Can electrical pulses treat rheumatoid arthritis?

The answer

In 2025, researchers demonstrated that targeted electrical stimulation of the vagus nerve - a major nerve running from the brain through the neck to the abdomen - can significantly reduce inflammation in rheumatoid arthritis patients. The treatment, known as bioelectronic medicine, uses a small implanted device to send precise electrical pulses that activate the body's anti-inflammatory reflex, suppressing the overactive immune response that causes joint destruction in RA. Some patients who had failed to respond to conventional immunosuppressive drugs showed marked improvement with vagus nerve stimulation. The approach represents a paradigm shift from chemical drugs to electrical interventions, potentially offering fewer side effects and working through the body's own neural control of inflammation.
