About Occupational Therapy

Occupational therapy is a healthcare profession that focuses on helping people participate in the meaningful activities they need and want to do. The typical occupational therapy client is one who has experienced a change in their ability to fully participate in these chosen activities, most often due to a change in health status. Occupational therapy is unique in that it uses a holistic approach to look not only at the reasons a client’s participation in activities has been impacted, but also at the client’s roles and environment and includes wellness promotion, rehabilitation, and habilitation. The occupational therapy professional assists the client to regain function or adapt to changes by assessing and addressing the physical, cognitive, psychosocial, sensory, and environmental aspects of recovery.

Role of an OTR and COTA

In the profession of occupational therapy, the occupational therapist registered (OTR®) and certified occupational therapy assistant (COTA®) work collaboratively. Both the OTR and COTA are certified health professionals who have completed occupational therapy education and passed a national certification examination. The OTR is responsible for evaluating the client, planning of therapeutic interventions, and completing discharge documents. The OTR also provides clinical supervision of the COTA. The COTA implements the therapeutic interventions, documents these interventions, and provides feedback to the OTR on the client’s progress during treatment.
