Reflex Excitability in Post-stroke Stiff-Knee Gait

United States60 participantsStarted 2021-06-11

Plain-language summary

The purpose of this study is to examine the reflex excitability of the rectus femoris in individuals with and without post-stroke Stiff-Knee gait. We use electrical stimulation of the peripheral nerve innervating the rectus femoris for a well-controlled reflex stimulus. We are investigating whether reflex excitability of the rectus femoris correlates with gait kinematics.
