The intervention group received usual care with integrated support via a smartphone app. A total of 208 patients were recruited from 58 primary care physical therapist practices. Baseline data included patient characteristics, physical functioning, pain intensity, physical activity, fear avoidance, pain catastrophizing, self-efficacy, self-management ability, and health-related quality of life. The Exercise Adherence Scale (score range\u2009=\u20090\u2013100) was used to measure adherence during each treatment session. Latent class growth analysis was used to estimate trajectories of adherence.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Adherence data were available from 173 out of 208 patients (83%).

Three trajectory classes were identified: \u201cdeclining adherence\u201d (12%), \u201cstable adherence\u201d (45%), and \u201cincreasing adherence\u201d (43%).
