Among the women drawn from the community who participated in the study, almost none had urinary incontinence all the time but about half had it at some times.
The trial randomised 50 women to receive an education lecture weekly for 4 weeks (the experimental group) and 49 women to a control group that received no intervention. At the end of the 4-week period, the educational intervention hasn't made much difference to the ability to contract the pelvic floor muscles, or the severity of urinary incontinence. Most women reported no sexual activity, so the researchers couldn't really assess that.
However, the women's knowledge about the pelvic floor improved significantly. Women in the experimental group were about 1.5 times more likely to locate the pelvic floor muscles correctly, about twice as likely to know the functions of the pelvic floor muscles, about 3 times more likely to know the range of dysfunctions related to the pelvic floor muscles, and nearly 4 times more like to know the available treatment options.
So, even though many of the women may not've had much problem with their pelvic floor muscles during the study, they were better prepared to recognise any future dysfunction and seek appropriate help.
