We propose to extend the assessment of PNTML<\/jats:styled-content> to the measurement of the compound muscle action potential (CMAP<\/jats:styled-content>) of the EAS<\/jats:styled-content> to understand its progressive denervation.<\/jats:p><\/jats:sec>Method<\/jats:title>Ninety women with faecal incontinence were prospectively examined and compared with 36 asymptomatic women who acted as controls. PNTML<\/jats:styled-content> was performed bilaterally and the muscle response analysed for CMAP<\/jats:styled-content> to include amplitude, area and duration. Anorectal manometry was measured by a station\u2010pull technique using a water\u2010filled microballoon. spss<\/jats:sc> version 11.5 was used for statistical analysis.<\/jats:p><\/jats:sec>Results<\/jats:title>In asymptomatic women the CMAP<\/jats:styled-content> on the left side was greater in nulliparous (n\u00a0<\/jats:italic>=\u00a0<\/jats:italic>7) than parous (n\u00a0<\/jats:italic>=\u00a0<\/jats:italic>27, P\u00a0<\/jats:italic><\u00a0<\/jats:italic>0.05) individuals. There was a positive correlation with maximum squeeze pressure and area on the left side (P\u00a0<\/jats:italic><\u00a0<\/jats:italic>0.05, r\u00a0<\/jats:italic>=\u00a0<\/jats:italic>0.397). In women with faecal incontinence, CMAP<\/jats:styled-content> on the left side had a negative correlation with age (n\u00a0<\/jats:italic>=\u00a0<\/jats:italic>75, P\u00a0<\/jats:italic><\u00a0<\/jats:italic>0.05), there was no correlation with parity or anorectal manometry. Nulliparous asymptomatic women had a greater CMAP<\/jats:styled-content> (P\u00a0<\/jats:italic><\u00a0<\/jats:italic>0.05) on the left side than asymptomatic parous women and parous women with faecal incontinence. Right\u2010side measurements were not conclusive.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>Compound muscle action potential demonstrated progressive denervation with age in women with faecal incontinence but did not reliably identify early signs of denervation in asymptomatic women. The area on the left side related to muscle function in asymptomatic women but not in women with faecal incontinence. CMAP<\/jats:styled-content> can distinguish between parous women with faecal incontinence and nulliparous asymptomatic women but is not a useful test of function of the EAS<\/jats:styled-content>.<\/jats:bold><\/jats:p><\/jats:sec>","DOI":"10.1111\/codi.12315","type":"journal-article","created":{"date-parts":[[2013,6,12]],"date-time":"2013-06-12T07:06:38Z","timestamp":1371020798000},"page":"1289-1294","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Compound muscle action potential of the external anal sphincter"],"prefix":"10.1111","volume":"15","author":[{"given":"C.
