The Impact

BACKGROUND Virtual reality (VR) training is a promising intervention strategy, which has been utilized in healthcare fields like stroke rehabilitation and psychotherapy. The current study suggests that, VR training is effective in improving the locomotor ability of individuals with stroke patients. OBJECTIVE This is the first meta-meta-analysis of the effects of virtual reality on motor function in stroke patients. This study aimed to systematically summarize and quantify the present meta-analyses results of VR training, and produce high-quality meta-meta-analysis results to obtain a more accurate prediction. METHODS We searched four online databases (Web of Science, Scopus, PubMed, and Chinese National Knowledge Infrastructure) for the meta-analysis studies. After accounting for the overlap, ten studies (almost 550 stroke patients) were obtained. Based on the meta-meta-analysis of these patients, this study quantified the impact of VR training on stroke patients’ motor performance, mainly including upper limb function, balance, and walking ability. We combined the effects under the random effect model and pooled the estimates as standardized mean differences (SMD). RESULTS The results of the meta-meta analysis showed that VR intervention effectively improved the upper limb function (SMD= 4.606, 95% confidence interval (Cl): 2.733-6.479, P< 0.05) and balance (SMD=2.101, 95%Cl：0.202-4.000, P< 0.05) of stroke patients. However, the results showed considerable heterogeneity, and thus, may need to be treated with caution. Due to the limited research, the meta-meta-analysis of walking ability was not performed. CONCLUSIONS These findings represent a comprehensive body of high-quality evidence that, VR interventions were more effective at improving the upper limb function and balance of stroke patients.

Objective. The aim of this study was to perform a meta-analysis to examine whether virtual reality (VR) training is effective for lower limb function as well as upper limb and overall function in chronic stroke patients. Methods. Three databases, OVID, PubMed, and EMBASE, were used to collect articles. The search terms used were “cerebrovascular accident (CVA),” “stroke”, and “virtual reality”. Consequently, twenty-one studies were selected in the second screening of meta-analyses. The PEDro scale was used to assess the quality of the selected studies. Results. The total effect size for VR rehabilitation programs was 0.440. The effect size for upper limb function was 0.431, for lower limb function it was 0.424, and for overall function it was 0.545. The effects of VR programs on specific outcomes were most effective for improving muscle tension, followed by muscle strength, activities of daily living (ADL), joint range of motion, gait, balance, and kinematics. Conclusion. The VR training was effective in improving the function in chronic stroke patients, corresponding to a moderate effect size. Moreover, VR training showed a similar effect for improving lower limb function as it did for upper limb function.

Abstract Background: Impaired cognitive ability to anticipate the required control may affect functional recovery. The cortical excitability of task related motor anticipation for upper limb movement induced by virtual reality (VR) training is unknown. Aims: To investigate the changes of motor anticipation, cortical excitability and upper limb function induced by VR training in subacute stroke survivors. Methods: Upper limb hemiparesis resulting from the first occurrence of stroke within 1 to 6 months were recruited. Participants were randomly allocated to conventional therapy or VR intervention. Electroencephalogram (EEG) and electromyography (EMG) were simultaneously recorded during palmar grasp motion. Outcome measures of contingent negative variation (CNV) latency, mean peak amplitude, electromyography (EMG) reaction time, Upper Limb Fugl-Meyer Assessment (UL-FMA) and the Action Research Arm Test (ARAT) were recorded pre and post intervention. The EEG and EMG differences between the two groups were assessed by mixed model ANOVA (p=0.05). The differences in UL-FMA and ARAT were assessed Wilcoxon signed-rank test (p=0.05). Results: The reduction in EMG reaction time difference, CNV latency and mean peak amplitude were significantly lower in the VR group than the control group when executing movement with the paretic hand. ARAT and UL-FMA scores were significantly higher in the VR group than the control group post intervention. Conclusions: The findings indicated a reduction in brain computational demand during palmar grasp task. Improvements in clinical function in the VR group suggested that VR intervention may be more beneficial in improving upper limb function patients with subacute stroke. Improvement in upper limb function may be related to improvement of the neural anticipatory process. Trial registration: Chinese Clinical Trial Registry (Registration No.: ChiCTR-IOC-15006064).
