The Pediatric Balance Scale (PBS) was balance measurement equipment for school-age children with mild to moderate motor impairments. The aims of this study are to examine the correlation between PBS and spatiotemporal gait parameter and to identify the walking function with cerebral palsy through balance scale. The PBS consists of 14 items such as sitting of standing, standing to sitting, transfers, standing unsupported, standing on one foot, turning 360 degrees, turing to look behind, etc., and the spatiotemporal parameters include walking speed, stride length, step length, step width, cadence, double-limb support. All subjects were independently ambulatory children with spastic diplegic cerebral palsy, and they were assessed on PBS and spatiotemporal gait parameters by an experienced pediatric physical therapist. Pearson's correlation coefficient was used to assess the correlation between PBS and spatiotemporal gait parameters, and the level of significance was set at ${\alpha}$ = 0.05. Total score of PBS(r=.49~.58), standing to sitting(r=.48~.60), turning to look behind(r=.47~.53), and pick up object(r=.52~.69) were positively correlated with walking speed, stride length, step length, and cadence. Most items of the PBS were negatively correlated with double-limb support(r=-.48~-.92). These findings suggest that the pediatric balance scale can be applied to estimate gait function level for children with spastic diplegic cerebral palsy.

Purpose: This study was conducted to find out the immediate effect on dynamic balance through Abdominal hollowing exercise and Abdominal bracing exercise. Method: 90 healthy male and female students in their 20s were surveyed and measured using Y-balance test and Functional reach test. Result: In the dynamic balance Test between groups, there was a statistically significant difference between the group that performed Abdominal hollowing exercise and the control group. Conclusion: Although both representative spinal stabilization exercises Abdominal hollowing exercise and Abdominal bracing exercise are meaningful in increasing dynamic equilibrium, it is difficult to suggest that any method is more effective in terms of immediate effects.

This study was to investigate the balancing and clinical abilities using stable and unstable surface of stroke patients who surface changes in balance of body. The subjects of this study were 30 stroke patients(16 males and 14 females). They were separated into two groups and did balance reinforcing exercise on stable and unstable surfaces for five times a week for six weeks. To evaluate their balancing ability, they performed functional standing balance test, functional forward arm stretching test. performance-oriented mobility assessment was performed. The balancing exercises were modified from preceding studies and consisted of 6 difference exercises. The functional standing test with open and close eyes and performance-oriented mobility assessment, the unstable surface exercise group and the stable surface exercise group improved significantly. The forward arm stretching test was the unstable surface exercise group improved. This study found that the balancing exercise on unstable surface was more effective than on stable surface for stroke patients. Thus, exercise on unstable surface has more positive effects on the improvement of balancing abilities of stroke patients.

The purpose of this study was to determine the effect of mechanical horseback riding training on trunk control, balance function in stroke patients. 15 stroke patients were recruited for this study. The subjects were randomly assigned to two groups: experimental(n=7) and control(n=8). All subjects received a routine physical therapy. The mechanical horseback riding training was for 30 min in the case of the EG subjects. This study was carried out approximately 8 weeks from March 4 to May 3. The assessment tools of this study involved the trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test. The measurements were recorded before the intervention and after the intervention. In the cases of the EG subjects and CG subjects, the variables measured after the intervention significantly differed from trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test before the intervention (p<.05). Also, there were significant differences in trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test at post test between the 2 groups (p<.05). The findings indicate that mechanical horseback riding training exerts a positive effect on trunk control, balance function in stroke patients. Further studies are required to generalize the result of this study.

This study aimed to examine the changes in dynamic balance exercises after performing lunge exercises on unstable surfaces and on the ground. Participants were divided into a BOSU training group, a balance pad training group, and a ground training group, and performed lunge exercises. As a result, the functional reach test significantly increased in both the BOSU training group and the ground training group, while the Y-balance test significantly increased only in the balance pad training group. No significant differences were found between the groups. Through this study, it was confirmed that although differences between lunge exercises on the ground and on unstable surfaces were not identified, lunge exercises do influence balance ability.
