The Omron HJ-151 and HJ-720ITC pedometers demonstrated validity and reliability at various mounting positions under prescribed and self-paced walking conditions with both healthy and overweight adults.

Relatively little is known about the health and fitness of adults with visual impairments. This article documents the physical activity levels and body-composition profiles of young and middle-aged adults with visual impairments and addresses the concomitant effects of these factors on perceived quality of life.

Objective-To document the influence of age on step activity patterns in children with cerebral palsy (CP) and typically-developing (TD) children. Design-Cross-sectionalSetting-All step activity data were collected in free-living environments.Participants-Children with CP (n=27; 4 -18 years; 22 boys, 5 girls, Gross Motor Function Classification System Levels I and II) and 27 age-and sex-matched TD children were recruited through public advertisements and contacts with local clinicians. CP and TD participants were stratified into younger (< 10 years; n = 14) and older (10-18 years; n = 13) age groups.Intervention-Daily step activity was monitored using a StepWatch Activity Monitor that was individually programmed to account for the gait characteristics of each participant.Step activity data were collected in 1-min epochs during waking hours on three weekdays and one weekend day. Stored data were analyzed to yield average values of daily step activity, percentage of inactive time (0 steps) over the entire day, and percentage of total daily active time spent in low step activity (1-15 steps/min), medium step activity (16-40 steps/min), and high step activity (> 40 steps/min).Main Outcome Measures-Daily step activity, percentage of inactive time, and percentage of active time spent in low-, moderate-, and high-intensity step activity.Results-A significant (p < .05) interaction was observed between age (younger, older) and condition (CP, TD) for daily step activity, percentage of inactive time, and percentage of active time spent in low-and high-intensity step activity. The main effect of age was significant for each physical activity measure except for relative high-intensity step activity and the main effect of condition was significant for all physical activity measures. Followup analyses (p < .025) revealed that older children with CP took fewer daily steps and displayed higher relative levels of inactivity © 2010 The American Congress of Rehabilitation Medicine.

As a first step toward the development of adapted physical activity (PA) programs for adults with visual impairment (VI), the purpose of this study was to determine the time frame needed to reliably estimate weekly PA in adults with VI. Thirty-three adults with VI completed 7 days of pedometer-based PA assessment. Generalizability theory analyses were conducted to quantify sources of variance within the PA estimate and determine the appropriate number of days of PA monitoring needed for the total sample and for participants with mild-to-moderate and severe VI. A single-facet, crossed design was employed including participants and days. Participants and days correspondingly accounted for 33–55% and 0–3% of the total variance in PA. While a reliable account of PA was obtained for the total sample over a 6-day period, shorter (4-day) and longer (9-day) periods were required for persons with mild-to-moderate and severe VI, respectively.

In unfamiliar and familiar walking conditions, the Centrios pedometer accurately monitors step-based activity in adults with VI when mounted at the hip opposite the user's MA.
