Ear Nerve Stimulation Shows Promise for Hard-to-Control Blood Pressure

A small device that sends mild electrical pulses to nerves in the ear has shown encouraging results in some patients with high blood pressure, according to British researchers.

Following a clinical study, the researchers found that stimulating ear nerves may help patients whose blood pressure remains elevated despite taking medication.

The approach uses gentle electrical stimulation rather than an additional drug. Its potential lies in helping people whose existing treatment has not brought their blood pressure under control.

The findings suggest a possible new avenue for treatment, but do not establish ear nerve stimulation as a cure or a replacement for prescribed medication. The reported benefits were seen in some patients, not necessarily everyone with high blood pressure.

The available summary did not specify the study’s size, the extent of the blood pressure reduction or how long the effects lasted. Those details would be important in assessing the device’s potential role in care.
