Description of the spatio-temporal parameters (STP).
| Parameter | Description |
|---|---|
| Step Length (m) * | Distance between the CA marker positions of the left and right foot projected on the ground at two consecutive contralateral ICs |
| Stride Length (m) | Distance between the CA marker positions of one foot projected on the ground at two consecutive ipsilateral ICs |
| Step Width (m) * | Orthogonal distance between the line of the CA marker positions of one foot projected on the ground at two consecutive ipsilateral ICs and the CA marker position of the contralateral foot at the contralateral IC |
| Swing Width (m) * | Minimal distance between both CA markers during the swing phase |
| Step Time (s) | Period between two consecutive ICs of the left and right foot |
| Stride Time (s) | Period between two consecutive ICs of the ipsilateral foot |
| Cadence (steps/min) | 60 divided by step time |
| Single Limb Support (s) | Period between contralateral TC and contralateral IC |
| Double Limb Support (s) | Stride time minus Single limb support |
| Stance Time (s) | Period between IC and TC of one foot |
| Swing Time (s) | Period between TC and IC of one foot |
| Speed (m/s) | Stride length divided by Stride time [4] |
An asterisk * marks the STP that require the spatial information of both feet for the calculation.
