Table 4 Mean values (SD) for the medial and lateral midfoot (N=30)

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

     Medial midfoot    
  Peak pressure (kPa) Maximum force (%BW) Contact area (cm2)
Condition Mean (SD) % change p-value Mean (SD) % change p-value Mean (SD) % change p-value
Orthosis with no heel skive 81.9 (27.2) n/a n/a 8.6 (3.8) n/a n/a 14.5 (3.6) n/a n/a
Orthosis with 2 mm heel skive 83.7 (23.1) +2% 1.000 8.9 (4.4) +4% 1.000 13.9 (4.3) -4% 1.000
Orthosis with 4 mm heel skive 79.5 (24.1) -3% 1.000 8.5 (4.3) -0.4% 1.000 14.3 (3.8) -1% 1.000
Orthosis with 6 mm heel skive 79.0 (25.7) -4% 1.000 8.3 (3.9) -3% 1.000 14.3 (3.4) -1% 1.000
     Lateral midfoot    
  Peak pressure (kPa) Maximum force (%BW) Contact area (cm 2 )
Condition Mean (SD) % change p -value Mean (SD) % change p -value Mean (SD) % change p -value

Orthosis with 2 mm heel skive 92.3 (26.9) +1% 1.000 12.5 (4.6) +5% 1.000 16.1 (2.7) +2% 1.000
Orthosis with 4 mm heel skive 87.2 (23.8) -4% 1.000 11.9 (4.3) 0 1.000 16.2 (2.7) +2% 1.000

  1. *Mean difference significant at the 0.05 level (Bonferroni adjusted) compared to the unmodified orthosis.
