This study was to investigate the balancing and clinical abilities trunk muscle stabilization exercise and trunk muscle resistive exercise of stroke patients having surface changes in balance of body. The subjects of this study were 30 stroke patients(15 males and 15 females) that three times a week for 12 weeks at the same time point and with the same amount of exercise. They were separated into two groups and did reinforcing exercise on trunk muscle stabilization exercise and trunk muscle resistive exercise for three times a week for twelve weeks. It were measured balancing ability, they performed functional standing balance test, functional forward arm stretching test. performance-oriented mobility assessment, berg balance scale. The balancing exercises were modified from preceding studies and consisted of 6 difference exercises. The functional standing test with open and close eyes and performance-oriented mobility assessment, the trunk muscle stabilization exercise group and the trunk muscle resistive exercise group improved significantly. The forward arm stretching was test the trunk muscle stabilization exercise group more improved. This study found that the balancing exercise on trunk muscle stabilization exercise was more effective than trunk muscle resistive exercise for stroke patients. Thus, trunk muscle stabilization exercise has more positive effects on the improvement of balancing abilities of stroke patients.

Purpose This study evaluated the effects of bridge exercise on trunk core muscle activity with respect to sling height and hip joint abduction and adduction. Methods 30 healthy adult males participated. In the bridge exercise, the height of the sling was set low or high during hip joint abduction and adduction. Electromyography was used to compare the differences between the muscle activities of the transverse abdominis, rectus abdominis, and erector spinae muscles. Results The muscle more activities of the transverse abdominis, rectus abdominis, and erector spinae were significantly higher in Hip adductor position. The muscle activities of the transverse abdominis, rectus abdominis were significantly higher in the high sling position. Especially, A high activity in the transverse abdominis muscle was interaction in abduction and adduction of hip, high sling position. Conclusion These findings suggest that the activities of the abdominal and trunk muscles should put adduction of hip and the activities of the abdominal muscle have to make sling position high during bridging exercises with sling.
