Comparing pain perception with fast and slow tenaculum application techniques

Official title: A Randomized Controlled Trial of Pain Perception With Fast and Slow Tenaculum Application to the Uterine Cervix

Run by Women and Infants Hospital of Rhode Island · NCT05458037 · Data updated 2026-11-12

This study is testing whether placing a tenaculum slowly on the cervix causes less pain than doing it quickly for women undergoing this procedure.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 18 to 49 who are planning for IUD insertion or endometrial biopsy and can provide informed consent.

Probably not a fit

Patients who have taken analgesics, anxiolytics, or certain recreational drugs within specified time frames may not benefit from this study.

What this trial studies

This project is a randomized controlled trial measuring pain perception during two different techniques of tenaculum placement on the uterine cervix. The study will utilize a Visual Analog Scale (VAS) to assess pain levels from 0 to 100 mm for both fast and slow application methods. The primary goal is to determine if the slow technique results in less pain perception compared to the fast technique. A total of 150 subjects will be recruited, with 75 in each group, to ensure adequate power for detecting significant differences in pain levels.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management techniques during gynecological procedures.

How similar studies have gone: Previous studies have explored pain perception in similar contexts, but this specific comparison of tenaculum application techniques is novel.
