This trial tests whether a non-drug electrical stimulation method (TENS-WAA) can reduce pain after thyroid surgery compared with a sham treatment.

Is this trial a fit for you?

Likely a good fit

Adults over 18 undergoing thyroid surgery with postoperative pain scores of 3 or higher.

Probably not a fit

Patients who have contraindications to electrical stimulation or do not experience pain after surgery may not benefit.

What this trial studies

Post-thyroidectomy pain is common and current pain control relies largely on medications that can cause side effects. This study evaluates transcutaneous electrical nerve stimulation based on wrist-ankle acupuncture theory (TENS-WAA) as an adjunct to standard multimodal analgesia. It is designed as a multicenter randomized setup to test effectiveness and safety of TENS-WAA in reducing pain scores after thyroidectomy. The objective is to provide evidence on whether this non-pharmacologic option can be integrated into ERAS-inspired postoperative care. The trial will monitor pain intensity, adverse events, and analgesic use to determine potential benefits and risks.

Why it matters

Potential benefit: If successful, patients could experience better pain control with fewer opioid-related side effects.

How similar studies have gone: Previous small, single-center studies suggest potential benefits, but high-quality multicenter randomized trials are needed.
