The initiation of gait
RA Mann, JL Hagy, V White and D Liddell
The initiation of gait was studied utilizing electromyography, force-plate
data, measurements of walking velocities, and ranges of motion of joints,
all of which demonstrated that gait is initiated by the body becoming
unbalanced in such a way as to permit a subject to pick one foot the ground
in order to take the first step. The subsequent transition of the body to
the steady gait pattern occurs rapidly over a period of appproximately
three steps. This transition involves rapid changes in the measured forces
and activities of the muscles of the lower extremity and the motion of the
joints reflects these changes.
