Analysis of the characteristics and clinical significance of pelvic floor electrophysiology and imaging changes in female patients with MFPP

Abstract

ObjectiveChronic Pelvic Pain (CPP) is a very common disease. Studies have found that some female patients with CPP have a myofascial trigger point for pain, which has classified as myofascial pelvic pain (MFPP). This study intends to compare the changes of pelvic floor electrophysiology and imaging between female patients with MFPP and normal women by measuring pelvic floor muscle potential, tension and two-dimensional and three-dimensional ultrasound, and then to explore the characteristics and significance of the changes. MethodsA total of 49 MFPP patients were randomly selected as the study group and 41 healthy women were randomly selected as the control group. Vaginal muscle potential was detected by pelvic floor muscle potential tester. The electronic tensioner was used to measure the muscle tension and the pelvic floor muscle contraction force of 5o and 10o, respectively. The parameters of the two groups were detected by transperineal 2D ultrasound and transvaginal 3D ultrasound respectively. Results1. The resting muscle potential and maximum muscle potential of the study group were higher than those of the control group. 2. The static tension, dynamic tension and contractile force of pelvic floor muscle in the study group were higher than those in the control group when the tensioner was opened for 5o. 3. In resting state, BND, BSD and anterior-to-posterior diameter of genital tract hiatus in the study group were smaller than those in the control group. The anal Angle in Valsalva state was greater in study group than in control group. 4. At rest, the hiatus area, anterior-posterior diameter, transverse diameter and defect score of the levator anal muscle in the study group were smaller than those in the control group. ConclusionMFPP presents a state of continuous spasm and loss of coordination of pelvic floor muscle fascia.
