Table 6.
Mean and one standard deviation (SD) of calculated delays in studies that evaluated their gait phase detection (GPD) algorithm vs. force-sensing resistor GPD (GPD-FSR). Values are in milliseconds and negative values correspond to delays relative to GPD-FSR. Delays are reported for heel strike (HS) and toe-off (TO).
