摘要：
Devices, methods, and systems for an articulated ankle-foot orthosis with a selectively retractable stop are presented. The orthosis includes at least one of a foot mold, a shank mold, a forefoot sensor, a heel sensor, a stop, and a connecting mechanism. The stop is positioned between the foot mold and the shank mold, and the stop is selectively retractable between a closed position and a generally opposing open position that allows plantar flexion of the foot mold during the stance phase of a typical human gait cycle. The connecting mechanism is configured to move the stop from the closed position to the open position in response to a signal from the heel sensor indicating a heel-strike event. The connecting mechanism is also configured to move the stop from the open position back to the closed position in response to a signal from the forefoot sensor indicating a toe-off event.
