Purpose : The purpose of this study was to study the effect of rectus abdominal muscle contraction by proprioceptive neuromuscular facilitation trunk stabilization training using extremity simultaneous pattern (PNF trunk stabilization training) and traditional trunk stabilization training methods. Methods : A group of 24 adults male and female, healthy, with no previous medical history nor disability in neuromuscular system and musculoskeletal system was chosen as subjects, and was divided into a control group, a PNF trunk stabilization training group and a traditional trunk stabilization training group. Experiments were performed on the last two groups, 3 times a week for 6 weeks, totaling 18 times. Using a dynamometer, muscle strength and endurance time on trunk flexion were measured before and after each experiment, and surface electromyography in left and right rectus abdominis were measured. Results : following results were obtained; 1. As for the change in the maximal voluntary isometric contraction (MVIC), all subjects in the trunk stabilization training group showed significant difference from those in the control group. 2. As for surface electromyography measurement and the changes in root mean square at the time of trunk flexion, in the left rectus abdominis, PNF trunk stabilization training group showed significant difference from the control group, while in the right rectus abdominis, traditional trunk stabilization training group showed significant difference. Conclusion : To sum up the results, both trunk stabilization training groups showed improvement in the MVIC of abdominal muscle, motor unit action potential activity, but the difference between two trunk stabilization training groups was not significant. Therefore, while trunk stabilization training significantly improved abdominal muscle contraction, but the difference attributable to training methods was found to be insignificant.

In this paper, the effects of the external-rotation exercise on the gait of hemiplegia was investigated. 26 patients with hemiplegia due to cerebrovascular accident participated in this study. Subjects were randomly assigned to experimental group(n=12) and control one(n=14). 12 subjects of the experimental group were received the external rotation reducing exercise on the mat with seating and supine posture after the general therapeutic exercise for hemiplegia. 14 subjects of the control group were received only general therapeutic exercise. The effects of external rotation reducing exercise were evaluated by measurements of gait velocity, cadence, stride length, step length and foot angle using ink-foot prints. The collected data were analyzed statistically based on Wilcoxon, Mann-Whitney and correlation analysis. After treatment of three weeks, it turned out that external rotation reducing exercise has the significant effect on foot angle(p<0.01). However the exercise has no statistically significant direct effect on the gait velocity, cadence, stride length and step length.

Purpose : This study examines the effects of pre-eccentric exercise and stretch ing to bicepsbrachii to prevent delayed onset muscle soreness and recovery of muscular function depending on the training intensity with 28 normal adults in their twenties. Methods : The subjects were divided into a control group, a group without any previous eccentric exercise, and a stretching group. Pre-eccentric exercise group conducted exercise with the intensity of 25% of maximal voluntary contraction. Pre-eccentric exercise and stretching was applied before to induce delayed onset muscle soreness and after, 24 hour post, 48 hour post, and 72 hour post. Measurements were conducted to examine pain and muscular function changes before, immediately after, and after inducing delayed onset muscle soreness. After inducing delayed onset muscle soreness, measurements were taken at the 24th hour, 48th hour, and 72nd hour. Results : The pre-eccentric exercise group and stretching group showed a significant difference from the control group by isometric contract ion power and mechanical pain threshold as a result of measuring delayed onset muscle soreness. Conclusion : From these results, electrical stimulation using presynaptic inhibition mechanism of transcutaneous electrical stimulation (TES) had positive effects for walking ability on inhibition of muscle tone in lower extremity. The motor level stimulation group experienced a more significant effect than the sensory level stimulation group. Therefore, the transcutaneous electrical stimulation (TES) is considered to be effective on walking ability increasing through inhibition of muscle tone in lower extremity for rehabilitation of post stroke hemiplegic patients.

Purpose : The purpose of this study was to determine the effects of hip adduction using a ball on the activation of the vastus medialis oblique (VMO) and the vastus lateralis (VL) during dynamic semisquat exercises. Methods : Twenty seven participants performed three repetitions of a double-leg semisquat and squeeze semisquat (semisquat with hip adduction using a ball) at $60^{\circ}$ knee flexion. The activation of the VMO and the VL was recorded at dominant leg during both semisquat exercises using surface electromyography (MP 100). EMG data were normalized to the maximal voluntary isometric contraction (MVIC) of the quadriceps produced during seated, isometric knee extension. Results : Results of paired t-test analyses revealed that there were no differences between activity of the VMO and the VL in both double-leg semisquat and squeeze semisquat. The activity of the VMO was significantly increased in squeeze semisquat whereas there was no difference in activity of the VL between double-leg semisquat and squeeze semisquat. Conclusion : Combining hip adduction using a ball with semisquat at $60^{\circ}$ knee flexion preferentially increases the activity of the VMO. We can conclude that semisquat at $60^{\circ}$ knee flexion with hip adduction using a ball selectively recruits the VMO. Rehabilitation for quadricep imbalance should consider these findings when selecting exercises which could preferentially activate the VMO.

Purpose : The purpose of this research was to develop a proposal by investigating the work habits associated with exercise programs for the prevention of chronic back pain. Methods : The symptoms, areas and causes of musculoskeletal patients were analyzed during a three-month period in order to develop and apply prevention programs that stimulate lumbar deep layer muscle movement. Results : The results of this study show that the lumbar and shoulders are primary areas of pain. According to the literature, lumbar and shoulder pain is caused due to long periods in the standing position and unhealthy posture during work. A preliminary program was conducted for one month to study lower back pain prevention. Preliminary results of the program showed a lumbar stabilizing effect caused by the strengthening of abdominal muscles. In addition, the alignment of the spine often leads to effective action. Therefore, action-oriented programs should be implemented in order to induce contractions of the transverse abdominis muscle. Conclusion : The completed program should consider habit and practices of workers within their working environment. The promotion of health through exercise for both employers and workers is expected to bring physical and psychological benefits that will positively affect economic results.

이 연구는 비처치군, 대조군, 처치군 간의 Visual Analog Scale (VAS)와 Disability Index (Disa)의 변화를 비교하여 요통(LBP) 완화를 위한 테이핑 방법의 효과를 평가하였다. 결과는 대조군과 처치군 모두에서 테이핑의 효과를 확인했다. VAS의 ANOVA 분석에서는 그룹 간 유의미한 차이가 나타났으며, 사후 검정에서는 비처치군과 대조군, 비처치군과 처치군 간에 유의미한 차이가 나타났으나, 대조군과 처치군 간에는 유의미한 차이가 없었다. 이는 두 테이핑 방법이 요통 완화에 유사한 효과를 나타낸다는 것을 의미한다. Disa의 경우, ANOVA에서는 유의미한 차이가 나타났지만, 사후 검정에서는 이러한 차이를 확인하지 못했다. 그룹 내 t-검정에서는 대조군과 처치군에서 VAS와 Disa의 처치 전후 차이가 유의미하게 나타났지만, 비처치군에서는 유의미하지 않았다. 이 연구는 요통 완화를 위한 테이핑의 효과를 강조하며, 두 방법이 임상에서 활용될 수 있음을 시사한다. 향후 연구에서는 더 큰 샘플과 다양한 조건을 사용하여 이러한 결과를 검증해야 한다.
