BACKGROUND We used MIT-Manus, a robot designed to provide interactive, goal-directed motor activity for clinical neurologic applications. OBJECTIVE To test whether this robotic manipulation of the impaired limb influenced motor recovery in patients with hemiplegia. METHODS Sequential patients with a history of a single stroke and hemiplegia (N = 20)(More)
Glutethimide has been used to control essential tremor. Its efficacy in the treatment of disabling cerebellar and rubral tremor was assessed in an open study of six patients with multiple sclerosis and two patients with traumatic brain injury. Functional and quantitative tremor severity was assessed before treatment and 7 to 14 days after a stable dose was(More)
Mental symptoms increased in frequency among 100 patients with parkinsonism treated with levodopa. Dementia was found in about one-third of patients throughout the 6-year treatment period. Thirteen patients became demented during the study, and dementia worsened severely in seven others. Agitated confusion became increasingly frequent and was observed in 60(More)
Plasma antidiuretic hormone (ADH) levels during head-up tilt were measured in quadriplegic patients and normal healthy subjects. In normal subjects, neither rapid tilt (from horizontal to 70 degrees head-up in 20 seconds and remaining head-up for 5 minutes) nor gradual tilt (from horizontal to 70 degrees head-up over 15 minutes) significantly changed the(More)
We reviewed the histories of patients seen in a large Parkinson's disease clinic from 1983 to 1989 to determine if there is a relationship between the timing of initiation of levodopa therapy and the development of motor response fluctuations, dyskinesias, and dementia. There were no factors predisposing to the development of response fluctuations or(More)
One hundred patients with Parkinson's disease, who started taking levodopa before the end of 1968, have been assessed after 5 years. Forty-seven patients are still being followed on levodopa, and half of them are at least 25% better than at their pretreatment evaluation. However, the average functional rating is returning toward baseline from its remarkable(More)
Seventeen patients with advanced Parkinson's disease who had fluctuations in motor performance while taking standard Sinemet (STD) 25/100 underwent daylong pharmacokinetic and clinical observation studies while taking both STD and Sinemet CR, a new controlled-release formulation containing 50 mg carbidopa and 200 mg levodopa. During treatment with Sinemet(More)
