We examined gait in relation to aging in normal adults and the characteristics of walking in patients with equilibrium disorders. Thirty-five normal adults and 14 patients with equilibrium disorders were examined with eyes open. The measurement was performed mainly in the first three steps. Force plates were used to measure the centers of pressure. Step length, step width, cadence, walking speed, step length/body height, step width/step length, and LG/LS were analyzed.<BR>In the aged there was a marked shortness of step length, broadness of step width, slight decrease in cadence, marked slowing of walking, and increase in body sway as shown by LG/LS. There were no statistically significant differences between normal young and normal middle aged adults or between normal subjects and patients with equilibrium disorders except for those with active peripheral vestibular disorders. Key words: gait analysis, force plate, center of pressure
