Prosthetic alignment is important for walking function and walking comfort in people with a transtibial amputation (TTA). Prosthetic alignment is defined as the position of prosthetic parts relative to the body and to each other. A suboptimal alignment decreases stability and increases energy use during walking. Therefore, finding the optimal alignment is an important aspect of rehabilitation. Shoe heel height is considered to influence prosthetic alignment, walking comfort and gait symmetry in people with a TTA. Unfortunately, research on the effect of heel height is scarce and no evidence is available on the effects of variations smaller than 20 mm. However, these small heel height variations between store-bought shoes are often overlooked by people with an amputation and may cause secondary musculoskeletal problems in the long term. To increase the knowledge on this topic, this study aims to examine the effects of small increases in heel height on gait symmetry in people with a TTA and healthy individuals. It was expected that higher heel height would cause more asymmetry in gait and lower walking comfort. People with a TTA were expected to be affected more by heel height changes than healthy individuals.
