Abstract
Understanding how extrinsic muscles generate motion at the joints of the human foot and ankle is critical towards both identifying the effects of injuries on locomotion and predicting the outcome of rehabilitation and surgery. Qualitative studies seeking to understand muscle function responsible for gait have been performed. However, quantification of the effects of individual muscle contraction on the distinctive joints of the foot and ankle has not yet been explored. In this thesis, a previously validated computational model of the foot and ankle has been expanded to enable simulation of the active contraction of ten of the twelve extrinsic muscles. CT-scans of 5 cadaver legs were used to develop the 50 subject-specific dynamic models used in this study. The complex response of the bones to simulated muscle contraction was solely a result of elastic ligament constraints and bone-on-bone contact. Muscle function was quantified at each joint by using measurements tracking the motion of each bone relative to its neighbors and compared to common descriptions observed in literature.
