Diagnosis Confirmation Rates of Desired Electroneuromyography Results with Pre-Diagnosis of Upper Extremity Entrapment Neuropathy

Objective Electroneuromyography (ENMG) is an examination used by clinicians to confirm the diagnosis of patients with suspicion of entrapment neuropathy. The correlation between the ENMG results and requests increases when the clinical examination and anamnesis are well evaluated. This study aims to determine the compatibility of the electroneurophysiological examinations made due to the prediagnosis of entrapment neuropathy at the ENMG Laboratory in the Neurology Clinic and determine whether there is a difference between the clinics that made the requests. Materials and Methods The study complied the examinations made in Canakkale Onsekiz Mart university neurology clinic ENMG laboratory between 01/07/2019 and 21/07/2020, and these examinations were retrospectively scanned. Results: In total, 1464 results were scanned and those who underwent ENMG examination on the entrapment neuropathy protocol (SUT code 703220) were included in the study. Patients for whom requests were made lower extremity entrapment neuropathy and those who were younger than 18 were not included. Information regarding 445 (313 women, 132 men) patients with upper extremity entrapment neuropathy were obtained. The mean age of the patients was 49.5±14.2 (18-89). The study found that among electroneurophysiological examinations made due to the prediagnosis of entrapment neuropathy, 155 (34.8%) were diagnosed with carpal tunnel syndrome, 18 (4.0%) were diagnosed with ulnar nerve entrapment neuropathy, 3 (0.7%) were diagnosed with radial nerve entrapment neuropathy, and 253 (56.9%) had normal results. While there were no significant differences between the rates of normal results in terms of clinics that made the requests. Conclusion: While normal results were obtained on the majority of the electroneurophysiological requests due to the pre-diagnosis of upper extremity entrapment neuropathy, there were no significant differences between the clinics.
