Physical Therapist Assistants implement therapeutic interventions (such as exercises) that are part of the plan of care developed by a Physical Therapist. These interventions are designed to help patients who have had surgical procedures or experienced an injury and those with medical conditions such as joint, neurological, pulmonary, or cardiac disease. Job responsibilities for Physical Therapist Assistants typically include documentation of interventions and communicating the patient’s progress to the Physical Therapist. The American Physical Therapy Association offers Advance Proficiency Pathways, which helps Physical Therapist Assistants build their skills in a specialty. The average annual salary for Physical Therapist Assistants in the United States is more than $60,000.
