Abstract

Abstract: Objective To investigate the change of current perception threshold (CPT) in patients with lumbar radiculopathy. Methods From September, 2014 to October, 2015, 86 patients with lumbar radiculopathy from lumbar disc herniation were measured with CPT in different frequencies (5, 250 and 2000 Hz) on proximal and distal points of affected dermatome of both legs. Results The CPT grades of both proximal and distal points were higher in the affected legs than in the contralateral legs (t=1.659, P<0.001). The abnormal CPT grades counted for 46.36% for both points, 35.45% for only distal points and 35.45% for only proximal points. CPT was abnormal in all the patients, and 93.6% of them appeared at 250 Hz, 57.4% at 2000 Hz, and 29.8% at 5 Hz.Conclusion CPT is sensitive in lumbar radiculopathy, especially in multiple frequencies and test points.
