CRUZ, MÁRCIA WADDINGTON; CORREA, ROSALIE BRANCO; PUCCIONI-SOHLER, MÁRZIA  and  NOVIS, SÉRGIO AUGUSTO PEREIRA. Electroneuromyography and somatosensory evoked potentials in HTLV-I associated myelopathy. Arq. Neuro-Psiquiatr. [online]. 1998, vol.56, n.4, pp. 756-762. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X1998000500009.

The objective of the present study was to correlate electroneuromyography (ENMG) and evoked potentials findings with clinical aspects and intrathecal synthesis of HTLV-I antibodies production on HTLV-I myelopathy (HAM). Patients were seropositive for HTLV-I by different assays and seronegative for HIV and VDRL. They had no other causes of myelopathy and peripheral neuropathy. Peripheral neuropathy was stablished in 34.3% of the cases by ENMG. Peripheral neuropathy was mostly asymmetric (82%), sensory motor (90%), axonal (54,5%) or of a mixed type (45,4%). In 63.6% of these cases related symptoms were observed. ABR was abnormal in one patient and the PRVEP in 28.5% ,who were symptom-free. The SEP was abnormal in 85.7% of the cases, half of them presenting clinical complaints. In only 14% of the individuals with clinical manifestations, SEP was normal. In 28% of patients with abnormal SEP the ENMG disclosed a peripheral neuropathy.

Keywords : peripheral neuropathy; HTLV-I associated myelopathy; electroneuromyography; somatosensory evoked potentials.
