Stride length

Stride length, distance between two consecutive heel contacts, averaged for left and right side. Normalized for height (% of subject height)

Stride velocity

Stride velocity, (% of subject height/s)

Cadence

Stepping rate (Steps/min)

Cycle time

Gait cycle time (GCT), duration of a complete gait cycle (s)

Double support

Double support, percentage of gait cycle with both feet on ground (% of GCT)

Swing time

Average percentage of a gait cycle that either foot is off the ground (% of GCT)

Stance time

Average percentage of gait cycle that either foot is on the ground (% of GCT)

Shank RoM

Shank range of motion, average of left and right (degrees)

Shank velocity

Peak (95%) shank angular velocity, average of left and right (degrees/s)

Arm RoM

Arm swing range of motion, average of the left and right sides (degrees)

Arm velocity

Peak (95%) arm angular velocity, average of left and right (degrees/s)

Trunk hor RoM

Trunk sag RoM

Range of motion of the trunk in the sagittal plane (degrees)

Trunk front RoM

Range of motion of the trunk in the frontal plane (degrees)

Trunk hor velocity

Peak angular velocity of the trunk in the horizontal plane (degrees/s)

Trunk sag velocity

Peak angular velocity of the trunk in the sagittal plane (degrees/s)

Trunk front velocity
