본 논문은 뇌졸중 환자를 대상으로 그들의 균형능력을 평가하여 낙상의 위험을 예견하기 위하여 임상에서 가장 보편적으로 사용되고 있는 버그균형척도와 균형 및 평형능력을 평가하기 위하여 사용되는 Smart Balance Master System의 평형지수 사이의 상관관계를 알아보기 위함이었다. 22명의 만성 뇌졸중 환자가 본 연구에 참여하였다. 조용하고 잘 정돈된 치료실에서 대상자에게 버그균형척도와 Smart Balance Master System을 실시하였다. 연구결과 버그균형척도와 Smart Balance Master System의 평형지수는 중등도 이상의 유의한 상관관계를 보여주었다. 또한 Smart Balance Master System의 6가지 조건에서 모든 '눈 감고 지지면 동요 조건'에서 유의한 상관성이 없었으며, 다른 5가지 조건과는 중등도 이상의 유의한 상관성을 보여주었다. 뇌졸중 환자는 균형능력을 유지하기 위하여 시각에 대한 의존도가 높으며, 버그균형척도가 이런 부분을 적절히 평가하지 못하기 때문에 '눈 감고 지지면 동요 조건'과 유의한 상관성을 보여주지 못한 것으로 사료된다. 따라서 임상에서 뇌졸중 환자를 대상으로 그들의 낙상을 예견하기 위해서는 한 가지 이상의 임상 평가방법을 사용하여 감각기관의 모든 영향을 고려하는 것이 그들의 낙상 위험을 예견하는데 보다 적절하고 효율적인 방법으로 사료된다.

This study is aimed to compare the effect of visuo-perceptual biofeedback sitting balance training and conventional sitting balance training using Balance Master on stroke patients with that of program in order to analyze the effect it has on dynamic postural balance. The subjects are twenty-four stroke patients who are receiving physical therapy in Ilsan Paik Hospital and can maintain sitting posture by themselves. These patients were divided to control group and experimental group randomly. In order to compare to control and experimental group before and after the balance training, they were tested with Mann-Whitney U test and in order to compared the changes before and after the balance training, they were tested with Wilcoxon signed-ranks test. The results are as follows: we measured the ability of dynamic posture balance control with limit of stability(LOS) test and rhythmic weight shift test. There was an increasing improvement in the ability of dynamic posture balance control of the experimental group that had visuo-perceptual biofeedback sitting balance control training using the Balance Master(p<0.05, p<0.01). According to the results from above, compared to conventional sitting balance training programs, visuo-perceptual biofeedback sitting balance control training using the Balance Master is considered to be a more valuable therapy in balance control improvement and physical function improvement. It is considered that if the weak points are made up, the training with Balance Master will give help to stroke patients and to patients with balance control disabilities and will further more contribute to successful rehabilitation therapy.

Purpose : The purpose of this study is to research the effects of the differences in shoe heel height on balanced performances with a balance master. Method : 40 healthy female adults were divided into 2 groups at random. All the female participants were tested by a balance master system. Differences were analyzed according to high heel shoes and low heel shoes. The ability of static postural balance control was measured by modified CTSIB and unilateral stance test, while that of dynamic postural balance control was measured by LOS (limit of stability) and rhythmic weight shift, among the programs of a balance master. Result : 1. There is no significant correlation between the ability of static and dynamic postural balance control before main test without the shoes. 2. Movement velocity and directional control ability were significant correlation compared result of in high heel shoes and low heel shoes group. Conclusion : In conclusion, the test results of the high heeled shoe group and the low heeled shoe group through a balance master system showed that the former one is inferior to the latter one.

The present study was aimed at investigating the postural control ability of volleyball players with functional ankle instability. The subjects were 26 male volleyball players were divided into 2 groups (13 subjects with functional ankle instability and 13 subjects with ankle stability) who could evaluate Questionnaire. All the male participants were tested by a Balance Master System. This study were to measure of static balance ability, dynamic balance ability, motor function the difference between functional ankle instability group and control group. Ankle instability group and stable group in postural sway ($^{\circ}/sec$) on film surface with eye closed in modified clinical test sensory interaction on balance, and left unilateral stance with eye opened and closed were significantly different (p<.05). The ankle instability group and stable group in limit of stability were significantly different (p<.05). The ankle instability group and stable group in left/right rhythmic weight shirt were significantly different (p<.05). The ankle instability group and stable group in turn time (sec) & turn sway ($^{\circ}$) during step/quick turn and end sway ($^{\circ}/sec$) in tandem walk were significantly different (p<.05). This study showed that volleyball players with functional ankle in stability were effected postural control ability by static balance & dynamic balance ability. Further study is needed to measure various athletic with functional ankle instability for clinical application.

Objective: To evaluate the effectiveness of dynamic balance exercise after intra-articular injection of hyaluronic acid (HA) therapy in elderly patients with unilateral knee osteoarthritis. Method: 30 patients with unilateral knee osteoarthritis were enrolled in this study. The patients were randomly divided into two groups: dynamic balance exercise after HA injection group (group A) and only HA injection group (group B). Both groups administered intra-articular HA injection and group A patients continued 20-session exercises for 4 weeks. The assessments were measured before injection and 4 weeks after treatment using the visual analog scale (VAS) for pain, the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) for physical function, Berg balance scale (BBS), and computerized dynamic posturography using SMART Balance Master system for balance function. Results: In both groups, significant improvements in VAS, WOMAC and balance function were observed. Compared between groups, group A showed significant improvements compared to group B in WOMAC and balance function. Conclusion: It is suggested that dynamic balance exercise may result in improved balance function and physical function in elderly patients with unilateral knee osteoarthritis.

Hemiplegic patients usually present with difficulty maintaining balance. Balance retraining is the major component of rehabilitation program for patients with neurological impairment. The purpose of this study was to investigate the effects of prorpioceptive exercise program on the improvement of balance in the patients with chronic hemiplegia. Thirty subjects (mean age $57.0{\pm}9.8$) were recruited and the subjects were divided into a proprioceptive group and a visual group. The subjects for the proprioceptive group were participated in the proprioceptive exercise program for 4 weeks, and the visual group were treated visual feedback training using Balance Master. At 4 week follow-up test, Berg Balance Scale significantly improved 1.1 points (p<.01), Timed Up & Go test improved 4.2 second (p<.01), and weight distribution during sit to stand also improved 5.0% (p<.01). As a result of this study, the proprioceptive control approach improved dynamic balance in the patients with chronic hemiplegia. It is suggested that there was no benefit of visual feedback training like as Balance Master when administrated in combination with other physical therapy interventions, compared with physical therapy alone using proprioceptive control approach to hemiplegia.

Objectives: The purpose of this study was to examine whether Temporomandibular Joint Balance Appliance-Golf (TBA-G) can improve postural control ability of healthy adults. Methods: Twenty participants (10 male, 10 female) aged 20 to 39 years were involved. Postural control ability of all participants was assessed before and after applying TBA-G with Balance $Master^{(R)}$ system. Modified clinical test sensory interaction on balance (mCTSIB), unilateral stance, weight bearing and rhythmic weight shift were used to evaluate postural control ability. Results: After applying TBA-G, mCTSIB on a firm plate with eyes open increased from 0.2 to 0.23 (p<0.05) but directional control was improved in slow and moderate velocity of front/back rhythmic weight shift test (P<0.05). In two cases with postural imbalance, most of the postural control measures improved after applying TBA-G. Conclusions: The results suggest that TBA-G could improve balance control ability. A larger controlled trial is needed to determine more accurately the effect of TBA-G on balance control ability.
