Associations between patterns of physical activity, pain intensity, and interference among older adults with chronic pain: a secondary analysis of two randomized controlled trials

“…Outside of weekly hour-long group sessions, participants engaged with a Companion App mHealth toolset that was developed by one member of the research team (JF) across four randomized trials (Fanning et al, 2017;Fanning et al, 2020;Fanning et al, 2022a;Fanning et al, 2022b). This toolset, which integrated data in real time from participants' Fitbit Inspire activity monitors and BodyTrace scales, fulfilled three important behavioral support roles: 1) it allowed for ongoing communication via asynchronous chat between group members between meetings; 2) it provided objective visual and numeric feedback on the amount and patterning of PA via real-time Fitbit data streamed into the app, facilitating better awareness of activity patterns and providing a platform for pattern-based goal setting; and 3) it supported the development of self-efficacy by highlighting goal successes via badges; participants were trained to use these badges as cues to savor their progression.…”

“…Herein we present an analysis of PA behavior assessed objectively using ActivPAL accelerometers among older adults with chronic pain. Participants were involved in two distinct randomized controlled pilot studies: the 12-week Mobile Intervention to Reduce Pain and improve Health (MORPH) and MORPH-II, (Fanning et al, 2020;Fanning et al, 2022a), which was a similar intervention with refinements based on knowledge gleaned in MORPH.…”

“…Laboratory data suggest that greater time spent in moderate-to-vigorous intensity PA (MVPA) is a strong predictor of pain facilitation (i.e., greater MVPA is associated with less temporal summation of pain), while less sedentary time and more light intensity physical activity (LPA) are associated with greater pain inhibitory capacity (Naugle et al, 2017). It is notable that sedentary time and LPA have a strong inverse relationship with one another, are driven by habit, and occur in higher volumes across the day relative to MVPA (Owen et al, 2010;Dunstan et al, 2012;Fanning et al, 2022a). Thus, it is logical that these PA behaviors yield different effects on various measures of pain.…”
