Custom-fitted carbon fiber AFOs are commonly prescribed for foot drop and transmetatarsal amputations. The application for foot drop addresses weakness of the dorsiflexors during swing phase, while transmetatarsal amputation requires accommodating for weak plantarflexors during stance phase to prevent drop-off, an excessive drop of the height of the body’s center of mass. Selecting the right AFO is possible through a comprehensive evaluation of your patient that includes his or her stride length, weight, and gait pattern. This article evaluates these gait characteristics and their importance in selecting an AFO that will optimally benefit your patient.
