PURPOSE: The purpose of present study was to determine effects of circuit class training (CCT) on the synthesis of central serotonin in people with post-stroke depression. METHODS: Forty patients with mild post-stroke depression were participated in current study. All subjects were assigned to two groups of CCT (circuit class training) group and SW (stretching and weight shifting) group. Both groups were performed for 80 minutes. The change of blood f-Trp, BCAAs, f-Trp/BCAAs and serotonin according to period training time were examined and the following results were obtained. RESULTS: In the CCT group, f-Trp, BCAAs, and f-Trp/BCAAs increased according to the time point. However, after 24 hour of circuit class training, all of these were significantly decreased by those before training. The change in blood levels of serotonin was the highest in immediately after the training in the CCT group while it was not changed significantly in the SW group. CONCLUSION: It can be seen that CCT can change the serotonin level and have an effect on the synthesis of central serotonin in people with post-stroke depression.

This study was performed to investigate the effects of low-power Helium Neon Infra Red(He-Ne IR)laser irradiation and exercise on the regeneration of experimentally cut sciatic nerve in rats. The thrity Sprague-Dawley adult mail rats were assigned to the 6 groups : normal group(1), injured control groups(2), experimental groups(3). There was made artificial injured in the sciatic nerve of rats the each experimental laser group and exercise group were treated from 3 days after being injured for the 5 minutes(laser group), 10 minutes(exercise group), and 15 minutes(exercise and laser group) everyday during 2 weeks. There were measured the changes of amplitude of compound muscle action potential and histological change by the light microscopy on the sciatic nerve injured rats. The results obtained as follows : 1. In the control groups, the regeneration were slowly and slightlly progressed to compared with the experimental groups. Inflammation were much more observed, and fibrous adhesion was also observed around the sutured region of the cut sciatic nerve. 2. The amplitude of compound muscle action potential in the experimental groups were significantly increased to the injured control groups at 1 week(p<.05). The compound muscle action potential of the exercise and lased group was significantly decreased to be similar to normal group at 2 weeks(p<.05). 3. In histologic finding, in the experimental groups were observed the proliferation of the schwann cells, the infiltration of inflammatory cells and the extent of destruction at adjacent tissue were remarkably decreased on the 2 weeks. From these experimental results, it may be suggested that the laser and exercise were effected the heeling process of peripheral nerve injuried rats.

본 연구는 만성기 뇌졸중 환자들을 대상으로 8주간 균형운동이 뇌졸중 후 우울증의 개선과 우울증과 관계있는 세로토닌에 긍정적인 영향을 미치는 가를 알아보기 위하여 연구의 목적에 부합되는 뇌졸중 환자 21명을 선별하여 무작위로 9명의 운동군과 12명의 대조군을 선정하여 매회 50분간, 주 3회, 8주간의 밸런스 트레이닝을 실시하였고 트레이닝 전과 후에 각 그룹의 Berk Depression Inventory(BDI)검사와, 세로토닌을 측정하여 다음과 같은 결과를 도출하였다. 8주간의 밸런스 트레이닝 후 BDI 검사의 점수는 대조군과 운동군 모두에서 낮아졌지만 운동군에서 유의하게 낮아져 밸런스 트레이닝이 뇌졸중 환자의 우울증상 개선에 효과가 있었으며 세로토닌은 대조군에서 낮아졌지만 운동군에서는 유의하게 높아져 밸런스 트레이닝이 뇌졸중 환자의 세로토닌을 증가시키는데 효과가 있었다. 이와 같은 결과는 결국 뇌졸중 후의 재활치료과정에서 물리치료와 병행하여 밸런스 트레이닝을 실시하는 것이 환자들의 우울증상 개선에 보다 효과적이라는 것을 나타낸 것이라 할 수 있다. 향후 연구에서는 우울검사 뿐만 아니라 보행과 같이 중앙 패턴 발생기를 이용한 반복적이고 지속적인 동작과 관련된 연구도 진행되어야 할 필요성을 가지고 있다. The objective of this study was to evaluate the group balance training on the depression and the changes of serum serotonin levels in people with chronic hemiparetic stoke.

Purpose:The purpose of this study was to examine the feasibility and efficiency of balance training program through an interactive video game regimen in people with chronic stroke. Methods:Thirty patients with chronic hemiparetic stroke were recruited. Participants were randomly assigned to either a control group (n=15) or an experimental group (n=15). The control group received the general physical therapy including of strengthening and balance exercise five times a week whereas the experimental group received a program of balance exercise with video game play based on virtual reality as well as the same typical physical therapy. The experimental group received 6 sessions for four weeks. Each session was given 5 minutes. An interactive computer game exercise regimen lasted 30 minutes without rest periods. Outcome measures for weight transfer to paretic side, non-paretic side and sit-squat-speed, sit-squat-length, sit-to-standspeed and sit-to-stand-area for the control group (n=15) and experimental group (n=15) before and after treatment were obtained by using the biorescure. Results:Outcomes demonstrated significant improvement in the experimental group compared with the control group in weight transfer to paretic side, non-paretic side and sit-squat-speed, sit-squat-length, sit-to-stand-speed. No significant training effect was showed in sit-to-stand-area between pretraining and post-training. Conclusion:An interactive computer game exercise based on task oriented approach for balance in chronic stroke were feasible. In other words, This regimen resulted in a greater improvement in dynamic balance for people with chronic stroke.
