Use musculoskeletal modeling to determine how robost unimpaired and crouch gait are to weakness of individual muscle groups.

Individuals with cerebral palsy (CP) who walk in a crouch gait often receive strength training as part of their therapy. An underlying assumption is that these individuals do not have adequate muscle strength to walk in an upright posture, and strengthening weak muscle groups will enable these individuals to improve their knee extension. However, outcomes from strength training programs for individuals with cerebral palsy and crouch gait are inconsistent. The purpose of this project is to determine how much strength is required to walk in a crouch gait and compare this to unimpaired gait. Identifying which muscle groups require more or less force to maintain a crouch gait versus an upright gait can provide guidance for designing effective strength training programs for individuals with CP who walk in a crouch gait.
