Objective: This study investigated the effect of a video game-based home exercise program on the improvement of balance and muscle strength in the elderly. Design: Randomized controlled trial Methods: Participants were randomly assigned to two groups: a video game-based home exercise training group (experimental group, n=16) and a control group (n=17). The experimental group trained three times a week for 50 minutes per session for six weeks, and the control group did not perform any exercise. To evaluate postural balance, one leg standing test, Berg balance scale, functional reach test, and timed up and go test were performed, and five times sit-to-stand was performed to evaluate lower extremity muscle strength. Results: In the experimental group, there were statistically significant improvements (p<0.05) in one leg standing test, Berg balance scale, functional reach test, and timed up and go test, and five times sit-to-stand after the intervention, but in the control group, the difference before and after the intervention was not significant. The difference between the groups according to the experimental method showed a significant increase in the experimental group (p<0.05). Conclusions: These results suggest that a video game-based home exercise program effectively improves balance and muscle strength in the elderly. A video game-based exercise program can contribute to the rehabilitation of the elderly as a method of home remote rehabilitation.

The purpose of this study is to investigate the effect of visual rhythmic stimulation in gait ability and proprioception in chronic stroke patients. Twenty-one persons after six months post stroke participated in pre and post test control. The subjects were randomly assigned to a rhythmic visual stimulation(RVS) group (n=10) and control group (n=11). Training process was practiced with exercise on thirty minutes a day, three days a week for four weeks. To find out the effect, inspected the proprioception test and gait characteristics by gait analysis. In gait characteristics, the walking speed, cadence and the TUG time were significantly different from RVS group. The proprioception were significantly different RVS and control group. This study showed that the RVS training increased better functional activity by postural adjustment and gait learning of chronic stroke patients than that of control group. And so, the RVS training of hemiplegic patients was very important to successive rehabilitation. A continuous examination of RVS training could be practical use of physical therapy with exercise.

The purpose of this study was to investigate the effect of stability on one leg standing posture in yoga practice. Thirteen women college student who have never done yoga participated in this study. In order to collect data before and after yoga practicing for two years, we were used 3D motion capture system and electromyography. The results were as follows. First, ranges of motions for Y axis of left knee joint and X axis of right ankle joint were significantly different in dancer posture(p<.05), and then X axis of right ankle and Y axis of left ankle joint were significantly different in tree posture of pre and post training. Second, the planar alignment angle of trunk-pelvis was not significant difference in dancer and tree posture. Third, CoM-distances of Y, Z directions were significant difference in the tree posture(p<.05). Fourth, Muscle activities of both rectus abdominis, erector spinae and left quadriceps were significant difference in tree posture(p<.05). These findings suggested that yoga training played important roles in stable postures as results of decreasing rotation ankle joint and movement of CoM and enforcing core muscles. This study provides evidence for effectiveness of the stability on standing posture and can get a great effect on posture correction by means of yoga training. Hereafter, study on alignment angle, which is a measurement of postural stabilization will be needed by future yoga training.

In this paper, a new rehabilitation training system was developed to improve equilibrium sense by combining virtual reality technology with a fixed exercise bicycle. The subjects consisted of two groups. A group of young people, was compared against a group of elderly. We measured three different running modes of virtual bicycle system with two successive sets. The parameters measured were running time, velocity, the weight movement, the degree of the deviation from the road, and the variables about the center of pressure. The repeated training, our results showed that the running capability of the elderly improve compared. In addition, it was found out that the ability of postural control and the equilibrium sense was improved with the presentation of the visual feedback information of the distribution of weight. From the results of this experiment, we showed that our newly developed system might be useful in the diagnosis of equilibrium sense or in the improvement of the sense of sight and, somatic, and vestibular sense of the elderly in the field of rehabilitation training.

The purpose of this study was to examine the effects of coordinative locomotor training (CLT) program on the balance for the promotion of life care of elderly obese women. Ten participants of elderly obese women who were able to walk independently without surgery experience of lumbar, hip or knee joint within the past year were recruited and under went the pretest, CLT (20 sessions), followed by the post-test. The test included BMI test using In-body, joint kinematics using myoVIDEO, muscle activation using surface EMG test (erector spinae (ER), external oblique abdominalis (EO), quadriceps femoris (Quad), hamstring muscle (Ham)) and balance tests including dynamic balance test using forced treadmill, Berg balance scale (BBS) and timed up go (TUG). The CLT program was conducted 60 minutes a day, 5 days a week, over 4 weeks period. As a result of this study, The the trunk and hip joints kinematics during the stance and swing phases of gait were a statistical significance levels were set at p <0.05. The ER and EO muscle activation were significantly improved after intervention (p <0.05). The length of gait line and single support line of change of center of pressure (COP) were significantly increased after intervention (p <0.05). The BBS and TUG were also significantly enhanced after intervention (p <0.05). The results of this study showed that CLT program for the improvement of life care had significant effects on improving postural instability, muscle weakness, reduced balance ability and falling risk of obese elderly women. Therefore, it is recommended to apply CLT program to improve life-care through improving balance ability and preventing fall of obese elderly women.

Objective: The purpose of this study was to investigate the effects rhythmic and non-rhythmic aerobic exercises on depression and balance of healthy elderly people. Design: Randomized controled trial. Methods: Nineteen older subjects were randomly divided into 2 groups for rhythmic and non-rhythmic aerobic exercises. Both aerobic exercises consisted of functional movements such as turning in opposite directions, and running in place, the exercise consisted of movements that could activate balance. The rhythmic training group initially used music with 8 beats, and then later progressed to 16 beats. Additionally, we adjusted the pace of the music using songs from 125 beats per minute (bpm) to 160 bpm. Both groups were exercised for 50 minutes a day, twice a week, for a total of 8 weeks. We measured the condition of the patients before the intervention, and after 8 weeks of intervention. The Beck depression inventory (BDI) was used to measure the degree of depression. The Berg balance scale (BBS) was used to measure static and dynamic balance ability. We measured the subject's subjective balance confidence using the fall efficacy scale (FES). Results: Both groups showed significant improvement in BDI, BBS, and FES (p<0.05). The rhythmic aerobic exercise group showed a significant improvement only in the BBS change values compared to the non-rhythmic group (p<0.05). Conclusions: According to this study, both rhythmic and non-rhythmic aerobic exercises resulted in significant improvement in the degree of depression and balance ability of the elderly. The rhythmic aerobic exercise was more effective for dynamic balance ability.

PURPOSE: The aim of the present study was to determine whether high frequency repetitive transcranial magnetic stimulation (rTMS) can improve balance ability in acute stage stroke patients. METHODS: The study was conducted on 30 subjects diagnosed with hemiparesis caused by stroke. The experimental group consisted of 15 patients that underwent rTMS for 15 mins and the control group consisted of 15 patients that underwent sham rTMS (for 15 minutes). A 70-mm figure 8 coil and a Magstim Rapid stimulator was used in both groups. Patients in the experimental group received 10 Hz rTMS applied to the hotspot in the lesioned hemisphere in 10-second trains with 50-second intervals between trains, for 15 minutes (total 2,000 pulses). Both groups received conventional physical therapy for 30 minutes a day, 5 days a week, for 4 weeks. Static balance ability analysis was performed using the Gaitview system to measure pressure rate, postural sway, and total pressure, and dynamic balance ability analysis was performed to measure pressure variables using a balance system. RESULTS: A significant difference was observed in post-training gains for pressure rate, total pressure in static balance, and overall stability index in dynamic balance between the experimental group and the control group (p<.05). CONCLUSION: The results of this study indicate that high frequency rTMS may be beneficial for improving static and dynamic balance recovery in acute stroke patients.
