Purpose： This study is to identify the effect of a thera-band exercise program on the physical function of elderly women. Methods： The subjects included 54 elderly women who participated in the program at J Senior Welfare Center in Jeollabuk-do. They were divided into two groups, 30 elderly women of control group and 24 of experimental group. A thera-band exercise program was conducted to both groups for total eight weeks―three times a week with a 50-minute period. After/before the experiment, the following seven categories were estimated for each subject: cardiopulmonary endurance, lower extremity power, upper extremity power, muscle endurance, flexibility, equilibrium, and agility. Results： There was a significant increase on the physical function of all the subjects in the experimental group and the control one after the experiment. Furthermore, the experimental group showed more meaningful improvement than the control one. Conclusion： On the basis of these findings, the thera-band exercise program contributes the enhancement of physical function of elderly women. Thus, more various physical exercise program should be developed for healthy aging.

Purpose： The purpose of this study was to analyze the effect of closed kinematic chain exercise and proprioceptive neuromuscular facilitation exercise on the static⋅dynamic balance performance of hemiplegic patients in order to suggest them therapeutic intervention methods. Methods： The subjects of this study were 18 hemiplegic patients grouped into 2 subgroups according to the exercise program. one group of closed kinematic chain exercise carried out sit to stand, Hooklying with pelvic lift(bridging) and stair-up & down by a hemiplegic leg. The other group of proprioceptive neuromuscular facilitation exercise carried out leg flexion-extension pattern in supine position, leg flexion pattern in standing and stabilizing reversal exercise in stating position. Each exercise was carried out over 3 sets of 10reps. Results： The results of this study were summarized as follows: 1. For both groups, there were statistically significant changes in the static balance (FICSIT-4) performance after exercise program (p<.05). 2. For both groups, there were statistically significant changes in the dynamic balance (FSST, TUG, FRT) performance after exercise program (p<.05). 3. In the comparison between both groups, there was no statistically significant difference in the static⋅dynamic balance performance (FICSIT-4, FSST, TUGT, ER) after exercise program. Conclusion： As the results of the study shows closed kinematic chain exercise and proprioceptive neuromuscular facilitation exercise affect the improvement of hemiplegic patients’' static⋅dynamic balance performance, it is supposed that these exercises could be therapeutic exercise program in clinical situations.

Purpose： The aim of this study was to investigate the correlations between body compositions and bone mineral density in young women and postmenopausal women with low bone mineral density. Methods： Eleven young women (age, 25.85±1.96 yrs; height, 160.28±2.16 cm; weight, 56.89±9.66 kg) and ten postmenopausal women (age, 25.85±1.96 yrs; height, 160.28±2.16 cm; weight, 56.89±9.66 kg) with low bone density on femur neck were participated in this study. All subjects performed the measure of body composition and BMD on lumbar body and femur neck. Results： The results were as follows. Percent body fat, waist-hip ratio and body mass index(BMI) were significantly increased in postmenopausal women. BMD in lumbar body and femur neck were significantly decreased in postmenopausal women. There were negative strong correlation between BMD of the femur and age in young women. There were negative strong correlation between BMD of the femur and age or the years of menopause in postmenopausal women. There were positive strong correlation between BMD of the femur and BMD of lumbar body. Conclusion： Percent body fat and BMI were more increased in young women than in postmenopausal women. And there were negative strong correlation between BMD and age or the years of menopause in postmenopausal women.

Purpose： The aims of this study was to identify changes mu rhythm according to familiarity with a stimulus in people with stroke. Methods： Seventeen right-handed participants were asked to observe 2 different stimulus; a non-familiarity stimulus condition (NFSC), and a familiarity stimulus condition (FSC). Electroencephalogram (EEG) signals from electrodes on the participant`s scalp were recorded during action observation. The activation of the mirror neuron system was compaired between FSC and NFSC by a paired t-test. An independent t-test was used to compare the difference between right and left hemispheres for the activation of the mirror neuron system during action observation of performing a task with the right hand. Results： The result of paired t-test showed no significantly difference between NFSC and FSC in the activation of the mirror neuron system. The Result of independent t-test also showed no significantly difference in the activation of mirror neuron system between the right and left hemispheres. Conclusion： The familiarity with a stimulus had no signigicant effect on the activation of the mirror neuron system according to the familiarity and in either the right or left hemispheres in people with chronic stroke.

Purpose： The purpose of this study was to assess the tibialis anterior, soleus, gluteus maximus, transverse abdominis muscle activity of tibialis anterior, soleus, gluteus maximus, transverse abdominis according to pronated foot and supinated foot. Methods： Group of pronation and supination were taped using augmented low-day method to make pronated and supinated foot the three case were assessed by agnostic radiology for investigating foot structure. Results： 1) When supinated foot & pronated foot, tibialis anterior & gluteus maximus muscle activity was augmented in one step. 2) When supinated foot & pronated foot, soleus & transverse abdominis muscle activity was decreased in one step. 3) When supinated foot & pronated foot, tibialis anterior & gluteus maximus muscle activity was augmented in squat. 4) When supinated foot & pronated foot, soleus muscle activity was decreased in squat. 5) When pronated foot, transverse abdominis muscle activity was decreased in squat. 6) When supinated foot, transverse abdominis muscle activity was augmented in squat. 7) When pronated foot, transverse abdominis & gluteus maximus & tibialis anterior muscle activity was augmented in sit to stand. 8) When supinated foot, transverse abdominis & gluteus maximus & tibialis anterior muscle activity was decreased in sit to stand. 9) When supinated foot & pronated foot, soleus muscle activity was decreased in sit to stand. Conclusion： 1) Pronated foot & supinated foot effects on soleus, gluteus maximus, transverse abdominis muscle activity in one step. 2) Pronated foot & supinated foot effects on tibialis anterior, gluteus maximus, transverse abdominis muscle activity in squat. 3) Pronated foot & supinated foot effects on soleus, transverse abdominis muscle activity in sit to stand. Therefore we suggest the deformity of the foot effects on tibialis anterior, soleus, gluteus maximus, transverse abdominis muscle activity.

Purpose： The aim of this study was to identify of bilateral trunk rotation(BTR) exercise and PNF exercise on gait in the individuals with malalignment syndrome. Methods： Subjects were 32 that were divided 2 groups in 20's generation. Interventions were trunk ratation exercise and PNF exercise. We used Medex for trunk rotation exercise. BTR group received exercise for three-sets (10min/set) along with stretching exercise ten-minutes, 3 times per week. PNF group took turns the D1 pattern in upper extremity and the D1 pattern in the opposite side of lower extremity for three-sets (10min/set). The measurement were force metatarsal 1 (FM 1), impulse metatarsal 1 (IM 1), force heel lat (FHL), impulse heel lat (IHL) by using footscan (RS scan). Statistical method was repeated measurement of ANOVA and p value was 0.05. Results： BTR and PNF group were significantly different in time(FM 1, IM 1, FHL, IHL). As different of right/left, BTR and PNF exercise were significantly different in FM 1, IM 1, FHL. Conclusion： BTR exercise was good exercise for malalignment but needs expensive equipment, for example, Medex. PNF exercise doesn't need expensive equipment but good method in malalignment syndrome person for gait ability. If PNF exercise is more experiment, PNF exercise could use variety for more patients.
