How do daily work activities affect women's pelvic health?

Purpose
This study aims to understand how everyday occupational activities like standing or speaking over the span of a shift of work may affect a woman's pelvic floor muscles' ability to support pelvic organs.
Impact
Over their lifetime, 55% of women will experience urinary incontinence and 14% will experience symptomatic pelvic organ prolapse, typically associated with sneezing, jumping, running, coughing and shouting. It is thought that even job-related tasks like standing and talking could reduce pelvic floor support and lead to symptoms. By learning more about which daily work activities reduce muscular support for women’s pelvic regions, this research will help promote pelvic health for working women.
Background
The pelvic floor muscles in women are a group of muscles located between the tailbone and the pubic bone that act to support the pelvic organs (e.g. bladder, bowel, and uterus). Dysfunction of the pelvic floor muscles is often related to symptoms such as urinary incontinence, pelvic organ prolapse, and pelvic pain. Prior research suggests that urinary incontinence and overactive bladder may be more common for women in jobs that require a lot of standing and loud speaking—Manual labor, nursing, service/retail, and teaching/coaching.

"My previous work has shown that shouting causes strain in the pelvic floor, which inspired this study to examine the impacts of occupational voicing on pelvic support."

Study Details
The research team will recruit female volunteers to undergo ultrasound imaging of their pelvic floor immediately before and after a shift of work. Participants will also wear a vocal dosimeter as an adhesive patch on the front of their neck during work to capture voice use and total movements throughout the shift. Researchers will compare results between those that are active versus sedentary for work and those who have vocally demanding jobs or not.
