Postural Sensorimotor Control on Anorectal Pressures and Pelvic Floor Muscle Tone and Strength: Effects of a Single 5P LOGSURF Session. A Cross-Sectional Preliminary Study.

Pelvic floor dysfunction (PFD) is a functional condition present most frequently in women. Despite pelvic floor muscle training being considered by the International Continence Society (ICS) as the first-line treatment in uncomplicated urinary incontinence, other more comprehensive postural methods as 5P LOGSURF have emerged. This preliminary cross-sectional study explores the effects of a single 5P LOGSURF session on pelvic floor muscle (PFM) tone and strength (MVC), resting anal tone, intrarectal pressure, and deep abdominal muscles activation. Thirty women were included (11 without PFD and 19 with PFD). Primary outcome measures were PFM tone, PFM MVC and resting anal tone and secondary measures outcomes were intrarectal pressure and deep abdominal activation. All outcome measures were collected before, throughout and after a single 30' 5P LOGSURF session. The findings from this study suggest that PFM tone (PFD group: = 0.09, = 0.72; non-PFD group: = 0.003, = 0.49) and PFM MVC (PFD group: = 0.016; non-PFD group: = 0.005) decreased in both groups after a single 5P LOGSURF session, with a medium effect size for women with PFD. Contrarily, deep abdominal muscle MVC increased (PFD group: < 0.001; non-PFD group: = 0.03). Intrarectal pressure and resting anal tone decreased in both groups throughout the session. These results suggest that 5P LOGSURF method may be interesting if is performed by women with mild symptoms of PFD or healthy women to achieve a decrease in PFM tone in women who manifested pain to intracavitary techniques or practices. Further research with higher sample sizes and long-term are necessary for generalizing.
