We examined Hoffmann (H) and tendon (T) reflexes in 3 populations of adult subjects: acute SCI (< 2 weeks post injury), controls, and chronic SCI (> 1 year post injury). We further investigated the effects of continuous tendon vibration and different stimulus rates on the size of evoked H reflexes in these subject populations. All reflex amplitudes were(More)
OBJECTIVE To examine the autonomic nervous system functions in patients with Huntington disease. BACKGROUND Although patients with Huntington disease frequently experience vegetative symptoms, it is not clear if there is dysfunction of the autonomic nervous system. METHODS Sympathetic skin response (SSR) latency and amplitude from both palms and soles(More)
A 66-year-old man with a 45-month course of chronic inflammatory polyradiculoneuropathy developed a coagulopathy due to an antibody to factor VIII. Despite clinical improvement in the neurologic disease at the onset of the coagulation disorder, antibody to peripheral nerve myelin was demonstrated in high titer. Antibodies to factor VIII and peripheral nerve(More)
Accurate ocular motility recordings were made of the saccadic responses of five patients with Eaton-Lambert syndrome (ELS). It was found that, contrary to common belief, the ocular motor system is affected. The saccades of ELS patients mimicked those of patients with myasthenia gravis (MG). Both groups exhibited hypometria and multiple, closely spaced(More)
The functional effects of three types of therapy for subjects with long-term incomplete cervical spinal cord injuries were investigated. Men and women, aged 18 to 45 years, were assigned to one of four groups using a restricted randomization process. The training period was divided into two consecutive eight-week time blocks where subjects received either(More)
We have studied characteristics of subjects that could potentially influence quantitative sensory measurements in 156 non-neuropathic individuals. All subjects had measurements of vibration perception at the hallux and index finger with the vibration sensitivity tester and measurements of cool and warm perception at the hallux with the thermal sensitivity(More)
The electrical and contractile properties of hand muscles in a selected population of quadriplegic subjects were studied intensively before and after EMG biofeedback. Spontaneously active motor units and units that could only be slowly and weakly activated were observed in these subjects, in addition to units that were voluntarily activated normally. This(More)
Our objective in this study was to compare the sensitivity and specificity of the median sensory nerve conduction velocity (SNCV) from digit 1 to wrist with those of the distoproximal (D/P) ratio of the median SNCV from palm to digit 3/palm to wrist in the diagnosis of mild carpal tunnel syndrome (CTS) by using a receiver operating characteristic (ROC)(More)
Human T lymphotropic virus type I (HTLV-I)-associated myelopathy (HAM) (tropical spastic paraparesis/HAM) has rarely been reported in the United States. We present 10 well-documented cases with positive Western immunoblot test results and polymerase chain reactions for HTLV-I. The clinical and laboratory features of these American-born patients resemble(More)
