Szukana fraza: [Abstrakt = "in rest and during maximal contraction of the EAS. The analysis was performed within the identified groups \(RR – all operated, AR – Anterior Rectal Resection, LAR – Low Anterior Rectal Resection, RTH – Radiotherapy\) and also between AR and LAR groups. Significant change of sEMG parameters was observed. The RMS reduction and as well as MNF increase were observed after the surgery in RR group. In subsequent periods of evaluation \(6 and 12 months\) increased values of sEMG parameters were revealed which correlate with manometric measures. There were statistically significant differences concerning sEMG parameters and manometry between LAR and AR groups. Electromyographic recordings correlate both with results of anorectal manometry and functional dynamic tests, but also with the intensification of faecal incontinence measured with FISI scale. Significant influence of radiotherapy on motor action of anal sphincters was revealed. The obtained results allow to evaluate sEMG as a reliable method of evaluation of functional condition of the sphincters complex both in relation to genesis of their dysfunction \(neurogenic\) and in prognostic context – that is regression of LARS symptoms in specific time."]
