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

A small device that delivers 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 reported that the approach could help some people whose blood pressure remains high despite taking medication.

The device works by stimulating nerves in the ear with gentle electrical impulses. The findings suggest a possible role for this technique in managing blood pressure that is difficult to control with existing treatment.

The results do not establish the device as a cure or a replacement for prescribed medication. The information provided about the study does not specify how much patients’ blood pressure fell or how long any improvement lasted.

Further evidence would be needed to determine how effective the approach is, which patients might benefit and whether its effects can be sustained.
