Abstract
✓ Percutaneous dorsal column stimulation was done as a screening procedure in 34 candidates before implantation of a permanent dorsal column stimulator for the treatment of intractable pain. This procedure was useful in forecasting the tolerance of the patient to the “vibratory sensation” produced by a dorsal column stimulator, and the efficacy of the device in relieving pain. Eight patients termed the “vibratory sensation” intolerable. Sixteen found it unpleasant but preferable to the pain, and two found it actually pleasant.
