Table 3 Mean values (SD) for the medial and lateral rearfoot (N=30)

From: The effect of different depths of medial heel skive on plantar pressures

  1. * Mean difference significant at the 0.05 level (Bonferroni adjusted) compared to the unmodified orthosis.
  2. # Mean difference significant at the 0.05 level (Bonferroni adjusted) compared to the orthosis with a 2 mm heel skive.
  3. Mean difference significant at the 0.05 level (Bonferroni adjusted) compared to the orthosis with a 4 mm heel skive.
