Dorsal column stimulation for control of pain: a three-year follow-up.
The long-term (three-year) effect of dorsal column electrical stimulation for chronic pain in a group of 30 patients was generally decreased effectiveness with time, and increased stimulation thresholds. Further animal and human studies of this technique are recommended.
