Reversible prolongation of motor conduction time after transcranial magnetic brain stimulation after neurogenic claudication in spinal stenosis.

Study Design: A consecutive and controlled cohort study.

Objectives: To assess the value of motor conduction time (MCT) between cortex and symptomatic leg muscles after transcranial magnetic brain stimulation as an indicator of reversible root ischemia in patients with neurogenic claudication in spinal stenosis.

Summary Of Background Data: Neurogenic claudication in spinal stenosis is thought to result from transient ischemia of active nerve root fibers.
