Table 5 Effect of PND on EMG and PNTML

From: Pudendal nerve decompression in perineology : a case series

  Anal Richness (range 1 to 6) BC Richness (range 1 to 6) Anal PNTML (msec) Perineal PNTML (msec)
All subjects 74 74 74 74
Follow up less than 12 months or lost 39 39 39 39
Analysed cases(left and right) 70 61 70 51
Mean Before 2,70 2,23 3,38 5,63
Mean After 3,11 2,44 2,63 5,21
t-test p-value(one-tail) 0,00007 0,06989 0,00004 0,00816
  1. Left and right values for each level (anal and perineal) were included in the same group. P-values at the bottom line correspond to one-tailed significance tests of the mean differences "before" versus "after".
