However, only limited data are available on the diagnostic usefulness of these parameters. In the present study, we compared the sensitivities of MUP parameters in revealing \u201cneuropathic\u201d changes in the external anal sphincter (EAS) muscles in 56 patients examined 5\u2013240 months after damage to the cauda equina or conus medullaris. Using multi\u2010MUP analysis, 20 MUPs were obtained from patients' EAS muscles. Their MUP parameters were compared with normative data from 64 controls. The diagnostic sensitivities of mean values\/\u201coutliers\u201d of MUP parameters for detecting neuropathic EAS muscles were calculated (area 25%\/30%; number of turns 18%\/29%; size index 13%\/24%; thickness 18%\/18%; amplitude 17%\/17%; spike duration 20%\/9%; duration 15%\/12%; number of phases 15%\/11%; and their combination 51%\/52%). Altogether, the cumulative sensitivity of multi\u2010MUP analysis using both mean values and \u201coutliers\u201d was 62%. The combination of MUP parameters improves the diagnostic yield of MUP analysis, but the influence on specificity remains unknown. \u00a9 2001 John Wiley &amp; Sons, Inc.
