Anatomy of the psoas The psoas muscle is a long, ribbon-shaped muscle that starts at your lower back, and runs down through your pelvis where it joins the iliacus and connects to the top of your thigh bone (lesser trochanters). You can’t talk or work on the psoas muscle without also mentioning the iliacus. Together, these muscles are known as the iliopsoas muscle and they form the strongest of the hip flexor muscles while also supporting your spine. #anatomy | YOGABODY

Revisiting this diagram to talk about the psoas / QL relationship. Based on their similar attachment sites, weakness and/or tightness in one of the muscles will have an impact on the other despite their different muscle actions. This can have many implications for patients with pelvic, hip, or low back pain. #pelvicfloor #pelvichealth #pelvicfloorphysicaltherapy #pelvicfloorpt #pelvicfloorpta #pelvichealthnj #pelvichealthphysio #madisonnj | Pelvic Health NJ

The Psoas Major is a deep core stabilizer and one of the most powerful hip flexors in the human body. It originates from the lumbar vertebrae and inserts into the lesser trochanter of the femur, enabling hip flexion, external rotation, and lumbar spine stabilization. This muscle plays a critical role in walking, running, maintaining upright posture, and transferring forces between the spine and lower limb. Weakness or tightness in the psoas can lead to low back pain, pelvic imbalance, or gait dy
