What Is a Physical Therapist Assistant?

When you think about healthcare, you probably picture doctors, nurses, or hospitals. Another role you might not see right away is a Physical Therapist Assistant (PTA). PTAs typically work with a licensed physical therapist to provide physical therapy services, helping patients perform therapeutic exercises, complete functional activities, and regain mobility. PTAs may also assist in monitoring patient progress as part of a treatment plan.¹

What Does a Physical Therapist Assistant Do?

Physical Therapist Assistants (PTAs) work under the direction and supervision of a licensed physical therapist to support patients recovering from injuries, illnesses, or other health conditions. They may help patients work to restore function, relieve pain, and manage daily functional activities, following the treatment plan outlined by a physical therapist. PTAs may also provide guidance to patients and families on exercises or routines to continue outside of therapy sessions.¹

Where Do Physical Therapist Assistants Work?

According to the Bureau of Labor Statistics, Physical Therapist Assistants (PTAs) work under the supervision of licensed physical therapists in a variety of healthcare settings, like physician offices, hospitals, home healthcare, skilled nursing facilities, and private facilities.²

PTA Skills and Core Competencies

In specialized settings like acute care, physical therapist assistants may work under the supervision of a licensed physical therapist to deliver interventions for patients with medically complex or compromised conditions. In these settings, PTAs may need to quickly adapt to changing patient needs and could be involved in complex healthcare interventions while maintaining professional behaviors, making their role both specialized and important within the rehabilitation team.³

Specific work experience and/or certifications may be required for a Physical Therapist Assistant (PTA) to work in the area of acute care. It is important to check the requirements needed to work in acute care.

Entry-level PTAs in acute care may begin implementing components of a physical therapy plan of care (POC), under supervision, as they gain experience in a clinical setting. This might include applying interventions across a wide range of diagnoses and age groups, depending on patient needs, to help support safe and consistent care during recovery.³

Collaboration is often key in acute care and other practice settings. PTAs may work alongside physical therapists, physical therapist aides, and other healthcare professionals to monitor patient progress and contribute to overall patient care outcomes. Their involvement could help support the overall patient care plan.³

Specialties Physical Therapist Assistants May Work With

Physical Therapist Assistants (PTAs) often have the opportunity to assist in a variety of specialties, supporting patients with diverse health-related conditions. While PTAs always work under the supervision of licensed physical therapists, exposure to different specialties may broaden their experience and understanding of healthcare.⁴

Some of the common specialty areas may include:⁴

• Pediatrics: Working with infants, children, and youth to support development, manage congenital or acquired conditions, and promote healthy movement.
• Women’s Health: Assisting in care related to pregnancy, post-partum recovery, incontinence, and musculoskeletal conditions affecting women.
• Geriatrics: Supporting older adults with mobility, balance, strength, and activities of daily living, often in outpatient clinics, nursing facilities, or home care.
• Clinical Electrophysiology: Assisting in the use of therapeutic electrical stimulation and other biophysical agents to relieve pain and promote healing.
• Cardiovascular and Pulmonary: Helping patients improve endurance, breathing, and overall function after cardiac or pulmonary events.
• Neurology: Supporting individuals recovering from stroke, spinal cord injuries, or neurological diseases with movement, coordination, and functional rehabilitation.
• Orthopedics: Assisting patients with injuries or surgeries affecting bones, joints, muscles, or ligaments to restore mobility and strength.
• Oncology: Helping patients manage side effects of cancer treatment, improve strength and function, and maintain quality of life during and after therapy.

Specific work experience and/or certifications may be required for Physical Therapist Assistants (PTAs) to work in specialized areas. Please consult with employers regarding the requirements to work in Pediatrics, Women’s Health, Geriatrics, Clinical Electrophysiology, Cardiovascular and Pulmonary, Neurology, Orthopedics, and Oncology.

Exploring different specialties can help PTAs understand clinical education opportunities and the range of health conditions they may encounter. While not all PTAs work in every specialty, awareness of these areas can inform career interests and professional development in various practice settings.⁴

The Evolving Role of Physical Therapist Assistants

Physical Therapist Assistants (PTAs) are members of the rehabilitation team and may perform hands-on patient care activities under the supervision of a licensed physical therapist. Their contributions allow therapy programs to be delivered across a variety of clinical settings.⁵

At the same time, some challenges remain in the profession. Career paths may vary depending on setting and experience. Educators and clinicians have noted that expanding physical therapy education and training pathways through PTA programs could help PTAs meet the changing demands of healthcare and better support patient needs.⁵

These trends highlight the important role PTAs play today and the potential for the profession to continue evolving, which may present professional development opportunities for individuals interested in working as a physical therapist assistant.⁵
