The dysfunction and function of the mid-foot of the feet are essential to normal walking and running gait and biomechanics. The stability of the arch of the foot is achieved by a number of things, for example the shape of the bones, the ligaments, the muscles as well as the plantar fascia. One of many important muscles in the dynamic support of the mid-foot ( arch ) of the feet are the posterior tibial muscle. This is a powerful muscle that is in the leg. The tendon of this muscle passes along the medial side of the ankle joint and attaches below the bones that make up the mid-part of the arch of the foot, so this particular muscle is really essential for stabilizing the arch. In some individuals, this muscle seems to lose it capability to stabilize the feet, causing a condition referred to as Posterior Tibial Tendon Dysfunction or adult acquired flat foot.
This problem generally commences with a mild ache in the midfoot or inside of the ankle joint and the mid-foot ( arch ) of the feet gradually collapses and the rearfoot rolls inwards (pronates). This is all as a result of the muscle being unable to do its job properly. If treatment is not implemented, then the pain and disability gets worse. In its later stages it usually is quite disabling and painful. It ultimately has a significant impact on total well being and also the ability to walk. It is quite fatiguing because a lot of energy is required to walk with this problem.
As the long term outcomes of this disorder may be so debilitating, it's important that it must be caught as quickly as possible and treatment started. The lengthier the delay the more difficult it is to deal with. During the early phases, the only real adequate intervention are usually very hard or stiff foot orthoses. Weather resistant be firm as the forces which are lowering the feet are so high that they must be opposed. A softer support will do nothing. A high top trekking or basketball type footwear or sneaker is also helpful at supporting the ankle joint. If this isn't adequate then more complicated ankle braces will be the next intervention. If this fails or the treatment is started far too late, then surgery is actually the only suitable intervention at this stage.
