Walking and the Back
There are many signs and symptoms associated with leg length inequality that include: low back pain, uneven iliac crests, curvature of the spine, hip pain and recurrent sciatic pain. It is felt that a leg length deficiency of 3/16 of an inch to º of an inch is enough to contrite to increase the risk for low back pain. There are different methods which physicans can use to assess leg length.
Heel Spur: A heel spur refers to the degenerative outgrowth of bone along the bottom of the heel. A heel spur may or may not be painful. The presence of a heel spur indicates that there has been a pattern of abnormal biomechanical strain on the tissues of the bottom of the foot (plantar fascia). A painful heel spur will result in favoring of the limb with an abnormal shift of weight onto the non-painful leg during walking.
Heel Pad Atrophy: Heel pad atrophy occurs as part of the aging process. It occurs when the fat pad which cushions the heel become thinned. Atrophy of the heel pad provides less protection of the heel during the heel strike phase of gait and also results in less shock absorption at the heel during walking and other weight bearing activities. This can result in chronic weight-bearing heel pain.
High-Arched Foot: A high arch foot is often not flexible. There is usually less movement into pronation during weight bearing phase of walking. The foot is subsequently more rigid resulting in a harder heel strike. A high arched or supinated foot tends to be more rigid and stiff therefore less likely to adapt well when walking on various terrains. The high-arched foot is an inefficient shock absorber resulting in greater stress upon the knees, hips and low back.
