The dysfunction and function of the mid-foot of the foot is crucial to normal walking gait and biomechanics. The support of the mid-foot of the foot is achieved by a number of things, including the alignment of the bones, the ligaments, the muscles as well as the plantar fascia. One of several essential muscles in the functional stability of the arch of the feet are the posterior tibial muscle. It is a strong muscle that is in the lower leg. The tendon of this muscle passes around the medial side of the ankle joint and attaches below the bones that comprise the mid-part of the arch of the feet, so this particular muscle is so important for supporting the arch. In many individuals, the posterior tibial muscle seems to lose it capability to support the foot, resulting in a disorder referred to as Posterior Tibial Tendon Dysfunction .
This problem usually commences with a mild discomfort in the arch or inside of the ankle joint and the mid-foot of the feet progressively flattens and the rearfoot rolls inwards. This is all due to the muscle being unable to do its job correctly. If therapy is not started, then the pain and disability progresses. In its later stages it can be very debilitating and painful. It eventually has a considerable affect on total well being and the ability to walk. It is very exhausting because so much energy is necessary to walk with this problem.
