In this study, the area where the iliac muscle and psoas major muscle are visualized on the surface was examined using ultrasound imaging system. The site where the iliac muscle was visualized on the surface was 0–1 cm lateral at 1 cm below the anterior superior iliac spine (ASIS), 0–2 cm lateral at 2 cm below the ASIS, 1–2 cm lateral at 3 cm below the ASIS, 2–3 cm lateral at 4 cm below the ASIS, 2–4 cm lateral at 5 cm below the ASIS, 3–4 cm lateral at 6 cm below the ASIS, 3–4 cm lateral at 7 cm below the ASIS. The psoas major muscle was not visualized on the surface. This result suggests that the activity of the iliac muscle can be examined using surface electromyography.
