The ankle-foot joint is under continuous stress. If your ankle is becoming painful, the problem may be due to the pressure transmitted from the ankle and then to the foot. The foot has a very limited area of support compared to the body weight and the position of the center of gravity. Therefore the ankles can be prone to distortion or sprain, resulting in very limited movement.
The foot is a strong and complicated structure: it is made up of 26 bones, connected in 33 joints, and strengthened by more than 100 ligaments. Body weight is transmitted to the foot by the ankle or by tibiotarsal joint. The tibiotarsal joint is a bone-ligament complex with the shape of a mortar: the tibia and fibula with their two malleoli surmount and wrap around the upper part of the astragalus, which transfers the pressure to the other bones of the foot.
If the ligaments are strained, the tough fibrous cords can break, and as a result this can lead to more severe distortive injuries. An increase of the movement within the joint will improve resultant instability.
