Aim:  To evaluate pelvic floor muscle (PFM) function and its association with urinary symptoms in the third trimester of pregnancy. Material and Methods:  A cross-sectional study was conducted among 91 nulliparous women at 30-34 weeks of pregnancy. PFM was evaluated by surface electromyography (sEMG) and manual muscle testing, while urinary symptoms were identified by interview. Chi-square and Fisher's exact tests were used to analyze proportions and Mann-Whitney test was used to analyze differences in means. Results:  Average sEMG values were 4.8 µV for basic tonus (BT), 19.2 µV for maximum voluntary contraction (MVC), and 12.9 µV for average sustained contraction (ASC), and 48.4% presented muscle strength grade 3. Nocturia was reported by 80.2%, followed by increased daytime frequency (59.3%), stress urinary incontinence (50.5%), and urge urinary incontinence (25.3%). No association was found between urinary symptoms and MVC or ASC or PFM manual tested strength. Conclusion:  No association was observed between PFM function and urinary incontinence, except decreased BT among late third trimester pregnant women with irritative bladder symptoms.
