Background: Lumbar radiculopathy is a nerve root disorder whose correct diagnosis is essential. The objective of the present study was to analyze the reliability diagnostic validity of eight neurodynamic and/or orthopedic tension tests using magnetic resonance imaging as the Gold Standard. Methods: An epidemiological study of randomized consecutive cases which was observational, descriptive, transversal, double blinded and was conducted following the Standards for Reporting Diagnostic accuracy studies (STARD) declaration. The sample size was 864 participants. Internal and external validity (CI = 95%) and reliability, were calculated for all tests performed independently. The diagnostic validity of the combined and multiple tests in parallel was also calculated. Results: The analysis indicated that only two tests performed independently had external validity, but neither had reliability or precision. The Straight Leg Raise test and the Bragard test performed in a multiple parallel way showed high sensitivity (97.40%), high negative predictive value (PV− 96.64%) and external validity (Likelihood Ratio− 0.05). The combined test of the Slump test and the Dejerine’s triad had internal and external validity. Conclusions: The Straight Leg Raise test and the Bragard test performed in a multiple parallel way and the combined test of the Slump Test and the Dejerine’s triad have clinical validity to discard lumbar or lumbar-sacral radiculopathy.
