This study was to investigate the effect of muscular activation in lubar muscles according to muscle strength imbalance of left and right lower limbs. The ten young women who have muscle strength difference in left and right leg were recruited through isokinetic joint torque test. They walked on the treadmill during one minute with velocity, direction and slope protocol. We measured muscular activity in vastus medialis, tibialis anterior, gastrocnemius, lliocostalis lumborum using bagnoli-8ch system(Delsys. Co., USA). The results showed significantly that the bigger velocity and slope level was, the bigger muscular activity differences of lumbar muscle were. But there did not show significantly in the result of gait direction. The bigger muscle imbalance of lumbar muscle occurred during walk with increased velocity and slope caused the complementary muscle activation with increased workload. This study could apply to fundamental research of chronic disease treat in muscle imbalance.
