The foot can have a direct effect on the lower limb and the way in which it functions.
A foot which does not give sufficient shock absorption at heel strike or one which does not give efficient leverage at the toe off stage of a step can lead to lower limb injury. This is especially significant in active people involved in sport as during the running gait cycle ground reaction forces are increased.
Some conditions commonly associated with poor foot function are plantar fasciitis, Achilles tendinitis, iliotibial band syndrome, shin splints, over use syndromes and stress fractures. Poor lower limb alignment will also contribute significantly to hip, knee and back pain.
A podiatric biomechanical assessment will help to identify poor foot function and associated lower limb malalignment . If required, orthotic insoles can be prescribed to enable the foot to function nearer to its ideal. The foot in its ideal position should allow sufficient pronation for shock absorption and sufficient supination for efficient toe off and prevent abnormal rotational forces being transmitted into the lower limb.
Orthotic insoles can help to prevent injury and also to help in the treatment of chronic lower limb injury, by reducing over work placed on muscles, tendons and ligaments as they try to stabilize the foot.
