Instrumented stairs

BPID: 889 Instrumented stairs are necessary to capture objective ground truth data on stair ascent, descent, turning, weight transfer, step timing, and transitional movements that commonly occur in real-world home and community environments but cannot be adequately measured with level walking systems alone. This equipment will support validation of advanced human-movement algorithms by providing detailed, high-fidelity measurements during functional mobility tasks that are critical for assessing balance, fall risk, mobility limitations, and safe navigation in everyday built environments.
