INTRODUCTION: Recent studies demonstrated that a significant correlation exists between tissue lesions which occur during natural childbirth, either spontaneous or induced (episiotomy), and subsequent appearance of fecal incontinence in women. Knowledge of the location of the innervation zones and of the anatomy of the anal sphincter will allow avoiding such zones during episiotomy with expected significant reduction of the consequences of this surgery. After demonstration of the feasibility of EAS investigation through EMG rectal probes designed for research purposes, it became evident that arrays with more than 16 contacts were needed to study individual motor units, and disposable low-cost probes would be required by the market. AIM: The aim of this work was to develop a low cost disposable rectal probe which allowed the detection of high density electromyography from the external anal sphincter. METHODS: The device developed for this purpose is constituted of: 1) Electrical circuits with one silver electrode array printed on flexible plastic film, 2) A plastic support with a conic portion in the central part of the body. The plastic flexible circuits are wrapped and glued around the plastic support creating a cylindrical probe with one or more arrays of electrodes. RESULTS: The probe was tested on seven patients allowing the identification of single motor units by means of a surface EMG decomposition algorithm (Holobar and Zazula. 2004). The analysis of EMG signals recorded with this probe allowed the evaluation of the innervation zone distribution and the computation of EMG amplitude maps of the sphincter muscles. CONCLUSION: Low-cost, disposable e minimally invasive EMG probes will enable preventive screening on every pregnancy to minimize the risk of episiotomy.
