Biomechanical analyses of stair-climbing while dual-tasking

摘要: Stair-climbing while doing a concurrent task like talking or holding an object is common activity of daily living which poses high risk for falls. While biomechanical analyses overground walking during dual-tasking have been studied extensively, little known on the biomechanics stair-climbing dual-tasking. We sought to determine impact performing cognitive motor stair-climbing. hypothesized that will greater stair climbing performance compared and this be higher-level step. Ten healthy young adults performed 10 trials each under four conditions: ascending only, subtraction serial sevens from three-digit number, carrying empty opaque box ascending, random number box. Kinematics (lower extremity joint angles minimum toe clearance) kinetics (ground reaction forces moments powers) data were collected. found impacted but not kinematics The effect ascent also seemed vary based different phases stance seem as one climbs higher. Overall, results current study suggest association between executive functioning (like gait) becomes stronger level complexity increases.
