Electrodiagnostic studies are powerful tools used to objectively examine the physiologic status of a nerve. These consist of nerve conduction studies, which directly examine motor and sensory function of the nerve, and electromyography, which examines spontaneous and voluntary motor unit action potentials in the muscle. Together these studies enable(More)
A technique for producing graded spinal cord compression injuries in rats is described. A metal plate 2.2 x 5.0 mm in size is applied to the exposed spinal dura and loaded with weights. Neurological function is tested postoperatively on an inclined plane. Reading of the maximal angle of rat performance on this plane was found reproducible on comparison(More)
With UAVs becoming more prevalent in public airspace and less expendable, they need to be reliable to avoid any catastrophic events. For this reason the reliability of the Ultra Stick 120 is being analyzed for the UAV lab group at the University of Minnesota-Twin Cities, with the requirement that the reliability be improved by a factor of ten in a redesign(More)
The symptomatology in the thoracic outlet syndrome is well known. A patient is reported in whom the finding of a unilateral pulse deficit was the alerting sign that led to the correct diagnosis. Angiography, performed with injections during different respiratory phases, visualized the pathogenetic mechanism underlying some of the clinical findings.
