RESUMO

Foram estudadas as alterações eletrofisiológicas em 135 pacientes com síndrome do canal carpeano, num total de 270 mãos. As medidas das velocidades de condução sensitiva foram as alterações mais freqüentes, seguidas das alterações de condução motora e eletromiográficas.
A técnica da medida de condução sensitiva estimulando a palma da mão e captando o potencial evocado acima do punho mostrou ser a mais sensível para o diagnóstico precoce da SCC.


SUMMARY

One hundred thirty five patients with carpal tunnel syndrome were studied trough electrophysiological techniques. Nerve sensory conductions, motor conductions and electromyography were performed in all patients and the results discussed. The authors call the attention for the technic of sensory conduction stimulating palma and picking up the potentials on the wrist as the most sensitive technic for the early detection of carpal tunnel syndrome.
