Carpal tunnel syndrome and nerve conduction studies in fibromyalgia patients

Introduction: The aim of this study is to evaluate ENMG results of female patients with Fibromyalgia Syndrome (FMS) with a preliminary diagnosis of carpal tunnel syndrome (CTS) and to examine whether there are differences in ENMG results compared to control group. Material and methods: Ethical approval was obtained for this study on 30.12.2022 with number E. Kurul-2022-20/32 and recorded retrospectively between January 2021 and January 2023. 201 female patients who were diagnosed with FMS in Physical Therapy and Rehabilitation polyclinic and who were requested to have ENMG testing with a preliminary diagnosis of CTS were included in study as patient group. 201 patients were included as control group. Results: While number of patients with right CTS was 39 (25.49%) in the FMS group, number of patients with right CTS was 38 (24.20%) in control group. While number of patients with left CTS was 34 (25%) in the FMS group, number of patients with left CTS in the control group was 36 (24.65%). When we analyzed a total of 592 ENMG results in our study, we found a high normal ENMG rate of 75%. Conclusion: We found that there was no difference between the FMS and the control group in terms of compatibility between the pre-diagnosis and electroneurophysiological diagnosis in the ENMG results requested with the pre-diagnosis of CTS in our study. The ENMG examination should be requested for right patient in right indication, by first evaluating the patient well.
