Occupational therapy is a science-driven profession that applies the most up-to-date research to service delivery. Evidence supports the effectiveness of adding an occupational therapy practitioner to your patients’ or clients’ treatment plan. According to systematic reviews from AOTA’s Evidence-Based Practice Occupational Therapy Practice Guidelines, evidence shows that the following occupational therapy interventions improve client outcomes. These interventions are used as part of a broad approach that considers the patient’s performance skills (motor, process, social interaction); activity demands; performance patterns (habits, routines, rituals, roles); and contexts and environments.
