OSTEOARTHRITIS OF THE KNEE
The impact of low back pain (LBP) on society and health care and its related cost is well established.The World Health Organization defined adherence as “the extent to which a person’s behavior – taking medication, following a diet, and/or executing lifestyle changes, corresponds with agreed recommendations from a health care provider.”To increase patient adherence to HBE recommendations, interventions targeting patient adherence were developed and showed varying levels of effectiveness. For instance, a trial investigating the effects of practitioner communication skills training on patients’ adherence to HBE recommendations in patients with chronic LBP found that adherence declined over time and the intervention appeared to only slow the rate of decline.With the large number of both patient- and therapist-related factors influencing patient adherence, it is likely that adherence varies significantly between individuals and over time. Furthermore, the trajectory of adherence over time during the treatment period is likely to vary among patients with LBP.Although, to date, no studies have examined the presence of common trajectories of adherence to HBE recommendations in patients with LBP, evidence for distinct trajectories of adherence has been found in patients with osteoarthritis of the knee and/or hip, and in older adults with cognitive impairment rehabilitating at home after hip fractures.Therefore, the aim of this study was to investigate the presence and proportion of groups of patients with distinct trajectories of adherence to HBE recommendations among people with LBP and to identify differences in baseline characteristics between groups.
