Clinical Trial Summary

The purpose of this study is to see whether transcutaneous electrical nerve stimulation (or TENS) reduces pain during an endometrial biopsy. A TENS unit is an over-the-counter, FDA approved device that sends low-level electrical impulses through the skin to reduce the amount of discomfort experienced during procedures. A TENS unit is very low-risk and used in a lot of ways, including for chronic pain, after surgery, and during labor. Since there is no standard way of managing discomfort during an endometrial biopsy, the investigators think that TENS might be helpful. Participating in the study may require some additional time in clinic to answer research-related questions. Subjects will be asked to answer demographic questions (which will be combined anonymously) before and after the procedure, as well as rate subject's pain at different time points during the procedure. The biggest benefit in participating is that subject's discomfort might be lower during and after the procedure. Subjects may not benefit from participating in this study. There is a small risk of a skin reaction from wearing the TENS pads.

Outcome

Type Measure Description Time frame Safety issue
Primary Pain after Endometrial Biopsy, as measured by Visual Analogue Scale (VAS) Scores are measured on a 100 mm VAS. The VAS ranges from 0 to 100 mm with the lower score indicating less pain and the higher score indicating greater pain Immediately after endometrial biopsy
Secondary Number of participants who find the intervention acceptable based on survey response A 0 to 100 mm scale similar to VAS to assess acceptability of TENS intervention End of procedure
Secondary Number of participants who find the intervention tolerable based on survey response A 0 to 100 mm scale similar to VAS to assess tolerability of TENS intervention End of procedure
Secondary Change in Pain, as measured by Visual Analogue Scale (VAS) across different time intervals Scores are measured on a 100 mm VAS. The VAS ranges from 0 to 100 mm with the lower score indicating less pain and the higher score indicating greater pain Speculum placement, tenaculum placement, 5 minutes after biopsy, and 15 minutes after biopsy
Secondary Provider satisfaction with the procedure A 0 to 100 mm scale similar to VAS to assess provider satisfaction End of procedure
