Normal subjects were used to evaluate a fiber optic instrumented glove for semi-automated goniometric measurement. The glove electronically records and transmits hand and finger position to a host computer by measuring the amount of joint flexion. The glove was put through a series of range-of-motion (ROM) tests with five subjects. Metacarpal (MP) and(More)
A study was conducted to compare the regeneration of rat peroneal nerves across 0.5 cm gaps repaired with artificial nerve grafts (ANG) versus sutured autografts (SAG). The ANG model is composed of a synthetic biodegradable passive conduit made of glycolide trimethylene carbonate (GTMC) filled with a collagen matrix (predominantly Type I collagen, derived(More)
The purpose of this study was to test the hypothesis that a heat-and-moisture-retaining mask would result in a significant decrease in respiratory water loss among healthy subjects sleeping in a cold environment. The study was done in a backyard near a tertiary-care center during winter nights with ambient temperatures of less than 0 degrees C. Subjects(More)
—Worst-case execution time analysis is the funda-ment of real-time system design, and is therefore an area which has been subject to great scientific interest for a long time. However, traditional worst-case execution time analysis techniques assume that the underlying hardware is a mono-processor system, and this class of hardware platforms is getting less(More)
A study was made to compare the regeneration of rat peroneal nerve across a 0.5 cm gap repaired with a sutured autograft (SAG) versus an artificial nerve graft (ANG). The ANG model is composed of a synthetic biodegradable passive conduit made of polyglycolic acid (PGA) and a synthetic growth medium composed of hypoallergenic collagen. Axonal regeneration in(More)
Current methods of peripheral nerve repair are to directly suture cut nerve stumps, or to bridge large gaps with an autograft repair. Autograft-associated problems include donor site morbidity and limited supply. Many of the present limitations of nerve repair might be overcome by expanding the patients own Schwann cells in vitro, then combining the cells(More)
By attenuating neural and perceptual responses to sustained stimulation, adaptation enhances the detection of new, transient stimuli. Disadaptation serves a similarly important role as a temporal filter for chemoreceptor cells, producing rapid recovery of sensitivity upon termination of the adapting odorant. Previous research from our laboratory indicated(More)
Many of the present limitations of peripheral nerve repair might be overcome by performing nerve repairs at the axon level. One approach to nerve repair at this level would be to implant a neuroprosthesis in the form of a microelectronic switchboard which could route the connections of regenerated axons to their correct destinations. This requires a merger(More)
Peripheral nerves are transected in many traumatic injuries of the extremities. Satisfactory functional regeneration of such nerves often fails to occur after repair with sutures. Possible reasons for these failures include poor alignment of nerves or fascicles, intrusion of scar tissue into the nerve junction, and outgrowth of nerve tissue from the repair(More)
