The aim of the study was to compare electrophysiological phenomena occurring in gracilis muscle, transposed into pelvic floor during graciloplasty procedure, subjected continuous electrical stimulation by means implanted stimulator, or regular an external device, as well long-term functional results procedure.A total 27 patients were included analysis. group consisted 7 after dynamic graciloplasty, 11 followed transrectal stimulation, 4 with transcutaneous and 5 without any stimulation. All had a surface electromyographic examination muscle performed, signal for each patient compared acquisited from non-transposed same patient. In addition, subject underwent clinical operation assessment, anorectal manometry examination.In electromiographic examination, mean frequency motor units action potentials thigh 64 Hz, transposition period 62 Hz. There no statistically significant difference before treatment analyzed groups, between groups different methods (p> 0.05). We found correlation outcome average amplitude EMG basal pressure anal canal manometric examination. correlations remaining parameters.Despite postoperative including expensive implantable stimulators, there activity left situ. signoficant advantage procedure over transanal
