We compared prosthetic feet with different ranges of
motion at the ankle during stair negotiation to determine
work symmetry between the intact and prosthetic
limbs. All participants received standardized
functional training specific for each foot. We found
that the microprocessor-controlled prosthetic foot,
with active dorsiflexion, resulted in greater work
symmetry than conventional prosthetic feet during
stair ascent. While descending stairs, subjects employed
a similar movement strategy with all feet.
Prosthetic users who encounter stairs frequently may
benefit from a microprocessor-controlled foot.
