Introduction Men with chronic pelvic pain syndrome (CPPS) experience pelvic pain that may be related to muscle dysfunction. Since few studies have attempted to document pelvic floor muscle function in men with CPPS, we performed a comparative study of the pelvic floor muscles in men with CPPS and men without pain.

Methods Eleven men with CPPS and 32 controls underwent a standardized physical therapy evaluation. The evaluation was done in an unblinded manner by a registered physical therapist (DH) specializing in pelvic floor dysfunction.

Results Pelvic floor tone increase was found in 8/11 (73%) patients and 3/32 (9%) controls (p=.0001, chi square). Pelvic floor spasms were detected in 4/11 (36%) patients and 0/32 controls (p=.0027 chi square). Asymmetry of pelvic floor contractions was found in 2/11(18%) patients and 0/32 controls (p=.06 chi square). Increased pain with palpation of pelvic muscles was found in 6/11(55%) patients and 1/32 (3%) controls (p=.0005). Pelvic floor quick contraction was found to be strong in 2/11(18%) patients and 10/32 (31%) controls (p=.02). Abdominal tension with palpation was found in 8/11(73%) patients and 7/32 (22%) controls (P=.004). Abdominal pain with palpation was found in 4/11(36%) patients and 7/32(22%) controls (p=.01).

Conclusions Men with CPPS have more abnormal pelvic floor and abdominal muscular pathologic findings as compared with a group of men without pain.
