Purpose: This study examined the effects of action-observation training using the Y-Balance on the balance ability of young adults. Methods: Thirty-four healthy adults were randomized into an action-observation group (n=17) or a control group (n=17). All subjects performed the Y-Balance test before and after watching the video. The action observation group watched a video of someone performing a Y-Balance test, and the control group watched a video of scenery unrelated to the training. The subjects were measured through a Y-Balance test for both the length of the legs extended in three directions and the Y-balance composite score. Results: A significant difference in the Y-balance composite score was observed between the two groups. A part of the direction of the extended leg in the action observation group was increased significantly (posteromedial direction of the right leg, posterolateral direction of the right leg, posteromedial direction of left leg) compared to the control group. Conclusion: These results suggest that action observation training only could help improve balance.

The purpose of this study was to investigate the effect of balance training with upper extremity exercise on the improvement of balance performance in people who have had a stroke. Eighteen candidates who have all experienced a stroke, were living in Dong-Gu, Ulsan and were participating in a community based rehabilitation program, have been included in this study. The program was conducted three times weekly, 1 hour per session, for 7 consecutive weeks. Subjects were tested with 7 m and 100 m Timed Gait Test (sec), Timed Get Up and Go Test (sec), Functional Reach Test (cm) and 5 items of Berg's Balance Test at pre-training and post-training. Total balance index and balance ratios were measured by K.A.T. 3000. The balance training program performed by sitting on a chair and gymnastic ball and standing on stable and unstable surfaces during upper extremity exercises such as Proprioceptive Neuromuscular Facilitation (PNF) upper extremity pattern, picking a ball up from floor, throwing and catching it. After seven weekends of balance training, subjects showed a significant difference in balance test results. The exceptions were three items of Berg's Balance Test (p<.05). Balance index score and affected and unaffected side balance ratio had a larger improvement than pre-training (p<.05). The result of this study showed that intervention of this balance training program could improve the balance performance in people who have had a stroke.

Normal balance is defined as state in which the body is equlilibrium. It is complex motor control task, requring integration of sensory information, neural processing, and biomechanical factors. There are major two factors contribute to balance control, the neurological and the musculoskeletal. The neurological factor provides the sensory processing and motor output mechanisms that are the neurophysiological basis for response. The musculoskeletal factor provides the mechanical structure for response. When all components of two factors are operating effectively, the postural response should be appropriate and effective for good balance control. Therfore, balance can be influenced by above all factors. In addition, balance can be also influenced by muscle tone, hearing, physiological factors, and environmental factors. Physical therapists must understand factors of balance control so that we can accurately assess balance. Therefore, physical therapists have to develop useful balance measurement tools to evaluate balance.

본 연구는 아급성 뇌졸중 환자를 대상으로 컴퓨터화된 시각적 되먹임 균형 훈련 및 평가 장비인 space balance 3D와 기능적 검사인 tinetti mobility test (TMT)의 신뢰도 및 버그균형척도와의 동시타당도를 분석하기 위해 실시하였다. 아급성 뇌졸중 환자 총 23명을 대상으로 하였고 대상자에게 space balance 3D, TMT, 버그균형척도를 이용해 균형 능력 평가를 실시하였다. 검사-재검사간 신뢰도에서 space balance 3D의 정적균형과 동적균형은 중등도의 신뢰도를 보인반면, TMT의 세가지 점수와 버그균형척도는 높은 신뢰도를 보였다. 동시타당도에서 TMT의 세가지 점수, 버그균형척도, space balance 3D의 정적균형간에 각각 중등도의 유의한 (p<.01) 양의 상관관계를 보였다. TMT의 세가지 점수와 버그균형척도는 space balance 3D의 동적균형의 후좌측, 전좌측 방향과는 각각 유의한 (p<.05) 낮은 양의 상관관계를 보였지만 나머지 방향과는 유의한 상관관계를 보이지 않았다. 따라서 space balance 3D와 TMT의 균형 능력 평가는 아급성 뇌졸중 환자의 균형 능력을 평가하는데 유용하게 쓰일 수 있을 것으로 보이나 space balance 3D의 동적균형 평가는 한계점이 있었다.

The purpose of this study was to investigate the complex ankle exercises on balance. 22 participants (male: 14, female: 8) with functional ankle instability were participated. Functional ankle instability was selected to be less than 24 points using the Cumberland ankle instability tool (CAIT) with people who had severe ankle sprain and then experiencing ankle giving way. A total of 20 minutes performed three times a week for four weeks with muscle strength and balance exercises. Muscle strengthening exercise was performed with Theraband, and balance exercise was performed with unstable support plates. Biodex balance system(R) was used to measure static and dynamic balance. The dynamic balance was selected in grade 2, 4, and 8. The static and dynamic balance (grade: 2, 4,and 8) balance was significantly decreased in anterior-posterior, and medial-lateral directions (p<.05). The instability was significantly increased after exercise (p<.05). These results suggest that complex exercises are beneficial to decreasing the functional ankle instability.

Purpose : The purpose of this study is to apply kinesiology taping and dynamic taping to subjects with ankle instability and to find out the change of static balance and dynamic balance ability and to use it more usefully in daily life. Methods : The subjects were based on 30 Cumberland Ankle Instability Tool questionnaire scores of 24 or less, and were randomly assigned to the kinesiology taping group (n=15) and the dynamic taping group (n=15) to change the static balance and dynamic balance before and after taping Measured. The eyes were closed for 30 seconds and the average balance was measured three times through the Wii balance board in static balance, and the balance ability was evaluated by measuring functional reach test and star excursion balance test in dynamic balance. Results : As a result, the static balance showed significant results in the dynamic speed and the moving distance in the dynamic taping group (p<.05). However, there was no significant difference in the shaking area and the difference in the kinesiology taping group (p<.05) However, both groups showed significant differences in dynamic balance (p<.05). Conclusion : It was confirmed that the application of taping was effective for static and dynamic balance in subjects with ankle instability, and the application of dynamic taping was more effective than kinesiology taping.
