Lumbo-Sacral Pain (Lower Back Pain)

Muscular tightness in the Lumbo-sacral region causes lower back pain.


The patient will complain of a dull ache and stiffness in the lumbar region. Standing for long periods or sitting in the same position may worsen the pain.


Bilateral excess subtalar joint pronation internally rotates the tibial and femoral shafts. This can lead to an anterior tilt of the pelvis and a forward shift of the body’s centre of gravity, resulting in increased lordotic curvature and compensatory muscular tightness of the Lumbo-sacral region.

The upper body (thoracic region) commonly develops a secondary kyphosis curvature. Unilateral excess subtalar joint pronation lowers the vertical distance of the foot to the ground, creating a functional short leg and hip malalignment.
