Depression of evoked electromyographic (EEMG) responses by propofol in a patient with human T-cell lymphotropic virus type I-associated myelopathy (HAM).

We report a patient with human T-cell lymphotropic virus type I-associated myelopathy. Although muscle strength in both of the upper extremities was normal in this patient, evoked electromyogram of the adductor pollicis was depressed by propofol at the induction of anesthesia.
