Objective: To analyse the distribution of age, sex, referring physicians, clinical problems, electrodiagnostic evaluation, and electrodiagnostic results of electrodiagnostic use in Songklanagarind Hospital in the fiscal year 2003.
Material and Methods: The EMG registration book and electrodiagnostic reports in the fiscal year 2003 were reviewed. The data consisted of age, sex, clinical problems, referring physicians, the electrodiagnostic evaluation, and the electrodiagnostic results.
Results: There were more female (52.6%) than male (47.4 %) patients, with 22.5% in the middle age group (40-50 years old). The most common clinical problem for which they were referred for electrodiagnostic evaluation was numbness (47.6 %). Most of the patients were referred from an orthopedic physician (42.3%) and the nerve conduction study was the test that was done most frequently (83.1%). Polyneuropathy was the most frequent conclusion from electrodiagnostic evaluation (45.9%).
Conclusion: Electrodiagnosis can be an extension of the history and physical examination, assisting the physician to narrow down the differential diagnosis and confirm the diagnosis.
