Is Limited Hip Extension Causing Your Low Back Pain?
Limited hip extension is a common but often overlooked contributor to low back pain. When the hip cannot fully extend, the body compensates by borrowing motion from the lumbar spine. Over time, this leads to excessive stress, fatigue, and chronic irritation of the lower back.
Lumbar Compensation and Excessive Extension
The hip joint is designed to generate extension. When it cannot, the lumbar spine is forced to extend more than it should, creating increased shear forces. This commonly occurs during walking, running, standing from a chair, stair climbing, and pushing off the back leg. Repeated lumbar hyperextension under load can irritate the facet joints, intervertebral discs, pars interarticularis, and nerve roots—key drivers of mechanical low back pain.
Altered Gait and Postural Changes
Restricted hip extension changes how you walk and stand. Stride length shortens, posture becomes more forward-leaning, and stress accumulates through the spine. This often results in increased anterior pelvic tilt, tight hip flexors (iliopsoas, re**us femoris, TFL), persistent lumbar lordosis, elevated paraspinal muscle tone, and underactive gluteus maximus. As a result, the lower back muscles remain overworked, leading to stiffness and ongoing discomfort.
Poor Load Transfer and Spinal Overload
The hips are meant to absorb and transfer force between the ground and the spine. When hip extension is limited, forces bypass the hip and load the lumbar spine directly. Over time, this increases the risk of disc irritation, overuse injuries, and chronic low back pain—especially in runners, active individuals, and those who sit for long periods.
Key Takeaway
If the hips can’t extend properly, the lower back will compensate. Restoring hip extension is essential for improving movement mechanics, reducing spinal stress, and achieving long-term, non-surgical back pain relief.
