The purposes of this study were to compare the electromyographic activities and recruitment time from the rectus femoris, vastus medialis oblique and vastus lateralis during maximal isometric exercise with and without patellofemoral pain syndrome patients. 24 people (12 healthy people and 12 PFPS patients) participated in the study. All participants performed isometric exercises while electromyographic activity was recorded from surface EMG. The results as followed, healthy people revealed similar shame remaining muscles excepts the rectus femoris. Vastus lateralis of PFPS patients revealed remarkable higher than other muscles. Also Vastus lateralis recruitment time of PFPS patients was recruited earlier than healthy people. Following researchs for the muscular power reinforcement of the vastus medialis oblique must be studied for treatment of the PFPS patients.

Purpose : The purpose of this study was to evaluate the effects of the height increase elevator shoes insole on the gait parameters and dynamic balance, static balance, predictive balance in adult male. Methods : The subjects were recruited 50 male without orthopedic disabilities, vestibular damage or visual impairment. The test of gait and balance performed on Treadmill Gait Analysis(TGA)-Functional Training System(FTS), Balance Biodex System(BBS), Functional Reach Test(FRT) test according to 0㎝, 5㎝, 7㎝ of the height insole. The order of height of insole was randomly selected. The data was conducted by one-way repeated measures ANOVA. Results : The step length(left), walking time(right), the number of steps on gait parameters were a statistically significant difference according to increased height of insole(p<.05). The dynamic and static balance were significant differences at 7㎝ height of insole(p<.05). Predictive balance was a statistically significantly difference according to increased height of insole(p<.05). The results of this study implicated to be reduced the ability of balance and changed gait parameters according to increased height of insole.

Purpose: The purpose of this study was to investigate the effects of three exercise programs on forward head posture. Methods: Ninety-five individuals were recruited to assess the of the pectoralis minor muscle. Of these, 36 individuals with pectoralis minor muscles were selected and randomly divided into three groups: a functional massage group, a stretching group, and a stretching and muscle strengthening group. The exercise program consisted of sessions four times per week for two weeks. The length of pectoralis minor and the activity of the trapezius muscles were measured using electromyography. Forward head posture was assessed using the craniovertebral angle (CVA) and the cranial rotation angle (CRA) pre-, during and post-treatment. Result: Significant improvements were observed in pectoralis minor length, CRA, and CVA post-treatment in all groups (p<0.05, p<0.01, p<0.001). However, only the activity of the lower trapezius demonstrated a statistically significant difference post-treatment. There were no significant differences between the groups. Conclusion: The findings of this study suggest that all three exercise programs were effective in improving forward head posture and the length of pectoralis minor post-treatment.

The purpose of this study was to determine the effects of FES on the clinical test patients who had disturbance gait due to cereberal vascular accident. The subjects for study were 16 hemiplegic patients (9 Male and 7 Female) who can gait with or without device. Their average age was 55 and they received average of 20.19 month of treatment collected data analysis was completed by using one-way analysis variable(ANOVA), Pearson ($-1{\leq}r{\geq}1$). The results were as follows : 1) There was difference in four variable (stride length,gait speed,gait cadence) between at the biginning and at the end of the treatment of FES (p<0.01). 2) There was relationship in capacity of activity between MAS and stride length (r = 0.751), gait speed (r = 0.689) but no relationship gait cadence (r = 0.236). 3) Age revealed relationship of stride length (r = -0.727), gait speed (r = -0.725), gait cadenc (r = -0.362). 4) There was no relationship in months post-CVA with MAS (r = 0.171), stride length (r = -0.110), gait speed (r = -0.096), gait cacedce (r = -0.154).

Purpose : The purpose of this study was to compare the effects of Tabata exercise and Kettle bell exercise on vital capacity, skeletal muscle mass, and endurance in women. Methods : Twenty subjects participated in this study. They were divided into two group: a Tabata exercise group (n=10) and a kettle bell exercise group (n=10). Both groups performed their assigned exercise 3 times a weeks for 6 weeks. Result : There were statistically significant differences in FVC, FEV1, FEV1/FVC, PEF, and VC (p<.05) between the Tabata exercise group and the kettle bell exercise group. There were also statistically significant differences in skeletal muscle mass and endurance function (p<.05) between the two groups. The Tabata exercise group demonstrated greater improvements in fitness parameters compared to those demonstrated by the kettle bell exercise group. Conclusion : The Tabata exercise group was more effective at increasing vital capacity, skeletal muscle mass, and endurance compared to the kettle bell exercise group.

This study was conducted to identify Dynamic Surface EMG activities of back muscle, gluteus maximus, hamstring muscles in 20 adult men and women who simulated leg length difference. Subjects were healthy 20 adults who have no back pain and orthopaedic problems. The measurement tools used Myotronics-Noromed MES 9000 EMG and thickness used each 2, 3, 4cm scaffold, protractor, micro- chronometer etc. Surface EMG activities were recorded during active trunk flexion(0˚, 45˚, 90˚) in stand position. Next, Surface EMG activities were recorded during active trunk flexion according to scaffold height on left leg(each 2, 3, 4cm). Analysis method enforced Two-way repeated ANOVA. The results were as follows. 1) According to increase height of left leg, Surface EMG activities of left back muscle and right gluteus maximus were increased, Surface EMG activities of right back muscle and left gluteus maximus were looked inclination that decrease generally but it was no statistical significance(p > 0.05). 2) During the trunk 45˚, 90˚ flexion, Surface EMG activities of almost all muscle were increased. Specially, Surface EMG activities of back muscles was the highest during the trunk 45˚ flexion. However, Surface EMG activities of back muscle of the trunk 90˚ flexion were lower than that trunk 45" flexion. And, Surface EMG activities of gluteus maximus were the lowest to increased leg length.

Purpose : The most effective intervention for flat foot is strengthening exercises for the intrinsic and extrinsic of the foot. Additionally, visual feedback is necessary for movement accuracy. However, the effectiveness of the intervention when combined with visual feedback was not revealed. To confirm this, the research was to investigate the effect of visual feedback and a complex exercise program on navicular bone height, plantar pressure, and lower extremity alignment. Methods : The twenty eight adult men and women with flat foot were randomly assigned to group 1 (n=14) and group2 (n=14), group1 performed complex exercises with visual feedback, and group 2 performed only complex exercises. Both groups performed a 40 minute compound exercise program three times a week. Navicular drop test, plantar pressure test, and lower extremity alignment test were performed equally in both group. Results : As a result of comparing the change in navicular height within the group according to the intervention, both groups showed a significant difference before and after the exercise (p>.05). There was not significant difference comparing the difference between the groups in the navicular height (p>.05). Comparing the change in plantar pressure within groups, there was not significant difference in the change in plantar pressure in both groups (p>.05). Coparing the difference before and after exercise between groups, there was not significant plantar pressure (p>.05). Comparing the change in leg alignment within the group, there was a significant difference in the change in ankle before and after exercise in group 1 (p<.05), but there was not significant difference in group 2. There was not significant difference in pelvic tilt and knee tilt before and after exercise in both groups (p>.05). Comparing the before and after exercise difference between groups, there were not significant in all variables of leg alignment (p>.05). Conclusion : The results of this study showed that complex exercise applied to patients with flat foot were effective in increasing the height of the navicular bone and ankle angle, but there was no effect due to visual feedback.
