Abstract: Objective To identify the relationship of pelvic floor muscle surface electromyography (sEMG) variables and the items ofthe International Bowel Function Basic Spinal Cord Injury (SCI) Data Set in patients with SCI. Methods 180 SCI patients were divided intoGroup A, B, C and D according to the International Standards for Neurological Classification of Spinal Cord Injury (American Spinal InjuryAssociation, ASIA). Testi was performed on 180 SCI subjects utilizing sEMG equipment, an inserted anal sensor electrode, and the Glazerprotocol. Questionnaire of the items in the International Bowel Function Basic SCI Data Set were conducted. Results The values of pelvicmuscle sEMG variables were significantly correlated with awareness of the need to defecate, major defecation method, average time requiredfor defecation, frequency of fecal incontinence, need to wear pad or plug (P<0.05), as well as the impairment scale of ASIA (P<0.01).Conclusion Glazer pelvic floor muscle sEMG protocol and questionnaire of the International Bowel Function Basic SCI Data Set are usefulcomplementary methods for the choice of hydrotherapy types in patients with SCI.
