Determine the Foot Strike Pattern Using Inertial Sensors

Table 1

Data on the steps, strike index, and pitch angle for different speeds and landing strategies.

		Steps	Strike index (mean ± SD) (unit: radian)	Pitch angle (mean ± SD) (unit: radian)
Heel strike	7 km/hr	468	0.386 ± 0.092	0.384 ± 0.100
	10 km/hr	494	0.375 ± 0.145	0.388 ± 0.124
	13 km/hr	429	0.386 ± 0.092	0.449 ± 0.107
	Total	1391
Forefoot strike	7 km/hr	468	−0.040 ± 0.051	−0.080 ± 0.062
	10 km/hr	472	−0.033 ± 0.058	−0.068 ± 0.057
	13 km/hr	365	−0.012 ± 0.077	−0.020 ± 0.092
