The aim of die present study was to evaluate different aspects of a device designed to monitor physical activity. Measurements of different axes and placement of the monitor were rested using a treadmill with ranging increments in incline or speed. The monitor was also used to assess the level of ...
We measured physical activity after strenuous exercise in 20 women with chronic fatigue syndrome (CFS), compared to 20 sedentary healthy volunteers who exercised no more than once per week. Activity was measured for 2 weeks using a portable waistworn vertical accelerometer. After the first week of activity monitoring, all participants returned for a ...
We examined the ability of the Computer Science Applications (CSA) accelerometer to predict energy expenditure during treadmill walking and stair stepping in nine children and adolescents with cystic fibrosis (CF) (mean age 12.1 yr, SD + 2.8) and ten healthy controls (mean age 10.8 yr. SD + 2.2). The accelerometer was attached above the hip and ...
The authors examined the validity of the Computer Science and Application (CSA) activity monitor during a bout of rehabilitative exercise among older adults with chronic disease. In order to determine convergent validity, 50 participants were monitored during a 30-min walk in Study 1. In order to assess concurrent validity, 10 volunteers wore both ...
Objective Juvenile primary fibromyalgia syndrome (JPFS) is a chronic pain condition associated with significant impairment in physical functioning, but no studies have used newer technologies such as actigraphy to document objective physical activity levels in JPFS. Methods This is the first study to objectively describe physical activity in JPFS patients ...
Objective To investigate the validity of MTI accelerometer as a physical activity (PA) measurement instrument for children with cerebral palsy (CP). Design Participants were classified within Gross Motor Function Classification System I to III and took part in 2 activity sessions: (1) a structured activity protocol with increasing intensities and (2) a free ...
