Many studies have emphasized the importance of resistive exercise to maintain a healthy human body, particular in prevention of weakening of physical strength. Recently, some studies advocated that an application of vibration as a supplementary means in a regular training was effective in encouraging physical strength. Aim of the current study was, therefore, to identify if an application of vibration in a resistive exercise was effective in encouraging physical strength as that in a regular training. A 3-dimensional virtual lower extremity model for a healthy male and virtual leg-press model were generated and synchronized. Dynamic leg-press exercises on a slide machine with/without extra load and on a footboard with vibration as well as on a slide machine with extra load were analyzed. The results of the current indicated that the application of the vibration on the dynamic leg-press exercise might be not greatly effective in encouraging physical strength, compared with the dynamic leg press exercise with extra load. It was, however, thought that the application of the vibration might be helpful to elderly individuals because the reduced maximum muscle strength appeared by the effect of the vibration may avoid a muscular spasm, which can be driven from a high muscle strength sometimes produced during the leg-press exercise with extra load.

This study was to investigate the positive effects of specially designed trunk-stabilization exercise program on lower extremity balance of elderly with history of leprosy. In this participants, lower extremity functions has been undermined by the development of damage in peripheral nerves. A total of 40 elderly with history of leprosy were divided into 2 groups of equal size ($n_{1,\;2}=20$): a group that participated in the exercise program, and a control group that did not exercise but did continue to engage in normal daily activities (including walking). The exercise group exercised for 60 minutes 2 days a week for 12 weeks. Static balance ability was measured by asking study participants to a one leg standing test: dynamic balancing ability was measured with a tandem walking test and a timed up-and-go test. The participants in the exercise program and the control group were tested before and after completion of the exercise program for comparison, and then divided according to their ability to feel sensory in the soles of their feet into the categories of normal sensory group: group with sensory loss in one foot: and group with sensory loss in both feet. The participants in the exercise program showed a positive, statistically significant difference in static balance compared with the control group (p<.05) as measured using the one leg standing test. Similarly, the participants in dynamic balance (p<.05) as measured using the tandem walking and timed up-and-go tests. Finally, these improvements were related to the severity of sensory loss in the soles of the feet for all study participants.

The purpose of this study was to investigate the effects of strengthening and stretching exercises on forward head angle and static dynamic balance ability. 21 adults with the forward head posture were participated in this study. Subjects were randomly assigned to strengthening exercise group I(n=11) and stretching exercise group II (n=10) respectively. Each group were underwent six intervention over the period of 2 weeks, each session lasting 30 minutes. During a preliminary examination, forward head angle and static dynamic balance were measured, and a post examination was conducted that involved same procedure as preliminary examination. There were significant differences in forward head angle after exercise in both groups. In the strengthening group, center of gravity total sway distances was significantly changed under all conditions. In the stretching group, center of gravity total sway distances was significantly changed when subjects had their eyes open while standing on an foam surface. There were significant changes in center of gravity sway velocities in the strengthening group under all conditions, and the same was true in the stretching group only when the subjects had their eyes open while standing on an foam surface. In the comparison between groups, eyes closed while standing on a firm surface was significantly different. There was a significant difference in dynamic balance of the stretching group when the subjects tilted their bodies forward, and there was a statistically significant difference between groups under the same condition. The results of this study suggest that forward head posture can be corrected through therapeutic exercise, and muscle strengthening exercise more effective in improving static balance of forward head posture more than stretching exercise.
