Abstract

Abstract:

Objective To investigate the characteristics of pelvic floor structure and electrophysiology in female patients with stroke.

Methods From June to December, 2020, 21 female inpatients with stroke in Zhongda Hospital, Southeast University (stroke group) were divided into urinary incontinence (UI) group (n = 6) and non-urinary incontinence (NUI) group (n = 15), and other 20 healthy subjects were as control group. They were observed with pelvic floor ultrasonography and pelvic floor surface electromyogram.

Results Average electromyography, integral electromyography, root mean square, mean power frequency and median frequency decreased in UI and NUI groups compared with those of the control group (P < 0.05), but there was no significant difference between UI group and NUI group (P > 0.05). Bladder neck position, bladder neck angle, bladder neck mobility, urethral rotation angle; and anteroposterior diameter, left-right diameter and area of levator ani muscle hiatus after Valsalva's action were all not different among three groups (F < 2.484, P > 0.05).

Conclusion The activities of pelvic floor muscles decrease in female patients with stroke, without obvious changes of pelvic floor supporting structures, whatever UI.

Key words: stroke, female, pelvic floor
