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)
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)
The authors report a clinical review of 16 childhood cases with early-onset cerebellar ataxia with retained tendon reflexes. The preservation of tendon reflexes distinguishes this disorder from Friedreich's ataxia. The mean age of onset of symptoms was 7.1 years. The main presenting symptom was abnormal gait (100%). Ataxia of gait and limbs and normal or(More)
Twelve patients with recurrent cranial nerve palsies in whom no focal cause was found were seen during a period of 4 years. The literature is reviewed, and the relationship and similarity to Tolosa-Hunt syndrome is discussed. Early recognition is important since the response to steroids, although not specific, is rapid in most patients, and the prognosis(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)
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)
It is known that myasthenia gravis is improved by cold. In two previously reported studies performed on a limited number of myasthenic patients and controls, local cold application to the eyelid was suggested for use as a diagnostic test for ocular myasthenia gravis. In this study, ice test to the eyelid was evaluated as a diagnostic test on 12 myasthenic(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)
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)
