Biomechanics is the name of the science behind the study of body movement which is vitally important when assessing lower limb and foot function. Discomfort or pain within the feet is often connected with an area of foot function being compromised. Such changes can occur following a sports injury, trauma or simply changes in foot function that occur over time. Changes in foot biomechanics may also affect several other areas of the body. For example, knees, hips, spine and shoulders are all vulnerable to biomechanical changes resulting in discomfort or pain should problems within the feet persist.
