“…It is known that this is not a practice in clinics and studios that work with the Pilates method. Studies show that approximately 30% of young women are not able to perform PFM contraction . Therefore, it would be important to assess the muscles of pregnant women before the Pilates intervention to ensure proper implementation of contraction during exercise.…”

“…The ability to produce a true maximal effort is particularly relevant in PFM. It is estimated that 30% of women are unable to contract these muscles even under verbal instruction 21 . Whenever the MVC of PFM is not an option, alternative methods of EMG normalization must be investigated.…”

Aims: To evaluate the reliability of different methods to normalize pelvic floor muscles (PFM) electromyography (EMG).Methods: Thirty nulliparous women (23.9 ± 3.2 years), free from PFM dysfunction, completed two test sessions 7 days apart. For EMG normalization, signals were acquired during four different tasks using a vaginal probe in situ:PFM maximal voluntary contraction (MVC) and three daily activities with increased intra-abdominal pressure (coughing, Valsalva maneuver, and abdominal contraction). The intraclass correlation coefficients (ICC), standard error of measurement (SEM), relative standard error of measurement (%SEM), and minimal detectable change (MDC) were calculated for each variable. Results: ICC values for test-retest reliability of normalization methods ranged from 0.61 to 0.95. The highest values were obtained for mean root mean square (RMS) of the abdominal contraction and peak RMS of PFM-MVC. Normalization using RMS of PFM-MVC showed the lowest values of SEM and MDC. Conclusions:The normalization of EMG data is considered a fundamental part of EMG investigations. These findings suggest that the normalization of PFM-EMG by either peak RMS of PFM-MVC or mean and peak RMS of abdominal contraction has excellent reliability and it can be applied in studies involving the evaluation of young women.

“…Our study also found a greater increase in EMG activity in the fast contractions, possibly due to the nature of the type II muscle fibers, which can generate a higher level of strength and power, but are easily fatigued [ 44 ]. Analysis of the results showed an increase of BASE values in all the examined groups after the 6-week training session and a decrease in the R values in all the examined subjects [ 45 ] showed that the EMG activity not only increased during the contractions, but also during the rest period at the beginning of the training session, although not significantly. It should be stressed that by evaluating the pelvic diaphragm in patients with pelvic organ prolapse in the resting state, it was preliminarily confirmed that the consistency of ultrasound and MRI was only moderate.…”

“…Pelvic floor muscle (PFM) exercises are a widely used and well-established form of stress incontinence treatment, with success rates between 21% and 84% [ 4 , 5 ]. The aim of the PFM training process (PMFT) is to teach and to bring back control over the peri-vaginal muscles, by learning to contract the pelvic-floor muscles [ 6 ]. PFM rehabilitation should begin with tonic activity, as this is often deficient [ 7 ].…”

BackgroundPelvic floor muscle exercises are a widely used and well-established form of stress incontinence treatment, with success rates varying from 21% to 84%, although with a better subjective than objective outcome.Material/Methods“Incontinence Impact Questionnaire” (IIQ), PFM EMG assessment was done at the beginning and after the 6-week training program.ResultsStatistically significant differences appeared in the BASE and R values. In the symptomatic group (with SUI symptoms), the value of BASE was 3.26 μV, and after training it was 3.95 μV. The R values before and after training were 4.55 μV and 4.25 μV. In the symptomatic group (without SUI symptoms), the value of BASE was 2.88 μV and 3.52 μV and R values were 7.16 μV and 3.92 μV. In the control group, BASE was 3.05 μV and 4.11 μV and R was 7.82 μV and 4.39 μV.ConclusionsThe results indicate that a 6-week training process influences PFM EMG activity in pregnant women. During Q, the value of PFM activity after a training session tended to increase in the symptomatic and control groups, but in the symptomatic group it remains practically unchanged. Our results show the probable process of decreasing control of PFM activity during long-lasting contractions in symptomatic and control women. The comparison of BASE before and after training averaged the values of R after five 10-s contractions and showed an increase in the Base and decrease in the R.
