Abstract:

Faecal incontinence (FI) is one of most common anorectal dysfunctions. Contemporary diagnostic possibilities are very limited. Imaging studies enable precise assessment of external anal sphincter morphology and physiological studies can assess sphincter function. There is no efficient, yet easy to perform, method of sphincter innervation evaluation. 39 women and 10 men mean age 58,8 (21-81) were included to study group (FIG). Same number of healthy volunteers, mean age 45,3 (23-75) was included to control group (CG). Statistical analysis of amplitude (RMS) and frequency (MF) parameters was conducted. There was statistically significant (p<0,05) difference in RMS and MF between FIG and CG. In FIG there was a correlation between RMS and fecal incontinence FI (etiology). No differences were observed between idiopathic group and CG but they were significant between CG and neurogenic FI. Graphical trend analysis were carried out and revealed dependency of maximal squeeze pressure and RMS and MF both for relaxed and maximal contractions. Based on these results we concluded that Surface EMG can become a useful tool for diagnosis of FI especially for diagnosing neurogenic FI.
