The objective of this study was to discern the effects of a balance training program on the performance of lower extremities in order to improve strength (muscle power, flexibility, walking power), balance control and walking ability in the elderly. The subjects selected were aged 65 years and over, with no known relevant medical history that may disturb their balance, and have also been visiting the Gimhae Senior Welfare Center. The variable group consisted of 30 subjects, of whom were people who had been participating in balance training programs (One Leg Standing; OLS, Functional Reach; FR, Timed Get Up and Go; TUG) as an intervention for 8 weeks 3 times per a week. They were examined in order to identify their balance control before and after. The control group consisted of thirty subjects who preferred to exercise without any intervention relating to balance training program. The subjects were measured before and after balance training in order to determine the effectiveness of exercise and the effectiveness of exercise combined with the aid of a Balance Performance Monitor. 1. Mean time on OLS test with left and right sided extremities in the experimental group was 35.44 sec, 42.10 sec longer than control group respectively. In FR tests applied to the left and right side, mean reaching distance was increased up to 5.56 cm, 6.73 cm in experimental group respectively. Mean time on TUG test from a chair in experimental group was decreased to 2.33 sec. 2. Mean value of decline in the level balance control, both left and right side, decreased to 2.24% as examined by the Balance Performance Monitor. Mean scores for sway level after balance training decrease to .98% and for balance control both anterior and posterior directions decreased to mean 1.07% and 1.44%, respectively.

The purpose of this study was to assess the effect of visual block (eyes open or closed), mental task type, and participation in an exercise program on static balance in the elderly. The subjects were 34 elderly (>65 years old) residents of a social welfare institute in Gyeonggi-do. We measured the following variables. Berg balance scale, mini mental state examination, balance performance monitor (sway area, path, and maximal sway velocity), age, weight, height and whether the subject participated in an exercise program. Scores for the Berg balance scale and mini mental state examination were evaluated to assess static balance ability either alone (single task paradigm) or while performing a mental task (dual task paradigm). Static balance variables that were measured included sway area, path, and maximal sway velocity. Each test was repeated three times. Multiple regressions analysis was used to examine the effect of each variable on static balance ability. For the dual task paradigm, static balance was affected by whether the subject participated in an exercise program. The Berg balance scale score for subjects with their eyes open was affected by whether they participated in an exercise program, while this variable in addition to the height and weight of subjects were determining variables in subjects with their eyes closed. As a result, whether subjects participated in an exercise program affected their static balance irrespective of whether their eyes open or closed. Therefore, regular exercise is recommended for elderly people and further research is needed to examine the relationship between static and dynamic balance while performing mental tasks such as cognition and attention.

Purpose: We investigate to evaluate the effects of scapular stabilization exercise on dynamic standing balance in stroke patients. Methods: Thirty hemiplegic patients participated was divided into control group and training group randomly. Control group(n=15) had only general rehabilitation training and training group (n=15) had both the general rehabilitation training and intensive scapular stabilization exercise. They were treated for 15minute/5 times/4 week. We measured PALM (palpation meter) to measure affected side's distances from spine to scapular. We measured FRT (functional reach test), FSST (four squared step test), and BPM (balance performance monitering) to evaluate dynamic standing balance. Results: Training group showed a significant difference in the distances from spine to scapular, FRT, FSST, and variables of BPM comparing control group (p<0.05). But control group was not significant difference. Conclusion: These results suggest that scapular stabilization exercises have positive effects on dynamic standing position.

Purpose: The aim of the present study was to understand the relationship between gait symmetry and functional balance, walking performance in stroke patients and to makes recommendation regarding the most suitable measure for standardization of expression of spatiotemporal gait symmetry. Methods: 45 subjects with stroke (31 men, 14 women, $57.3{\pm}10.3$ years old) participated in this study. Gait symmetry was calculated by equations of symmetry ratio (SR) and symmetry criterion (SC) for stance time, swing time, single leg support time (SLST), step length, and stride length. Spatiotemporal parameters were measured respectively by walkway system ($GAITRite^{TM}$ system). Limit of stability (LOS) by using forceplate (Balance Performance Monitor) during voluntary weight displacement and Berg Balance Scale (BBS) were measured as functional balance and Timed Up and Go test (TUG) and Functional Ambulation Category (FAC) were assessed as functional walking. Results: SR in stance time and swing time was correlation with BBS, TUG and FAC (p<0.05). SR in SLST only with BBS (p<0.01), SR in step length only with FAC (p<0.05). SC in stance time was correlation with BBS and TUG (p<0.05). SC in swing time and SLST with BBS, TUG and FAC (p<0.01), SC in step length with TUG and FAC (p<0.01), SC in stride length with BBS and FAC (p<0.01). Conclusion: Gait symmetry in spatiotemporal gait parameters provides meaningful information about functional balance and walking performance in stroke subjects. Our analysis may support the recommendations of the symmetry criterion as equation for standardization of gait symmetry.
