Pre- and postoperative motor conduction times, measured using magnetic stimulation, in patients with cervical spondylosis.

Motor conduction time (MCT) between head and neck in pathways to abductor digiti minimi was measured pre- and postoperatively in 15 patients. There was a significant improvement in MCTs in patients with myelopathy who improved clinically, but preoperative MCTs provided no clear, predictive information. Magnetic stimulation may be of value in quantifying motor function before and after surgery in patients with cervical spondylosis.
