Pelvic floor muscle examination in female chronic pelvic pain.
The Journal of reproductive medicine, 2011•europepmc.org
Objective To determine if women with self-reported chronic pelvic pain (CPP) were more
likely to have positive findings on two vaginal pelvic floor muscle (PFM) tests compared to
women without CPP when the examiner was blinded to pain status. Study design This was a
prospective, cross-sectional study. Blinded examiners performed two vaginal pelvic floor
tests (tenderness and strength) on 48 participants: 19 with self-reported CPP and 29 who
were pain-free. Relative frequency of positive findings between groups and the total number …

Objective
To determine if women with self-reported chronic pelvic pain (CPP) were more likely to have positive findings on two vaginal pelvic floor muscle (PFM) tests compared to women without CPP when the examiner was blinded to pain status.
Study design
This was a prospective, cross-sectional study. Blinded examiners performed two vaginal pelvic floor tests (tenderness and strength) on 48 participants: 19 with self-reported CPP and 29 who were pain-free. Relative frequency of positive findings between groups and the total number of positive physical examination findings were calculated.
Results
Women with self-reported CPP were more likely to have PFM tenderness (63.2% with physician [MD] examiners [board certified in physical medicine and rehabilitation] and 73.7% with physical therapist [PT] examiners) as compared to pain-free participants (Fisher's exact test [FET]), 48 p< 0.001 with MD, p< 0.001 with PT). PFM weakness was not more likely in women with CPP (31.6% with MD, 42.1% with PT) as compared with pain-free participants (48.3% with MD, 17.2% with PT)(FET, 48 p= 0.37 with MD, p= 0.096 with PT).
Conclusion
PFM tenderness is found more frequently in women with self-reported CPP than in pain-free women. PFM strength did not differentiate CPP from pain-free participants. Improved standardization of the PFM examination across disciplines may be helpful in distinguishing subgroups and treating women with CPP.
