Spatio-temporal gait parameters.

Temporal Measures
Variable	Description
Gait Cycle Time (GCT) [s]	Defined as the time between two successive heel strikes of the same foot.
Stance Time [s]	The amount of time a foot is in contact with the ground within a single gait cycle. It is the time between the heel-strike and the successive toe-off of the same foot.
Stance Phase [%]	Stance time expressed in percentage of the GCT.
Swing Time [s]	Duration of the swing phase, in which the foot is not in contact with the ground. It is calculated as the time between the toe-off and the successive heel strike of the same foot.
Swing Phase [%]	Swing time expressed in percentage of the GCT.
Single Support [%]	Part of the GCT in which a single foot is in contact with the ground. It is the time between the toe-off of the opposite foot and the successive heel-strike of the opposite foot, expressed in percentage of the GCT.
Double Support [%]	Part of the GCT in which both feet are in contact with the ground. It is the time between the heel-strike of a foot and the successive toe-off of the opposite foot, expressed in percentage of the GCT.
Cadence [steps/min]	Number of steps per minute.
Spatial Measures
Variable	Description
Stride Length [m]	Distance covered during GCT.
Stride Velocity [m/s]	Defined as the ratio between Stride Length and GCT.
