with a Novel Composite Nerve
Conduction Measurement
Spine. 2002;27(24):2811-9.
Study Design
• 60 Subjects
• 25 Subjects with both MRI and clinically
confirmed lumbosacral radiculopathy and 35 asymptomatic subjects
• Comparison
of NC-stat comprehensive F-wave methodology to lumbosacral radiculopathy confirmed
by MRI and clinical findings
Key Results
• Sensitivity 83%; Specificity
84% for lumbosacral radiculopathy
• Diagnostic Accuracy of 0.91 (area under
ROC curve) for lumbosacral radiculopathy
