Comparison between microprocessor-controlled
ankle/foot and conventional prosthetic feet during stair negotiation in people with unilateral transtibial amputation

Vibhor Agrawal, PhD, et al.

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.
