Figure Legend:
Hypothesized adaptation of the ankle moment versus ankle dorsiflexion curves. An adaptable ankle-foot mechanism should shift its set-point into dorsiflexion when walking uphill and into plantarflexion when walking downhill.

Figure Legend:
Prosthetic-side ankle flexion/extension curve for Subject A walking on the five surfaces with (a) the prototype and (b) his usual prosthetic ankle-foot system. Positive angles are for dorsiflexion whereas negative are for plantarflexion. Data for Subject A walking with the mechanism and with his usual prosthesis have been averaged for ten walking trials.
