Nerve stimulation to be trialled for refractory RA
Pilot trial of a device the size of a coffee bean shows it is well tolerated

Tiny devices implanted on the vagus nerve and used for a few minutes a day might be able to reduce the signs and symptoms of rheumatoid arthritis, say the authors of a pilot study.
Researchers have previously used vagus-nerve stimulators, about the size of a coffee bean, as anti-seizure devices.
