RELATIONSHIPS BETWEEN PHYSICAL ACTIVITY PROFILES AND PAIN IN THE MORPH-II STUDY

abstract
This secondary analysis of a pilot randomized trial on older adults with chronic pain investigates the longitudinal relationships between physical activity (PA) volume, patterning, and pain symptoms. METHODS: Older adults with chronic pain were randomly assigned to a 12-week remote group-mediated PA intervention or a minimal contact control. Participants (N=37; 68.81±8.00 years) wore an activity monitor continuously and completed PROMIS pain intensity and interference scales at week 0 and week 12. RESULTS: Mixed models predicting pain interference revealed a significant steps x time interaction whereby increases in stepping was associated with less interference. There was a significant steps x bout length interaction whereby engaging in greater steps in shorter bouts was associated with less interference. There was an interaction between steps and variance min/hour of PA whereby those engaging in higher steps with less variability demonstrated greatest interference. Models predicting steps revealed a significant time x group x baseline interference interaction, such that intervention participants with low interference were likely to move less over time, whereas those with high interference or who were in control tended increase over the study period. CONCLUSIONS: Additional research should investigate the impact on pain; specifically targeting high levels of activity in shorter bouts.
