Abstract

Objectives: Exercise is reported to improve function for people with Ankylosing Spondylitis (AS) but it is not clear if this effect is causal or if patients with milder disease find it easier to exercise. This study examines the effect of exercise and motivation to exercise on function, while contro...

This study examines the effect of exercise and motivation to exercise on function, while controlling for disease severity.Methods: Participants who were members of an existing AS cohort were asked about physical activity, motivation to exercise, function and disease severity. Path analysis on STATA was used to examine the correlation between factors associated with function at time of exercise and with function after 3 months of follow-up.
