Bipolar spinal cord stimulation for spasmodic torticollis.
Applied Neurophysiology
|January 1, 1985
Summary
Electrical stimulation of the cervical cord offers significant relief for spasmodic torticollis. This non-destructive treatment improved head posture and reduced pain in most patients, with lasting results observed over time.
Area of Science:
- Neurology
- Neurosurgery
- Rehabilitation Medicine
Background:
- Spasmodic torticollis is a debilitating condition characterized by involuntary neck muscle contractions.
- Current treatments for spasmodic torticollis have limitations, necessitating exploration of novel therapeutic approaches.
Purpose of the Study:
- To evaluate the long-term efficacy and safety of chronic electrical stimulation of the cervical cord in patients with spasmodic torticollis.
Main Methods:
- 18 patients with spasmodic torticollis underwent permanent 1,100-Hz electrical stimulation targeting the C2-C4 cervical cord levels.
- Patient outcomes were assessed based on improvement in head posture, reduction in muscular tension, and pain levels.
Main Results:
- Marked improvement was observed in 50% of patients, with satisfactory results in 27.8% and unsatisfactory outcomes in 22.2%.
- Significant reductions in muscular tension and pain were reported within 8 days to 4 months post-stimulation.
- Objective, measurable improvements in head posture required 8-12 months of continuous stimulation.
Conclusions:
- Chronic electrical stimulation of the cervical cord is a safe and reversible treatment option for spasmodic torticollis.
- The procedure demonstrates potential for substantial improvement in symptoms, although objective postural correction may require prolonged stimulation.
