The effects of simulated leg length difference on Surface EMG activities of back muscles and gluteus maximus hamstring muscles during forward bending
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.
