Table 2 Quantitative description of AsCs curves with points outside ± 1.96 SD and ± 3 SD ranges for healthy able-bodied subjects.

Number of points outside the range: AsC ± 1.96 SD	Number of subjects	Percentage of subjects
0	45	58
1–10	20 (17)*	26 (22)*
11–20	4	5
21–30	4	5
over 30	4	5
Number of points outside the range: AsC ± 3 SD	Number of subjects	Percentage of subjects
0	74	96
1–10	3	4
11–20	0	0
21–30	0	0
over 30	0	0

* numbers in brackets denote number of subjects for which the points outside the AsC ± 1.96 SD range were observed only in the area from 0–5% heel-toe sensors distance (heel strike) or over 80% (toe off)
