This study will prospectively examine the effect of screen time on recovery from concussion. Patients 12 to 25 years of age presenting to the ED with a concussion will be randomized to all...
Childhood obesity is an epidemic and increasing. There are very few effective treatments for obesity in children. Recent studies have shown an association between obesity and sedentary b...
This fMRI study investigates neural correlates of emotion regulation, emotion processing and craving in recreational cannabis users.
The purpose of this study is to explore the effects of an intervention designed to help increase physical activity and decrease screen time.
The purpose of this study is to assess whether the degree of anxiety experienced by women undergoing visual inspection with acetic acid (VIA) and Lugol's iodine (VILI) can be reduced by wa...
The purpose of the present study was to describe the incidence proportion of different types of running-related injuries (RRI) among recreational runners and to determine their time to recovery.
Less is known about how neighborhood environments relate to sedentary time as compared to physical activity. This study examined relations of perceived and objective neighborhood environments with TV ...
Few preschool children meet physical activity recommendations, whereas the majority exceeds screen-time recommendations. The purpose of this study was to examine the relationship of screen-time polici...
Adequate physical activity is associated with improved sleep in adults. Such associations, however, vary greatly across studies in pediatric populations, with no studies involving infants found in the...
This paper determines longitudinal changes in the time Spanish adolescents devote to moderate-to-vigorous physical activity (MVPA) and screen media activity (SMA). Moreover, it examines the displaceme...
Screens which absorb the energy in the x-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less x-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen.
A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector.

The ability to estimate periods of time lapsed or duration of time.
Recording serial images of a process at regular intervals spaced out over a longer period of time than the time in which the recordings will be played back.
Living outdoors as a recreational activity.
