List of Studied Gait Parameters

Parameters	Units	Explanation
Time to gait initiation	S	Time elapsed between verbal instruction/lighting cue to begin walking and initiation of first step (any movement)
Velocity	cm/s	Distance traveled divided by ambulation time
Cadence	steps/min	Step rate, defined as the average number of steps taken per minute
Stride length	cm	Distance between heel centers of two consecutive footfalls of the dominant leg
Stride time	S	Time elapsed between first contact of two consecutive footfalls of the dominant leg
Stride velocity	cm/s	Stride length divided by stride time
Stance time	S	Time elapsed between first contact and last contact for a single footfall of the dominant leg
Swing time	S	Time elapsed between last contact of the dominant leg footfall and first contact of the next dominant leg footfall
Base of support	cm	Distance between the heel center of the dominant foot and the line of progression created by two subsequent heel strikes of the nondominant leg
Double support % cycle time	%	Percentage of stride time during which both feet are contacting the ground
