Muscle-tendon Interaction in the Spastic Sural Triceps During Gait

This project aims to study the mechanical behavior of the muscle-tendon unit (MTU) of the gastrocnemius medialis (GM) and the Achilles tendon (AT) in post-stroke and spinal cord injured (SCI) patients compared to a healthy population, focusing on the variations in muscle and tendon length during the stance phase of the gait cycle. The primary objective is to assess the respective contributions of the GM and AT lengthening in the MTU during walking. Inclusion criteria include adult post-stroke and post-SCI patients with voluntary motor function and some walking capacity. Methods include ultrasound measurements and 3D gait analysis.
