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

From: Expressing gait-line symmetry in able-bodied gait

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
  1. * 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)
