PURPOSE: The purpose of this study was to investigate the effect of balance training on different support surface (affected and non-affected sides) on the balance and gait function of chronic stroke patients. METHODS: The patients were randomly assigned to 1 of 4 groups. Group 1 received balance training on the stable surface, group 2 received balance training on the unstable surface, group 3 received balance training on different support surface (affected side: stable surface, non-affected side: unstable surface), and group 4 received balance training on different support surface (affected side: unstable, non-affected side: stable). Twelve sessions (30 min/d, 3 times/wk for 4 wk) were applied. There were assessed before and after the intervention with Balancia, functional reach test (FRT), lateral reach test (LRT), timed up-and-go (TUG), and 10-meter walking test (10MWT). RESULTS: After the training, all of the groups improved significantly than before training in Balancia, FRT, LRT, TUG, and 10MWT. There were significantly variable in sway distance, FRT, LRT, TUG, and 10MWT among the 4 groups. Post hoc analysis revealed that the group 3 had significantly higher results than other 3 groups in sway distance, and FRT, LRT, TUG, and 10MWT. CONCLUSION: Balance training on different support surface (affected side: stable surface, non-affected side: unstable surface) could facilitate a stronger beneficial effect on balance and walking ability than other balance trainings on different support surface in patients with stroke.
Purpose: The purpose of this study was to investigate the effect of a kettlebell complex program according to the support surface on the lower extremity muscle activity and balance of baseball players. Methods: The participants were divided into two groups; unstable support surface group 1 (11 people) performed the kettlebell complex program on an unstable support surface, and stable support surface group 2 (10 people) performed the kettlebell complex program on a stable support surface. Muscle activity was measured by surface electromyography. Dynamic balance was measured with a balance-measuring equipment. A paired t-test was used to compare groups before and after the experiment. An independent t-test was performed to determine the difference in the degree of change between the two groups before and after the experiment. Results: The intragroup comparison between stable support surface group 1 and 2 showed significant differences in muscle activity and sense of balance. In the comparison between the groups, the difference in muscle activity in unstable support surface group1 was significant in the biceps femoris and rectus femoris muscles, and significant differences were also found in the sense of balance. Conclusion: These results suggest that a kettlebell exercise on an unstable support surface is more effective in improving muscle activity and sense of balance than a kettlebell exercise on a stable support surface.
A decrease in the ability to maintain static and dynamic balance after stroke could be related to the inability to select reliable sensory information in producing relative motor action needed to maintain postural stability. The purpose of this study was to compare the effects of two different types of surface conditions on the balancing ability of subjects with stroke. Eighteen hemiparetic subjects were assigned to an experimental and control group participating in a six-week rehabilitative therapeutic exercise program focusing on balance and mobility. Exercises were performed 3 to 5 times per week in a stable surface condition by the control group, and in an unstable surface condition by the experimental group. Pre- and post test assessments involved the measurement of the static balance and dynamic balance, respectively by 7-item Berg Balance Scale-3P and by Pro-3 Balance System. Results showed that under the unstable surface condition, static balance in the experimental group showed more improvement than that of the control group.(Statistically, not very significant.) All the aspects of dynamic balance and mediolateral sway(balance) improved significantly than those of the control group. However, there were no significant differences between two groups. Overall, it can be concluded that under the unstable surface condition, the rehabilitative therapeutic exercise programs are effective in improving the dynamic balance of stroke subjects. The results suggest that the adaptation of the unstable surface in the rehabilitative therapeutic exercises could be effective for the patients with hemiplegia in balance. Further studies are needed to confirm the effectiveness of the unstable surface on improving balance and postural stability of hemiplegics.

Background: Functional ankle instability (FAI) indicating a decrease in muscle strength, proprioception, neuromuscular control, balance and postural control function. Objective: To investigate the effect of jumping exercise on the supporting surface on the ankle muscle thickness, proprioceptive sensation, and balance in adults with FAI. Design: Randomized Controlled Trial. Methods: Twenty young people with FAI were randomly assigned to the unstable supporting surface jump group (N=10) and the stable supporting surface jump group (N=10). The intervention was conducted three times a week for eight weeks, and for 30 minutes per session. Trampoline was used as an unstable support surface and the stable support surface was carried out on a regular floor. The thickness of the tibialis anterior muscle and medial gastrocnemius muscle was measured by ultrasonography, and the proprioception of dorsiflexion and plantarflexion was measured using an electrogoniometer. The dynamic balance was also measured with a balance meter. Results: The the muscle thickness of the medial gastrocnemius muscle was significantly higher in the stable supporting surface jump group than in the unstable supporting surface jump group (p<.05). Furthermore, the plantar flexion proprioception and dynamic balance were significantly improved in the unstable supporting surface jump group than in the stable supporting surface jump group in the intergroup comparison (p<.05). Conclusions: The conclusion has been reached in this study that the jumping exercise on the unstable supporting surface could be a more effective in improving FAI than the regular surface.

Purpose : The purpose of this study is balanced exercise program according to the supporting surface any affect women's ability to balance high heels. Methods : This study subjects were normal 20 females in their twenties. They were divided into stable supporting surface(n=10), unstable supporting surface(n=10), and they exercised three times a week for 5 weeks. In order to compare the difference of balance, the subjects were measured before and after training. Balance was examined using the balance master 7.0 version systems. Results : 1. There was significant difference values between pre-exercise and post-exercise of unstable surface group on the FORM-EO and FORM EC of MCTSIB and all of Unilateral Stance variables. 2. There was significant difference values between pre-exercise and post-exercise of stable surface group on the mean EPE, mean MXE, and mean DCL of LOS. 3. There was significant difference values between pre-exercise and post-exercise of unstable surface group of the rhythmic weight shift. 4. There was significant difference value in the slow directional control of rhythmic weight shift between groups after exercise. Conclusion : Training on stable supporting surface group and unstable supporting surface group improve balance.

Purpose : The purpose of this study was to compare the effects of ankle balance training on unstable and stable surfaces to discover on which surface the proprioception, balance and muscle strength of obese middle aged women improves more. Method : Thirty obese middle-aged women were randomly recruited and divided into two groups (training on an unstable surface, training on a stable surface). The subjects in each group participated in the training for six weeks, three times per week for 30 minutes each session. Proprioception was measured using Dualer IQ digital inclinometer; sway length (SL) and sway area (SA) of center of pressure, and limit of stability (LOS) were measured for balance; muscle strength before and after the training was measured using manual muscle testing. Results : There were significant improvements in the subscales of the proprioception, balance and muscle strength in those who participated in ankle balance training on the unstable surface, and in those who participated on the stable surface. However, before and after the intervention, there were no differences between those who had the balance traning on the unstable surface and those who had the balance traning on the stable surface. Conclusion : Unstable and stable surface ankle balance training are both effective in improving the proprioception, balance and muscle strength of obese middle-aged woman.

Purpose : The purpose of this study was to demonstrate the effects of lumbar stabilization exercise on static and dynamic balance performance with unstable supporting surface and an even surface. Methods : The subjects of this experimental study were 30 patients among hospitalized stroke patients. They were randomly divided into two groups: unstable supporting surface group(USS; n=15) and an even surface group(ES; n=15). The lumbar stabilization exercise program for patients in two groups went through 40 minute exercise sessions three times a week for 8 weeks. To analyze the effects of a variety of supporting surface, Functional reaching test(FRT), Berg's balance scale(BBS), and Overall stability index(static balance) were measured before and after the exercise. The paired t-test was used to compare mean differences between before and after exercis and the independent t-test was used to compare mean differences between groups. Results : After 8 weeks exercise program, there were significant differences between before and after exercise in FRT, BBS, and static balance. But there were not significant differences in balance between two groups. Conclusion : This study suggest that lumbar stabilization exercise on unstable supporting surface and an even surface can improve FRT, BBS, and a static balance.
Purpose: The purpose of this study was to examine the muscle activity of the trunk muscles during balance exercises on a stable and unstable surface in patients with stroke. Methods: Thirteen subjects (8 males, 5 females) with stroke were enrolled in the study. Muscle activity was recorded using surface EMG electrodes from the affected side of the erector spinae, external oblique, and internal oblique muscles. The exercise was performed under three conditions. For the first condition for balance exercise, subjects were instructed to sit on an exercise mat with legs extended. The second condition was to sit with legs extended, with a balance pad under their buttocks. The third condition was to sit with legs extended, have a balance pad under the buttocks and a balance cushion under the lower legs. Results: This study showed significant differences in EMG activities during both arm lifting exercise and weight shifting exercise between conditions. This study showed that the EMG activities of the erector spinae, external oblique, and internal oblique muscles were significantly higher when the trunk exercise was performed using the balance pad with balance ball than when using the stable surface. Conclusion: In conclusion, performing balance exercises using an unstable surface is a useful method for facilitating trunk-muscle strength and hence trunk stability.

PURPOSE: The purpose of this study was to compare task-oriented balance training on stable and unstable surfaces in terms of the fall risk, balance, and gait abilities in patients with stroke. METHODS: Twenty patients with stroke were divided randomly into a stable surface group (SSG, N=10) or unstable surface group (USG, N=10). The participants in the SSG and USG performed task-oriented balance training on stable and unstable surfaces, respectively. All participants were evaluated using the Tetrax, Berg balance scale (BBS), and 10-meter walking test (10MWT) before and after the intervention. Both groups received training 30 min per day, five times per week, for six weeks. RESULTS: The within-group changes in the fall risk, BBS, and 10MWT were significantly different in both USG and SSG (p<.05). USG showed significantly more improvement in the BBS and 10MWT compared to SSG (p<.05). CONCLUSION: Task-oriented balance training on an unstable surface is more beneficial in improving the balance and gait abilities of stroke patients.
