Purpose: This study aims to examine the effect on the lower extremity muscle activity of soccer player having chronic ankle instability by mediating neuromuscular training combining transcranial direct current stimulation. Method: Thirty college soccer players were selected as the participants of study, and divided into a neuromuscular training group combining transcranial direct current stimulation (Experimental group) and a general neuromuscular training group (Control group), and 15 participants randomly assigned. The participants of this study additionally intervented neuromuscular training combining transcranial direct current stimulation and general neuromuscular training to each group for 30 minutes five times a week for eight weeks after receiving general soccer training. The attached to active C3, C4, CZ. Lower extremity muscle activity was analyzed before the intervention. Tibialis anterior, gastrocnemius and soleus were measured by maximum voluntary isometric contraction in the in the bare-handed muscle strength test posture in order to analyze the lower extremity muscle activity. Above outcomes were equally remeasured and in intergroup analysis was conducted after eight weeks of intervention. Result: The neuromuscular training group combining transcranial direct current stimulation (Experimental group) showed a statistically significant difference in lower extremity muscle activity compared to the general neuromuscular training group (Control group) as a result of comparing and analyzing the lower extremity muscle activity between two groups(p<.05). Conclusion: It was found that the neuromuscular training combining transcranial direct current stimulation is more effective in improving lower extremity muscle activity as a result of above. The basic data on the possibility of using tDCS in the filed of soccer player sports rehabilitation could be provided based on this study.

Purpose: The study attempts to understand the effect of lumbar stability exercise of transcranial direct current stimulation on muscle activity and jump performance in soccer player. Methods: Transcranial direct current stimulation combined lumbar stability exercise have been implemented on 15 trainees and general lumbar stability exercise have been implemented on another 15 trainees for 30 minutes at 5 times per week during 8 weeks, and elector spinae, rectus abdominis, external abdominal obilique have been measured using to evaluate the muscle activity of the trunk. The counter movement jump, counter movement jump with arm swing have been measured using g-jump to measure the jump performance. Results: There was statistically meaningful difference on the elector spinae, rectus abdominis, external abdominal obilique in the muscle activity of the trunk and there was statistically meaningful difference on counter movement jump, counter movement jump with arm swing in the jump performance(p<.05). Conclusion: Based on above, it is realized that the transcranial direct current stimulation combined lumbar stability exercise is more effective than the general lumbar stability exercise on the improvement of the muscle activity of the trunk and the jump performance.

Purpose : This research intends to identify the effects of game-based weight bearing exercises on balance, muscular activation, sit to stand to sit motions of stroke patients. Method : 30 patients who were diagnosed as hemiplegia by stroke less in than a year were sampled and they were classified into two group, one of which was game-based weight bearing balance exercise group, and the other was functional weight bearing exercise group. 15 people were randomly selected for each group. Each exercise was coordinated by this research for 8 weeks, 5 days a week. 3D motion analyzer was used to measure the sit to stand to sit motions and a stopwatch was used to measure the time for stand-up motions for 5 times. Result : In terms of analyzing sit to stand to sit motions by phases, game-based weight bearing balance exercise group showed significant reduction compared to functional weight-bearing exercise group in phase Ⅰ, Ⅱ, Ⅲ, Ⅳ and total time. In terms of functional stand-up performance analysis, game-based weight bearing balance exercise group showed significant reduction compared to functional weight-bearing exercise group in 5 times stand-up examination. Conclusion : It was verified that game-based weight bearing balance exercise had positive impact on function recovery of stroke patients by enhancing sit to stand to sit capabilities. It is considered that game-based exercise was an effective intermediary for functional improvement of stroke patients, while also inducing consistent and voluntary participation by causing interest and motivation.

Purpose : The purpose of this study is to examine the effect of the segmental mobilization technique of the lower back on the characteristics of the muscles and limited of stability of chronic backache patients. Methods : The subjects of the study were 30 chronic back pain patients who were divided into groups of 15, a manual therapy group (Group I) and a spinal decompression therapy group (Group II), via random assignation. The subjects had 15 minutes of superficial heat therapy, 15 minutes of interference wave therapy, and 5 minutes of ultrasound therapy for conservative physical therapy. Additionally, manual therapy and spinal decompression therapy were administered to each group for 30 minutes, 5 times a week for 8 weeks. Before intervention, the characteristics of the muscles and limited of stability of the muscles were analyzed. After 8 weeks of intervention, the above items were re-measured in the same manner and analyzed between groups. Results : The results of comparative analysis of the characteristics of the muscles and limited of stability between groups showed that there were statistically significant differences. The manual therapy group (Group I) showed significant differences in characteristics of the muscles compared to the spinal decompression therapy group (Group II). The manual therapy group (Group I) showed significant differences in limited of stability compared to the spinal decompression therapy group (Group II). Conclusion : The result confirmed that manual therapy was more effective in the characteristics of the muscles and limited of stability. Based on this study, additional studies are necessary on the effect of various techniques of manual therapy on muscle activity and muscle thickness in chronic back pain patients. In order to develop an effective manual therapy program, studies using a variety of evaluations are needed.
