Purpose: The purpose of this study was to identify the effect of anterolateral (45$^{\circ}$) and lateral (90$^{\circ}$) direction resistance, with using an elastic band, on the electromyographic(EMG) activity ratio of the vastus medialis oblique (VMO) and the vastus lateralis (VL) during squat exercise. Methods: The study subjects were 19 active people with no history of patellofemoral pain, limitation of range of motion or pain when performing squat exercise. A 'repeated measures within subjects' design was used. The subjects were asked to perform three repetitions of a 90$^{\circ}$ knee flexion squat exercise with anterolateral (45$^{\circ}$) and lateral (90$^{\circ}$) resistance and without resistance, respectively. The EMG activity of the VMO and VL were recorded by surface EMG electrodes and the results were normalized by the % MVIC value. Results: Repeated measures ANOVA's revealed that squat exercise with anterolateral (45$^{\circ}$) resistance produced significantly greater VMO/VL EMG activity ratio than that with lateral (90$^{\circ}$) resistance and without resistance (p=.013). Yet the result of contrast testing revealed that squat exercise with lateral (90$^{\circ}$) resistance showed no significant difference of the VMO/VL EMG activity ratio, as compared with squat exercise without resistance (p>0.05). Conclusion: The findings of this study suggest that squat exercise combining anterolateral (45$^{\circ}$) resistance can contribute positively to the patients with patellofemoral pain as they increase the VMO/VL EMG activity ratio.

Purpose: This study examined the effects of an elastic band resistance exercise program on the body functions and Glycosylated hemoglobin (HbA1c) of elderly people with type 2 diabetes. Methods: Twenty-seven elderly patients with type 2 diabetes were enrolled in this study (exercise group 14, control group 13). The subjects in the exercise group participated in the program for 60 minutes a day, three times a week, for 12 weeks. All the subject's body functions, HbA1c were measured to compare the following: before the intervention, at the completion of the 12 weeks intervention, and eight weeks after the intervention. Results: Compared to the control group, the exercise group showed significant improvements in the 12 week and follow-up measurement after the intervention in body function, such as the strength of the upper and lower limbs, agility and limit of stability. The body functions of the exercise group improved as the period of intervention progressed. On the other hand, the HbA1c level at each follow-up measurement was similar in the two groups. Conclusion: The 12 week elastic band exercise program is recommended as an effective intervention for improving the body functions of elderly people with type 2 diabetes. Nevertheless, a combined intervention of steady exercise, diet therapy and drug therapy will be needed for further active prevention and management of type 2 diabetes.

PURPOSE: The purpose of this study was to compare the trunk muscle activity according to the direction of upper extremity lifting using elastic band. METHODS: Thirty three healthy individuals participated in this study. Each subject performed upper extremity lifting using elastic band on two different directions (straight and diagonal). And then we compared the muscle activity of respective trunk muscles of both directions. In order to examine the muscle activity of trunk muscle, we used the electromyogram to measure peak and mean torque in shoulder 90 degree flexion with sitting position. Electromyographic activities were recorded from the external oblique, internal oblique, rectus abdominis, and erector spine muscles during upper extremity lifting. RESULTS: As a result, first, there was significant difference between two directions. The muscle activity of ipsilateral external oblique and contralateral internal oblique is significantly increased in both straight and diagonal directions (p<0.05). Second, the muscle activities of external oblique and internal oblique of both side showed significant difference in diagonal direction (p<0.05). Third, the muscle activity of erector spine of both side showed significant difference in straight direction (p<0.05). CONCLUSION: Through this study, it is important that implement diagonal direction exercise at sitting positions to help increasing muscle activity of ipsilateral external oblique and contralateral internal oblique on patients when activating the trunk muscle or stabilizing the trunk.

Purpose : This study aimed to investigate the effect of trunk postural stability maintained wearing a spiral elastic band on the upper extremity function of patients with stroke who undertook a functional activity program and to provide fundamental data useful for the application of therapeutic interventions in the clinical environment of occupational therapy. Methods : The research subjects included 16 patients with stroke who were evenly divided into an experimental group and a control group. The eight-week intervention consisted of a functional activity program aimed at improving the function of the affected-side upper extremity. The experimental group performed the functional activity program while maintaining a stable trunk posture by wearing a spiral elastic band. The control group followed the program without wearing the band. Upper extremity function was assessed before and after the intervention using a manual function test (MFT) and a motor activity log (MAL), and the effectiveness on the upper extremity function of the affected side was confirmed. Results : First, in the within-group comparison of the upper extremity function scores before and after the intervention, the experimental group showed a statistically significant difference in the MFT and MAL assessment(p<.05). The control group showed a statistically significant difference in the MAL assessment(p<.05). Second, in the between-group comparison of the change in scores after the intervention, a statistically significant difference was observed between the two groups in all assessments(p<.05). Conclusion : This study confirmed the positive effect on upper extremity function of trunk stabilization posture using a spiral elastic band. The results could be useful when implementing a task-oriented training program in the clinical environment of occupational therapy in the future, as application of the training while maintaining trunk postural stability by wearing a spiral elastic band could be more effective for improving the upper extremity function of patients with stroke.
