Outline of Final Research Achievements

The purpose of this study was to evaluate activity of the psoas major using fine-wire electromyography and MR diffusion-weighted imaging quantitatively, and to examine effective exercises for strengthning the psoas major. The results showed that the activity of the psoas major was significantly greater at deep hip flexion phase during sit-up and straight leg raise exercises. Additionally, elbow-toe exercise produced significantly greater acitivity in the psoas major than other bridge exericses.
In conclusions,hip flexion movement at deep hip flexion position, elbow-toe, elbow-knee exercise may be effective for strenghtning the psoas major.
