[Electromyografic patterns predictive of motor evolution in neuroschistosomiasis]

Neuroschistosomiasis in myeloradicular pattern is frequently observed in patients from Northeast of Brazil. Despite of this, the evolution of neurologic and electromyographic patterns is not well studied in this group of patients. The aims of this study were to describe and compare the clinic and electromyographic abnormalities of patients with neuroschistosomiasis and radicular involvement. We analyzed 21 electromyographic exams of the lower limbs carried out in the initial presentation of the disease. Electromyographic pattern of 95.2% of patients was compatible to axonal lumbosacral multirradiculopathy, with variable denervation extension, but predominantly from levels L2 to S2. There was variable degree of deficit in the lower limbs, and the follow-up of motor disturbances was better more frequently when the roots were involved in smaller number. Electromyography should permit to know the motor prognosis of patients with myeloradiculitis due schistosomiasis.
