본 연구의 목적은 만성 뇌졸중 환자를 대상으로 전정자극훈련 프로그램이 정적 균형 및 동적 균형에 미치는 영향을 알아보는 것이다. 본 연구는 2014년 7월 15일부터 9월 6일까지 진행하였으며, 대상자는 뇌졸중 진단을 받은 환자 20명이 본 연구에 참여하였고, Group Ⅰ(일반운동치료, n=10)과 Group Ⅱ(전정자극훈련, n=10)로 나누었다. 두 군 모두 주 3회, 회당 40분씩 6주간 치료적 중재를 실시하였다. 균형 능력은 Good Balance System을 이용하여 정적 균형 및 동적 균형을 측정하였으며, 중재 전과 후를 비교하였다. 연구 결과, 전정자극 훈련군에서는 눈감고 선자세의 좌우 및 전후 균형, 눈뜨고 선자세의 좌우 및 전후 균형, 이동시간, 이동거리에서 통계학적으로 유의한 차이를 보였고, 일반운동 치료군에서는 눈뜨고 선자세의 좌우 균형을 제외한 모든 항목에서 통계학적으로 유의한 차이는 보이지 않았다. 결론적으로, 본 연구에서 전정자극 훈련은 만성 뇌졸중 환자의 정적 균형 능력과 동 적균형 능력 향상에 긍정적인 영향을 미쳤으며, 이러한 뇌졸중 환자의 균형 능력 향상을 위한 치료프로그램에 다양한 방법으로 활용될 수 있을 것이다. This study examined the effects of vestibular stimulation training on the static and dynamic balance of patients with chronic stroke. This study was conducted from July 15th to September 6, 2014 and 20 subjects diagnosed with stroke participated in this study. The subjects were divided randomly into Group Ⅰ(general therapeutic exercise, n=10) and Group Ⅱ(vestibular stimulation training, n=10). Both groups were trained for 40 minutes, 3 times a week, for 6weeks. The balance ability, static balance and dynamic balance, were evaluated using a Good Balance System and compared before-and-after intervention. In the vestibular training group, there were statistically significant differences in the left-right and anterior-posterior balance with the eyes closed and standing posture, in the left-right and anterior-posterior balance with the eyes open and standing posture, and moving time and distance. In the general therapeutic exercise group, there was no significant difference except in the left-right balance with the eyes open and standing posture. In conclusion, vestibular stimulation training had positive effects on the static and dynamic balance of chronic stroke patients, and this training can be effective in a treatment program to improve the balance ability of stroke patients.

Purpose: The purpose of this study was to investigate the effects of low intensity pulsed ultrasound on TGF-β1 expression and healing of rat femur penetrating fractures. Methods: Rats were anesthetized with ketamine and xylazine. Using aseptic technique, we exposed the lateral right femoral diaphysis with removal of the periosteum. We made one hole along its long axis with an electrically-driven 1.8 mm diameter drill bit. Postoperatively, rats were divided into two groups (a control group, n=15; an experimental group, n=15). The experimental group was treated with low intensity pulsed ultrasound (pulse rate: 1:4, 0.5 W/cm2, 10 minutes, 1 time per day) for 3 weeks. The control group was treated with sham ultrasound (with the US unit turned off). Results: The experimental group achieved more callus formation and TGF-β1 expression than the control group at the 7^th, 14^th and 21^st days after low intensity pulsed ultrasound treatment. Conclusion: This study suggests that low intensity pulsed ultrasound facilitates bone fracture repair, possibly via increased TGF-β1 expression.
