Table 1 Definition of outcome measures, as displayed in Figure 1
Outcome measure | Description |
|---|---|
Fz1 | Local maximum in the vertical GRF data, normalized to body weight (BW). |
Fz2 | Maximum value in the vertical GRF data, normalized to BW. |
LR | The steepest part of the vertical GRF curve, from stance to impact peak. Expressed in BW/s. |
ALR | Average loading rate, the slope of the line from 20% to 80% of Fz1. Expressed in BW/s. |
tFz1 | Time from heelstrike to Fz1 in ms. |
tFz2 | Time from heelstrike to Fz2 in ms. |
CT | Contact time, from heelstrike to toe-off in ms. |
