Spinal cord stimulation in the treatment of spasmodic torticollis.
This report presents our observations in 63 patients undergoing chronic spinal cord stimulation for treatment of spasmodic torticollis. In this series there were 23 patients (36.5%) who demonstrated marked improvement, characterized by no evidence of torticollis, full range of motility of the head and neck and no pain. Moderate improvement was found in 20 patients (31.8%) who showed minimal residual torticollis, but had full motility and no pain. There were 5 patients (7.9%) considered mildly improved who demonstrated decrease in their torticollic position, spasms and pain, but retained some element of torticollis and/or some limitation of motility. Correlations were made demonstrating the effect on the results of age, sex, electrode array, the configuration of the applied field and the parameters of stimulation.
