therapy alone in restoring hand motor function and muscle tone after stroke.

TRIAL DESIGN

This prospective single-blind randomized controlled trial compared conventional rehabilitation based on physiotherapy and occupational therapy (control group) with the combination of conventional rehabilitation and specific virtual reality technology (experimental group). Participants were allocated to these groups in a ratio of 1:1. The conventional rehabilitation therapists were blinded to the study, but neither the participants nor the therapist who applied the virtual reality-based therapy could be blinded to the intervention.

PARTICIPANTS

Forty-six patients (43 of whom completed the intervention period and follow-up evaluation) were recruited from the Neurology and Rehabilitation units of the Hospital General Universitario of Talavera de la Reina, Spain.

INTERVENTION

Each participant completed 15 treatment sessions lasting 150 min/session; the sessions took place five consecutive days/week over the course of three weeks. The experimental group received conventional upper-limb strength and motor training (100 min/session) combined with specific virtual reality technology devices (50 min/session); the control group received only conventional training (150 min/session).

RESULTS

As measured by the Ashworth Scale, a decrease in wrist muscle tone was observed in both groups (control and experimental), with a notably larger decrease in the experimental group (baseline mean/postintervention mean: 1.22/0.39; difference between baseline and follow-up: 0.78; 95% confidence interval: 0.38-1.18; effect size = 0.206). Fugl-Meyer Assessment scores were observed to increase in both groups, with a notably larger increase in the experimental group (total motor function: effect size = 0.300; mean: - 35.5; 95% confidence interval: - 38.9 to - 32.0; wrist: effect size = 0.290; mean: - 5.6; 95% confidence interval: - 6.4 to - 4.8; hand: effect size = 0.299; mean: - -8.9; 95% confidence interval: - 10.1 to - 7.6). On the Action Research Arm Test, the experimental group quadrupled its score after the combined intervention (effect size = 0.321; mean: - 32.8; 95% confidence interval: - 40.1 to - 25.5).

CONCLUSION

The outcomes of the study suggest that conventional rehabilitation combined with a specific virtual reality technology system can be more effective than conventional programs alone in improving hand motor function and voluntary movement and in normalizing muscle tone in subacute stroke patients. With combined treatment, hand and wrist functionality and motion increase; resistance to movement (spasticity) decreases and remains at a reduced level.

Trunk training following stroke

BACKGROUND

Previous systematic reviews and randomised controlled trials have investigated the effect of post-stroke trunk training. Findings suggest that trunk training improves trunk function and activity or the execution of a task or action by an individual. But it is unclear what effect trunk training has on daily life activities, quality of life, and other outcomes.

OBJECTIVES

To assess the effectiveness of trunk training after stroke on activities of daily living (ADL), trunk function, arm-hand function or activity, standing balance, leg function, walking ability, and quality of life when comparing with both dose-matched as non-dose-matched control groups.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register, CENTRAL, MEDLINE, Embase, and five other databases to 25 October 2021. We searched trial registries to identify additional relevant published, unpublished, and ongoing trials. We hand searched the bibliographies of included studies.

SELECTION CRITERIA

We selected randomised controlled trials comparing trunk training versus non-dose-matched or dose-matched control therapy including adults (18 years or older) with either ischaemic or haemorrhagic stroke. Outcome measures of trials included ADL, trunk function, arm-hand function or activity, standing balance, leg function, walking ability, and quality of life.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Two main analyses were carried out. The first analysis included trials where the therapy duration of control intervention was non-dose-matched with the therapy duration of the experimental group and the second analysis where there was comparison with a dose-matched control intervention (equal therapy duration in both the control as in the experimental group).  MAIN RESULTS: We included 68 trials with a total of 2585 participants. In the analysis of the non-dose-matched groups (pooling of all trials with different training duration in the experimental as in the control intervention), we could see that trunk training had a positive effect on ADL (standardised mean difference (SMD) 0.96; 95% confidence interval (CI) 0.69 to 1.24; P < 0.001; 5 trials; 283 participants; very low-certainty evidence), trunk function (SMD 1.49, 95% CI 1.26 to 1.71; P < 0.001; 14 trials, 466 participants; very low-certainty evidence), arm-hand function (SMD 0.67, 95% CI 0.19 to 1.15; P = 0.006; 2 trials, 74 participants; low-certainty evidence), arm-hand activity (SMD 0.84, 95% CI 0.009 to 1.59; P = 0.03; 1 trial, 30 participants; very low-certainty evidence), standing balance (SMD 0.57, 95% CI 0.35 to 0.79; P < 0.001; 11 trials, 410 participants; very low-certainty evidence), leg function (SMD 1.10, 95% CI 0.57 to 1.63; P < 0.001; 1 trial, 64 participants; very low-certainty evidence), walking ability (SMD 0.73, 95% CI 0.52 to 0.94; P < 0.001; 11 trials, 383 participants; low-certainty evidence) and quality of life (SMD 0.50, 95% CI 0.11 to 0.89; P = 0.01; 2 trials, 108 participants; low-certainty evidence). Non-dose-matched trunk training led to no difference for the outcome serious adverse events (odds ratio: 7.94, 95% CI 0.16 to 400.89; 6 trials, 201 participants; very low-certainty evidence). In the analysis of the dose-matched groups (pooling of all trials with equal training duration in the experimental as in the control intervention), we saw that trunk training had a positive effect on trunk function (SMD 1.03, 95% CI 0.91 to 1.16; P < 0.001; 36 trials, 1217 participants; very low-certainty evidence), standing balance (SMD 1.00, 95% CI 0.86 to 1.15; P < 0.001; 22 trials, 917 participants; very low-certainty evidence), leg function (SMD 1.57, 95% CI 1.28 to 1.87; P < 0.001; 4 trials, 254 participants; very low-certainty evidence), walking ability (SMD 0.69, 95% CI 0.51 to 0.87; P < 0.001; 19 trials, 535 participants; low-certainty evidence) and quality of life (SMD 0.70, 95% CI 0.29 to 1.11; P < 0.001; 2 trials, 111 participants; low-certainty evidence), but not for ADL (SMD 0.10; 95% confidence interval (CI) -0.17 to 0.37; P = 0.48; 9 trials; 229 participants; very low-certainty evidence), arm-hand function (SMD 0.76, 95% CI -0.18 to 1.70; P = 0.11; 1 trial, 19 participants; low-certainty evidence), arm-hand activity (SMD 0.17, 95% CI -0.21 to 0.56; P = 0.38; 3 trials, 112 participants; very low-certainty evidence). Trunk training also led to no difference for the outcome serious adverse events (odds ratio (OR): 7.39, 95% CI 0.15 to 372.38; 10 trials, 381 participants; very low-certainty evidence). Time post stroke led to a significant subgroup difference for standing balance (P < 0.001) in non-dose-matched therapy. In non-dose-matched therapy, different trunk therapy approaches had a significant effect on ADL (< 0.001), trunk function (P < 0.001) and standing balance (< 0.001). When participants received dose-matched therapy, analysis of subgroup differences showed that the trunk therapy approach had a significant effect on ADL (P = 0.001), trunk function (P < 0.001), arm-hand activity (P < 0.001), standing balance (P = 0.002), and leg function (P = 0.002). Also for dose-matched therapy, subgroup analysis for time post stroke resulted in a significant difference for the outcomes standing balance (P < 0.001), walking ability (P = 0.003) and leg function (P < 0.001), time post stroke significantly modified the effect of intervention.  Core-stability trunk (15 trials), selective-trunk (14 trials) and unstable-trunk (16 trials) training approaches were mostly applied in the included trials.

AUTHORS' CONCLUSIONS

There is evidence to suggest that trunk training as part of rehabilitation improves ADL, trunk function, standing balance, walking ability, upper and lower limb function, and quality of life in people after stroke. Core-stability, selective-, and unstable-trunk training were the trunk training approaches mostly applied in the included trials. When considering only trials with a low risk of bias, results were mostly confirmed, with very low to moderate certainty, depending on the outcome.

Motivation as a Measurable Outcome in Stroke Rehabilitation: A Systematic Review of the Literature

Motivated behaviours are thought to lead to enhanced performances. In the neurorehabilitation field, motivation has been demonstrated to be a link between cognition and motor performance, therefore playing an important role upon rehabilitation outcome determining factors. While motivation-enhancing interventions have been frequently investigated, a common and reliable motivation assessment strategy has not been established yet. This review aims to systematically explore and provide a comparison among the existing motivation assessment tools concerning stroke rehabilitation. For this purpose, a literature search (PubMed and Google Scholar) was performed, using the following Medical Subject Headings terms: "assessment" OR "scale" AND "motivation" AND "stroke" AND "rehabilitation". In all, 31 randomized clinical trials and 15 clinical trials were examined. The existing assessment tools can be grouped into two categories: the first mirroring the trade-off between patients and rehabilitation, the latter reflecting the link between patients and interventions. Furthermore, we presented assessment tools which reflect participation level or apathy, as an indirect index of motivation. In conclusion, we are left to put forth a possible common motivation assessment strategy, which might provide valuable incentive to investigate in future research.

Effectiveness of feedback-based technology on physical and cognitive abilities in the elderly

Aging raises a social and health challenge because the passing of time causes changes in cognitive and physical functions that impair functionality and quality of life. In addition, advancements in technology and information technology have led to the development of new techniques for retraining based on the feedback technology provides. To solve the negative consequences of aging, a randomized clinical trial was carried out to assess the effectiveness of a protocol using feedback-based technology to improve physical and cognitive functions in older adults. For the purpose of this study, 200 patients were selected from a Social and Community Services Center in the province of Seville and only 46 of them became participants of the study (after applying the inclusion criteria). These patients were divided into two groups: control and experimental. Physical and cognitive abilities were assessed using the Miniexamen cognoscitivo Test (an adaptation of the MiniMental examination test), Yesevage's Depression Scale, Oddball Test, Attention Network Test, Berg Scale, Tinetti Scale, and Timed Up and Go Test. The intervention applied to the experimental group consisted of a supervised protocol using the Nintendo® Wii video game console and the Wii-Fit© video game during 16 sessions, 2 times a week with a duration of 30 min per session. The control group did not receive any treatment. The experimental group showed statistically significant improvements in all the physical variables (balance, gait, autonomy, and fall risk), as other authors had proven, and in memory and reaction times; there were no improvements in attention networks. The control group (placebo) even showed a decrease in their functions, with worse results on the Timed up and Go test Scale. The intervention using feedback-based technology has been proven effective in improving physical and cognitive abilities and in preventing and promoting healthy aging.

Interactive Videogame Improved Rehabilitation Motivation and Walking Speed in Chronic Stroke Patients: A Dual-Center Controlled Trial

Objective: This study aimed to evaluate the effectiveness of interactive video games (IVGs) in rehabilitation motivation and walking and balance abilities in chronic stroke patients. Materials and Methods: In this dual-center controlled trial, 24 chronic stroke patients from rehabilitation centers A and B were randomly assigned to an experimental (IVGs + traditional neurodevelopment treatment [TNT], n = 12) or a control group (walking training + TNT, n = 12). The patients in both the groups underwent TNT for 4 weeks (5 days/week) before undergoing either IVGs or walking training (4 weeks, 3 days/week) depending on the group. The primary and secondary outcomes were rehabilitation motivation and the Berg Balance Scale (BBS) score, Functional Reach Test (FRT) performance, and walking speed (WS), respectively. Results: The patients in both the groups showed significant increase in the BBS score, FRT performance, and WS; however, the experimental group showed more significant improvements in rehabilitation motivation (P = 0.02, η² = 0.415) and WS (P = 0.05, η² = 0.333) than the patients in the control group. Conclusion: This study suggests that the IVGs in combination with TNT provide effective rehabilitation motivation in chronic stroke patients. Clinical Trial Registration number: KCT0003408.

Kinect-Based Rehabilitation Systems for Stroke Patients: A Scoping Review

Method

This study was conducted according to Arksey and O'Malley's framework. To investigate the evidence on the effects of Kinect-based rehabilitation, a search was executed in five databases (Web of Science, PubMed, Cochrane Library, Scopus, and IEEE) from 2010 to 2020.

Results

Thirty-three articles were finally selected by the inclusion criteria. Most of the studies had been conducted in the US (22%). In terms of the application of Kinect-based rehabilitation for stroke patients, most studies had focused on the rehabilitation of upper extremities (55%), followed by balance (27%). The majority of the studies had developed customized rehabilitation programs (36%) for the rehabilitation of stroke patients. Most of these studies had noted that the simultaneous use of Kinect-based rehabilitation and other physiotherapy methods has a more noticeable effect on performance improvement in patients.

Conclusion

The simultaneous application of Kinect-based rehabilitation and other physiotherapy methods has a stronger effect on the performance improvement of stroke patients. Better effects can be achieved by designing Kinect-based rehabilitation programs tailored to the characteristics and abilities of stroke patients.

Effects of Balance Training Using a Virtual Reality Program in Hemiplegic Patients

Therapeutic goals for hemiplegic patients with neurological impairments are mainly focused on improving their independent lives. Based on the previously reported effectiveness of Wii Fit balance training, this study investigated the most influential outcomes after long-term intensive training (including balance and functional factors) on quality of life in hemiplegic patients. The intervention group (n = 21) received Nintendo Wii Fit balance training under supervision, and control group (n = 20) received conventional balance training by an occupational therapist. Two groups were matched based on age and onset duration. Both groups received a total of 15 treatments for 30 min per session, twice a week for 8 weeks. There were significant improvements not only in balance confidence and activities of daily living, but also in body composition, such as fat proportion and metabolic rate, in the intervention group compared to the control group (p < 0.05). In particular, balance confidence significantly affected EuroQoL Visual Analogue Scale according to stepwise multiple regression analyses in this study. These results demonstrated that Wii Fit balance training using virtual reality improved the quality of life of hemiplegic patients while overcoming the asymmetrical weight distribution of the affected side via the self-modulating biofeedback exercises.

Applying Game-Based Approaches for Physical Rehabilitation of Poststroke Patients: A Systematic Review

Objective

A large number of patients need critical physical rehabilitation after the stroke. This study aimed to review and report the result of published studies, in which newly emerged games were employed for physical rehabilitating in poststroke patients.

Materials and Methods

This systematic review study was performed based on the PRISMA method. A comprehensive search of PubMed, Scopus, IEEE Xplore Digital Library, and ISI Web of Science was conducted from January 1, 2014, to November 9, 2020, to identify related articles. Studies have been entered in this review based on inclusion and exclusion criteria, in which new games have been used for physical rehabilitation.

Results

Of the 1326 retrieved studies, 60 of them met our inclusion criteria. Virtual reality-oriented games were the most popular type of physical rehabilitation approach for poststroke patients. “The Nintendo Wii Fit” game was used more than other games. The reviewed games were mostly operated to balance training and limb mobilization. Based on the evaluation results of the utilized games, only in three studies, applied games were not effective. In other studies, games had effective outcomes for target body members.

Conclusions

The results indicate that modern games are efficient in poststroke patients' physical rehabilitation and can be used alongside conventional methods.

Effects of game-based rehabilitation on upper limb function in adults within the first six months following stroke: protocol for a systematic review and meta-analysis

OBJECTIVE

To evaluate and summarize the level of evidence for the immediate, short-term, and long-term effects of game-based rehabilitation on upper limb function in adults within the first six months following stroke.

INTRODUCTION

A game-based intervention is a valuable therapeutic tool for incorporating principles of motor learning and neuroplasticity in the rehabilitation of upper limb function post-stroke. Most of the existing reviews on game-based rehabilitation are focused on the chronic phase of stroke. However, as maximum upper limb motor recovery occurs in the first six months after stroke, further exploration of the effects of game-based rehabilitation in this phase is necessary.

INCLUSION CRITERIA

We will include randomized clinical trials assessing the immediate, short-term, and long-term effects of game-based rehabilitation on upper limb function in adults within the first six months following stroke.

METHODS

The systematic review will follow the Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) checklist and JBI methodology for systematic reviews of effectiveness. A database-specific search strategy will be used in CINAHL, PubMed, Scopus, Web of Science, ProQuest, PEDro, OT Seeker, and Ovid MEDLINE to identify studies in the English language with no date limit. Two reviewers will independently screen, extract data from, and assess risk of bias in the eligible studies. Meta-analysis and publication bias evaluation will be done when adequate data are available. If a meta-analysis is precluded, then a narrative synthesis will be done. The Grading of Recommendations Assessment Development and Evaluation (GRADE) criteria will be used to assess the certainty of evidence for the outcome measures of interest.

Effects of Specific Virtual Reality-Based Therapy for the Rehabilitation of the Upper Limb Motor Function Post-Ictus: Randomized Controlled Trial

This research analyzed the combined effect of conventional treatment and virtual reality exposure therapy on the motor function of the upper extremities in people with stroke. We designed a randomized controlled trial set in the rehabilitation and neurology departments of a hospital (Talavera de la Reina, Spain). The subjects included 43 participants, all randomized into experimental (conventional treatment + virtual reality exposure therapy) and control group (conventional treatment).; The main measures were Fugl-Meyer Assessment for upper extremity, Modified Ashworth Scale, and Stroke Impact Scale 3.0. The results included 23 patients in the experimental (62.6 ± 13.5 years) and 20 in the control group (63.6 ± 12.2 years) who completed the study. After the intervention, muscle tone diminished in both groups, more so in the experimental group (mean baseline/post-intervention: from 1.30 to 0.60; η² = 0.237; p = 0.001). Difficulties in performing functional activities that implicate the upper limb also diminished. Regarding the global recovery from stroke, both groups improved scores, but the experimental group scored significantly higher than the controls (mean baseline/post-intervention: from 28.7 to 86.5; η² = 0.633; p = 0.000). In conclusion, conventional rehabilitation combined with specific virtual reality seems to be more efficacious than conventional physiotherapy and occupational therapy alone in improving motor function of the upper extremities and the autonomy of survivors of stroke in activities of daily living.

Effects of Virtual Reality-Based Therapy on Quality of Life of Patients with Subacute Stroke: A Three-Month Follow-Up Randomized Controlled Trial

Objective: To evaluate the influence of conventional rehabilitation combined with virtual reality on improving quality of life related to post-stroke health. Design: Randomized controlled trial. Setting: Rehabilitation and neurology departments of a general hospital (Talavera de la Reina, Spain). Subjects: A total of 43 participants with subacute stroke. Intervention: Participants were randomized into experimental group (conventional treatment + virtual reality) and control (conventional treatment). Main measures: Health-related quality of life as measured by the EuroQoL-5 dimensions instrument (EQ-5D-5L) and EuroQoL visual analog scale (EQ-VAS). Results: A total of 23 patients in the experimental group (62.6 ± 13.5 years) and 20 in the control (63.6 ± 12.2 years) completed the study. In the experimental group, EQ-VAS score was 29.1 ± 12.8 at baseline, 86.5 ± 7.1 post-intervention, and 78.3 ± 10.3 at the three-month follow-up. The control group obtained scores of 25.5 ± 5.1, 57.0 ± 4.7, and 58.5 ± 5.9, respectively. We identified significant differences at the post-intervention and follow-up timepoints (p = 0.000) and a partial η² of 0.647. In EQ-5D-5L, the severity of issues decreased after intervention in the experimental group, while pain and anxiety dimensions increased between post-intervention and follow-up. Conclusions: The conventional rehabilitative approach combined with virtual reality appears to be more effective for improving the perceived health-related quality of life in stroke survivors.
