Table 1. Gait parameters recorded by GAITRite® and FeetMe® Monitor devices.
| Variables (units) | Side | Definition | Decision for analysis | Range |
|---|---|---|---|---|
| Primary Endpoint | ||||
| Velocity 1 and 2 (cm/sec) | NA | It was obtained after dividing the distance traveled by the ambulation time. Velocity 1 was recorded directly from the device. Every patient had more than one velocity, therefore the velocity 2 is the mean for all recorded velocities. | NA | 0–200 |
| Secondary Endpoints | ||||
| General Parameters | ||||
| Ambulation time (sec) | NA | GAITRite®: It is the time elapsed between the heel strike of the first footprint and the heel strike of the last footprint. FeetMe®: It is time elapsed between the first heel strike of the first stride and the second heel strike of the last stride. |
NA | 0–200 |
| Cadence 1 and 2 (steps/min) | NA | The number of steps within a minute. Cadence 1 was recorded directly from the device. Every patient had more than one cadence, therefore the cadence 2 is the mean for all recorded cadences. | NA | 0–200 |
| Spatial Parameters | ||||
| Stride length (cm) | Left | It is measured on the line of progression between the heel points of two consecutive footprints of the same foot (left to left, right to right). | As detailed below step length for FeetMe® was calculated.** Stride length is a parameter complementing step length and it was obtained with GAITRite® and FeetMe® devices | |
| Right | ||||
| Total* | ||||
*Total stride length = (Left stride + Right stride)/2; NA = Not applicable.
** Step length (cm) is measured along the line of progression from the heel center of the current footprint to the heel center of the previous footprint on the opposite foot.
