Truth be told: evidence of wheelchair users' accuracy in reporting their height and weight.

Objectives: To examine whether wheelchair users' self-reports of height and weight differed significantly from direct measurements and whether weight category classifications differed substantially when based on self-reported or measured values.

Design: Single group, cross-sectional analysis. Analyses included paired t tests, chi-square test, analysis of variance, and Bland-Altman agreement analyses.

An exercise trial for wheelchair users: project workout on wheels.

There is growing interest in promoting health for people with disabilities, yet evidence regarding community-based interventions is sparse. This paper describes the design details of a randomized controlled trial (RCT) that will test the effectiveness of a multi-component behaviorally based, intervention to promote exercise adoption (over 6 months) and maintenance (up to one year) among wheelchair users and includes descriptive data on participant characteristics at baseline. Participants were randomly assigned to either a staff-supported intervention group or a self-guided comparison group.
