Description
Summary:Abstract Objective Quantitative sensorial tests (QST) are used for evaluating specific sensorial nerve function. In this study, QST and magnetic resonance imaging (MRI) findings are compared in lumbar disc herniation patients, and the accuracy of QST data was investigated. Material and Methods Sixty-four patients between 18 and 70 years of age suffering from radicular pain with positive Lasegue’s test were included in this study. Specific criteria included complaints due to L5 discopathy. MRI findings were classified according to the Pfirmann grading system, and QST was applied to the L5 dermatoma of both symptomatic and nonsymptomatic legs of all patients. Vibration detection threshold, heat detection threshold, cold detection threshold, and heat pain detection threshold values were obtained, and MRI findings were classified according to the Pfirmann grading system. Results When we compared the symptomatic and nonsymptomatic legs of participants, there were significant differences by means of all QST parameters (0 = 0.00). In a comparison of the QST and MRI Pfirmann grading systems, there is also a strong parallel statistical correlation between the Pfirmann grade and QST parameters (P
