Subacute Stroke Gait biomechanics data

The spatiotemporal parameters were measured using Steadys system (Neurosoft, Ivanovo, Russia). Seven inertial sensors were fixed on participant’s pelvis, thighs, ankles, and feet. Each sensor recorded spatiotemporal parameters, joint amplitudes and functional EMGs of lower limb muscles.
All participants walked a 10-meter distance, making turns at the end of the distance, and continued walking without stopping until 30–40 gait cycles were accumulated for each leg. The Steadys automatic algorithm discarded steps at the beginning and end of walking, acceleration and deceleration of walking speed, as well as any other unsteady steps (loss of balance, stumbles), leaving only well-recorded gait cycles. As a result of registration, a standard report was obtained containing the spatiotemporal parameters of the gait cycle for each leg, sagittal kinematic parameters for hip, knee, and ankle joints, as well as profiles of the electrical activity of four muscles: quadriceps femoris, hamstring, tibialis anterior, and triceps surae.
