BACKGROUND Immobilization and associated periods of inactivity can cause osteopenia, the physiological response of the bone to disuse. Mechanical loading plays an essential role in maintaining bone integrity. Skeletal fractures represent one cause of reduction of the physical activity (PA) level in adolescents. The purpose of this study was to quantify the reduction of PA in adolescents with li...

OBJECTIVES To evaluate the reliability and validity of the StepWatch Activity Monitor (SAM) as a reliable and valid measurement tool for assessing ambulatory activity in able-bodied children and to assess the ambulatory activity of able-bodied children. DESIGN Descriptive study. SETTING General community. PARTICIPANTS Ninety-seven able-bodied children, aged 6 to 20 years. INTERVENTIONS ...

BACKGROUND Little is known regarding the relationship between balance impairments and physical activity in COPD. There has been no study investigating the relationship between balance and objectively measured physical activity. Here we investigated the association between balance and physical activity measured by an activity monitor in elderly COPD patients. MATERIALS AND METHODS Twenty-two o...

BACKGROUND Accelerometers are motion-sensing devices that have been used to assess physical activity in dogs. However, the lack of a user-friendly, inexpensive accelerometer has hindered the widespread use of this objective outcome measure in veterinary research. Recently, a smartphone-based, affordable activity monitor (Whistle) has become available for measurement of at-home physical activity...

We propose a system that enables users to write memos directly on a computer screen by hand. The system helps users save the screen images along with a user's handwritten strokes and in searching for them. We describe some of the important functions of the system and the effective retrieval keys for searching for saved images. We explain that the implementation of our prototype system consists ...
