An integrated biomechanical analysis of normal stair ascent and descent

摘要: Three normal males of similar height and weight ascended descended a five step staircase with riser 22 cm tread 28 cm. EMG, force plate cine data were collected for the stride over second to fourth during each mode. Kinematic kinetic analyses integrated EMG yield an interpretation mechanics stair walking. Movement from one next involved simultaneous lifting horizontal translation body, showed specific phases progression. The extensor muscles about knee played dominant role in progression both modes coupled ankle plantar flexors. total lower limb pattern, called support moment, was highly correlated between subjects level Intra- inter-subject variability motor patterns also determined. greatest seen at hip, while stereotypic emerged all across 24 trials
