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, 1 time a day and 30 minutes a day. 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. 목적 본 연구는 뇌졸중 환자에게 게임기반 체중지지훈련을 중재하여 균형과 다리 근활성도 및 일어서고 앉기 동작에 미치는 영향에 대해 알아보고자 하였다. 방법 연구 대상자는 뇌졸중으로 인한 반신마비 진단을 받은 1년 미만의 환자 30명을 표본 추출하여, 게임기반 체중지지 균형훈련 그룹과 기능적 체중지지훈련 그룹으로 나누었으며 대상자들은 15명씩 무작위 배치하였다. 본 연구의 각각의 훈련을 8주 동안, 주 5회, 1일 1회, 1일 30분씩 중재하였다. 3차원 동작분석기로 일어서고 앉기 동작을 측정하였고, 초시계를 이용하여 5회 일어서기 수행 시간을 측정하였다. 결과 단계별 일어서고 앉기 동작 수행 시간 분석에서는 phase Ⅰ, phase Ⅱ, phase Ⅲ, phase Ⅳ 그리고 total time에서 기능적 체중지지 훈련 그룹보다 게임기반 체중지지 균형훈련 그룹에서 유의한 감소를 보였다. 기능적 일어서기 수행력 분석에서는 5회 일어서기 검사에서 기능적 체중지지훈련 그룹보다 게임기반 체중지지훈련 그룹에서 유의한 감소를 보였다. 결론 뇌졸중 환자에게 게임기반 체중지지 균형훈련은 일어서고 앉기 능력을 증가시켜 기능적 회복에 영향을 미침을 알 수 있었다. 게임을 기반으로 한 훈련이 뇌졸중 환자의 기능향상에 효과적인 중재로 생각되며, 흥미유발과 동기부여를 이끌어 지속적이며 자발적인 참여를 유도할 수 있다고 생각된다. 향후 본 연구를 바탕으로 뇌졸중 환자들의 성별, 나이, 관심사에 맞는 다양한 게임기반 훈련들의 도입으로 중추신경계 손상 환자들의 특성에 맞는 효율적인 중재 프로그램이 필요할 것으로 생각된다.

Purpose: The purpose of this study was to investigate the kinematic characteristics and muscle activities during the following two conditions: transition from half-kneel to standing on the affected leg and non-affected leg. Methods: Twenty-one hemiplegic patients participated in the study. A motion analysis system was used to record the range of motion and angle velocity of the hip, knee and ankle from the half-kneel to the standing position. Electromyography was used to record the activity of 4 muscles. Results: The statistical analysis showed that the minimum ROM of the hip joint was less on the affected leg during transition from half-kneel to standing. However, the minimum ROM of the knee and ankle joints was less on the non-affected leg during transition from half-kneel to standing. The angle velocity of the knee and ankle joints was less during transition from half kneeling to standing on the non-affected leg. Muscle activity of the rectus femoris and tibialis anterior was less while moving from half-kneel to the standing position on the affected leg. Conclusion: These results show that greater active ROM of the knee and ankle was required on the affected leg for transition from half-kneel to the standing position than for normal gait. Muscle activity of the rectus femoris and tibialis anterior is normally required for movement from the half-kneel to the standing position during normal gait. Further studies are needed to investigate the antigravity movement in healthy subjects and hemiplegic patients in order to completely understand the normal and abnormal movement from the half-kneel to the standing position.

Methods: 30 stroke patients were selected as the subjects of study, and divided them randomly into arespiratory resistance training group combining with transcranial direct current stimulation (Experiment group)and general respiratory resistance training group (Control group). All subjects of this study were providedgeneral neurologic physical therapy for 30 minutes, and then additionally provided each respiratory resistancetraining with transcranial direct current stimulation and general respiratory resistance training according togroup, 5 times a week for 30 minutes for totally 8 weeks. Pulmonary function was analyzed before theintervention. The strength index, peak inspiratory flow and 6-minute walking test were measured in order toanalyze the breathing function. The analysis between the groups was performed by re-measuring above itemsequally after 8 weeks of intervention. Results: Respiratory resistance training group with transcranial direct current stimulation (Experiment group)has statistically meaningful difference in pulmonary function compared to the general respiratory resistancetraining group (Control group) based on the comparative analysis of strength index, peak inspiratory flow and6-minute walking test between two groups. Conclusion: As a result of above, it was found that respiratory resistance training with transcranial directcurrent stimulation was more effective for pulmonary function. This training shall be proposed as an effectiveprogram not only for the stroke patients but also for normal people or pro-athletes based on this study. Futurestudies on muscle changes related to pulmonary function are necessary in the future based on this study.

Purpose: To examine the effect of biofeedback balance training combined with taping on the lower extremitymuscle activity of badminton club members with chronic ankle instability. Methods: Thirty badminton club members were selected as the study participants and divided into abiofeedback balance training group combining taping (experimental group), and a general biofeedbackbalance training group (control group). Fifteen participants were randomly assigned. Additionally, the studyparticipants implemented biofeedback balance training combining taping and general biofeedback balancetraining for 30 min five times a week over an 8-week period, after receiving general badminton training. Lowerextremity muscle activity was analyzed before the intervention. The peroneus longus, peroneus brevis, andtibialis anterior were measured by maximum voluntary isometric contraction in the bare-handed musclestrength test to analyze the lower extremity muscle activity. The above outcomes were equally remeasured,and intergroup analysis was conducted after 8 weeks of intervention. Results: The biofeedback balance training group combining taping (experimental group) showed a significantdifference in lower extremity muscle activity compared to the general biofeedback balance training group(control group) (p<0.05). Conclusion: Biofeedback training combining taping is more effective in improving lower extremity muscleactivity. Basic data on the possibility of using taping and biofeedback in the field of sports rehabilitation ofbadminton players could be provided based on this study.
