BACKGROUND AND PURPOSE Current guidelines for commercial motor vehicle (CMV) drivers to return to driving after a TIA or stroke was last reviewed in 1988. Updated recommendations are presented based on recent evidence. METHODS A 3-member medical expert panel chosen by the U.S. Department of Transportation's Federal Motor Carrier Safety Administration used findings of systematic literature rev...

BACKGROUND Successful return to work is regarded as one of the most important outcome factors for working-age post stroke patients. The present study will estimate the effect of various predictors on the odds of returning to work after stroke. Nearly twenty thousand 20-57 year-old stroke patients in Denmark who were gainfully occupied prior to the stroke will be included in the study. METHODS...

[1] Vertical electric field waveforms due to dart leader/return stroke sequences measured on the ground 15 and 30 m from the negative lightning channel are used to examine the so-called residual electric field, the difference between the leader electric field change, and the following return stroke electric field change. At these distances, no residual field is expected if the return stroke neu...

A WC-130 aircraft was used as an airborne platform for broadband electric and magnetic field sensors to measure the surface fields on the airframe from lightning strikes in li.r 7 35 km range. The waveforms were recorded digitally, with a «ample interval of 20 nsec and a time window of 164 microseconds. Since the aircraft was above 15,000 feet, and the lightning source was relatively nearby, th...

High-speed video data were used to analyze the initiation and propagation of 36 needles their associated 306 flickering events observed in a single-stroke positive cloud-to-ground (+CG) flash. The occurred during return-stroke later stage continuing current, within approximate 10 ms after onset +CG return stroke. They initiated near lateral surface predominantly horizontal channel extended almo...

OBJECTIVE We studied the variable effects of norepinephrine infusion on cardiac output in postoperative cardiac surgical patients in whom norepinephrine increased mean arterial pressure. We hypothesized that the directional change in cardiac output would be determined by baseline cardiac function, as quantified by stroke volume variation, and the subsequent changes in mean systemic filling pres...

OBJECTIVE To describe the current scientific evidence of recovery and return to activity following exertional heat stroke (EHS). DATA SOURCES Information was collected using MEDLINE and SPORTDiscus databases in English using combinations of key words, exertional heat stroke, recovery, rehabilitation, residual symptoms, heat tolerance, return to activity, and heat illness. STUDY SELECTION Re...

Introduction Return-to-work is a key rehabilitation goal for many working aged stroke survivors, promoting an overall improvement of quality life, social integration, and emotional wellbeing. Conversely, the failure to return-to-work contributes loss identity, lowered self-esteem, isolation, poorer life health outcomes. programmes have largely focused on physical vocational rehabilitation, whil...
