Effect of Transcutaneous Tibial Nerve Stimulation in Multiparous Egyptian Women with Vaginal Laxity: A Randomized Controlled Trial

Vaginal laxity (VL) is a common symptom of pelvic floor disorder, an underreported condition, and has a substantial impact on women's sex lives and relationships. The study aimed to determine the effect of transcutaneous tibial nerve stimulation (TTNS) on women with VL. Fifty women with vaginal laxity were chosen from an outpatient clinic in Egypt. They were randomly split into two equal categories (A and B). Group A (n = 25) received pelvic floor exercises (PFE), while Group B (n = 25) received TTNS and PFE. Every week, both groups performed three sessions for three months. The outcomes were evaluated both before and following treatment using ultrasound imaging to assess pelvic floor muscle (PFM) function and the Female Sexual Function Index to measure sexual function. Vaginal Laxity Questionnaire (VLQ) were used to examine vaginal looseness. The analysis demonstrated a significant improvement in vaginal laxity in both groups. Post-treatment comparisons revealed a statistically significant difference in VLQ scores and PFM strength between Groups B and A. These findings indicate that TTNS is notably more effective in improving PFM activity and VLQ scores in women with vaginal laxity.
