Prosthesis geometry and behaviour limit the footwear options available to women. Using a commercially available prosthetic foot that permits user-alignment to accommodate shoes with different heel heights, we investigated the effect of footwear on gait kinematics, with and without adjustment for differences in heel-forefoot differential. Three women with transtibial amputation walked at a self-selected pace, first in an athletic shoe (prosthetist-aligned; baseline condition), then (i) in a flatter shoe without realigning the prosthesis, and (ii) in flat and heeled shoes following user re-alignment. Kinematics in each condition were compared to baseline. Baseline gait patterns were highly variable across participants. Gait was slower in comparison to baseline in all conditions, but movement compensations varied across participants. An increased lower limb extension tendency was evident with the misaligned prosthesis. With user re-alignment to accommodate the shoe there were fewer deviations from baseline, however kinematic differences remained in both the flat and heeled shoes. The user-alignment feature of the prosthetic foot reduced the effect of a change in footwear on kinematics, and permitted walking in heeled shoes when it might otherwise not be possible. Persistence of some deviations suggests differences in walking task demand remained despite adjustment.Implications for rehabilitationPermitting prosthesis users to don footwear of choice may improve body image, well-being and quality of life following amputation.Prosthetic feet that permit user ankle adjustment can reduce gait deviations associated with a change in footwear heel height, although kinematic adaptations are individual.
