The complications associated with 92 dorsal column stimulator implants are reported. They were of two types, technical and functional. ⋯ Late failure in stimulation was observed in 32 implants that had given excellent pain control for periods ranging from months to years. Improvements in the results of this procedure may be achieved by future technical developments and by clarification of physiological mechanisms.

Transcutaneous electrical nerve stimulation in chronic pain after peripheral nerve injury.
Transcutaneous electrical stimulation was tested in 24 patients with chronic pain following a peripheral nerve injury in an extremity, in 10 patients with a good effect. All of these 10 patients displayed signs of increased sympathetic activity in addition to hyperalgesia. ⋯ Sympathetic block did not relieve the pain in this group. Transcutaneous electrical stimulation should be tried as an alternative to sympathectomy in causalgia major or minor.

Electrical stimulation of the nervous system for pain control.
Transcutaneous electrical stimulation appears to be a valid technique for the treatment of many pain states. Its use in chronic pain is limited and it appears to be much more likely to be effective in the relief of acute painful states. Nevertheless, since it provides a simple way to treat a significant number of patients whose pain would otherwise by intractable, it has been a valuable addition to the armamentarium of the physician dealing with chronic pain. ⋯ Spinal cord stimulation could act through a retrograde effect upon a dorsal horn gate or have more central actions. Brain stimulation in the opiate receptor system may be effective through activation of this system. The mechanisms of action of stimulation in the sensory system centrally are certainly not well understood (Bloedel 1974).

Transcutaneous electrical neurostimulation: a new therapeutic modality for controlling pain.
Transcutaneous electrical neurostimulation relieves chronic and acute pain by blocking the transmission of pain impulses with comfortable electrical stimulation of light touch sensation. The original Gate Control Theory of Melzack and Wall provides a working model to explain the significant pain relief afforded patients. As high as 80% of selected patients presenting with a wide variety of causes could achieve some relief after treatment. This comfortable, safe method is finding wide application in clinical practice.
