BackgroundThe purposes of this study were to (1) describe physical activity of adult manual wheelchair users as measured by wrist actigraphy and two self-report measures, (2) compare exercisers and nonexercisers on measures of physical activity, and (3) examine the relationships between three activity measures.MethodsFifty manual wheelchair users wore an activity monitor and completed a physical activity record for 7 days. At the completion of this period, a questionnaire that included the Physical Activity Scale for Individuals with Physical Disabilities, stage of exercise question, and demographic and health questions was completed.ResultsMean daily hours spent in bed or asleep was 9.1, mean hours of light intensity activity was 12.5, mean hours of moderate intensity activity was 1.3, and mean hours of strenuous activity was 0.33. Thirty-eight percent did not report any strenuous activity, and 56% reported less than the 150 minutes weekly of moderate or strenuous activity required to meet public health guidelines. There was variability in both self-reported and objectively measured physical activity. Regular exercisers were not significantly different from nonexercisers on objective measures of physical activity. Measured physical movement was weakly correlated with recall of physical activity or exercise.ConclusionMany wheelchair users do not meet public health guidelines for physical activity, but they are not a homogeneous group in intensity and frequency of physical activity. Multiple measurement methods can provide insights into the nature, intensity, and duration of physical activity that is more complex due to variations in abilities and ways of moving.
