RESUMO
This study was undertaken to evaluate the motor dysfunction on the nonhemiplegic side in patients with acute intracerebral haemorrhage (ICH) and correlate these with radiological and motor evoked potentials findings. 28 patients (23 males, 5 females), with CT proven ICH within 10 days of ictus were subjected to clinical evaluation and central motor conduction studies (CMCT) of upper limbs. The patient's age ranged between 28 and 84 years. Motor signs on the nonhemiplegic side were present in 17 patients in the form of increased tone (10), hyperreflexia (13) and extensor plantar response (10). Sixteen of these patients had severe weakness on the hemiplegic side. Most of the patients had putaminal haemorrhage (13) and thalamic and lobar haemorrhage was seen in 2 patients each. The motor dysfunction on the nonhemiplegic side correlated with midline shift but not with the size of haematoma. CMCT findings correlated with motor signs on the nonhemiplegic side in 6 patients. In the patients without any signs on the nonhemiplegic side, CMCT was normal. Out of 17 patients with motor dysfunction on the nonhemiplegic side 9 revealed improvement in CMCT at 1 month followup. The patients with CMCT abnormalities on the nonhemiplegic side either died (2) or had poor outcome (9). Motor dysfunction on the nonhemiplegic side may be due to tentorial herniation and suggests a poor outcome.
