Correlation between Findings in Physical Examination, MagneticResonance Imaging, and Nerve Conduction Studies inLumbosacral Radiculopathy Caused by Lumbar IntervertebralDisc Herniation

*e aim of this study was to find out the correlation between magnetic resonance imaging (MRI) and nerve conductionstudies’ (NCS) findings in patients with lumbosacral radiculopathy caused by lumbar intervertebral disc herniation. In addition,the study aimed at finding the correlation between the clinical manifestations of lumbosacral radiculopathy and both MRI andNCS.PatientsandMethods. *e study was a cross-sectional analytic study which included thirty patients with a history suggestiveof lumbosacral radiculopathy. Inclusion criteria were as follows: patients who had an MRI confirmed L4/5 and/or L5/S1 in-tervertebral disc prolapse in addition to one or more of the following (dermatomal distribution of symptoms appropriate withMRI level, presence of motor weakness, sensory impairment, absent ankle jerk, or positive straight leg raising test). All patientsunderwent clinical assessment and NCS, and their MRI examination was reviewed. *e Chi-Squared/Fisher’s exact test was usedto test the correlation.Results. *ere was a statistically significant correlation between abnormal physical findings and nerve rootcompression in MRI. Statistically significant correlation was neither found between abnormal physical examination findings andabnormal NCS nor between nerve root compression in MRI and abnormal NCS findings.Conclusion. Abnormal neurologicalexamination findings can be used to predict nerve root compression in MRI examination. On the contrary, positive findings ofphysical examination do not predict abnormal NCS, as well as negative findings do not exclude abnormal NCS; therefore, it isuseful to add NCS when MRI findings do not match clinical examination findings or when no neuroimaging abnormalities canbe identified.
