Bir Devlet Hastanesi Nörofizyoloji Laboratuvarına Başvuran Olguların Özellikleri ve Klinik Ön Tanı ile Elekromiyografik Tanı Tutarlılığı

Abstract

study, it was aimed to evaluate the characteristics of the patients referred to the secondary level state hospital neurophysiology laboratory by different branches, and to evaluate the compatibility between clinical prediagnoses and electromyographic (EMG) diagnoses. Material and Methods: The results of the EMGs performed by the same physician in the Aydın State Hospital Neurophysiology Laboratory during the 18-month period between 01.03.2014-30.09.2015 were reviewed retrospectively. The agreement between the prediagnosis of the referring clinic and the EMG result information was analyzed. Results: 1620 (64.1%) of the patients with a mean age of 48.5±15 (5-90) years were female. Neurology 1574 (62.3%), physical therapy and rehabilitation (PTR) 534 (21.1%), orthopedics 184 (7.3%), neurosurgery 155 (6.1%) and other branches 81 (3.2%) requested EMG from the neurophysiology laboratory. The prediagnoses of the patients who underwent EMG were; 1027 (40.6%) carpal tunnel syndrome (CTS), 130 (5.1%) cubital tunnel syndrome (CUTS), 452 (17.8%) polyneuropathy (PNP), 467 (18.4%) upper extremity radiculopathy (RDP), 198 (7.8%) lower extremity RDP. When the prediagnosis-EMG diagnosis agreement is examined: in CTS 55.6% rate, moderate agreement; in CUTS 65.4% rate, strong agreement; in PNP 38.5% rate, moderate agreement; in upper extremity RDP 87.1% rate, strong agreement; in lower extremity RDP 81.3% rate, strong agreement were found. 25% of all EMG results were normal. Normal results were found in 27.5% in neurology, 21.7% in PTR, 20.1% in orthopedics, and 11.6% in neurosurgery. In addition, normal results were determined in 27.7% in CTS, 16.2% in CUTS, 48% in PNP, 6% in upper extremity RDP, and 10.6% in lower extremity RDP. PNP was the most common prediagnosis (48%) with a normal result, and it was found to be statistically significant (p<0.001). Conclusion: According to our study; The percentage of normally completed EMG was found to be high, and both clinical findings and department-based prediagnosis-EMG diagnosis agreement were low. When evaluated together with the literature data, we concluded that most EMG examinations are unnecessary.
