Methods: Fourteen patients with spasmodic torticollis were injected with botulinum toxin type A under the guidance of EMG, and their curative effects were analyzed. Results: In 14 cases, the main involvement of sternocleidomastoid, trapezius, paravertebral muscles, head muscle, scapular levator muscle and so on. Of the 14 cases, 3 were markedly effective, 9 were significantly improved, 2 were ineffective, and the effective time was 7 to 10 days. The curative effect lasted for 4 months. CONCLUSION: Electromyogram-guided botulinum toxin type A treatment of spasmodic torticollis is an accurate and safe method.
