Electrodiagnostic test is a study that gives information about underlying neuromuscular disorder, so practically it is accepted as an extension of physical examination. It aids in the diagnosis and treatment of the disorder, if it is done in appropriate protocole. The more right indication of the claims are, the higher the concordance and the better the clinical benefit. In this study we aim to evaluate concordance ratio of electrodiagnosis with prediagnosis in our Electroneuromyography (ENMG) Unit.

Materials and Methods:

According to concardance between prediagnosis and electrodiagnosis results, the electrodiagnostic requests and ouput in the Electroneuromyography (ENMG) Unit of Namık Kemal University Mecidine Faculty, Department of Physical Medicine and Rehabilitation were evaluated retrospectively, between February 2016- February 2018.


By evaluating prediagnosis and electrodiagnosis, 200 of totally 204 electrodiagnostic study were included in the study. 55 of the requests were male and 145 were female, they were respectively 48,89± 13,41 and 47,62± 13,06 years old. Electrodiagnostic results were: 53 normal, 142 entrapment neuropathy, 28 radiculopathy/plexopathy, 28 polineuropathy, 2 myopathy. In our clinic 26,5% of the electrodiagnostic studies were normal. 73,5% of anormal electrodiagnostic study composed of 61,5% of prediagnosis concordant electrodiagnostic result and 12% of different diagnosis from prediagnosis.


The concordance between prediagnosis and elecrodiagnostic results of electrodiagnostic studies depends on the requests with well defined indications. After anamnesis, physical and neurological examination, the electrodiagnostic test with proper requests and practice is a valuable study in planning the treatment or follow-up of the progression. Request without any indication will decrease the value of electrodiagnostic test and results in elongation of waiting time, unnecessary patient intensity, lost of time and sources.
