(a) Data acquisition set up, (b) intra-vaginal dynamometer, and (c) thigh dynamometer.
Fig 2.
Example of visual feedback during data acquisition: time series of force data from the thigh dynamometer (above graph) and the target level of 30% of hip isometric force; time series of force data from the vaginal dynamometer (bellow graph).
Fig 3.
Variables calculated from dynamometric assessment of PFM contraction: PFM maximum force (N), mean force (N), instant of maximum force (s), and PFM force loss integral (N.s).

Table 3.
Mean (standard deviation), confidence interval [95%] and effect size (confidence interval of effect size) of PFM maximum force (N), instant of maximum force (s), mean force (N.s) and force loss integral (N.s) from all conditions (hip adduction, abduction and isolated pelvic floor contraction) and the calculated gradients.
