AB0950 Is There a Relation Between Neuropathic Pain and Electrophysiologic Findings in Carpal Tunnel?

BackgroundCarpal tunnel syndrome (CTS) is the most common and well-described compression neuropathy of the upper limb. Scales like DN4 (Douleur Neuropathique 4) and LANSS (Leeds Assessment of Neuropathic Symptoms and Signs) are frequently used to determine pain mechanism (neuropathic and/or nociceptive). To the best of our knowledge, there is no existing study investigating neuropathic complaints and it's relation between electrophysiologic changes after single local steroid injection in CTS.ObjectivesWe tried to find out if there is a relationship between DN4/LANSS score changes and electrophysiologic changes after single local steroid injection.Methods41 participants diagnosed clinically and electrophysiologically with idiopathic CTS between the ages of 20-65 years were included in the study. LANSS and DN4 neuropathic pain scales were used to identify neuropathic pain and patients with neuropathic complaints (DN4 ≥4 and LANSS ≥12) were received local steroid injection into the carpal tunnel. Tests were repeated 2 months after the injection.ResultsWhen compared to pre-treatment results a moderate correlation was observed between SNAP (Sensory Nerve Axon Potential) changes and DN4 scores (p
