Table 1 Definitions of gait parameters

From: Quantitative assessment of gait and neurochemical correlation in a classical murine model of Parkinson’s disease

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
