Influence of visual feedback on pelvic floor muscle strength
Abstract
OBJECTIVE: The objective of this study is to evaluate the visual feedback influence on pelvic floor muscle contraction.
STUDY DESIGN: Seventeen nulliparous, urinary-continent women participated in this study. Pelvic floor muscle strength with and without the use of visual feedback was measured with a dynamometric speculum in two directions (anteroposterior and left-right). To compare the mean strength values with and without the use of visual feedback, the t test was applied.
RESULTS: There was no significant difference between the pelvic floor muscle anteroposterior strength values with and without the use of visual feedback (p=0.30), and no significant difference for the left-right strength (p=0.37).
CONCLUSION: There was no difference between the pelvic floor muscle strength values with and without the use of visual feedback.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
