Summary of the gait measures

Gait measures	Description
SPARC(-Acc, -V, -AP, −ML & -Gyro, -Yaw, −Roll, -Pitch)	Spectral arc length (unitless)
Harmonic Ratios (V, AP, ML)	Measure of step to step symmetry (unitless)
Mean Gait Speed	Mean gait speed (m/s)
Stride time mean	Mean stride time (s)
Stride time variability	Coefficient of variation of the stride time (%)

Note: Acc acceleration, V vertical, AP anteroposterior, ML medio-lateral, Gyro gyroscope
