Biarticular Muscles Influence Postural Responses: Implications For Treatment Of Stiff-Knee Gait, Ashley Elizabeth Clark
Biarticular Muscles Influence Postural Responses: Implications For Treatment Of Stiff-Knee Gait, Ashley Elizabeth Clark
Masters Theses
Stiff knee gait is a prevalent and troublesome movement disorder among children with cerebral palsy, where peak knee flexion is diminished during swing phase. Rectus femoris transfer surgery, a common treatment for stiff-knee gait, reattaches the distal tendon of this biarticular, or two joint, muscle to a new site, such as the sartorius insertion on the tibia. Biarticular muscles play a unique role in motor control. As a biarticular muscle, rectus femoris may offer unrecognized benefits to maintain balance. This study uses musculoskeletal modeling and simulation to investigate the role of this biarticular muscle on balance recovery following support-surface translations. …
