Inertial measurement unit compared to an optical motion capturing system in post-stroke individuals with foot-drop syndrome.

•Foot-drop refers to the inability to perform complete ankle dorsiflexion during gait after a stroke.•The data treatment algorithms from inertial measurement units are able to accurately capture kinematic and spatio-temporal gait parameters for post-stroke patients with foot-drop syndrome.•Kinematic and gait parameters obtained from inertial measurement units reflect patient performance.
