摘要

Sedentary time negatively influences health and is a risk factor for chronic low back pain (CLBP). Emerging evidence suggests breaking up prolonged sedentary behaviors may improve CLBP. This pilot trial examined the influence of decreasing sedentary behaviors on pain, mood, and quality of life in CLBP. Forty adults with CLBP and elevated depressive symptoms were randomized to wear an activity tracker with an idle alert along with receiving health coaching based on Motivational Interviewing and Habit Theory (INT) or a wait-list control condition (WLC) for eight weeks with a 12-week follow-up. Actigraphy-assessed time in total and prolonged sedentary behaviors, pain, depressed mood, quality of life, Patient Global Impression of Change (PGIC), and habits surrounding sedentary behavior were assessed at pre-intervention, post-intervention, and at follow-up. Repeated measures ANOVAs were used to examine changes in outcomes. Results demonstrated that INT reduced time spent in prolonged sedentary bouts by an average of ~ 53 min/day (95% CI − 111.8 to 5.4), compared to WLC who decreased by an average of less than 1 min/day, based on wearable activity monitor data (difference between groups, 52.9 min/day, 95% CI − 27.2 to 133.1). There were no significant group-by-time interactions for pain nor depressed mood. Significant improvements for INT over WLC were demonstrated with moderate-to-large effects in Quality of life (physical health, g = 0.95, and bodily pain, g = 0.70), PGIC (g = 1.14), and sedentary behavior habit automaticity (g = 0.71). These results demonstrate potentially meaningful improvements in patient quality of life and physical activity after an intervention that decreased prolonged sedentary time in those with CLBP, although further study in larger scale efficacy trials is warranted. Perspective: This article presents the findings from a pilot trial examining whether breaking up prolonged bouts of sedentary time improves symptoms and quality of life in chronic low back pain. Results can be used to determine whether this strategy is worthy of further investigation.
