Levodopa has been used to treat some painful conditions and found to be effective in neuropathic pain due to herpes zoster in a double-blind study. From our anecdotal observations about the efficacy of levodopa on diabetic neuropathic pain, we designed a double-blind placebo-controlled study to test levodopa in painful diabetic neuropathy. Twenty-five(More)
Electrical stimulation (ES) of lumbosacral nerve roots using a needle electrode inserted to the laminar level at the midline of Th12-L1 or L1-2 intervertebral interspace, was compared with magnetic stimulation using a 9-cm diameter coil (MCS) at the L3-4 or L4-5 spine levels, Compound muscle action potentials (CMAP) were superficially recorded from(More)
Background and Purpose The aim of this study is to evaluate the role of motor-evoked potentials (MEPs) in predicting functional recovery of hemiparesis and hemiplegia in acute stroke patients. Methods Twenty-seven acute stroke patients were evaluated clinically and electrophysiologicaUy within the first week and 3 to 6 months after the event. Ginical(More)
Juvenile myoclonic epilepsy (JME) is not an uncommon seizure disorder, occurring in 5-10% of epileptic patients. A subclinical anterior horn cell involvement has been suggested in some JME patients by concentric needle electromyography (EMG) and turn/amplitude analysis. In this study, 22 JME patients and 17 normal control subjects have been studied with(More)
To evaluate electrophysiological incidence and the type of peroneal nerve lesions seen after high tibial osteotomy we conducted an electrophysiological study (electromyography and nerve conduction velocity studies) in 11 patients who were suffering from medial gonarthrosis and treated by Maquet barrel-vault type high tibial valgization osteotomy. All the(More)
Transcranial electrical or magnetic stimulation was performed in 47 experiments on 42 normal adult subjects. Surface compound muscle action potentials were recorded from the antagonistic tibialis anterior (TA) and soleus (SOL) muscles. A stable late response recorded from SOL during voluntary ankle dorsiflexion is described and called soleus MEP-80. Its(More)
Needle electrical stimulation of the lumbosacral roots at the laminar level of the Th12-L1 or L1-2 intervertebral spaces were performed in 24 normal subjects and 58 patients with various kinds of lumbar radiculopathy (unilateral L4, L5 and S1 herniated nucleus pulposus and lumber stenosis). The root stimulation method was compared with conventional needle(More)
The authors report the clinical review of 20 childhood cases with Friedreich's ataxia. The mean age at onset of symptoms was 6.1 years. The main presenting symptom was abnormal gait (100%). Ataxia of gait and limbs and depressed or absent tendon reflexes were found in all cases. Clinical findings are in accordance with the findings of Harding and Werdelin.(More)
STUDY DESIGN This prospective study includes normal control subjects and patients with focal lesions of the spinal cord investigated by transcranial magnetic stimulation. OBJECTIVES To establish a stable method to elicit motor evoked potentials from cervical to lumbar segmental levels and to apply the method that would allow the localization in patients(More)
