OBJECTIVE: To evaluate the impact of physical rehabilitation interventions, supplemented with one or more adherence-enhancing components, on outcomes among adults with hip or knee osteoarthritis or chronic lower back pain. DESIGN: Primary literature search from inception of each database to July 27, 2021, guided by relevant search terms and keywords to search titles and abstracts. All articles meeting eligibility criteria were included for data abstraction. DATA SOURCES: MEDLINE, CINAHL Complete, and Embase. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomized and nonrandomized trials evaluating adherence-focused intervention components conducted in addition to an index usual care or usual care-like physical rehabilitation program among adults with hip or knee osteoarthritis or chronic low back pain. Eligible studies included a comparator group of the same index physical rehabilitation intervention without the adjunctive adherence components. Included studies measured outcomes at least 3 months after the rehabilitation course. RESULTS: Of the 10 studies meeting inclusion criteria, 6 interventions were delivered concurrent to an index rehabilitation program and 4 were delivered sequentially. Of the 3 studies that reported a positive effect on long-term adherence, only 1 was a low risk of bias study. There is very limited evidence of a beneficial treatment effect of adjunct adherence interventions on long-term physical function, self-efficacy, or adverse events. CONCLUSION: We found inadequate evidence evaluating adherence-enhancing interventions for the specific promotion of long-term adherence to home rehabilitation programs. Future studies should consider testing interventions specifically built to target behavioral maintenance of home rehabilitation programs.
