However, to walk properly your foot requires some upward movement. As a result, the ankle tries to compensate for this decrease in upward mobility by increasing the mobility at the subtalar joint. This causes a lowered arch, and the ankle and foot becomes less stable. This abnormal and excessive stretching on the foot and ankle can increase the tendency to sprain the ankle. To prevent such a cycle of bleeding, swelling, injury and joint destruction, it is important to regularly exercise the muscles around the foot and ankle with strengthening and mobility exercises.
Strong muscles protect the joint and decrease the chance of injury.
Adequate joint mobility is also crucial in protecting the joint. In addition, strong muscles and adequate joint mobility prevent lowering of the foot's arch. You should consider wearing foot orthotics if your arches have already dropped somewhat because of repeated joint bleeds. These are semi-rigid devices put in a shoe to help keep the foot in a neutral position that enables the ankle to function optimally. In addition, anyone with haemophilia should always wear supportive shoes to protect his ankles.
