Introduction: Pelvic floor muscles in women play an important role in supporting the pelvic viscera, controlling voiding and defecation and helping in normal delivery. The pelvic floor muscles (PFM) may be exposed to alterations during different phases of a woman's life, such as pregnancy, the postpartum period, and physiological aging (menopause). Apart from incontinence, weak perineal muscles can give rise to many other pathologies including prolapse of pelvic organs. The evaluation of the PFM is important to provide prophylaxis and improve treatment of PFM dysfunctions. International Studies have supported the use of digital evaluation and pressure perineometry as simple, well-tolerated and minimally invasive methods that identify whether there is correct muscular recruitment and predicts PFM dysfunction. There is little literature available on PFM strength of females in Indian set up. This study is a genuine try to correlate digital evaluation with perineometry in measuring PFM strength in healthy young females. Objectives: The primary objective of the study is to correlate the per vaginal manual muscle testing (PVMMT) measured by digital examination to vaginal squeeze pressure (VSP) measured by perineometer in young continent females. The secondary objective is to see the difference in pelvic floor muscles strength between parous and nuliparous groups. Methodology: The females reporting to gynec OPD of V.S. General Hospital for routine checkup or for infertility were recruited. The inclusion criteria were: age range 20-40years, females without any pathology. Exclusion criteria: pregnant females, females with incontinence or other pathologies. Their pelvic floor muscles were assessed using PVMMT by digital examination and VSP by perineometer (PFX09122).The scores of PVMMT and perineometer were correlated. The difference of pelvic floor muscles strength in parous and nuliparous females was noted.
Results: There was statistically significant strong positive correlation between PVMMT and VSP. The spearmannís correlation coefficient r = 0.887 and p < 0.0001. Mann whitney u test was applied to see the difference in pelvic floor muscles strength of parous and nuliparous females. u= 58.00, p = 0.0367 for VSP and u = 50.50 and p = 0.0144 for PVMMT. This shows that there is a significant difference in pelvic floor muscle strength of parous and nuliparous females. Conclusion: The PVMMT and VSP are positively correlated with each other. This adds to the reliability of PVMMT in Indian set up. The parous women had less pelvic floor muscles strength than the nuliparous. This further supports that pregnancy affects the pelvic floor muscle strength.
