Background: Previous robot-mediated gait training has been proven several limitations such as pointless repeated motion training, decreased presence, etc. In this research, adult stroke patients were participated in robot-mediated gait training accompanied with or without virtual reality program. Objectives: Exploring whether the results indicated virtual reality system has contribution to muscle strength and balance ability. Design: A case series research, cross-over trial. Methods: Eleven participants (male 4, female 7) with adults diagnosed as stroke from medical doctor ware engaged. The participants received 2 treatment sessions of identical duration, robot-assisted gait training with virtual reality and robot-assisted gait training with screen-off randomly crossed over include 1-day for each person of wash-out period. The parameter was muscle activity, the researchers assessed sEMG (surface electromyography). Results: The result showed less muscle activities during training in robot-assisted gait training with virtual reality circumstances, and these indicated muscles were gluteus medius muscle, vastus medialis muscle, vastus intermedius and vastus lateralis muscle, semimembranosus muscle, gastrocnemius-lateral head, and soleus muscle (P<.05). Conclusion: In this study, we analyzed the outcome of muscle activity for clinical inference of robot-assisted gait training with virtual reality (VR). Less muscle activity was measured in the treatment accompanied by VR, therefore, a more systematic, in-depth and well-founded level of follow-up research is needed.

Purpose: In this study, we investigated the effectiveness of a 12-week virtual reality exercise program using the Nintendo Wii console (Wii) in improving balance, emotion, and quality of life among patients with cognitive decline. Methods: The study included 30 patients with cognitive decline (12 female, 18 male) who were randomly assigned to an experimental (n=15) and control groups (n=15). All subjects performed a traditional cognitive rehabilitation program and the experimental group performed additional three 40-minute virtual reality based video game (Wii) sessions per week for 12 weeks. The berg balance scale (BBS) was used to assess balance abilities. The short form geriatric depression scale-Korean (GDS-K) and the Korean version of quality of life-Alzheimer's disease (KQOL-AD) scale were both used to assess life quality in patients. Statistical significance was tested within and between groups before and after treatment, using Wilcoxon signed rank and Mann-Whitney u-tests. Results: After 36 training sessions, there were significant beneficial effects of the virtual reality game exercise on balance (BBS), GDS-K, and KQOL-AD in the experimental group when compared to the control group. No significant difference was observed within the control group. Conclusion: These findings demonstrate that a virtual reality-training program could improve the outcomes in terms of balance, depression, and quality of life in patients with cognitive decline. Long-term follow-ups and further studies of more efficient virtual reality training programs are needed.

Objective: This study aimed to investigate the upper limb strength, active joint range of motion (AROM), and upper limb function in persons with chronic stroke using virtual reality training in combination with upper limb sensory stimulation. Design: Two-group pretest-posttest design. Methods: 20 subjects were divided into two groups of 10, the sensory motor stimulation and virtual reality training (SMVR) and virtual reality training (VR) groups. The training was conducted for 30 minutes per session, three times a week for 8 weeks.The participants' upper limb strength was measured via the hand-held dynamometer, joint angle AROM was measured via dual inclinometer, function was measured using the Jebson-Taylor hand function test and the manual function test. Results: Significant differences were observed in all groups before and after the training for upper extremity strength, AROM, and function (p<0.05). Between the two groups, the SMVR group showed significant improvement in muscle strength, AROM, and Jebsen-Taylor hand function test scores compared with the VR groups (p<0.05). Conclusions: In this study, we confirmed that sensory stimulation and VR had positive effects on upper extremity strength, AROM, and function of persons with chronic stroke. The results suggest that in the future, VR in combination with sensory stimulation of the upper limb is likely to become an effective method (a rehabilitation training program) to improve the upper limb function of persons with chronic stroke.
