Older adults’ lower-limb muscle power production throughout a full flight of stairs: Reliability and comparison between different stair models

Body-fixed sensors can measure power production throughout the different steps of a flight of stairs to assess different aspects of performance. This study investigated: 1) power production throughout a full flight of stairs; 2) if staircases with less or more steps can provide similar information; and 3) test-retest reliability of stair climbing power.
