SOMATOSENSORY AND MOTOR EVOKED-POTENTIAL CHANGES IN PATIENTS WITH POTTS PARAPLEGIA

The evoked potential changes in patients with Pott's paraplegia have n ot been reported in the literature. We conducted median and tibial som atosensory evoked potential (SEP) and central motor conduction studies to the upper and lower limbs in seven patients with this condition. T he patients' age ranged from 20 to 71 years; four were males. The vert ebral involvement was commonest in the lower thoracic region (4), and a cold abscess was present in five of the patients. Central motor cond uction time (CMCT) to the lower limbs was unrecordable in 3 (six sides ) and prolonged in 3 patients (four sides). The tibial SEP was unrecor dable in 4 patients (seven sides). Motor evoked potentials and SEP cor related with respective motor and sensory impairments, as well as with the outcome.
