In this work, we compared two fMRI paradigms to assess the volunteer pelvic floor muscles contraction.
Paradigms suited the block-design method and the action phases consisted in contraction of the pelvic floor muscles (continuously in "Continuous" paradigm and repeated in "pulsed" paradigm) and rest phases were complete relaxation.
Results showed that there was no significant difference in cluster size between "continuous" and "pulsed" paradigms. However, Z-max was significantly higher in the “pulsed” paradigm than in the “continuous” one (p <0.001). fMRI, with a pulsed paradigm, is a suitable technique to assess volunteer pelvic floor muscles contraction.
