We are reporting a neurophysiologic analysis of two patients presenting with thoracoabdominal spontaneous muscle jerks. Polymyographic recordings showed myoclonic bursts with onset in the upper rectus abdominis or lower intercostal muscles followed by rostral propagation to the upper intercostal and caudal propagation to the abdominal muscles by slowly(More)
The syndrome of painful legs and moving toes consists of continuous or semicontinuous involuntary writhing movements of the toes associated with pain in the affected extremity. We report a 57-year-old man with a 33-year history of painless and semicontinuous involuntary movements of the toes of the left foot similar to those seen in painful legs and moving(More)
In order to understand which neural elements are excited after percutaneous magnetic coil (MC) stimulation over the cervical vertebral column we have performed such study in 8 normal subjects and 4 patients. On moving the coil rostrocaudally up to 3 cm and horizontally up to 2 cm from the midline we found no change in the latencies of the compound muscle(More)
After verifying the diagnosis of restless legs syndrome (RLS) in 105 patients who are part of a nationwide support group, we undertook a telephone survey of their symptomatology. We then compared the answers with those of 33 of our own RLS patients who had undergone a neurologic examination and had a periodic limb movement in sleep (PLMS) index of > 5(More)
We describe short-term and long-term safety studies after low repetition rate magnetic brain stimulation in 10 normal subjects. We obtained quantitative EEG data, psychometric test results, serum prolactin and cortisol levels before and after brain stimulation. EEG and psychometric data were also obtained in 5 of these subjects 16-24 months after the(More)
The symptoms of restless legs syndrome (RLS) worsen while patients are sitting or lying and also worsen at night. The current study was designed to determine if the periodic limb movements (PLMs) and sensory symptoms of RLS are modulated by an independent circadian factor. We recorded sleeping and waking PLMs and waking sensory symptoms in eight volunteers(More)
We report the physiologic and pharmacologic analysis in two women, aged 18 and 17 years, with essential myoclonus. Both responded to benztropine mesylate and had been functioning normally. The physiologic analysis suggested ballistic movement overflow and audiogenic stimulus-sensitive myoclonus. The pharmacologic study showed a direct and mutual antagonism(More)
Circadian rhythm sleep disorders may occur after traumatic brain injury. We describe a 48-year-old man who presented with sleep onset insomnia and cognitive dysfunction after a car accident. A diagnosis of delayed sleep phase syndrome (DSPS) was confirmed by sleep logs and actigraphy, which revealed sleep onset in the early morning hours and awakening(More)
