A multichannel functional electrical stimulation (FES) system for the restoration of quadriplegic upper extremity function is described. The system is composed of a personal computer NEC PC-8801mkII, peripheral electronic circuits, CRT display and respiratory sensors for volitional control by the patient, and percutaneous electrodes. A C4 quadriplegic(More)
To investigate the role of immunological reactions in the development of cerebral vasospasm after subarachnoid hemorrhage (SAH), the authors studied the correlation between immune/inflammatory reactions in the arterial wall and the time course of vasospasm in primates. Twenty monkeys were divided into four groups of 5 animals each: 1) a control group of(More)
Seventeen hemiplegic patients with chronic shoulder subluxation secondary to a cerebrovascular accident (CVA) were divided into three groups, two of which were subjected to 6 weeks of therapeutic electrical stimulation (TES) for 15 minutes twice a day, in order to assess the effectiveness of the treatment in reducing subluxation, and in improving shoulder(More)
A 58-year-old man presented with an extremely rare case of "pure type" spinal tanycytic ependymoma associated with hematomyelia manifesting as sensory disturbance of the bilateral hands and weakness of the right arm. Magnetic resonance imaging demonstrated a tumor in the spinal cord from C-2 to C-4 levels. The soft gelatinous tumor was subtotally resected(More)
It is difficult to receive video download services in wireless environments. Some service management schemes to consume network resources effectively from the aspect of user's satisfaction (utility) are proposed. In video download services, user's satisfaction depends on both the latency time and the video quality. Some utility functions for the latency(More)
OBJECT It remains unclear whether elderly patients with compressive cervical myelopathy can be expected to experience a promising surgery-related outcome after undergoing expansive laminoplasty. The purposes of this study were to evaluate the efficacy of expansive laminoplasty in elderly patients with cervical myelopathy due to multisegmental spondylotic(More)
More than half of the patients with glomerulonephritis, nephrotic syndrome and renovascular hypertension showed obviously abnormal profiles of serum lipoproteins (Lps). The abnormal profiles returned to normal or near-normal when the disease was ameliorated or corrected surgically. A unique Lp profile (broad midband pattern, BMP) was observed in(More)
The authors studied the effect of the immunosuppressive drug cyclosporine (CS) on the development of cerebral vasospasm after subarachnoid hemorrhage (SAH) using a primate model of vasospasm. Eighteen monkeys were randomly divided into three groups: a sham-operated control group, an SAH group, and a CS-treated group. To induce SAH, the right side of the(More)
This paper describes the relationship between knee extension force and EMG signals detected by multiple bipolar wire electrodes inserted into the human vastus lateralis muscle under isometric conditions. Six healthy male volunteers participated in this study. Eight pairs of bipolar wire electrodes were inserted into the right vastus lateralis muscle and the(More)
BACKGROUND AND PURPOSE Although it has been suggested that humoral immunity plays a role in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage, there has been no quantitative assay for cellular immunity. We studied the kinetics of immune cells in the subarachnoid space after subarachnoid hemorrhage in the rat. METHODS One hundred(More)
