    摘要: "Stair locomotion has been used in the rehabilitation of the lower extremity as a motor performance test
    and multi-joint exercise. Controversies exist regarding joint loads during stair locomotion. The
    purposes of the study were to investigate the three-dimensional kinetics of the lower limb joints during
    stair locomotion, and to compare them with those during level walking. Ten normal young adults walked,
    and ascended and descended stairs in a gait laboratory while kinematic and kinetic data were collected and
    analyzed. The results showed that the intersegmental resultant forces at the joints during the activities
    were generally similar in pattern but the force magnitudes, moments and angular impulses were
    significantly different. The general impression that the loads in the lower limb were larger during stair
    descent than stair ascent only holds for certain kinetic variables. Most of the peak joint moments and
    angular impulses over the entire stance phase were bigger during stair ascent than descent. The study
    provides a complete knowledge of the three-dimensional loading patterns at and dynamic functions of the
    lower limb joints during level walking and stair locomotion. It will be helpful for the planning and
    evaluation of treatment programs for patients with neuromusculoskeletal pathologies in the lower
    extremities."
