The purposes of this study was to determine the effects of limited hyperextension at knee joint using Limited Motion Knee Brace on balance and walking in patients with hemiplegia. The subjects of this study were 20 post-stroke hemiplegic patients admitted. Subjects were randomly assigned to either experimental group (Limited Motion Knee Brace group) or control group (manual restriction group). Both groups received traditional physical therapy intervention. The effects of each therapeutic method were evaluated by measurements of gait ability assesment, Berg balance scale (BBS), 10-meter walk speed (10MWS), Timed Up & Go (TUG) Test. The results of this research were as followings: (1) After treatment, there were significant BBS scores differences in both experimental and control group compared with pre-treatment(p<0.05). (2) After treatment, there were significant TUG test scores differences in both experimental and control group compared with pre-treatment (p<0.05). (3) After treatment, there were significant 10MWS differences in both experimental and control group compared with pre-treatment (p<0.05). (4) There were significant BBS scores differences in third and fourth week between experimental and control group (p<0.05). It was concluded that Limited Motion Knee Brace was effective for improving balance and for reducing fatigue for experimental group. Therefore, further studies are required to investigate the effect of knee orthosis for improving balance and walking in patients with hemiplegia.

The purpose of this study was to examine the effects of whole-body vibration exercise for life care on balance and walking ability in the fall risk stroke patients. 30 stroke patients were divided into two groups, Otago exercise group(n=15) and whole-body vibration exercise group(n=15). Walking ability were measured by 10m walking and Tinetti mobility test with stroke patients and balance ability were measured by BBS and TUG on comparative analysis of pre, post exercise. To compare differences before and after the program, a paired t-test was used and to compare differences between both groups, an independent samples t-test was used. As a result of the test, it was discovered that BBS and Tinetti mobility test of the both groups were increased statistically significantly and TUG and 10m walking test of the both groups were decreased statistically significantly. balance ability and walking ability of the whole-body vibration exercise group were improved statistically significantly in comparison with those of the Otago exercise group. The results of this study showed that whole-body vibration exercise for the improvement of life care had significant effects on improving BBS, TUG, 10m walking and Tinetti mobility test of fall risk stroke patients. Therefore, it is recommended to apply whole-body vibration exercise to improve life-care through improving balance ability and walking ability of fall risk stroke patients.

Age related decrease of muscle strength, balance, and gait abilities bring about physical inactivity in the elderly. Virtual reality (VR) training has been used successfully to rehabilitate functional balance and mobility in elderly subjects. This study was aimed at determining the effect of VR-based exercise programs by using a video game on the muscle strength, balance, and gait abilities in the elderly. 48 old people were randomly divided into two groups; VR-group (men: 11, women: 14, age: 68.42yrs) and control group (men: 10, women: 13, age: 67.58yrs). VR-group performed an exercise program twice a week for 8 weeks and control group had no intervention. The VR-based exercise program was composed of warm up(10 mins), VR-program(40 mins), and cool down(10mins). It was performed by playstation eyetoy play that provided visual and auditory feedback as well as movements of the upper and lower extremities. Muscle strengths of the knee and ankle were measured using manual muscle tester. Static balance was estimated using computerized posturography. Dynamic balance was measured by Timed up and go test (TUG), Functional reach test (FRT). 10m walk test and 6-min walk test were used to assess gait abilities. After the completion of the VR-exercise program, muscle strength, balance, and gait abilities were improved significantly (p<0.05). In conclusion, the VR-based exercise program showed improvement on the muscle strength, balance, and gait ability in the elderly. This exercise program is both effective and interesting for this age group.

This study studied the effect of visual difference on balance and walking ability in college students' life care. The study was conducted on 45 students attending H University in G City, divided into control groups (n=22, not wearing glasses and contact lenses) and experimental groups (n=23, wearing glasses and contact lenses). In not wearing glasses and contact lenses, the subjects measured visual acuity with logMAR charts, evaluated their balance ability with BIOrescue, and evaluated walking ability with G-Walk. The results of this study showed that the experimental group had statistically significantly lower vision than the control group in the visual acuity measurement(p<.01). Static balance ability was statistically significant increase in center of mass movement of the right foot in the experimental group compared to the control group(p<.05). Dynamic balance ability was statistically significantly reduce in limit of stability for groups of experiments compared to control group(p<.05). The walking ability was statistically significantly shorter on step length and stride length, swing of the experimental group compared to the control group in the right foot(p<.05). The findings showed that the visual difference in university students reduces balance and walking ability. Therefore, university students with poor visual acuity are recommended to correct of visual acuity to prevent collision and falls in their daily lives.

The purpose of this study was to improve the gait ability and quality of life of stroke patients by combining virtual reality technology and a visual feedback gait training program with entertainment elements. Ten stroke patients with circumduction gait were selected. The visual feedback treadmill gait training program using virtual reality technology and a force plate measurement system was conducted 30 minutes a day, 5 days a week, with 25 sessions in 5 weeks. To investigate the effects of this gait training program, evaluations using the joint range-of-motion test, muscle activity tests, Berg balance scale (BBS), gait analysis, and stroke-specific quality-of-life scale (SS-QOL) were performed before and after intervention. Statistically significant differences were found in the joint range of motion and muscle activity of the affected side from the initial swing phase to the mid-swing phase of the gait cycle, dynamic balance, gait function, and quality of life (p <0.05). The results of this study indicate that the gait training program improved the foot drop, muscle activity, dynamic balance, and gait ability of stroke patients with circumduction gait, thereby improving the quality of life of the patients. Therefore, we recommend the application of the visual feedback treadmill gait training program using virtual reality technology and a force plate measurement system to improve gait ability and quality of life of stroke patients with circumduction gait.

This study is for the elderly with mental and physical dysfunction, developing resistance exercise program using tube elasticity, and analysing the effects of this movement on the improvement of gait ability, balance ability and muscle strength of the elderly. After a 12-week program for 58 participants of the daycare center, dependent t-test was performed. As a result, the total participants showed average improvement in gait, balancing and hand grip strength. This means a lot in terms of improving one's ability of ADL(Activities of daily living) and reducing the risk of falling. Therefore, if the program expands and activates the target as an entire elderly, it is expected to be a preventative way to prevent healthy elderly people from moving to the frailty who need treatment and to delay the deterioration of the frailty with disabilities.
