Study Description

The aim of the study is to evaluate the effects of BoNT-A combining with overground exoskeleton robot for patients with post-stroke stiff-knee gait.

Stiff-knee gait (SKG) is a common gait pattern in patients after stroke, characterized by limited knee flexion (KF) during the swing phase of walking. Botulinum toxin A (BoNT-A) injection in rectus femoris muscle is considered the gold standard procedure to treat SKG.

Patients with this gait pattern would reduce walking speed, cause toe dragging, compromise the stability of walking, increase risk of falling, and interfere with daily activities. This randomized controlled trial will contribute to the accelerated refinement and development of efficient and effective treatment programs for patients with post-stroke spastic stiff knee gait. The Robot-assisted gait training (RAGT) has the potential to be an optimal adjunctive therapy following BoNT-A treatment. Combinations of BoNT-A and rehabilitation training are suggested to optimize the treatment effect for spasticity related disabilities.
