Physical therapists lead the process in development, implementation, and coordination of the physical therapy program. Screening, evaluation, therapeutic intervention, transition and exit planning is provided for clients identified with or suspected of having disabilities that interfere with their ability to perform daily life activities or participate in necessary or desired occupations. Professional judgment and clinical knowledge are used to develop individualized programming based on physical performance deficits. The physical therapist regularly collaborates with other disciplines and services at departmental and system levels, and is expected to independently review outcomes and modify intervention programs as needed. Clinical reasoning and professional judgment are essential to ensuring the safety of clients and protecting liability of the company and the therapist. Errors may result in serious harm to clients. Direct supervision may be exercised over support personnel, such as physical therapy assistants and direct care staff.
