Table 1 Gait Spatiotemporal Parameters (SPTs), measurement units, and definitions
Variables | Units | Definitions |
|---|---|---|
Cadence | Step/minute (step/min) | Number of steps per minute |
Gait speed | Meter/second (m/s) | The forward speed of the subject, measured as the forward distance traveled during the gait cycle divided by the gait cycle duration. |
Stride length | Meters (m) | The forward distance traveled by a foot during a gait cycle. |
Double support time | % GCT | The percentage of the gait cycle in which both feet are on the ground. |
Swing time | % GCT | The percentage of the gait cycle in which the foot is not on the ground. |
Foot strike angle | degrees | The angle of the foot dorsiflexion at the point of initial contact. The pitch of the foot when flat is zero and positive when the heel contacts first. |
Stride time variability | % | The percentage of each participant’s standard deviation of stride time is divided by the same parameter mean value. |
