More than half of all patients with psoriatic arthritis (PsA) exhibit progressive erosive arthritis, associated with severe functional impairment and psychosocial disability. Biologics have been suggested to be more effective in inducing minimal disease activity" (MDA) than disease-modifying antirheumatic drugs (DMARDs). Behavioral patient education appears to be more effective in encouraging patients to increase their physical activity (PA) levels. The aim of the study was to evaluate the benefits of home-based exercises program on disease activity and quality of life in MDA-PsA patients treated with an anti-tumor necrosis factor (TNF) and DMARD therapy. We observed a self-reported adherence rate to home-based exercise of 76.6% and data showed the impact of the exercise program on self-reported health and mental assessment. A positive relationship between patient and therapist is crucial, influencing the quality of the performance, the emotional support, and increasing motivation in PsA patients.
