Transcutaneous electrical nerve stimulation (TENS) is a form of electroanalgesia used for neuropathic pain disorders. Refractory chronic cough, or “neuropathic cough,” may be physiologically similar to other neuropathic pain conditions.

This study explored the tolerability and feasibility of using TENS as a treatment for neuropathic cough.

Laryngeal TENS was well tolerated by all subjects. Adverse effects included brief neck discomfort when increasing TENS intensity and an event of mild post-treatment hoarseness.

The self-reported scores trended toward a reduction in symptom severity during and after treatment. Controlled trials using this method would elucidate the use of TENS for treatment of patients suffering from chronic cough.
