iliopsoassenan

Iliopsoas is a composite muscle group located in the inner hip. It is formed by the joining of two muscles: the psoas major and the iliacus. The psoas major originates from the lumbar vertebrae, while the iliacus originates from the iliac fossa of the pelvis. Both muscles then merge and insert onto the lesser trochanter of the femur, the small bony prominence on the inner side of the thigh bone.

The primary function of the iliopsoas is to flex the hip, which is the action of bringing the thigh towards the abdomen. It also plays a role in flexing the lumbar spine and stabilizing the trunk. Because of its deep location and extensive involvement in movement, the iliopsoas can be affected by various issues, including muscle tightness, strain, or injury.

Tightness in the iliopsoas can contribute to postural problems, such as an anterior pelvic tilt, and can also lead to lower back pain. This muscle group is crucial for activities such as walking, running, kicking, and sitting. It is considered one of the most powerful flexors of the hip. Rehabilitation and stretching exercises for the iliopsoas are often recommended for individuals experiencing hip or lower back discomfort.
