A self- developed speed measurement system using two light barriers was also integrated in the setup to allow the measurement of gait velocity and ensure a standardized measurement procedure. The system directly displays the velocity in meters per second and works continuosly in both walking directions.

To allow the measurement of ground reaction forces during stair walking, a special staircase element was constructed. This element can be mounted directly on one of the force plates and together with the staircase of the Rehabilitation Center Weißer Hof builds the final staircase that will be used during the whole biomechanical study.
