Description of DigiGait system parameters relevant to nerve regeneration

Index	Meaning	Units	Definition
Swing duration	Swing duration	Milliseconds	Time duration of the swing phase (no paw contact with belt)
% Swing	Percentage of stride in swing	Percentage	Percentage of the total stride duration that the paw is in the air
Braking duration	Braking duration	Milliseconds	Time duration of the braking phase (initial paw contact to maximum paw contact; commencing after the swing phase)
% Braking	Percentage of stride in braking	Percentage	Percentage of the total stride duration that the paw is in the braking phase
Propulsion duration	Propulsion duration	Milliseconds	Time duration of the propulsion phase (maximum paw contact to just before the swing phase)
% Propulsion	Percentage of stride in propulsion	Percentage	Percentage of the total stride duration that the paw is in the propulsion phase
Stance duration	Stance duration	Milliseconds	Time duration of the stance duration (paw contact with belt); stance duration is equal to the sum of braking duration and propulsion duration
Stance width	Width between both forelimbs or both hind limbs	Centimeters	The perpendicular distance between the centroids of either set of axial paws during peak stance
Stance width CV	CV of stance width	Percentage	The SD of the stance width for the set of strides recorded (reflecting the dispersion about the average value)
Paw area	Paw area	Square centimeters	The area seen by the camera and reported at the time corresponding to peak stance (e.g., maximal paw area)

CV, coefficient of variation.
