At the heel, thresholds obtained with the 10 mm probe were
lower than thresholds obtained with the 6 mm probe (p = 0.003).
There was no significant difference between thresholds obtained
with 6 mm and 3 mm probes (p = 0.136), although 9 of 12 the thresholds
obtained with 6 mm probe were higher than those with the
3 mm probe. Vibrotactile thresholds obtained with the 3 mm probe
were lower than thresholds obtained with 1 mm probe (p = 0.041).
At the fingertip, thresholds obtained with the 10 mm probe
were lower than thresholds with the 6 mm probe, thresholds with
the 6 mm probe were lower than those obtained with the 3 mm
probe, and thresholds with the 3 mm probe were lower than those
obtained with the 1 mm probe (Table 2).
