RESUMO

OBJECTIVE: To investigate the effect of action related visual and auditory stimuli on the motor evoked potential (MEP) of hand. METHOD: Right handed fifteen healthy adults without neurological deficit were included. Visual lingual stimulation was given on the computer monitor with the sentence and auditory lingual stimulation was given 10 repetitions of the above sentence using computer speaker with eyes closed. MEPs from transcranial and transcervical magnetic stimulation were recorded on the abductor pollicis brevis of the right hand. RESULTS: The latency of MEPs was shortened and the amplitude of MEPs with transcranial magnetic stimulation after lingual stimulation (p<0.05). However, the latency and amplitude of with transcervical stimulation did not show significant changes. CONCLUSION: Cortical excitability was enhanced by action related visual or auditory stimuli. Exercise accompanied by visual or auditory lingual stimulation rather than simple exercise might be useful for facilitating cortical excitability.

RESUMO

OBJECTIVE: To evaluate the effects of high frequency repetitive transcranial magnetic stimulation (rTMS) of the affected hemisphere on the motor recovery and spasticity in chronic post-stroke hemiplegic patients. METHOD: Thirteen chronic stroke hemiplegic patients were randomized to receive real and sham rTMS. rTMS was carried out 10 times at a frequency of 10 Hz with 10 s stimulation followed by 50 s rest, totalling 1,000 stimulations to the affected primary motor cortex using an intensity of 100% of resting motor threshold of unaffected hemisphere. Median nerve H-reflex, modified Ashworth scale (MAS) at elbow and wrist, and manual function test (MFT) were measured at baseline and after 2 weeks of treatment. RESULTS: High frequency rTMS resulted in increased H-reflex latency and decreased H-reflex amplitude and H/M ratio. Also MAS decreased and MFT score increased after 2 weeks of treatment. CONCLUSION: High frequency rTMS in the affected motor cortex might facilitate motor recovery and reduce spasticity in chronic stroke patients.

RESUMO

OBJECTIVE: To investigate the effect of environmental enrichment on the cognitive and motor development in the experimental hypoxia-ischemic encephalopathy neonatal rat model. METHOD: Hypoxic-ischemic encephalopathy models were made in neonatal Sprague-Dawley rats at 3 days of age by ligating the unilateral carotid artery followed by inhalation of 8% oxygen and raised in the enriched environment (n=10), treadmill exercise (n=8) and non-stimulation (n=10) from the 3rd to 8th weeks of age. Neurobehavioral and histopathological changes were compared. RESULTS: The neurobehavioral tests of the rats with hypoxic-ischemic encephalopathy showed prolonged latencies of achievement for cliff avoidance and negative geotaxis (p<0.05). Persisting abnormality into adult life of limb placing improved in exercise and enriched environment groups and spatial learning and memory in a water maze recovered in the rats with enriched environment (p<0.05). The density of dendritic spine increased in the hippocampus with enriched environment (p<0.05). CONCLUSION: The present study supports the possibilities of the positive effects after the enriched environment in the developing brain with hypoxic injury.

RESUMO

Severe hypoglycemia leading to permanent brain damage is rare in non-diabetic population. We present one case where chronic alcoholism combined with prolonged fasting lead to such a state. A 51-year-old male patient, a chronic alcoholic, was found unconscious and brought to the emergency room. At the time of hospitalization, consciousness was stupor and he had a blood glucose of 5 mg/dl and MRI of the brain showed high signal density of the inner temporal gyrus and both hippocampus in T2 weighted imaging. There was no history of diabetes. After two months of rehabilitation, improvements were showed to Rancho Los Amigos recognition scale IV, fair grade of muscular strength in upper and lower limbs, FIM score of 21, and dysphagia was improved and nutrition supply was intaken orally. An alcoholic for a long period of time without adequate nutrient supply was experienced to develop into hypoglycemic encephalopathy and therefore reported.
