What this trial studies

This study evaluates the effectiveness of transcutaneous electrical nerve stimulation (TENS) units in managing pain during the insertion of intrauterine devices (IUDs). Eligible participants, aged 12 to 50, will be screened and consented before deciding whether to use the TENS unit during their IUD insertion appointment. Pain levels will be assessed at various stages of the procedure to determine the impact of TENS on pain management. The study aims to provide insights into patient preferences and pain experiences associated with IUD insertion.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 12 to 50 with a uterus who desire an IUD and can provide informed consent.

Not a fit: Patients with contraindications to IUD insertion or those with chronic pain conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce pain and improve the overall experience of IUD insertion for patients.

How similar studies have performed: While the use of TENS for pain management is established in other contexts, its application specifically for IUD insertion is relatively novel and untested.
