Objectives

Narrative objectives1

In this study, we focused on the pelvic floor muscle innervating the internal pudendal artery, which runs in the vicinity of the uterine artery, and aimed to verify the effect of voluntary contraction of the pelvic floor muscle on the blood flow of the uterine artery.

Interventions/Control_1

Measurement of basal body temperature will begin at least one month prior to the data measurement date to predict the menstrual, proliferative, and secretory phases. In parallel, voluntary contraction exercises of the pelvic floor muscle will be performed. To confirm the voluntary contraction of the pelvic floor muscle , the lower end of the bladder base will be drawn by transabdominal ultrasonography, and the contraction will be confirmed by raising the bladder base, and the amount of raising at the time of maximum voluntary contraction will be measured. Time Averaged Mean Velocity,Time Averaged Maximum Velocity, Pulsatility Index, and Resistance Index of the pelvic floor muscle before and after voluntary contraction will be measured by transvaginal ultrasonography during the menstrual - proliferative phase and the secretory phase of each study subject.

Results

There were no main effects or interactions for time-averaged maximum velocity. There was a main effect of contraction of the pelvic floor muscles before and after contraction on time-averaged mean velocity, which increased significantly after contraction compared to before (p=0.023).

Baseline Characteristics

The basic attributes were age 31.1 years, and age at menarche 12.4 years.The menstrual cycle and duration of menstruation were all within normal limits.

Participant flow

Thirteen participants were included in the study, and 8 were eligible for analysis, excluding 5 who were excluded. The exclusions included 1 participant who discontinued the experiment due to irregular bleeding, 1 participant who withdrew consent, 1 participant who had anovulatory cycles, and 2 participants with missing data.

Adverse events

None

Outcome measures

Two-way analysis of variance was used to test for differences in time-averaged maximum velocity, time-averaged mean velocity, Pulsatility Index, and Resistance Index during menstruation and before and after contraction of the pelvic floor muscle group.No main effects were found for time-averaged maximum flow velocity, Pulsatility Index, or Resistance Index. There was a main effect of contraction of the pelvic floor muscle group before and after the contraction of the pelvic floor muscles on the time-averaged mean velocity.

Pearson's correlation coefficient was used to correlate the change in time-averaged maximum velocity and time-averaged mean velocity before and after pelvic floor muscles contraction with the rate of pelvic floor elevation. No relationship was found between the change in time-averaged maximum velocity or time-averaged mean velocity and the rate of pelvic floor elevation.
