Swing [%] is the portion of the cycle during which the foot is in the air and

does not touch the ground. Normal swing is about 40% of gait cycle duration.

Loading phase [%] is the portion of the stance between the heel strike and

the foot being flat on the ground.

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.
