The effect of ankle position on plantar pressure in a short leg walking boot

Short leg walking boots have been shown to be an effective alternative to total contact casting for the reduction of plantar pressure. Conventional theory indicates that placing the ankle in different positions may affect the plantar pressure and ultimately the healing time for a plantar ulcer. This study attempted to determine the changes in plantar pressures due to alterations in the position of the ankle angle in a walking boot. Thirteen healthy subjects were recruited and tested with an insole pressure measurement system. The result demonstrated that small changes in ankle position in dorsiflexion or plantarflexion have a significant impact on resulting forefoot and hindfoot plantar pressures while walking in a prefabricated boot.
