Iliopsoas

The iliopsoas is a major muscle group in the human body, primarily responsible for hip flexion and, to a lesser extent, external rotation. It comprises two distinct muscles: the psoas major and the iliacus. The psoas major originates from the lumbar vertebrae and connects to the femur. The iliacus originates from the iliac fossa of the pelvis. Their combined action is crucial for activities like walking, running, and lifting the legs. Weakness or dysfunction can lead to lower back pain, hip pain, and difficulty with these everyday movements. This muscle group also plays a key role in maintaining posture and core stability.
