This study is to compare muscle strength between isotonic exercise and isotonic & isokinetic exercise. Participants are 12-man and 10-woman whom they are healthy without medical history in shoulder, elbow and lumbar joint. We performed experiment total 4-weeks that exercise 3-days a week each exercise pattern. We measured shoulder, elbow and lumbar joint torque with BIODEX and circumference of muscle in upper arms once a week. The result showed that isotonic & isokinetic exercise pattern significantly more improved joint torque in shoulder, elbow, lumbar than isotonic exercise pattern. Because that isotonic & isokinetic exercise pattern supplied muscle strengthen and caused muscle contraction. This exercise pattern can be used new exercise training method for major athlete and normal people. Also this pattern can be used rehabilitation treatment.

The purpose of this research was to investigate the effects of dried orange peel compound intaking and exercise training on the physique, body fat, and concentration bloodlipid in obese women. Ninety-seven volunteers(mean age 21.47 ${\pm}$ 1.47 yrs), all over 30% of body fat, agreed to Participate and were placed in 4 groups: dried orange peel compound intaking and exercise group(n=25), only exercise group(n=25), only dried orange peel compound intaking group(n=24), and control group(n=20). The subjects who joined this project were asked to take dried orange peel compound(2 times/day, 30 ml/time) or participate in exercise program(3 times/week, 70 min/day), depending on particular group for 12 weeks. They were tested on their height, weight, circumference of chest, abdomen, hip, and thigh, body fat%, total-cholesterol(TC), HDL-C, LDL-c, and triglyceride(TG) at the beginning and the end of the 12-weeks program. For data analysis, paired t-tests and ANCOVAs were used. The intaking of dried orange peel compound was influenced on weight, circumference of chest, abdomen, hip, and thigh, body fat%, HDL-C, LDL-C, and TG. The exercise participation had almost same effects on those dependent variables. Furthermore, the dried orange peel compound intaking along with exercise training was the most effective on those dependent variables among them. Therefore, these results indicate that dried orange peel compound intaking, like exercise, may be useful for controling weight, body fat, HDL-C, LDL-C, and TG.

Purpose: We investigate to evaluate the effects of scapular stabilization exercise on dynamic standing balance in stroke patients. Methods: Thirty hemiplegic patients participated was divided into control group and training group randomly. Control group(n=15) had only general rehabilitation training and training group (n=15) had both the general rehabilitation training and intensive scapular stabilization exercise. They were treated for 15minute/5 times/4 week. We measured PALM (palpation meter) to measure affected side's distances from spine to scapular. We measured FRT (functional reach test), FSST (four squared step test), and BPM (balance performance monitering) to evaluate dynamic standing balance. Results: Training group showed a significant difference in the distances from spine to scapular, FRT, FSST, and variables of BPM comparing control group (p<0.05). But control group was not significant difference. Conclusion: These results suggest that scapular stabilization exercises have positive effects on dynamic standing position.

This study performed in order to investigate the effect of isometric resistance exercise for vastus medialis oblique muscle with EMG(electromyography) biofeedback training which are applied to the patello-femoral joint of patients with osteoarthritis on the improve of function. The subjects had no neuromuscular disorders, and they were elder patients with osteoarthritis, 20 women. And the experiment was performed in control group, taping with EMG biofeedback training group respectively, and the measurement was carried out before and after the treatment and 4 weeks after the treatment. Motor unit action potential analysis with surface electromyography showed a significant change in RMS(root mean square) amplitude and MDF(median frequency) in vastus medialis oblique muscle(p<0.05). VMO/VL(vastus medialis oblique/vastus lateralis oblique) MDF ratio showed a significant change between groups(p<0.05). Taping with EMG biofeedback training applied to patello-femoral joint of osteoarthritis patients appeared to be effective for muscle function improvement. However, increase of muscular force in vastus medialis oblique muscle appears to have a positive effect on improve of function along with correction effect on patella malalignment. In conclusion, in case of osteoarthritis patients with loss of patello-femoral joint function, it appears to be effective to practice isometric resistance exercise of vastus medialis oblique muscle selective with taping.

Background: The purpose of this study was to investigate effects of six-week biofeedback training for prevention of falling in elderly persons. Biofeedback training for using the TETRAX system. Methods: Thirty healthy elderly persons(men=17, women=13) who were 79 years of mean age participated in sensory regulation training. They were trained for thirty minutes a day, three times per week. We measured subjects sensory regulated function by TETRAX system, and analyzed mean difference of observed variables by paired t-test between the pre and post test. Results: The first experimental group were significantly difference between pre and post test. The second control group were not significantly between the pre and post test. The third there are significant between group. Conclusion: The results of this study reveal that biofeedback training exercise will improve sensory balance function, and further studies needs to identify which specific factors are related to fall in the elderly population, and it is expected this study may contribute in reducing fall and therapeutic exercise in falling.

Cerebral palsy children represent abnormal vocalization pattern caused by respiration problem and paralyzed oral motor muscle that are the basics of speech production. Thus, this study examined the effect of respiration and articulator training programs on the basic ability of speech production in CP children. The subjects of this study were 4 children with 3 of spastic CP and 1 of ataxia CP. The respiration and articulator program was conducted in 30 sessions for 30 minutes each. Pre-test was administered twice before the program, ongoing test was administered every 5 session during the period of experiment, and post-test was administered twice. The program included speech production such as respiration training, lips, jaw, cheek, and tongue exercise, and velopharyngeal training, and related articulator training. The following results were obtained. First, all subject children were less than 5 seconds in maximum phonation time before the experiment and 2 were improved by more than 4$\sim$5 seconds during the experiment, but 2 had relatively low rising width. Second, while children with less than 30dB before the experiment became bigger in strength during the experiment, children with more than 35dB before the experiment showed a minor change. Subject child 4 had lower vocal strength in the post-test period. Finally, although each subject had individual difference in syllable diadochokinetic ability, the function was improved and the number of repetition in one respiration was also increased.

Purpose: This study was conducted in order to investigate the effectiveness of an 8-week virtual reality exercise program designed around the Nintendo Wii (Wii), in improving balance among patients with Multiple Sclerosis (MS). Methods: The study included 16 patients with MS (10 female, 6 male) who were assigned randomly to experimental (n=8) or control group (n=8). Experimental group performed three 40-minute Wii balance-training sessions per week, for 8 weeks. The control group did not perform any of the training programs. A computerized dynamic posturography (Sensory Organizing Test, SOT) was used to evaluate all patients at baseline and at the end of the treatment protocol. Statistical significance was tested in between the patients before and after treatment by t-test. Results: After 24 training sessions, SOT showed significant difference on condition 5, 6, and vestibular ratios within the experimental group from baseline to post-intervention. By contrast, no significant difference was observed within the control groups. Conclusion: These findings demonstrated that the virtual reality training program could improve the outcomes in terms of balance in the MS population. Long term follow ups and the development of more efficient virtual reality training programs are needed.

Purpose: The purpose of this study was to determine whether a balance training program could improve the balancing ability of elderly patients with type II diabetes mellitus. If yes, the results could lead to development of a method to prevent falls in elderly patients with type II diabetes mellitus (DM). Methods: Subjects were 28 elderly patients with type II DM. Subjects were divided into a control and an experimental group with 14 patients in each group. The experimental group had a balance training program consisting of balance training and lower extremity muscle strengthening exercises. The exercise group met twice a week for 8 weeks. All subjects were evaluated using a force plate for the amount of postural sway. To determine the degree of diabetes, we measured Hemoglobin A1c. Results: Balance in the experimental group (p<0.05) increased significantly compared to the control group. Conclusion: The results suggest that a balance training program should be recommended for improving balance and preventing falls in elderly type II DM patients.

Purpose: We investigated a better method to enhance the vestibular system including balancing by comparing the vestibular stimulation exercise (VSE) and galvanic vestibular stimulation (GVS). Methods: The study was performed with 40 subjects randomized into four groups, including a control group, a VSE group, a GVS group, and a VSE with GVS group. The subjects of VSE performed a forward and backward roll, a right side and left side roll, and an equilibrium board in vestibular stimulation training. GVS was applied for 10 minutes and the cathode and anode side were then changed and GVS was then applied for the remaining 10 minutes. GVS was applied for 20 minutes to the subjects of this group after completion of the VSE program. Results: In the control group, all conditions were significantly decreased (p<0.05) compared to the VSE with GVS group. Also, the center of pressure (CoP) surface was more significantly decreased (p<0.01) and the CoP speed was significantly decreased in the one legged stance (p<0.05) in the control group compared to the GVS group. Conclusion: These findings suggested that GVS training increases balance ability in a narrow width. VSE with GVS training is therefore recommend as the superior method. Using GVS or VSE with GVS training is considered to clinically improve balance ability by stimulating the vestibular system.
