Definition of the gait parameters recorded on the Tekscan Walkway System (Walkway User Manual v.7.02x, pp. 208–213)
| Variable | Definition |
|---|---|
| Speed (m/s) | Gait distance (from posterior heel of first stance to posterior heel of last stance) divided by gait time (time of first contact of first step to time of first contact of the last step registered on the sensor) |
| Peak vertical force (% of BW1) | The peak vertical force value reported as a percentage of the bird’s body weight |
| Impulse (% BW1/s) | The impulse value (force × time it acts over) reported as a percentage of the bird’s body weight impulse |
| Single support time (s) | The time the foot is in contact with the sensor, measured from the last contact of the opposing foot’s preceding stance to the first contact of the opposing foot’s next stance |
| Double support time (s) | Time over which the body is supported by both legs |
| Stance time (s) | The average time from first contact of the foot to last contact of the same foot |
| Stride length (cm) | Distance between the posterior heel points of two consecutive footprints of the foot in question (parallel to the line of progression) |
| Stride time (s) | Elapsed time between the first contacts of two consecutive footfalls of the foot in question |
1BW, body weight. Peak vertical force is named maximum force in the user manual.
