Sixty patients with spinal cord stimulators implanted for intractable pain lasting up to 50 years were followed for up to nine years. Forty seven per cent derived significant benefit, 23% modest benefit, 20% experienced no effect and 6.7% were made worse. Two were made worse after initial benefit. Complications, indications and factors relevant to the mode of action are discussed.
