Design and development of ankle-foot prosthesis with delayed release of plantarflexion

Michael Mitchell, MSc, et al.

A mechanism was built to hold the energy stored in an artificial foot and delay its return until later in the stride. The mechanism was tested with two volunteers, who reported that they could feel a difference in the delays. Some delays felt more comfortable than others, but the subjects were not consistent in their choices. The increased mass of the device made the general kinematics more similar to the nondisabled population. The mechanism not only delayed the release but also slowed the release of the energy, creating a longer, slower push, which was felt by the subjects.
