RESUMO
OBJECTIVE: We observed the nature of ipsilateral weakness, not hemiplegic side after stroke. And we studied correlation between ipsilateral weakness and neurologic recovery of hemiplegia. METHOD: This study was prospective, follow-up clinical trial. Ipsilateral motor power was checked serially in 20 subjects using Nicholas Manual Muscle Tester (NMMT) (shoulder abduction, wrist extension, hip flexion, ankle dorsiflexion). The subjects are first attacked hemiplegic stroke patients. Other outcome measures are Mini-mental Status Examination (MMSE) and National Institutes of Health Stroke Scale (NIHSS). We studied correlations between motor power recovery in ipsilateral limbs and recovery of neurologic impairment in hemiplegic limbs of stroke patients through SPSS 7.0 program. RESULTS: Ipsilateral motor power in early stage stroke patients is significantly low compared with that of normal subject except ankle dorsiflexion (p<0.05). Comparing ipsilateral proximal with distal limbs power in pre and post multidisciplinary rehabilitation program, upper proximal part recovered faster than the distal part, but which was not statistically significant. Recovery of ipsilateral upper proximal and distal limb weakness is associated with neurologic recovery in hemiplegic side. CONCLUSION: After the stroke, ipsilateral upper limb motor weakness does occur and which follows similar neurologic recovery pattern to the hemiplegic side. Ipsilateral cortical and subcortical tracts take effect on the neurologic recovery of contalateral side.
