BACKGROUND: Several studies have analysed the use of the Upper Limb Neurodynamic @entity5482 (ULNT1) for diagnosing @entity923 ( @entity923 ) obtaining weak diagnostic accuracy, which could be related to the lack of consensus in the selected diagnostic criteria of ULNT1. OBJECTIVE: To determine the concurrent validity of ULNT1 in comparison to Nerve Conduction Studies (NCS) for the diagnosis of @entity923 , considering the structural differentiation (SD) as an essential part of the diagnosis. DESIGN: Prospective diagnostic test study. METHODS: Individuals with suspected @entity923 referred for NCS were invited to voluntarily participate in the study. Each @entity1 was tested with NCS and ULNT1. ULNT1 result was considered positive when the @entity1 's clinical symptoms were reproduced during the test and symptoms changed during contralateral neck side bending (SD). RESULTS: 58 @entity1 (17 @entity1 , 44 @entity1 ) with suspected @entity923 and a total of 95 limbs were examined using the NCS and ULNT1. Sensitivity of the ULNT1 was 57.9%, specificity was 84.2%, and the positive and negative likelihood ratios were 3.67 and 0.50 respectively. CONCLUSION: Results obtained in the study may indicate the ability of the ULNT1 to generate small shifts from pre-test to post-test probability. However, imprecision in the CIs limits interpretation from the data. LEVEL OF EVIDENCE: 1b.
