Objective

Background BACKGROUND: An examination of EMG is an extension of neurological examination, but its contribution to the diagnosis and management of inpatients is not often reported in the literature.

Design/Methods DESIGN/METHODS: A retrospective analysis of 406 examinations performed in 2007, in hospitalized patients in the HC-UFPR, disclosed 210 EMG performed in 204 inpatients that were studied correlating suspect(s) clinic(s) and outcome. Such correlation was classified as a confirmatory, new diagnosis, incidental findings, inconclusive or normal. When necessary, medical records were reviewed for additional information.

Results RESULTS: The sample consisted of 204 patients (81 female and 123 males), aged between 4 months to 91 years, with mean age of 38 years. Five patients repeated EMG (one repeated twice) in the same. The clinical suspicions was sorted by topography with 14% for motor neuron involvement, 14% nerve root, peripheral nerve 40%, 8% neuromuscular junction and 24% by muscle involvement. Correlation was considered confirmatory in 61%, new diagnosis in 9%, incidental 5%, inconclusive 3% and normal 22%. Motor neuron diseases were most often confirmed by EMG (73%) and neuromuscular junction diseases had more normal result (53% normal result and 29% was confirmatory). Examinations performed for suspected peripheral neuropathy was confirmatory in 64% and had normal results in 17%, mainly in patients under investigation by ataxia and when pain manifestation prevailed.

Conclusions CONCLUSIONS: This study showed that perform EMG is important in the evaluation of inpatients, mainly when suspected motor neuron disease. Although the EMG is an extension of neurological examination, 9% had a new diagnosis. The commonest technical of EMG contributes little to painful neuropathy.
