Background: More research is needed to determine the efficacy of transcutaneous electrical nerve stimulation (TENS) as a non-invasive pain control technique during office-based hysteroscopy.  
Objective: To assess the analgesic effects of transcuta-neous electrical nerve stimulation (TENS) in office hys-teroscopy procedures, as well as patient satisfaction with this intervention.
Patients and Methods: The study included 120 female volunteers who underwent office hysteroscopy and were divided into two groups: TENS group (60 individuals)   who got active TENS via a healthtronic alpha wave in-strument, and the Placebo group (60 participants) who re-ceived placebo TENS.
Results: The study declared that both TENS and placebo groups reported equal degrees of pain during hysterosco-py, with no significant changes in pain severity pain (p = 0.11) or satisfaction ratings. The VAS score linked posi-tively with age and parity, but adversely with height and the Likert verbal scale.
Conclusion: The TENS device does not significantly al-leviate the pain associated with office hysteroscopy.
