The biomechanics and functionality of the mid-foot of the feet are crucial to normal walking and running gait and biomechanics. The stability of the mid-foot of the foot is maintained by a number of factors, including the alignment of the bones, the ligaments, the muscles as well as the plantar fascia. One of several major muscles in the functional support of the mid-foot of the feet are the posterior tibial muscle. It is a strong muscle that is in the leg. The tendon of this muscle passes on the inside of the ankle joint and attaches below the bones that comprise the mid-part of the arch of the foot, so this particular muscle is really necessary for supporting the mid-foot. In many people, the posterior tibial muscle seems to lose it ability to stabilize the foot, causing a disorder referred to as Posterior Tibial Tendon Dysfunction.
This condition typically commences with a moderate ache in the midfoot or inside of the ankle joint and the arch of the foot progressively collapses and the rearfoot rolls inwards. This is all because of the muscle being unable to do its job effectively. If therapy is not implemented, then the pain and deformity gets worse. In its end stages it usually is very disabling and painful. It eventually has a substantial affect on total well being and also the ability to walk. It is extremely fatiguing as a lot of energy is necessary to walk with this problem.
Since the long term outcomes of this disorder can be so debilitating, it is very important that it's diagnosed as early as possible and therapy begun. The lengthier the delay the harder it is to manage. During the early stages, the only real satisfactory intervention usually are very firm or rigid foot orthotics. They have to be hard as the forces which are flattening the arch are so high that they need to be resisted. A less rigid orthotic will do nothing. A high top hiking or basketball like footwear or boot is also helpful at stabilising the rearfoot. If this is not sufficient then more complicated ankle supports are the next intervention. If this fails or the therapy is started too late, then surgery is often the only suitable treatment at this late stage.
