Comparison of individualized virtual reality- and group-based rehabilitation in older adults with chronic stroke in community settings: a pilot randomized controlled trial

Effect of virtual reality-based upper limb training on activity of daily living and quality of life among stroke survivors: a systematic review and meta-analysis

BACKGROUND

Stroke is a leading cause of disability worldwide, significantly impairing upper limb (UL) function and reducing patients' ability to perform activities of daily living (ADL) and quality of life (QoL). Virtual reality (VR) has emerged as a promising tool for UL rehabilitation, offering immersive and engaging environments for motor recovery. However, the effectiveness of VR, its integration with conventional therapy, and their efficacy across different stroke recovery stages remain unclear. Therefore, this systematic review and meta-analysis aimed to evaluate the effectiveness of VR-based UL interventions in improving ADL and QoL among stroke survivors.

METHOD

This study adhered to PRISMA guidelines and was registered on PROSPERO (CRD42023426256). A systematic search of PubMed, Scopus, and Web of Science identified randomized controlled trials (RCTs) published in English. Inclusion criteria focused on studies using immersive VR (IVR) and non-immersive VR (NIVR) interventions to assess ADL and QoL in stroke survivors. Data extraction and quality assessment were performed independently by two reviewers using the PEDro scale to assess quality. Meta-analyses were conducted to determine the efficacy. Subgroup analyses were performed to compare IVR and NIVR, VR combined with conventional therapy versus standalone VR, and potential differences between stroke recovery stages.

RESULT

Thirty RCTs, representing 1,661 participants, were included. Overall, VR interventions significantly improved ADL (SMD = 0.27, 95% CI [0.11; 0.43], p < 0.001) and QoL (SMD = 0.94 [0.09; 1.79], p = 0.035) compared to conventional therapy. IVR demonstrated superior outcomes for ADL compared to NIVR (SMD = 0.54 [0.13; 0.95] Vs. 0.17 [0.02; 0.36], p = 0.03). Subacute stroke survivors exhibited the most significant gains in ADL (SMD = 0.52 [0.16; 0.88], p = 0.004), compared to chronic (SMD = 0.05 [-0.36; 0.46]) or acute patients (SMD = 0.08 [-0.11; 0.27]).

CONCLUSION

VR interventions, particularly IVR and VR combined with conventional therapy, significantly enhance ADL and QoL in stroke survivors with moderate certainty of evidence. These findings underscore the value of VR in rehabilitation, especially during the subacute phase, but highlight the need for further research into long-term effects and implementation in low-resource settings.

Effects of virtual reality with different modalities on upper limb recovery: a systematic review and network meta-analysis on optimizing stroke rehabilitation

Background

As a major cause of disability worldwide, stroke affects about 80% of survivors with upper limb (UL) motor dysfunction, significantly impairing their quality of life. Virtual reality (VR) has been recognized as an innovative rehabilitation tool; however, the effectiveness of VR systems with different immersion modalities is still uncertain. This systematic review and network meta-analysis (NMA) aims to evaluate the comparative effectiveness of intervention measures, including non-immersive gaming consoles, immersive VR (IVR), non-immersive VR (NIVR), and conventional therapy (CT) on upper limb motor function in stroke rehabilitation.

Materials and methods

A systematic search of PubMed, Embase, Cochrane Library, and Scopus identified randomized controlled trials (RCTs) published up to 12 June 2024. UL motor recovery was assessed using the Fugl-Meyer Upper Extremity (FMUE) scale. The NMA was performed using the Bayesian approach with the BUGSnet package in R software to calculate the relative effectiveness of each intervention.

Results

34 RCTs involving 1,704 participants were included. Among non-immersive gaming systems, Microsoft Kinect demonstrated the greatest effective in enhancing UL motor function, followed by Nintendo Wii, then NIVR and IVR head-mounted devices. CT showed the least effective. Specifically, Microsoft Kinect significantly improved FMUE scores (mean difference [MD] = 7.27, 95% confidence interval [CI]: 0.59 to 13.77, p < 0.05), followed by Nintendo Wii (MD = 4.53, 95% CI: 0.87 to 8.14, p < 0.05), and NIVR (MD = 3.57, 95% CI: 1.18 to 6.01, p < 0.05). In contrast, IVR head-mounted devices showed no statistically significant differences in outcomes, with MD of 4.16 (95% CI: -0.02 to 8.38).

Conclusion

Non-immersive gaming console of Microsoft Kinect is the most effective intervention for improving UL motor function in stroke survivors. In contrast, IVR head-mounted devices did not offer significant advantages over CT. These findings suggest that non-immersive gaming consoles of Microsoft Kinect could be a more cost-effective and accessible alternative for stroke rehabilitation.

Effect of Virtual Reality-Based Rehabilitation on Mental Health and Quality of Life of Stroke Patients: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVES

To conduct a meta-analysis to investigate the effect of virtual reality (VR)-based rehabilitation on the mental health and quality of life of stroke patients.

DATA SOURCES

The search strategy was conducted in 5 databases (PubMed, Scopus, Web of Science, Embase, and Cochrane Library databases) from inception to December 2023.

STUDY SELECTION

Randomized controlled trials (RCTs) comparing the effectiveness of standard rehabilitation and VR-based rehabilitation for stroke patients.

DATA EXTRACTION

Data from the included articles were extracted independently by 2 authors, with any disagreements resolved through consultation with a third author. The extracted data included the first author's name, country/region, publication year, sample size, mean/median age of participants, sex distribution (the proportion of males), VR type, duration of rehabilitation, comparison, intervention, and assessment of outcome.

DATA SYNTHESIS

A total of 29 studies involving 1561 stroke patients were included. The results showed that compared with standard rehabilitation, VR-based rehabilitation remarkably reduced anxiety symptoms [SMD=-0.97 (95% CI [-1.84, -0.09], P<.0001)], depression symptoms [SMD=-0.94 (95% CI [-1.46, -0.42], P<.001)], and improved quality of life [SMD=0.94 (95% CI [0.42, 1.45], P<.001)] of stroke patients. Subgroup analysis showed that immersive VR was particularly effective in reducing anxiety and depression symptoms compared to nonimmersive VR. The longer the duration of VR intervention, exceeding 6 weeks, the more significant the effect of improving anxiety and depression symptoms. Meanwhile, VR-based rehabilitation significantly improved the psychological state and quality of life of European patients.

CONCLUSIONS

VR-based rehabilitation significantly reduces anxiety and depression symptoms and enhances the quality of life in stroke patients compared to standard rehabilitation. The most notable improvements were observed with immersive VR-based rehabilitation programs over 6 weeks in duration, particularly among European patients.

Virtual Reality Therapy for Upper Limb Motor Impairments in Patients With Stroke: A Systematic Review and Meta-Analysis

BACKGROUND AND PURPOSE

Stroke is a major cause of disability in adults. Motor recovery through conventional therapy (CT) is a fundamental approach but can sometimes face challenges related to motivation. Virtual reality (VR) rehabilitation, specifically non-immersive VR, is an alternative therapy aimed at improving upper limb motor function and, consequently, functional independence in daily living activities. However, its effectiveness is still being evaluated. Therefore, a meta-analysis was conducted to evaluate the effectiveness of non-immersive VR in upper limb motor function, manual dexterity and the improvement of daily living activities in stroke patients.

METHODS

The control groups included physical therapy or occupational therapy. We searched IEEE Digital Library, PubMed, SciELO, Scopus, PEDro, Web of Sciences and ScienceDirect until December 2023 and identified randomized controlled trials (RCTs). Quality and risk were assessed using the revised Cochrane Collaboration tool, PEDro scale, OCEBM, and GRADE. Publication bias and sensitivity analyses were also evaluated. The standardized mean difference (SMD) effect size was calculated to assess the effectiveness of VR therapy compared with conventional therapy. Subgroup analyses were subsequently performed to mitigate the observed heterogeneity and provide further clarity to the results.

RESULTS

In line with previous research, using VR shows improvements in motor function and manual dexterity for stroke patients. Subgroup analyses reveal that the benefits of VR interventions are most pronounced during the acute and subacute recovery stages, particularly in motor function and manual dexterity. Furthermore, combining VR with traditional therapy seems to yield better outcomes in motor function and manual dexterity compared with VR alone. Notably, the type of VR control-whether sensory or manual-or whether the game is commercially available or rehabilitation-specific, does not seem to influence the outcomes. VR interventions lasting less than 4 weeks are effective in improving both motor function and manual dexterity, whereas interventions of 4 weeks or longer only show significant benefits in motor function.

DISCUSSION

These findings highlight the versatility and potential of VR as a complementary tool in neurorehabilitation.

Quantifying patient experiences with therapeutic neurorehabilitation technologies: a scoping review

PURPOSE

Neurorehabilitation technologies are a novel approach to providing rehabilitation for patients with neurological conditions. There is a need to explore patient experiences. This study aimed; 1) To identify available questionnaires that assess patients' experiences with neurorehabilitation technologies, and 2) where reported, to document the psychometric properties of the identified questionnaires.

MATERIALS AND METHODS

Four databases were searched (Medline, Embase, Emcare and PsycInfo). The inclusion criteria were all types of primary data collection that included neurological patients of all ages who had experienced therapy with neurorehabilitation technologies and completed questionnaires to assess these experiences.

RESULTS

Eighty-eight publications were included. Fifteen different questionnaires along with many self-developed scales were identified. These were categorised as; 1) self-developed tools, 2) specific questionnaire for a particular technology, and 3) generic questionnaires originally developed for a different purpose. The questionnaires were used to assess various technologies, including virtual reality, robotics, and gaming systems. Most studies did not report any psychometric properties.

CONCLUSION

Many tools have been used to evaluate patient experiences, but few were specifically developed for neurorehabilitation technologies and psychometric data was limited. A preliminary recommendation would be use of the User Satisfaction Evaluation Questionnaire to evaluate patient experience with virtual reality systems.

Behavior Change Approaches in Digital Technology-Based Physical Rehabilitation Interventions Following Stroke: Scoping Review

BACKGROUND

Digital health technologies (DHTs) are increasingly used in physical stroke rehabilitation to support individuals in successfully engaging with the frequent, intensive, and lengthy activities required to optimize recovery. Despite this, little is known about behavior change within these interventions.

OBJECTIVE

This scoping review aimed to identify if and how behavior change approaches (ie, theories, models, frameworks, and techniques to influence behavior) are incorporated within physical stroke rehabilitation interventions that include a DHT.

METHODS

Databases (Embase, MEDLINE, PsycINFO, CINAHL, Cochrane Library, and AMED) were searched using keywords relating to behavior change, DHT, physical rehabilitation, and stroke. The results were independently screened by 2 reviewers. Sources were included if they reported a completed primary research study in which a behavior change approach could be identified within a physical stroke rehabilitation intervention that included a DHT. Data, including the study design, DHT used, and behavior change approaches, were charted. Specific behavior change techniques were coded to the behavior change technique taxonomy version 1 (BCTTv1).

RESULTS

From a total of 1973 identified sources, 103 (5%) studies were included for data charting. The most common reason for exclusion at full-text screening was the absence of an explicit approach to behavior change (165/245, 67%). Almost half (45/103, 44%) of the included studies were described as pilot or feasibility studies. Virtual reality was the most frequently identified DHT type (58/103, 56%), and almost two-thirds (65/103, 63%) of studies focused on upper limb rehabilitation. Only a limited number of studies (18/103, 17%) included a theory, model, or framework for behavior change. The most frequently used BCTTv1 clusters were feedback and monitoring (88/103, 85%), reward and threat (56/103, 54%), goals and planning (33/103, 32%), and shaping knowledge (33/103, 32%). Relationships between feedback and monitoring and reward and threat were identified using a relationship map, with prominent use of both of these clusters in interventions that included virtual reality.

CONCLUSIONS

Despite an assumption that DHTs can promote engagement in rehabilitation, this scoping review demonstrates that very few studies of physical stroke rehabilitation that include a DHT overtly used any form of behavior change approach. From those studies that did consider behavior change, most did not report a robust underpinning theory. Future development and research need to explicitly articulate how including DHTs within an intervention may support the behavior change required for optimal engagement in physical rehabilitation following stroke, as well as establish their effectiveness. This understanding is likely to support the realization of the transformative potential of DHTs in stroke rehabilitation.

Personalization Characteristics and Evaluation of Gamified Exercise for Middle-Aged and Older People: A Scoping Review

Many studies have shown that personalized exergames have a positive effect on promoting regular and proper exercise. However, there is no consensus on the design characteristics and evaluation of exergames. This systematic review of published research literature aimed to explore the general characteristics, personalization characteristics, and evaluation of personalized exergames for middle-aged and older people. We screened published studies in the Web of Science, Scopus, PubMed, ACM, and IEEE Xplore databases, extracted data, and performed a thematic analysis according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist. Three main themes and nine subthemes were generated from 24 included papers. Moreover, a personalization model (FACTS) and evaluation system (PMSS) of exergames were developed. Personalized exergames had potential positive effects on motivating middle-aged and older people to exercise and improve their health, particularly physical, mental, and social health. However, more fine-grained studies on personalized exergames are necessary in the future.

Effect of Physiotherapy Treatment with Immersive Virtual Reality in Subjects with Stroke: A Protocol for a Randomized Controlled Trial

BACKGROUND

Many stroke survivors suffer from sensorimotor deficits, especially balance impairments. The purpose of this trial is to investigate whether the designed Immersive Virtual Reality training program is better in the short term (15 sessions) and in the medium term (30 sessions) than physiotherapy training with Bayouk, Boucher and Leroux exercises, with respect to static balance in sitting and standing, dynamic balance and quality of life in patients with balance impairment in stroke survivors.

METHODS

This study is a randomized controlled trial with two treatment arms and evaluators blinded, and a functionality treatment group in combination with specific balance exercise training according to Bayouk, Boucher and Leroux (control group) or a balanced treatment using Immersive VR. The primary outcome will be static, Dynamic balance and gait measured by Bestest Assessment Score (BESTest), Berg Scale (BBS), Pass Scale (PASS) and Time Up and Go test (TUG). The secondary outcome will be the stroke-associated quality of life using the Stroke Quality of Life Scale (ECVI-38).

CONCLUSIONS

The results of this study may add new insights into how to address balance using Immersive Virtual Reality after a stroke. If the new training approach proves effective, the results may provide insight into how to design more comprehensive protocols in the future for people with balance impairments after stroke.

Comparison of immersive and non-immersive virtual reality for upper extremity functional recovery in patients with stroke: a systematic review and network meta-analysis

OBJECTIVE

This systematic review aimed to compare the effects of immersive and non-immersive virtual reality on upper extremity function in stroke survivors by employing a network meta-analysis approach.

DATA SOURCES

MEDLINE, Embase, CINAHL Plus, APA PsycINFO, and Scopus were searched. Virtual reality was used for upper extremity rehabilitation; dose-matched conventional rehabilitation was used for comparison. Fugl-Meyer Assessment was used to assess upper extremity function. Searches were limited to English language randomized controlled trials.

METHODS

Two independent reviewers conducted study selection, data extraction, and quality assessment. Methodological quality was assessed using the Physiotherapy Evidence Database scale. A random-effects frequentist network meta-analysis was conducted by assuming a common random-effects standard deviation for all comparisons in the network.

RESULTS

Twenty randomized controlled trials with 813 participants were included, with each study evaluated as good quality. Immersive virtual reality systems were most effective at improving upper extremity function, followed by non-immersive virtual reality systems, then non-immersive gaming consoles of Microsoft Kinect and Nintendo Wii. Conventional rehabilitation was least effective. Immersive virtual reality was estimated to induce 1.39 (95% confidence interval (CI): 0.25, 2.53) and 1.38 (95% CI: 0.55, 2.20) standard mean differences of improvements in upper extremity function, compared to Nintendo Wii intervention and conventional rehabilitation, respectively.

CONCLUSION

This systematic review and network meta-analysis highlights the superior effects of immersive virtual reality to non-immersive virtual reality systems and gaming consoles on upper extremity motor recovery.

Post-Stroke Experiences and Rehabilitation Needs of Community-Dwelling Chinese Stroke Survivors: A Qualitative Study

Stroke survivors encounter significant limitations in daily life activities and face increased risk of health complications such as stroke recurrence. Considering the escalating demand for personalised community rehabilitation services, this qualitative study was conducted to understand the current recovery experiences, needs, and expectations of community-dwelling stroke survivors. Fifty stroke survivors were recruited from two tertiary teaching hospitals and community centres in two provinces in mainland China. Semi-structured interviews were carried out, and participants were asked to describe their experiences of stroke, current lifestyles, exercise habits, and rehabilitation needs and expectations. Resulting data were thematically analysed. The majority of participants were first-time stroke survivors (80%) and lived with their family or caregivers (92%). Four main themes and twelve sub-themes emerged from the data: (1) shifts in social life, (2) shaken sense of self and perceived helplessness, (3) complex rehabilitation needs, and (4) perceptions and patterns of physical activity. Findings suggest that though survivors recognised their need for further rehabilitation, their demands remained unmet due to a combination of personal and external factors such as limited mobility and the absence of supportive companions and accessible facilities. The enhancement and diversification of home rehabilitation strategies are therefore necessary to make community rehabilitation more accessible and equitable.

Examining the effectiveness of virtual, augmented, and mixed reality (VAMR) therapy for upper limb recovery and activities of daily living in stroke patients: a systematic review and meta-analysis

INTRODUCTION

Virtual reality (VR), augmented reality (AR), and mixed reality (MR) are emerging technologies in the field of stroke rehabilitation that have the potential to overcome the limitations of conventional treatment. Enhancing upper limb (UL) function is critical in stroke impairments because the upper limb is involved in the majority of activities of daily living (ADL).

METHODS

This study reviewed the use of virtual, augmented and mixed reality (VAMR) methods for improving UL recovery and ADL, and compared the effectiveness of VAMR treatment to conventional rehabilitation therapy. The databases ScienceDirect, PubMed, IEEE Xplore, and Web of Science were examined, and 50 randomized control trials comparing VAMR treatment to standard therapy were determined. The random effect model and fixed effect model are applied based on heterogeneity.

RESULTS

The most often used outcomes of UL recovery and ADL in stroke rehabilitation were the Fugl-Meyer Assessment for Upper Extremities (FMA-UE), followed by the Box and Block Test (BBT), the Wolf Motor Function Test (WMFT), and the Functional Independence Measure (FIM). According to the meta-analysis, VR, AR, and MR all have a significant positive effect on improving FMA-UE for UL impairment (36 studies, MD = 3.91, 95 percent CI = 1.70-6.12, P = 0.0005) and FIM for ADL (10 studies, MD = 4.25, 95 percent CI = 1.47-7.03, P = 0.003), but not on BBT and WMFT for the UL function tests (16 studies, MD = 2.07, 95 percent CI = - 0.58-4.72, P = 0.13), CONCLUSIONS: VAMR therapy was superior to conventional treatment in UL impairment and daily function outcomes, but not UL function measures. Future studies might include further high-quality trials examining the effect of VR, AR, and MR on UL function measures, with an emphasis on subgroup meta-analysis by stroke type and recovery stage.

Effectiveness of Using Virtual Reality-Supported Exercise Therapy for Upper Extremity Motor Rehabilitation in Patients With Stroke: Systematic Review and Meta-analysis of Randomized Controlled Trials

Background

In recent years, efforts have been made to implement virtual reality (VR) to support the delivery of poststroke upper extremity motor rehabilitation exercises. Therefore, it is important to review and analyze the existing research evidence of its effectiveness.

Objective

Through a systematic review and meta-analysis of randomized controlled trials, this study examined the effectiveness of using VR-supported exercise therapy for upper extremity motor rehabilitation in patients with stroke.

Methods

This study followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The CINAHL Plus, MEDLINE, Web of Science, Embase, and Cochrane Library databases were searched on December 31, 2021. Changes in outcomes related to impairments in upper extremity functions and structures, activity limitations, and participation restrictions in life situations from baseline to after intervention, after intervention to follow-up assessment, and baseline to follow-up assessment were examined. Standardized mean differences (SMDs) were calculated using a random-effects model. Subgroup analyses were performed to determine whether the differences in treatment outcomes depended on age, stroke recovery stage, VR program type, therapy delivery format, similarities in intervention duration between study groups, intervention duration in VR groups, and trial length.

Results

A total of 42 publications representing 43 trials (aggregated sample size=1893) were analyzed. Compared with the control groups that used either conventional therapy or no therapy, the intervention groups that used VR to support exercise therapy showed significant improvements in upper extremity motor function (Fugl-Meyer Assessment-Upper Extremity; SMD 0.45, 95% CI 0.21-0.68; P<.001), range of motion (goniometer; SMD 1.01, 95% CI 0.50-1.52; P<.001), muscle strength (Manual Muscle Testing; SMD 0.79, 95% CI 0.28-1.30; P=.002), and independence in day-to-day activities (Functional Independence Measure; SMD 0.23, 95% CI 0.06-0.40; P=.01, and modified Rankin Scale; SMD 0.57, 95% CI 0.01-1.12; P=.046). Significant subgroup differences were observed in hand dexterity (Box and Block Test), spasticity (Ashworth Scale or modified Ashworth Scale), arm and hand motor ability (Wolf Motor Function Test and Manual Function Test), hand motor ability (Jebsen Hand Function Test), and quality of life (Stroke Impact Scale). There was no evidence that the benefits of VR-supported exercise therapy were maintained after the intervention ended.

Conclusions

VR-supported upper extremity exercise therapy can be effective in improving motor rehabilitation results. Our review showed that of the 12 rehabilitation outcomes examined during the course of VR-based therapy, significant improvements were detected in 2 (upper extremity motor function and range of motion), and both significant and nonsignificant improvements were observed in another 2 (muscle strength and independence in day-to-day activities), depending on the measurement tools or methods used.

Effect of Time-Dose-Matched Virtual Reality Therapy on Upper Limb Dysfunction in Patients Poststroke: A Meta-Analysis of Randomized Controlled Trials

OBJECTIVE

To investigate the efficacy and acceptability of virtual reality (VR) with time-dose-matched conventional therapy (CT) in patients poststroke with upper limb dysfunction.

DATA SOURCES

Cochrane, PubMed, Web of Science, Embase, and ProQuest were systematically searched up to May 24, 2021.

STUDY SELECTION

Randomized controlled trials comparing VR with time-dose-matched CT in patients poststroke with upper limb dysfunction were included.

DATA EXTRACTION

The extracted data included efficacy (mean change in structure/function, activity, and participation scores), acceptability (dropouts for all reasons), adverse events, and characteristics of the included studies. The Cochrane risk of bias assessment tool was used to assess the risk of bias.

DATA SYNTHESIS

Thirty-one randomized controlled trails were included. VR was superior to time-dose-matched CT in terms of the World Health Organization's International Classification of Functioning, Disability and Health structure/function, with a standardized mean difference (SMD) of 0.35, but not activity and participation. Subgroup analyses demonstrated that virtual environment was superior to CT in structure/function (SMD=0.38) and activity (SMD=0.27), whereas there were no significant differences between commercial gaming and CT in any World Health Organization International Classification of Functioning, Disability and Health domain. VR mixed with CT was more effective than time-dose-matched CT in structure/function (SMD=0.56), whereas VR only was not significantly different from CT. There were no significant differences in the incidence of adverse events and dropout rates between VR and CT.

CONCLUSIONS

The results suggest that VR is superior to time-dose-matched CT in terms of recovery of upper extremity motor function, especially when a virtual environment is used or VR is mixed with CT. However, VR (VR only or mixed with CT) does not improve patients' daily activity performance and participation compared with CT. Overall, VR appears to be safe and acceptable as CT. Large-scale definitive trials are needed to verify or refute these findings.

Effects of Immersive and Non-Immersive Virtual Reality on the Static and Dynamic Balance of Stroke Patients: A Systematic Review and Meta-Analysis

(1) Background: The development of new technologies means that the use of virtual reality is increasingly being implemented in rehabilitative approaches for adult stroke patients.

OBJECTIVE

To analyze the existing scientific evidence regarding the application of immersive and non-immersive virtual reality in patients following cerebrovascular incidents and their efficacy in achieving dynamic and static balance. (2) Data sources: An electronic search of the databases Medline, Cochrane Library, PEDro, Scopus, and Scielo from January 2010 to December 2020 was carried out using the terms physiotherapy, physical therapy, virtual reality, immersive virtual reality, non-immersive virtual reality, stroke, balance, static balance, and dynamic balance.

SELECTION OF STUDIES

Randomized controlled trials in patients older than 18 developed with an adult population (>18 years old) with balance disorders as a consequence of suffering a stroke in the previous six months before therapeutic intervention, including exercises harnessing virtual reality in their interventions and evaluations of balance and published in English or Spanish, were included. A total of two hundred twenty-seven articles were found, ten of which were included for review and of these, nine were included in the subsequent meta-analysis. (3) Data extraction: Two authors selected the studies and extracted their characteristics (participants, interventions, and validation instruments) and results. The methodological quality of the studies was evaluated using the PEDro scale, and the risk of bias was determined using the Cochrane risk-of-bias tool.

DATA SYNTHESIS

Of the selected studies, three did not show significant improvements and seven showed significant improvements in the intervention groups in relation to the variables. (4) Conclusions: Non-immersive virtual reality combined with conventional rehabilitation could be considered as a therapeutic option.

Serious games for upper limb rehabilitation after stroke: a meta-analysis

BACKGROUND

Approximately two thirds of stroke survivors maintain upper limb (UL) impairments and few among them attain complete UL recovery 6 months after stroke. Technological progress and gamification of interventions aim for better outcomes and constitute opportunities in self- and tele-rehabilitation.

OBJECTIVES

Our objective was to assess the efficacy of serious games, implemented on diverse technological systems, targeting UL recovery after stroke. In addition, we investigated whether adherence to neurorehabilitation principles influenced efficacy of games specifically designed for rehabilitation, regardless of the device used.

METHOD

This systematic review was conducted according to PRISMA guidelines (PROSPERO registration number: 156589). Two independent reviewers searched PubMed, EMBASE, SCOPUS and Cochrane Central Register of Controlled Trials for eligible randomized controlled trials (PEDro score ≥ 5). Meta-analysis, using a random effects model, was performed to compare effects of interventions using serious games, to conventional treatment, for UL rehabilitation in adult stroke patients. In addition, we conducted subgroup analysis, according to adherence of included studies to a consolidated set of 11 neurorehabilitation principles.

RESULTS

Meta-analysis of 42 trials, including 1760 participants, showed better improvements in favor of interventions using serious games when compared to conventional therapies, regarding UL function (SMD = 0.47; 95% CI = 0.24 to 0.70; P < 0.0001), activity (SMD = 0.25; 95% CI = 0.05 to 0.46; P = 0.02) and participation (SMD = 0.66; 95% CI = 0.29 to 1.03; P = 0.0005). Additionally, long term effect retention was observed for UL function (SMD = 0.42; 95% CI = 0.05 to 0.79; P = 0.03). Interventions using serious games that complied with at least 8 neurorehabilitation principles showed better overall effects. Although heterogeneity levels remained moderate, results were little affected by changes in methods or outliers indicating robustness.

CONCLUSION

This meta-analysis showed that rehabilitation through serious games, targeting UL recovery after stroke, leads to better improvements, compared to conventional treatment, in three ICF-WHO components. Irrespective of the technological device used, higher adherence to a consolidated set of neurorehabilitation principles enhances efficacy of serious games. Future development of stroke-specific rehabilitation interventions should further take into consideration the consolidated set of neurorehabilitation principles.

Exergaming for Quality of Life in Persons Living with Chronic Diseases: A Systematic Review and Meta-analysis

OBJECTIVE

To evaluate the evidence of effectiveness of exergame-based rehabilitative interventions on health-related quality of life (HRQoL) in persons with chronic diseases. TYPE: Systematic review and meta-analysis.

LITERATURE SURVEY

Randomized and nonrandomized controlled trials of exergame rehabilitation interventions in populations with chronic diseases reporting HRQoL outcomes were identified by searching PubMed, Scopus, Physiotherapy Evidence Database (PEDro), Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar, using keywords and MeSH terms for papers published between January 2005 and March 2019.

METHODOLOGY

Risk of bias was assessed by using the PEDro scale. The Grading of Recommendation, Assessment, Development and Evaluation (GRADE) system was used to score the quality of evidence. Pooled effects were reported as standardized mean differences (SMDs) or weighted mean difference (MDs) and 95% confidence intervals (CIs), using a random-effects model. Heterogeneity was weighted by inconsistency I² tests.

SYNTHESIS

Thirty-four trials were identified (1594 participants). Overall, the evidence was low quality. Exergames significantly improved HRQoL in populations with chronic diseases, with a small effect size (32 studies; 1544 participants; SMD 0.24; 95% CI 0.1 to 0.4; I²  = 27%) and specifically in people with neurological disorders (20 studies, 956 participants, SMD 0.22; 95% CI 0.2 to 0.4; I²  = 49%), rheumatologic diseases (four studies, 210 participants, SMD 0.39; 95% CI 0.1 to 0.7; I²  = 4%), and cardiorespiratory and chronic metabolic conditions (five studies, 309 participants, SMD 0.23; 95% CI 0.0 to 0.5; I²  = 0%). Exergaming interventions in health care settings demonstrated similarly small but positive effects (22 studies, 905 participants, SMD 0.30; 95% CI 0.1 to 0.5; I²  = 41%), whereas those carried out in home-based contexts did not.

CONCLUSIONS

Exergame-based rehabilitative interventions performed in health care settings led to small but statistically significant improvements in HRQoL in persons with chronic diseases.

Telerehabilitation System in Nursing Post Stroke - A Systematic Review

Background: Stroke is currently the main cause of disability worldwide. Telerehabilitation is a rehabilitation approach that can be used to repair the damage to motor, sensory and cognitive functions. This can also substantially reduce the travel time for the health workers and therefore increase the number of patients who are consulted in a day.Method: A search using specific keywords was done in both the journal articles and in the database. In total, 119 articles were from Scopus, 45 articles were from PubMed, 87 articles were from Science Direct, 52 articles were from EBSCO and 97 articles were from Proquest. There were 15 articles that matched the inclusion criteria. Most of the available literature only refers to short-term results and most of the research is of low quality.Result: Evidence of the relative effectiveness was found in the types of videos, VR, cellphones and computer use. The location of the network support and technological progress are still obstacles that must be addressed immediately. Based on the current scientific evidence, only a few telerehabilitation methods can be recommended for wider use.Conclusion: The telerehabilitation system can provide long-term therapy, meet the patient needs and save the health resources needed to minimize the severity of the patients’ condition. The application of telerehabilitation is used by the nurses to optimize their role in improving patient health and telerehabilitation will answer the problem of penetrating the distance dimension.

Rehabilitation agency of older adults in group-based intervention

AIMS

This study investigated the individual rehabilitation agency of older adults in a one-year group-based gerontological rehabilitation context. Here, rehabilitation agency is understood as being manifested when older adults make choices and decisions regarding their everyday lives, including notions of themselves.

METHODS

The data were obtained via non-participant observation of the final individual goal evaluation sessions of 38 older adults with their personal counselor. In these sessions, older adults discussed their rehabilitation outcomes, actions, choices and decisions during the rehabilitation year, along with their future in home settings. The data were analyzed using qualitative content analysis and an agency-centred approach.

FINDINGS

The findings revealed that older adults made choices and decisions differently concerning their life in and beyond the rehabilitation context. Four forms of rehabilitation agency of older adults were identified: (i) renewable, (ii) widened, (iii) selective and (iv) fractured. These forms of agency were differently connected to older adults' life courses and to their peer relations in the rehabilitation context.

CONCLUSIONS

An agency-centred approach could produce new theoretical ideas and practical implications for developing older adults' rehabilitation to better meet their needs as well as the goals of group-based rehabilitation interventions.

Virtual reality for stroke rehabilitation

BACKGROUND

Virtual reality and interactive video gaming have emerged as recent treatment approaches in stroke rehabilitation with commercial gaming consoles in particular, being rapidly adopted in clinical settings. This is an update of a Cochrane Review published first in 2011 and then again in 2015.

OBJECTIVES

Primary objective: to determine the efficacy of virtual reality compared with an alternative intervention or no intervention on upper limb function and activity.Secondary objectives: to determine the efficacy of virtual reality compared with an alternative intervention or no intervention on: gait and balance, global motor function, cognitive function, activity limitation, participation restriction, quality of life, and adverse events.

SEARCH METHODS

We searched the Cochrane Stroke Group Trials Register (April 2017), CENTRAL, MEDLINE, Embase, and seven additional databases. We also searched trials registries and reference lists.

SELECTION CRITERIA

Randomised and quasi-randomised trials of virtual reality ("an advanced form of human-computer interface that allows the user to 'interact' with and become 'immersed' in a computer-generated environment in a naturalistic fashion") in adults after stroke. The primary outcome of interest was upper limb function and activity. Secondary outcomes included gait and balance and global motor function.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials based on pre-defined inclusion criteria, extracted data, and assessed risk of bias. A third review author moderated disagreements when required. The review authors contacted investigators to obtain missing information.

MAIN RESULTS

We included 72 trials that involved 2470 participants. This review includes 35 new studies in addition to the studies included in the previous version of this review. Study sample sizes were generally small and interventions varied in terms of both the goals of treatment and the virtual reality devices used. The risk of bias present in many studies was unclear due to poor reporting. Thus, while there are a large number of randomised controlled trials, the evidence remains mostly low quality when rated using the GRADE system. Control groups usually received no intervention or therapy based on a standard-care approach.

PRIMARY OUTCOME

results were not statistically significant for upper limb function (standardised mean difference (SMD) 0.07, 95% confidence intervals (CI) -0.05 to 0.20, 22 studies, 1038 participants, low-quality evidence) when comparing virtual reality to conventional therapy. However, when virtual reality was used in addition to usual care (providing a higher dose of therapy for those in the intervention group) there was a statistically significant difference between groups (SMD 0.49, 0.21 to 0.77, 10 studies, 210 participants, low-quality evidence).

SECONDARY OUTCOMES

when compared to conventional therapy approaches there were no statistically significant effects for gait speed or balance. Results were statistically significant for the activities of daily living (ADL) outcome (SMD 0.25, 95% CI 0.06 to 0.43, 10 studies, 466 participants, moderate-quality evidence); however, we were unable to pool results for cognitive function, participation restriction, or quality of life. Twenty-three studies reported that they monitored for adverse events; across these studies there were few adverse events and those reported were relatively mild.

AUTHORS' CONCLUSIONS

We found evidence that the use of virtual reality and interactive video gaming was not more beneficial than conventional therapy approaches in improving upper limb function. Virtual reality may be beneficial in improving upper limb function and activities of daily living function when used as an adjunct to usual care (to increase overall therapy time). There was insufficient evidence to reach conclusions about the effect of virtual reality and interactive video gaming on gait speed, balance, participation, or quality of life. This review found that time since onset of stroke, severity of impairment, and the type of device (commercial or customised) were not strong influencers of outcome. There was a trend suggesting that higher dose (more than 15 hours of total intervention) was preferable as were customised virtual reality programs; however, these findings were not statistically significant.
