Negative neurodynamic tests do not exclude neural dysfunction

Background: Neurodynamic tests are frequently used to detect neural involvement in patients with radiating arm or leg symptoms. However, some patients have normal neurodynamic tests despite a clear nerve compromise. A classical example is carpal tunnel syndrome (CTS), in which a subgroup of patients present with normal neurodynamic tests even though electrodiagnostic tests confirm nerve involvement. The question arises why this discrepancy exists and whether there might be a pathophysiological explanation for the presence of negative neurodynamic tests despite a clear diagnosis of neural tissue compromise.
