Table 2 Mean, SD, 95% CI, and range of the test parameters

From: Classification of the height and flexibility of the medial longitudinal arch of the foot

Maximum values n = 254
Test Mean SD 95% CI Range
NH (cm) 4.6 0.9 4.4 to 4.7 2.0 to 7.2
FL (cm) -1.9 0.7 -2.0 to -1.8 -4.0 to 2.2
LAA (°) 142 10.4 141 to 143 114 to 172
Range of motion values n = 254
Test Mean SD 95% CI Range
ND (cm) 1.2 0.6 1.1 to 1.3 -0.3 to 3.2
FL (cm) 0.4 0.5 0.3 to 0.5 -3.8 to 2.3
LAA (°) 6 7 5 to 7 -15 to 26
  1. Mean, standard deviation (SD), 95% confidence intervals (95% CI), and range between minimum and maximum values for navicular height (NH), navicular drop (ND), Feiss line (FL) and longitudinal arch angle (LAA). Maximum values represent the foot in its weight-bearing position. Range of motion represents the difference between subtalar neutral position and subtalar resting position with both feet in a weight bearing condition
