<p><strong>Methods: </strong>A cross-sectional study, 50 nulliparous were recruited. Modified oxford scale (MOS) was assessed by one author (OW) and highest maximum squeeze value was recorded. The vaginal pressure during maximum squeeze with PFX2<sup>®</sup> perineometer was recorded by one trained nurse. The midsagittal view of anteroposterior (AP) hiatal dimension using 2D transperineal ultrasound (TPUS) was done by the other author (PL) to measure the difference between the AP hiatal dimension in the resting stage compared to maximum squeeze.</p>
<p><strong>Result: </strong>The mean MOS <u>+</u> SD was 4.4 <u>+</u> 0.7. The mean <u>+</u> SD PFX2<sup>®</sup> perineometer was 10.4 <u>+</u> 1.8 cmH2O. The mean <u>+</u> SD difference of AP dimension using TPUS was 1.1 <u>+</u> 0.6 cm (22.8 <u>+</u> 10%). PFX2<sup>®</sup> perineometer was poorly correlated with the different AP dimension using TPUS (r = 0.19, p-value = 0.18) and weakly correlated with the percent of difference AP dimension using TPUS (r = 0.21, p-value = 0.15). MOS was moderately correlated with the difference and percent of difference AP dimension using TPUS (r = 0.35, p-value<0.05 and r= 0.34, p-value<0.05 respectively). MOS was strongly correlated to PFX2<sup>®</sup> perineometer (r= 0.73, p-value < 0.05).</p>
<p><strong>Conclusion: </strong>In healthy nulliparous women, PFX2<sup>®</sup> perineometer and MOS could be used to assess the strength of the pelvic floor muscles, but two-dimension TPUS could not be used to assess it. Because the difference hiatal dimension is small due to nulliparous characterization.</p>}, number={3}, journal={Asian Medical Journal and Alternative Medicine}, author={Iaocharoen, Puckjira and Lekskulchai, Orawan and Chiengthong, Keerati and Bunyavejchevin, Suvit and Tanprasertkul, Chamnan and Somprasit, Charintip}, year={2023}, month={Dec.}, pages={72–80} }
