Instrumented staircase for ground reaction measurement.
A staircase was developed to record ground reactions during stair climbing at different slopes (inclinations). Each step is instrumented with six strain-gauge-based force transducers which allow the measurement of three-dimensional ground reaction force and moment as well as the centre of pressure (COP) location. A specific sensor arrangement permits accurate recording, especially of the COP location. The overall design of the staircase and details of a single instrumented step are presented. Static and dynamic characteristics have been evaluated by different experimental procedures. Preliminary results of ground reaction forces are shown.
