How can lower extremity biomechanics contribute and how can we reduce this very common problem?
A thorough biomechanical exam will often lead to the discovery that mechanical issues in the feet, ankles knees and hips are contributing to extra strain on the low back. Here are 2 very common biomechanical causes for low back pain.
- Flat feet pull the knees and thighs into an internally rotated position. This position puts strain on the hips and leads to an increase in the curvature to the low back. Supporting the arches externally rotates the knees and reduces the curvature of the lumbar spine.
- Most of us have a difference in the length of our legs. This creates an angle to the pelvis for which the low back is forced to compensate. Low back pain that gets worse with standing and walking should be evaluated with respect to a limb length discrepancy. Many times a simple lift can make a huge difference!
