Occupational rehabilitation is a multidisciplinary field of study and practice focused on the process of enabling individuals who have experienced injury or illness to return to and maintain participation in work. As an academic concept, it investigates the complex interplay of biopsychosocial, environmental, and occupational factors influencing work capacity and successful work reintegration, the efficacy of interventions designed to restore function and facilitate return-to-work, and the broader health and socio-economic outcomes associated with these processes. Its significance lies in mitigating the personal and societal burdens of work disability, promoting recovery, and optimizing workforce participation.
