Abstract Summary
Understanding changes in muscle synergies and joint moments when changing from normal walking to running is an important aspect of rehabilitation. This study performed a comparison of joint moments and muscle synergies for three activities viz. walking, fast walking, and running. Gait data was collected in the motion analysis lab for ten healthy adult volunteers and lower limb joint moments were quantified using an inverse dynamics OpenSim modelling framework. A previously established full body musculoskeletal model was customized and used in this study. Results corroborated well with the literature and revealed how a transition from walking to running occurs in each phase of the stance period. Future work is dedicated to understanding muscle synergies associated with three activities.
