Spatial Analysis - Gait up PhysiGait Lab User Manual

Foot-flat phase [%] is the portion of the stance where the foot is fully flat
on the ground.
Pushing phase [%] is the portion of the stance between the foot being flat
on the ground and the toe leaving the ground at take-off.

Spatial Analysis

Stride Length [m] describes the distance between two successive
footprints on the ground, from the heel of a foot to the heel of the same foot,
one cycle after.
Stride Velocity [m/s] is the forward speed of one cycle. See "Speed" in
essentials.
Peak Angle Velocity [deg/s] is the maximum angular velocity during the
swing phase, between max heel clearance and min toe clearance.
Measured by the gyroscopes, this parameter is a raw sensor measure which
is not subject to any calculation errors. It can be used as a robust asymmetry
measure.
Maximal Swing Speed [m/s] is the maximum forward speed of the foot
during swing. This speed is usually obtained around minimal toe clearance
and it is usually equal to more than3 times walking speed.
Strike Angle [deg] is the angle between the foot and the ground at heel
strike, on a vertical plane.
Lift off Angle [deg] is the angle of the foot at the end of the push phase,
just at take-off.
Swing Width [m] is the maximal lateral excursion of the foot during swing
phase. It is the maximum lateral distance between the forward path and the
real path of the foot.
3D Path Length [% stride length] is the length of the real path of the foot
during one cycle in 3D space, including both stride length and swing width.
