Stiff-knee gait in cerebral palsy: How do patients adapt to uneven ground?

Highlights • First study that showed adaptive mechanism to uneven surface condition in CP. • Patients with stiff-knee gait showed similar adaptability than healthy controls. • Patients with stiff-knee gait were able to flex their knee when it was necessary to prevent falling. • Patients with stiff-knee gait increased knee flexion although rectus femoris activity increased. • Training on uneven surface might be an option to improve stiff-knee gait.
