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

Abstract

AbstractBackgroundVaginal 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.AimThis study aimed to determine the impact of the Knack Technique on Pelvic floor muscle (PFM) and sexual function in women with vaginal laxity.MethodsThirty 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.EvaluationThe 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.ResultsAnalysis 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.ConclusionCombining 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.
