Abstract Backgorund Patients suspected of having swallowing disorders could highly benefit from simple diagnostic screening before being referred to specialist evaluations. We introduce surface electromyography sEMG to carry out rapid assessment of such patients and propose suggestions for standardizing sEMGs in order to identify abnormal deglutition. Methods Specifics steps for establishing standards for applying the technique for screening purposes e.g. evaluation of specific muscles the requirements for diagnostic sEMG equipment the sEMG technique itself and defining the tests suitable for assessing deglutition e.g. saliva normal and excessive swallows and uninterrupted drinking of water are presented in detail. A previously described normative database for single swallowing and drinking and standard approach to analysis was compared to data on the duration and electric activity of muscles involved in deglutition and with sEMG recordings in order to estimate stages of a swallow. .
