The development of the biomechanical measurement setup is constantly moving forward. A proper staircase construction was acquired from the Rehabilitation Center Weißer Hof in Klosterneuburg and will be used for all upcoming gait analyses at the Biomechanics Laboratory of the USZ Vienna. The first staircase element will be placed directly on one of the force plates to measure the ground reaction forces of the first step on the staircase. Also the Cleveland Clinical Marker Set was implemented into the setup in cooperation with the orthopedic hospital Speising.
