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.

Conventional Mirror Therapy versus Immersive Virtual Reality Mirror Therapy: The Perceived Usability after Stroke

Background

Stroke is a widespread and complex health issue, with many survivors requiring long-term rehabilitation due to upper-limb impairment. This study is aimed at comparing the perceived usability of two feedback-based stroke therapies: conventional mirror therapy (MT) and immersive virtual reality mirror therapy (VR).

Methods

The study involved 45 participants, divided into three groups: the stroke survivors (n = 15), stroke-free older adults (n = 15), and young controls (n = 15). Participants performed two tasks using both MT and VR in a semirandom sequence. Usability instruments (SUS and NASA-TLX) were applied at the end of the activities, along with two experience-related questions.

Results

The results indicated that both MT and VR had similar levels of perceived usability, with MT being more adaptable and causing less overall discomfort. Conversely, VR increased the perception of task difficulty and prevented participants from diverting their attention from the mirror-based feedback.

Conclusion

While VR was found to be less comfortable than MT, both systems exhibited similar perceived usability. The comfort levels of the goggles may play a crucial role in determining the usability of VR for upper limb rehabilitation after stroke.

Effectiveness of Mechanical Horse-Riding Simulator-Based Interventions in Patients with Cerebral Palsy-A Systematic Review and Meta-Analysis

BACKGROUND

Mechanical horse-riding simulator (HRS) exercises are a type of therapy based on the use of robotic or mechanical devices that produces movement similar to a real horse with the aim of simulating hippotherapy. This review analyses the effectiveness of HRS therapies in patients with cerebral palsy (CP).

METHODS

A systematic review and a meta-analysis were carried out by searching studies in PubMed Medline, SCOPUS, Web of Science, CINAHL, PEDro and SciELO up until October 2022. We selected clinical trials that assessed the effectiveness of HRS therapy, compared to other interventions, in patients with CP. The main variables were gross motor function (its global score and dimensions, such as sitting ability), functional balance, spasticity, hip range of motion (ROM), posturographic balance and satisfaction. The risk of bias was assessed using the Cochrane Risk of Bias Tool. The pooled effect was calculated using Cohen's Standardized Mean Difference (SMD) for a 95% confidence interval (95% CI).

RESULTS

Twelve studies were included in the systematic review, and 10 were included in the meta-analysis, providing data from 343 patients with spastic diplegic CP. Our findings revealed that HRS plus physiotherapy is more effective than physiotherapy in improving the total gross motor function (SMD 0.98; 95% CI 0.35-1.62), sitting ability of the gross motor function (SMD 0.84; 95% CI 0.32-1.36) and functional balance (SMD 0.6; 95% CI 0.1-1.08), and HRS therapy is better than sham to improve pelvic abduction ROM (SMD 0.79; 95% CI 0.21-1.37).

CONCLUSIONS

Horse-riding simulator-based therapy is an effective therapy to improve gross motor function, functional balance and abduction pelvic ROM in children with CP, in comparison to physiotherapy or sham.

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.

Cadence Feedback and Video-Based Engagement Improves Motivation and Performance during Pedalling in Stroke Patients

Video and music as a dissociative attention stimulus during exercise is known to distract from the discomfort of physical exertion and improve exercise adherence; however, the influence of video-based feedback and engagement during pedalling on the performance and motivation of pedalling in stroke patients is poorly understood. The aim of this study was to employ a novel video-based engagement paradigm for pedalling in stroke patients and evaluate its capacity to influence the cadence control, physiological output, and perceived motivation and enjoyment. Thirteen stroke patients were recruited with low-to-moderate lower-limb disability (mean age: 64.0 yrs.). A reference group of 18 healthy young adult subjects (mean age: 27.7 yrs.) was also recruited to assess the broad applicability of the techniques to a contrasting non-pathological cohort. The participants pedalled at a slow (60 RPM) and fast (100 RPM) target speed with constant resistance in 15 min pedalling bouts that included (i) baseline pedalling with real-time visual feedback of cadence deviation from the target provided only in the first 20 s (ii) real-time visual feedback of cadence data over the entire pedalling session, and (iii) real-time engagement to maintain the playback rate of a prerecorded video by pedalling at the target speed. During low speed pedalling, stroke patients demonstrated significantly smaller absolute cadence deviation during pedalling with feedback (mean difference: 1.8 RPM, p = 0.014) and video-based engagement (mean difference: 2.4 RPM, p = 0.006) compared to the baseline pedalling. For the healthy adults, feedback and video-based engagement reduced cadence deviation significantly at all speeds (p < 0.05). All but one stroke patient either enjoyed or really enjoyed the video engagement during pedalling and felt motivated to undertake this form of exercise in therapy in the future. This proof-of-concept study showed that feedback and video-based engagement may improve the targeted pedalling performance in stroke patients, and by helping dissociate subjects from physical cues associated with fatigue, may ultimately improve exercise motivation and compliance.

Motor Rehabilitation of Upper Limbs Using a Gesture-Based Serious Game: Evaluation of Usability and User Experience

Objective: Gesture-based serious games can be based on playful and interactive scenarios to enhance user engagement and experience during exercises, thereby increasing efficiency in the motor rehabilitation process. This study aimed to develop the Rehabilite Game (RG) as a complementary therapy tool for upper limb rehabilitation in clinics and home environments and to evaluate aspects of usability and user experience of it. Materials and Methods: The evaluation consisted of the use of a gesture-based serious game with motor rehabilitation sessions managed in a web platform. Thirty-three participants were recruited (21 physiotherapists and 12 patients). The protocol allowed each participant to have the experience of playing sessions with different combinations of settings. The User Experience Questionnaire (UEQ) was used to evaluate aspects of usability and user experience. The study was approved by the Research Ethics Board of the Federal University of Piaui (number 3,429,494). Results: The level of satisfaction with the RG was positive, with an excellent Net Promoter Score for 85.7% of physiotherapists and 100% of patients. All six UEQ scales (attractiveness, perspicuity, efficiency, dependability, stimulation, and novelty) reflected acceptance. Conclusion: The study demonstrated that, according to the results obtained in the experiments, the RG had positive feedback from physiotherapists and patients, indicating that the game can be used in a clinical trial to be compared with other rehabilitation techniques.

Occupational Therapy and the IMPACT Act: Part 2. A Systematic Review of Evidence for Functional Status, Medication Reconciliation, and Skin Integrity Interventions

IMPORTANCE

Interventions that promote function, medication reconciliation, and skin integrity assist occupational therapy practitioners in demonstrating professional value, improving quality, and reducing health care costs.

OBJECTIVE

In this systematic review, we focus on three outcome areas of the Improving Medicare Post-Acute Care Transformation (IMPACT) Act of 2014: functional status, medication reconciliation, and skin integrity.

DATA SOURCES

We conducted a search of the literature published between 2009 and 2019 in CINAHL, Cochrane, MEDLINE, PsycINFO, OTseeker, and Scopus. We also hand searched the systematic reviews and meta-analyses in our search results for articles that met our inclusion criteria. Study Selection and Data Collection: This study used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

FINDINGS

We found 47 articles that address the three outcome areas. Regarding functional status, low strength of evidence is available for cognition and functional mobility interventions to support functional performance, moderate strength of evidence supports interventions for vision, and moderate evidence supports task-oriented and individualized interventions to promote activities of daily living (ADL) outcomes among people with neurological conditions. Strong strength of evidence supports individualized occupational therapy interventions focusing on medication adherence. Low strength of evidence was found for occupational therapy interventions to reduce pressure ulcers and promote skin integrity. Conclusion and Relevance: The evidence supports occupational therapy interventions to improve functional status in ADLs and medication management. Additional research is needed that examines the outcomes of occupational therapy interventions for other areas of function and skin integrity. What This Article Adds: We found evidence to support occupational therapy interventions that align with value-based measures in the three outcome areas of interest. The effectiveness of these interventions highlights the viability of occupational therapy as an essential profession and the worth of occupational therapy to the public, potential clients, and payers.

Identifying key elements to assess patient's acceptability of neurorehabilitation in stroke survivors - a Delphi method

PURPOSE

Assessing patient acceptability of treatment is a clinical concern. No guidance exists to determine the best way to measure acceptability in stroke neurorehabilitation. This study identifies key elements to measure patient's acceptance of stroke neurorehabilitation by establishing expert consensus.

MATERIALS AND METHODS

A four-phase Delphi method with a three-round electronic-based survey was conducted. Experts were considered as stroke survivors or their caregivers and professionals in stroke neurorehabilitation. A twenty-five-item list was sourced from a literature review and discussion with a consumer panel (n = 22). In Round-1 (n = 118) and Round-2 (n = 80), experts ranked the items on a five-point scale. Consensus levels were validated by a Validation group in Round-3 (n = 50). Validity of the results was considered if consensus reached ≥70%, a non-bimodal pattern of response central tendency, SD in Round-2 was lower than that in Round-1, and the agreement scores of responses were similar between all rounds.

RESULTS

In Round-1&2 and Round-3, 77.5% (n = 62) and 74.0% (n = 37) respectively, of the respondents were professionals, 20.0% (n = 16, n = 10 respectively) were either stroke survivors or caregivers, and 2.57% (n = 2) and 6.0% (n = 3) respectively were professionals who themselves were stroke survivors or caregivers. The key elements which met all priori criteria are: Goal setting, Measurable progress, Functional improvement, Challenging, Motivation, Interactive, Communications with health professionals, Knowledge of treatment, and No risks.

CONCLUSIONS

Patient's acceptance is crucial to developing the appropriate neurorehabilitation interventions. Future clinical trials should consider these items when measuring patient's acceptance of stroke neurorehabilitation interventions during the development and evaluation phases.Implications for rehabilitationAssessing patient acceptability of treatment is a clinical concern in stroke neurorehabilitation.This study has identified nine key elements to assess patient acceptability of stroke neurorehabilitation. These key elements are: Goal setting, Measurable progress, Functional improvement, Challenging, Motivation, Interactive, Communications with health professionals, Knowledge of treatment, and No risks.Professionals should consider these elements when measuring patient's acceptance of an intervention during the development, piloting, evaluation, and implementation phases.These findings provide a framework in designing neurorehabilitation programs and clinical trials on acceptance of and adherence to treatment in stroke survivors.

Commercial videogames in stroke rehabilitation: systematic review and meta-analysis

Objective: The aim of this article was to perform a systematic review of all studies (both observational and experimental) wherein commercial video games were used in comprehensive rehabilitation (both physical and cognitive areas) after stroke.Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed, and all observational and experimental studies that met at least six PEDro scale criteria were included. A total of 50 studies were included in the Meta-Analysis. Data analysis was performed using RevMan 5.3 and the bias with JAMOVI.Results: In observational studies, results favored intervention with video games in terms of functionality such as Fulg-Meyer Assessment scores [standard mean difference (SMD) = -0.45; 95% CI = -0.74 to -0.15; p = .94; I2 = 0%)] and when measured in the upper limbs using the Wolf Motor Function Test (SMD = 0.41; 95% CI = 0.07 to 0.74; p = .47; I2 = 0%). Other results showed heterogeneity. In the experimental group, most results tended to favor the experimental group and showed homogeneity, but they were not significant. Fail Safe N was calculated, and the results were not biased.Conclusions: Results tend to favor intervention with commercial video games, but the heterogeneity of the measuring instruments and small sample size do not allow for significant results to be obtained. Future research should provide the number of participants, mean, and standard deviation to facilitate future meta-analyses. Commercial video games appear to be a feasible tool in physical and cognitive stroke rehabilitation.

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.

Effectiveness of Nintendo Wii and Physical Therapy in Functionality, Balance, and Daily Activities in Chronic Stroke Patients

OBJECTIVES

The aim of this study was to assess whether a virtual rehabilitation program using Nintendo Wii added to conventional physical therapy improved functionality, balance, and daily activities in chronic stroke survivors, when compared with conventional physical therapy.

DESIGN

We undertook a randomized controlled clinical trial. The participants of this study were randomized to 2 groups: (1) conventional physical therapy (CPTG), which included exercises related to functionality, balance, and activities of daily living; and (2) virtual reality with Nintendo Wii (VRWiiG), which included balance training with the Wii Balance Board and upper limb exercises with the Wii Sports package, added to conventional physical therapy.

SETTING AND PARTICIPANTS

This study was conducted in a university rehabilitation clinic and 29 stroke survivors were admitted.

METHODS

Both interventions lasted 4 weeks, 2 sessions per week. Assessments were performed at baseline and at the end of the study, including functionality [Timed up and go (TUG)], balance [Tinetti Performance-Oriented Mobility Assessment (POMA)], Berg Balance Scale (BBS), and activities of daily living [Fugl-Meyer Upper Limb Motor Assessment, Barthel Index, Frenchay Activity Index (FAI)].

RESULTS

Regarding TUG, POMA, and BBS, the analysis of variance showed significant differences for time and group∗time interaction. Post hoc analysis showed between-group differences (P = .044, d = -0.78; P = .012, d = 1.00; P = .042, d = 0.79, respectively) and within-group differences only in the VRWiiG (P < .001, d = 0.75; P < .001, d = -0.76; P < .001, d = -0.57, respectively). Regarding activities of daily living, post hoc analysis showed within-group differences only in VRWiiG.

CONCLUSIONS AND IMPLICATIONS

Our study showed promising results in functionality, balance, and activities of daily living when adding virtual reality with Nintendo Wii to conventional physical therapy in chronic stroke survivors. All procedures were approved by the Human Research Ethics Committee of the University of Valencia (H1518177391901). ClinicalTrials.gov database (NLM identifier NCT04144556).

What is the impact of user affect on motor learning in virtual environments after stroke? A scoping review

PURPOSE

The purported affective impact of virtual reality (VR) and active video gaming (AVG) systems is a key marketing strategy underlying their use in stroke rehabilitation, yet little is known as to how affective constructs are measured or linked to intervention outcomes. The purpose of this scoping review is to 1) explore how motivation, enjoyment, engagement, immersion and presence are measured or described in VR/AVG interventions for patients with stroke; 2) identify directional relationships between these constructs; and 3) evaluate their impact on motor learning outcomes.

METHODS

A literature search was undertaken of VR/AVG interventional studies for adults post-stroke published in Medline, PEDro and CINAHL databases between 2007 and 2017. Following screening, reviewers used an iterative charting framework to extract data about construct measurement and description. A numerical and thematic analytical approach adhered to established scoping review guidelines.

RESULTS

One hundred fifty-five studies were included in the review. Although the majority (89%; N = 138) of studies described at least one of the five constructs within their text, construct measurement took place in only 32% (N = 50) of studies. The most frequently described construct was motivation (79%, N = 123) while the most frequently measured construct was enjoyment (27%, N = 42). A summative content analysis of the 50 studies in which a construct was measured revealed that constructs were described either as a rationale for the use of VR/AVGs in rehabilitation (76%, N = 38) or as an explanation for intervention results (56%, N = 29). 38 (76%) of the studies proposed relational links between two or more constructs and/or between any construct and motor learning. No study used statistical analyses to examine these links.

CONCLUSIONS

Results indicate a clear discrepancy between the theoretical importance of affective constructs within VR/AVG interventions and actual construct measurement. Standardized terminology and outcome measures are required to better understand how enjoyment, engagement, motivation, immersion and presence contribute individually or in interaction to VR/AVG intervention effectiveness.

Effects of Exergame on Patients' Balance and Upper Limb Motor Function after Stroke: A Randomized Controlled Trial

BACKGROUND

Stroke is a major cause of motor incapacity in adults and the elderly population, requiring effective interventions capable of contributing to rehabilitation. Different interventions such as use of exergames are being adopted in the motor rehabilitation and balance area, as they act as motivating instruments, making therapies more pleasurable.

OBJECTIVE

The aim of this study was to investigate the effects of exergame on patients' balance and upper limb motor function after stroke.

METHODS

This study is a randomized controlled trial. Thirty-one participants of both genders, mean age of 76 years, were assigned to the experimental or control groups; the experimental group (n = 16) underwent exergame rehabilitation using Motion Rehab AVE 3D, and the control group (n = 15) underwent conventional physiotherapy. Both EG and GC sessions happened twice a week, for 30 minutes each, over a 12 weeks period, resulting in 24 sessions. All sessions were composed of similar exercises, with same purpose and elapsed time (5 minutes). Instruments applied to verify inclusion criteria were a sociodemographic questionnaire and clinical aspects and a Mini-Mental State Examination. At baseline and after 12 weeks of intervention, the Modified Ashworth Scale, the Fugl-Meyer Assessment, and the Berg Balance Scale were used.

RESULTS

In both groups, patients obtained significant improvement from baseline values in all analyzed variables (shoulder, elbow, and forearm; wrist; hand; and balance) (P < .001). In the intergroup comparison, there were significant differences between the 2 groups for changes in values from preintervention to postintervention of shoulder, elbow and forearm (P = .001), and total (P = .002).

CONCLUSION

Exergame rehabilitation in poststroke patients can be an efficient alternative for restoring balance and upper limb motor function and might even reduce treatment time.

Meta-analyzability Concerns in Meta-analyses

Many studies to date have conducted a meta-analysis on a mix of effectiveness and superiority studies. This methodological flaw will lead to difficulties in interpreting the results. We addressed this issue in this article, illustrated our point with a simulated experiment, and re-analyzed a recent meta-analysis study based on the effectiveness-superiority dichotomy to provide a real-world correlate of our point of view.

A Game Changer: 'The Use of Digital Technologies in the Management of Upper Limb Rehabilitation'

Hemiparesis is a symptom of residual weakness in half of the body, including the upper extremity, which affects the majority of post stroke survivors. Upper limb function is essential for daily life and reduction in movements can lead to tremendous decline in quality of life and independence. Current treatments, such as physiotherapy, aim to improve motor functions, however due to increasing NHS pressure, growing recognition on mental health, and close scrutiny on disease spending there is an urgent need for new approaches to be developed rapidly and sufficient resources devoted to stroke disease. Fortunately, a range of digital technologies has led to revived rehabilitation techniques in captivating and stimulating environments. To gain further insight, a meta-analysis literature search was carried out using the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) method. Articles were categorized and pooled into the following groups; pro/anti/neutral for the use of digital technology. Additionally, most literature is rationalised by quantitative and qualitative findings. Findings displayed, the majority of the inclusive literature is supportive of the use of digital technologies in the rehabilitation of upper extremity following stroke. Overall, the review highlights a wide understanding and promise directed into introducing devices into a clinical setting. Analysis of all four categories; (1) Digital Technology, (2) Virtual Reality, (3) Robotics and (4) Leap Motion displayed varying qualities both-pro and negative across each device. Prevailing developments on use of these technologies highlights an evolutionary and revolutionary step into utilizing digital technologies for rehabilitation purposes due to the vast functional gains and engagement levels experienced by patients. The influx of more commercialised and accessible devices could alter stroke recovery further with initial recommendations for combination therapy utilizing conventional and digital resources.

Patient and therapist experiences of using affordable feedback-based technology in rehabilitation: a qualitative study nested in a randomized controlled trial

Objective:

To explore how technologies are used and experienced in rehabilitation.

Design:

A qualitative study using a grounded theory approach within a randomized controlled trial investigating the effectiveness of tailored, affordable technologies to improve mobility and physical activity.

Settings:

Aged care and neurological rehabilitation wards with community follow-up.

Participants:

Twenty patients undergoing rehabilitation and randomized to the experimental arm of a trial (mean age 64 years (SD 23)) were recruited for interviews, plus 11 physiotherapists involved in technology prescription as part of the trial.

Method:

Two interviews per patient (one in hospital, one post-discharge) and four focus groups with physiotherapists were conducted. Transcribed data were coded and synthesized. Memo-writing and constant comparison methods guided data analysis.

Results:

A process of patient engagement with technology involving two stages: (1) initial patient engagement and (2) maintaining patient engagement was identified. Therapists used a series of steps and strategies to gain and maintain patient engagement. A positive first experience and continued input into patient programmes was needed. The level of patient engagement was not consistent across the duration of the trial, increasing or decreasing due to changes in the technologies prescribed or setting of use. Two conditions were key to optimizing patient engagement: sufficient support and perceived benefit from using technology.

Conclusions:

Patients can engage with technology during rehabilitation when prescription is tailored by a therapist. Perceiving benefit from using technology, in addition to receiving the right support to enable use appears to influence the level of patient engagement.

Usability evaluation of low-cost virtual reality hand and arm rehabilitation games

The emergence of lower-cost motion tracking devices enables home-based virtual reality rehabilitation activities and increased accessibility to patients. Currently, little documentation on patients' expectations for virtual reality rehabilitation is available. This study surveyed 10 people with stroke for their expectations of virtual reality rehabilitation games. This study also evaluated the usability of three lower-cost virtual reality rehabilitation games using a survey and House of Quality analysis. The games (kitchen, archery, and puzzle) were developed in the laboratory to encourage coordinated finger and arm movements. Lower-cost motion tracking devices, the P5 Glove and Microsoft Kinect, were used to record the movements. People with stroke were found to desire motivating and easy-to-use games with clinical insights and encouragement from therapists. The House of Quality analysis revealed that the games should be improved by obtaining evidence for clinical effectiveness, including clinical feedback regarding improving functional abilities, adapting the games to the user's changing functional ability, and improving usability of the motion-tracking devices. This study reports the expectations of people with stroke for rehabilitation games and usability analysis that can help guide development of future games.

What do randomized controlled trials say about virtual rehabilitation in stroke? A systematic literature review and meta-analysis of upper-limb and cognitive outcomes

BACKGROUND

Virtual-reality based rehabilitation (VR) shows potential as an engaging and effective way to improve upper-limb function and cognitive abilities following a stroke. However, an updated synthesis of the literature is needed to capture growth in recent research and address gaps in our understanding of factors that may optimize training parameters and treatment effects.

METHODS

Published randomized controlled trials comparing VR to conventional therapy were retrieved from seven electronic databases. Treatment effects (Hedge's g) were estimated using a random effects model, with motor and functional outcomes between different protocols compared at the Body Structure/Function, Activity, and Participation levels of the International Classification of Functioning.

RESULTS

Thirty-three studies were identified, including 971 participants (492 VR participants). VR produced small to medium overall effects (g = 0.46; 95% CI: 0.33-0.59, p < 0.01), above and beyond conventional therapies. Small to medium effects were observed on Body Structure/Function (g = 0.41; 95% CI: 0.28-0.55; p < 0.01) and Activity outcomes (g = 0.47; 95% CI: 0.34-0.60, p < 0.01), while Participation outcomes failed to reach significance (g = 0.38; 95% CI: -0.29-1.04, p = 0.27). Superior benefits for Body Structure/Function (g = 0.56) and Activity outcomes (g = 0.62) were observed when examining outcomes only from purpose-designed VR systems. Preliminary results (k = 4) suggested small to medium effects for cognitive outcomes (g = 0.41; 95% CI: 0.28-0.55; p < 0.01). Moderator analysis found no advantage for higher doses of VR, massed practice training schedules, or greater time since injury.

CONCLUSION

VR can effect significant gains on Body Structure/Function and Activity level outcomes, including improvements in cognitive function, for individuals who have sustained a stroke. The evidence supports the use of VR as an adjunct for stroke rehabilitation, with effectiveness evident for a variety of platforms, training parameters, and stages of recovery.

Mobile Game-based Virtual Reality Program for Upper Extremity Stroke Rehabilitation

Stroke rehabilitation requires repetitive, intensive, goal-oriented therapy. Virtual reality (VR) has the potential to satisfy these requirements. Game-based therapy can promote patients' engagement in rehabilitation therapy as a more interesting and a motivating tool. Mobile devices such as smartphones and tablet PCs can provide personalized home-based therapy with interactive communication between patients and clinicians. In this study, a mobile VR upper extremity rehabilitation program using game applications was developed. The findings from the study show that the mobile game-based VR program effectively promotes upper extremity recovery in patients with stroke. In addition, patients completed two weeks of treatment using the program without adverse effects and were generally satisfied with the program. This mobile game-based VR upper extremity rehabilitation program can substitute for some parts of the conventional therapy that are delivered one-on-one by an occupational therapist. This time-efficient, easy to implement, and clinically effective program would be a good candidate tool for tele-rehabilitation for upper extremity recovery in patients with stroke. Patients and therapists can collaborate remotely through these e-health rehabilitation programs while reducing economic and social costs.

Mobile game-based virtual reality rehabilitation program for upper limb dysfunction after ischemic stroke

BACKGROUND

Virtual reality (VR) has the potential to provide intensive, repetitive, and task-oriented training, and game-based therapy can enhance patients' motivation and enjoyment.

OBJECTIVE

The objective of the present study was to develop a mobile game-based upper extremity VR program for patients who have experienced stroke, and to evaluate the feasibility and effectiveness of the program.

METHODS

This randomized, double-blind, controlled trial included 24 patients with ischemic stroke. The intervention group (n = 12) received 30 min of conventional occupational therapy (OT) and 30 min of the mobile upper extremity rehabilitation program using a smartphone and a tablet PC (MoU-Rehab). The controls (n = 12) received conventional OT alone for 1 h per day. Rehabilitation consisted of 10 sessions of therapy, 5 days per week, for 2 weeks. The outcome measures (Fugl-Meyer Assessment of the upper extremity [FMA-UE], Brunnström stage [B-stage] for the arm and the hand, manual muscle testing [MMT], modified Barthel index [MBI], EuroQol-5 Dimension [EQ-5D], and Beck Depression Inventory [BDI]) were assessed at the beginning and end of treatment, and at 1 month. User satisfaction was evaluated by a questionnaire.

RESULTS

A greater improvement in the FMA-UE, B-stage, and MMT was found after treatment with the MoU-Rehab than with conventional therapy. The extent of improvements in the MBI, EQ-5D, and BDI was not significantly different between the two groups. Patients in the experimental group completed the 2-weeks treatment without adverse effects, and they were generally satisfied with MoU-Rehab.

CONCLUSION

This mobile game-based VR rehabilitation program appears to be feasible and effective for promoting upper limb recovery after ischemic stroke.

Usability Test of Exercise Games Designed for Rehabilitation of Elderly Patients After Hip Replacement Surgery: Pilot Study

BACKGROUND

Patients who receive rehabilitation after hip replacement surgery are shown to have increased muscle strength and better functional performance. However, traditional physiotherapy is often tedious and leads to poor adherence. Exercise games, provide ways for increasing the engagement of elderly patients and increase the uptake of rehabilitation exercises.

OBJECTIVE

The objective of this study was to evaluate Fietsgame (Dutch for cycling game), which translates existing rehabilitation exercises into fun exercise games. The system connects exercise games with a patient's personal record and a therapist interface by an Internet of Things server. Thus, both the patient and physiotherapist can monitor the patient's medical status.

METHODS

This paper describes a pilot study that evaluates the usability of the Fietsgame. The study was conducted in a rehabilitation center with 9 participants, including 2 physiotherapists and 7 patients. The patients were asked to play 6 exercise games, each lasting about 5 min, under the guidance of a physiotherapist. The mean age of the patients was 74.57 years (standard deviation [SD] 8.28); all the patients were in the recovery process after hip surgery. Surveys were developed to quantitatively measure the usability factors, including presence, enjoyment, pain, exertion, and technology acceptance. Comments on advantages and suggested improvements of our game system provided by the physiotherapists and patients were summarized and their implications were discussed.

RESULTS

The results showed that after successfully playing the games, 75% to 100% of the patients experienced high levels of enjoyment in all the games except the squats game. Patients reported the highest level of exertion in squats when compared with other exercise games. Lunges resulted in the highest dropout rate (43%) due to interference with the Kinect v2 from support chairs. All the patients (100%) found the game system useful and easy to use, felt that it would be a useful tool in their further rehabilitation, and expressed that they would like to use the game in the future. The therapists indicated that the exercise games highly meet the criteria of motor rehabilitation, and they intend to continue using the game as part of their rehabilitation treatment of patients. Comments from the patients and physiotherapists suggest that real-time corrective feedback when patients perform the exercises wrongly and a more personalized user interface with options for increasing or decreasing cognitive load are needed.

CONCLUSIONS

The results suggest that Fietsgame can be used as an alternative tool to traditional motor rehabilitation for patients with hip surgery. Lunges and squats are found to be more beneficial for patients who have relatively better balance skills. A follow-up randomized controlled study will be conducted to test the effectiveness of the Fietsgame to investigate how motivating it is over a longer period of time.

Reported use of technology in stroke rehabilitation by physical and occupational therapists

PURPOSE

With the patient care experience being a healthcare priority, it is concerning that patients with stroke reported boredom and a desire for greater fostering of autonomy, when evaluating their rehabilitation experience. Technology has the potential to reduce these shortcomings by engaging patients through entertainment and objective feedback. Providing objective feedback has resulted in improved outcomes and may assist the patient in learning how to self-manage rehabilitation. Our goal was to examine the extent to which physical and occupational therapists use technology in clinical stroke rehabilitation home exercise programs.

MATERIALS AND METHODS

Surveys were sent via mail, email and online postings to over 500 therapists, 107 responded.

RESULTS

Conventional equipment such as stopwatches are more frequently used compared to newer technology like Wii and Kinect games. Still, less than 25% of therapists' report using a stopwatch five or more times per week. Notably, feedback to patients is based upon objective data less than 50% of the time by most therapists. At the end of clinical rehabilitation, patients typically receive a written home exercise program and non-technological equipment, like theraband and/or theraputty to continue rehabilitation efforts independently.

CONCLUSIONS

The use of technology is not pervasive in the continuum of stroke rehabilitation. Implications for Rehabilitation The patient care experience is a priority in healthcare, so when patients report feeling bored and desiring greater fostering of autonomy in stroke rehabilitation, it is troubling. Research examining the use of technology has shown positive results for improving motor performance and engaging patients through entertainment and use of objective feedback. Physical and occupational therapists do not widely use technology in stroke rehabilitation. Therapists should consider using technology in stroke rehabilitation to better meet the needs of the patient.

The use of commercial video games in rehabilitation: a systematic review

The aim of this paper was to investigate the effect of commercial video games (VGs) in physical rehabilitation of motor functions. Several databases were screened (Medline, SAGE Journals Online, and ScienceDirect) using combinations of the following free-text terms: commercial games, video games, exergames, serious gaming, rehabilitation games, PlayStation, Nintendo, Wii, Wii Fit, Xbox, and Kinect. The search was limited to peer-reviewed English journals. The beginning of the search time frame was not restricted and the end of the search time frame was 31 December 2015. Only randomized controlled trial, cohort, and observational studies evaluating the effect of VGs on physical rehabilitation were included in the review. A total of 4728 abstracts were screened, 275 were fully reviewed, and 126 papers were eventually included. The following information was extracted from the selected studies: device type, number and type of patients, intervention, and main outcomes. The integration of VGs into physical rehabilitation has been tested for various pathological conditions, including stroke, cerebral palsy, Parkinson's disease, balance training, weight loss, and aging. There was large variability in the protocols used (e.g. number of sessions, intervention duration, outcome measures, and sample size). The results of this review show that in most cases, the introduction of VG training in physical rehabilitation offered similar results as conventional therapy. Therefore, VGs could be added as an adjunct treatment in rehabilitation for various pathologies to stimulate patient motivation. VGs could also be used at home to maintain rehabilitation benefits.

Cognitive Remediation for the Treatment of Cognitive Dysfunction in the Early Course of Psychosis

The development of cognitive remediation programs has been a key step toward the creation of a treatment approach to address the cognitive-symptom domain in psychosis. Studies support the efficacy of cognitive remediation in producing moderate effects on cognition at the group level in patients with schizophrenia. Cognitive remediation may harness neuroplasticity in relevant systems that underpin the cognitive functions being addressed. Since neuroplasticity may be greater in people who (1) are younger and (2) have not yet experienced the consequences of long-term psychosis, cognitive remediation may be particularly effective in people in the early course of illness or in the prodrome, prior to the onset of frank symptoms. The present article reviews the evidence for implementing cognitive remediation in patients with recent-onset psychosis and people identified as being at high risk for developing schizophrenia, and also the evidence for cognitive remediation to modify neural targets. Promising findings suggest that cognitive remediation may be useful in addressing cognitive deficits in early-course and prodromal participants. Additionally, a growing literature using neuroimaging techniques demonstrates the ability of cognitive remediation paradigms to engage neural targets.

Coaching or gaming? Implications of strategy choice for home based stroke rehabilitation

Background

The enduring aging of the world population and prospective increase of age-related chronic diseases urge the implementation of new models for healthcare delivery. One strategy relies on ICT (Information and Communications Technology) home-based solutions allowing clients to pursue their treatments without institutionalization. Stroke survivors are a particular population that could strongly benefit from such solutions, but is not yet clear what the best approach is for bringing forth an adequate and sustainable usage of home-based rehabilitation systems. Here we explore two possible approaches: coaching and gaming.

Methods

We performed trials with 20 healthy participants and 5 chronic stroke survivors to study and compare execution of an elbow flexion and extension task when performed within a coaching mode that provides encouragement or within a gaming mode. For each mode we analyzed compliance, arm movement kinematics and task scores. In addition, we assessed the usability and acceptance of the proposed modes through a customized self-report questionnaire.

Results

In the healthy participants sample, 13/20 preferred the gaming mode and rated it as being significantly more fun (p < .05), but the feedback delivered by the coaching mode was subjectively perceived as being more useful (p < .01). In addition, the activity level (number of repetitions and total movement of the end effector) was significantly higher (p < .001) during coaching. However, the quality of movements was superior in gaming with a trend towards shorter movement duration (p = .074), significantly shorter travel distance (p < .001), higher movement efficiency (p < .001) and higher performance scores (p < .001). Stroke survivors also showed a trend towards higher activity levels in coaching, but with more movement quality during gaming. Finally, both training modes showed overall high acceptance.

Conclusions

Gaming led to higher enjoyment and increased quality in movement execution in healthy participants. However, we observed that game mechanics strongly determined user behavior and limited activity levels. In contrast, coaching generated higher activity levels. Hence, the purpose of treatment and profile of end-users has to be considered when deciding on the most adequate approach for home based stroke rehabilitation.
