Chronic pelvic pain (CPP) is defined as non-cyclic pelvic pain lasting at least 6 months. Approximately 3-15% of women are affected by CPP. Care of patients with CPP contributes to considerable healthcare costs, accounting for 880 million dollars annually in outpatient visits alone. Although CPP may be multifactorial, many women have a contribution from increased pelvic floor tone. CPP due to increased pelvic floor tone is usually referred to as levator spasm or high tone pelvic floor dysfunction. Levator tenderness and increased pelvic tone may be identified on physical exam. However, physical exam is somewhat subjective and may vary based on the clinician performing the exam. There are currently no validated, objective measures to judge resting pelvic tone, which 1) limits objective assessment in research studies and 2) limits our ability to assess response to new treatment modalities.
