| Definitions of gait parameters | |
| Parameter | Definition |
| Run duration | Time of finishing an entire run in second |
| Maximum area | The print area of paw when the braking phase turns into propulsion phase |
| Maximum intensity | Maximum pressure of paw contacting floor |
| Stride length | The distance between two consecutive travels in the same paw |
| Swing duration | The duration in seconds of no contact of a paw with the glass plate |
| Swing speed | The ratio of stride length to swing duration |
| Stance | The time duration in seconds of paws in contact with glass plate |
| Step cycle | The time in seconds between two consecutive initial contacts of the same paw |
| Duty cycle | The percentage of stance over the sum of stance and swing duration |
| Cadence | Steps per second in a trial |
| Base of support | Distance between fore limbs or hind limbs at maximum area |
| Initial dual support | The first time in a step cycle of a hind paw that the contralateral paw also makes contact with the glass plate |
| Terminal dual support | The second step in a step cycle of a paw that the contralateral paw also makes contact with the glass plate |
| Diagonal dual support | |
| Three-point support | |
| Four-point Support | The relative duration of simultaneous contacts of limbs with the glass plate |
| Step Pattern | Configuration of right (R), left (L), front (F) and hind (H) limbs |
| Alternate Aa: RF-RH-LF-LH; Ab: LF-RH-RF-LH | |
| Cruciate Ca: RF-LF-RH-LH; Cb: LF-RF-LH-RH | |
| Rotary Ra: RF-LF-LH-RH; Rb: LF-RF-RH-LH | |
| Regularity Index | The number of normal step sequence patterns relative to the total number of paw placements |
