步态的启动进行了研究，利用肌电图，力板数据，步行速度和关节的运动范围的测量。所有这些都表明，步态是由身体变得不平衡以允许受试者将一只脚从地面抬起以迈出第一步的方式启动的。随后身体向稳定步态模式的转变在大约3步的时间段内迅速发生。这种转变涉及下肢肌肉的测量力和活动的快速变化;关节的运动反映了这些变化。
The initiation of gait was studied utilizing electromyography, force-plate data, measurements of walking velocities and ranges of motion of joints. All demonstrate that gait is initiated by the body becoming unbalanced in such a way as to permit a subject to pick one foot off the ground to take the 1st step. The subsequent transition of the body to the steady gait pattern occurs rapidly over a period of approximately 3 steps. This transition involves rapid changes in the measured forces and activities of the muscles of the lower extremity; the motion of the joints reflects these changes.
