Ultrasound imaging of core muscles activity in multiparous women with vaginal laxity: a cross-sectional study.

Vaginal laxity (VL) is a common condition among multiparous women, especially those who have delivered vaginally. Since pelvic floor muscles (PFMs) work synergistically with other core muscles, physical therapy protocols that aim to treat VL should train the PFMs in combination with other core muscles. To investigate the activity of core muscles in multiparous women with and without VL, and its relation to sexual function. An observational, cross-sectional study. The study included 100 multiparous women, who were divided into two groups according to their scores on the vaginal laxity questionnaire (VLQ). Women who scored between 1 and 3 on the VLQ were categorized as having VL (n = 48), while those who scored between 5 and 7 were placed in the control group (n = 52). The primary outcomes were PFM displacement, diaphragmatic excursion, transversus abdominis activation ratio, and lumbar multifidus thickness measured by ultrasound imaging. The secondary outcome was sexual functioning, evaluated using the Arabic female sexual function index (ArFSFI). The VL group had significantly lower PFM displacement (mean difference (MD) - 0.42; 95% confidence interval (CI) - 0.49 to - 0.33; p = 0.001), diaphragmatic excursion (MD - 2.75; 95% CI - 2.95 to - 2.55; p = 0.001), lumbar multifidus thickness (MD - 10.08; 95% CI - 14.32 to - 5.82; p = 0.02), and ArFSFI scores (MD - 9.2; 95% CI - 10.59 to - 7.81; p = 0.001) in comparison to the control group (p < 0.05). Nevertheless, the transversus abdominis activation ratio demonstrated no significant difference between the two groups (MD 0.06; 95% CI - 0.05 to 0.17; p = 0.33). Multiparous women with VL had significantly lower PFM displacement, diaphragmatic excursion, lumbar multifidus thickness, and sexual function index scores than women in the control group. The only exception was transversus abdominis activation, which did not differ significantly between the VL and control groups.

Effect of knack technique on vaginal laxity in multiparous women: A randomized controlled trial.

BACKGROUND: Vaginal laxity defined according to the International Urogynecological Association/International Continence society is excessive vaginal looseness; it is one of the most common symptoms of pelvic floor dysfunction, which refers to medical/functional disorders that can have a significant impact on a woman's sexual self-esteem and sexual life. AIM: This study aimed to determine the impact of the Knack Technique on Pelvic floor muscle (PFM) and sexual function in women with vaginal laxity. METHODS: Thirty females complaining of vaginal laxity were randomly chosen from the outpatient clinic at Deraya University. Their ages varied from 35 to 45 years, their body mass index was 25-30 kg/m2, and a number of parities ≤ three normal vaginal deliveries and at least two years from the last delivery complaining about vaginal laxity, water entrapment, and loss of friction during sexual intercourse. They were randomized into two equal groups at random (A, B). Group A (15 females) received (PSTES) and group B (15 females) received (PSTES) and Knack Technique. Both the groups received three sessions per week for 2 months. EVALUATION: The outcome measures were evaluated through pre- and post-interventions by using ultrasonography imaging to assess PFM function, Sexual Satisfaction Index, and Vaginal Laxity Questionnaires (VLQ) to assess sexual function. RESULTS: Analysis indicated a significant improvement in vaginal laxity in the two groups. Comparison between groups pre- and posttreatment showed that there was no statistically significant difference between the groups B and A in SSI and VLQ, while there were significant differences between the groups A and B in PFM force. CONCLUSION: Combining Parasacral transcutaneous electrical stimulation (PSTES) and Knack Technique is more effective than PSTES alone in reducing vaginal laxity as well as improving PFM and sexual function in women with vaginal laxity.
