A cross-sectional descriptive study of 133 patients diagnosed with lumbar disc herniation L4-L5 and L5-S1 to evaluate some aspects of the diagnosis. More than two thirds were males for an approximate ratio 3:1. The most affected age groups were 30-39 and 40-49 years in both sexes. The most frequent symptom was lumbar pain (64,7 %); 71 patients progressed with the symptoms for over a year, 42 patients kept symptoms from 6 to 12 months and only 20 kept symptoms for less than 6 months. At the time of diagnosis, signs of prolonged compression were conformed in 86 patients (63,2 %). Electromyography held the first place as far as positive electrophysiological studies are concerned (74,4 %). It was concluded that diagnosis of disease was late and determined electrophysiological alterations of prolonged compression that can not be solved with rehabilitation.
