Background: Limb-sparing surgery is important for treatment of soft tissue sarcoma, but resection of major neurovascular bundles and/or muscles in the lower extremities causes motor and gait dysfunction. This case report documents the effect of an ankle-foot orthosis on muscle strength and gait in a 52-year-old woman who had limbsparing surgery for soft tissue sarcoma that removed the common peroneal nerve and hamstring muscles (biceps femoris, semimembranosus, and semitendinosus).
Methods: The patient underwent knee flexor strength testing with and without the ankle-foot orthosis. Gait analysis was performed with and without the ankle-foot orthosis using a 3-dimensional motion analysis system, along with recording of the surface electromyogram and collection of ground reaction force data with a multicomponent force platform.
