Physical therapy and applied behavior analysis are two distinct disciplines that work well together. Physical therapists use hands-on rehabilitation techniques to restore movement and function, while ABA principles can complement physical therapy when behavioral engagement affects treatment outcomes. For PTs who want to deepen their ABA expertise, the BCBA credential is one path worth exploring.
Physical movement touches everything. From jumping and running to picking up a pencil or gripping a fork, our ability to move without pain or restriction is central to the quality of life. Physical therapy exists to restore, maintain, and improve that function — and it covers a wider range of conditions than most people realize.
What makes physical therapy especially interesting in the context of ABA is how much overlap exists between the two fields. Physical therapists observe behavior, respond to patient motivation, and work to shift patterns that interfere with recovery. ABA principles offer a structured framework for doing that more intentionally. The two disciplines don’t just coexist — they can reinforce each other in meaningful clinical ways.
What is a Physical Therapist?
Physical therapists (PTs) are doctoral-trained, and state-licensed healthcare professionals focused on physical rehabilitation, health maintenance, and injury prevention. Some PTs pursue voluntary board certification in specialty areas, but all must hold state licensure to practice.
PTs are autonomous practitioners in all states, and many states allow some form of direct access without a physician referral, though specific rules and any time or visit limitations vary by state.
PTs work with patients across the full lifespan. A typical week might include treating a toddler with a birth injury, an athlete recovering from surgery, and an elderly patient managing arthritis. Their role spans far more than exercise prescription. It includes hands-on therapy, patient education, home program development, and coordination with other healthcare providers.
A medical assessment by a physical therapist might evaluate muscle function, joint flexibility, range of motion, strength, balance, posture, motor function, and respiration. From there, PTs design individualized treatment plans and frequently reassess progress to adjust the approach as needed.
Common PT techniques include manual therapy, therapeutic exercise, ultrasound and electrotherapy, vestibular training, traction, and motor learning strategies. Many plans are carried out in part by physical therapist assistants (PTAs), though the PT retains oversight throughout.
Physical therapists practice in a wide range of settings, including outpatient clinics, hospitals, skilled nursing facilities, schools, home health environments, sports training centers, and occupational settings.
Conditions Physical Therapists Treat
The scope of PT is broad. Here’s a look at some of the major areas:
Pediatrics: PTs work with infants and children on developmental delays, birth injuries, congenital disorders like cerebral palsy or muscular dystrophy, and developmental conditions, including autism.
Cardiopulmonary: Rehabilitation after heart surgery or heart attack, plus ongoing care for patients with COPD, ALS, multiple sclerosis, asthma, and cystic fibrosis.
Musculoskeletal: Sciatica, chronic back pain, arthritis, osteoporosis, spinal stenosis, bulged discs, and rotator cuff tears are among the most common musculoskeletal cases PTs see.
Neurological: Spinal cord injuries, stroke, and traumatic brain injury recovery, Parkinson’s disease, Alzheimer’s, and multiple sclerosis all benefit from physical therapy.
Sports injuries: Concussions, sprains, knee injuries, fractures, shin splints, and ligament damage often require structured PT programs for full recovery.
Post-surgical recovery: Hip, knee, and shoulder replacements, spine surgeries, cancer surgeries, and carpal tunnel repair all commonly include a PT component.
How ABA Fits Into Physical Therapy
ABA has traditionally been associated with autism treatment, but the behavior analysis principles behind it apply across a much wider range of clinical contexts. Physical therapy is one of them.
Here’s the core connection: physical therapists already observe behavior and respond to how patients engage with treatment. ABA principles offer a structured framework for addressing behavioral barriers — fear, avoidance, low motivation — that slow physical progress. When those barriers are present, ABA-informed strategies can help a PT respond more systematically and effectively.
Positive reinforcement is the most direct example. When working with a young child to build muscle tone and strength, a PT might introduce a favorite toy that the child can only reach by completing a specific exercise. The toy serves as both motivation and reward. The task can also be broken into smaller steps, with each step earning a reward — a technique called shaping that’s central to ABA practice.
For adult patients, goal reminders can function as motivational strategies aligned with behavior-analytic principles. Reminding a patient that completing a specific milestone means walking without a walker or returning to a sport can help sustain engagement when progress feels slow.
It’s worth noting that ABA services in medical settings must be delivered within scope-of-practice regulations and applicable state licensure laws. How ABA principles are applied will depend on the PT’s training and the regulatory framework in their state.
How to Become a Physical Therapist
Regardless of specialty area, all physical therapists must complete a doctoral-level program and earn state licensure before practicing.
PT education starts with a Doctor of Physical Therapy (DPT) degree from a program accredited by the Commission on Accreditation in Physical Therapy Education (CAPTE). There are currently around 250 accredited DPT programs in the U.S. Most require a bachelor’s degree for admission, though some offer a 3+3 track that combines undergraduate and professional study.
The DPT is typically three years long and covers biology and anatomy, physiology, exercise physiology, biomechanics, kinesiology, neuroscience, pharmacology, pathology, ethics, clinical reasoning, and evidence-based practice. The final clinical experience runs about 27 weeks.
After graduation, PTs must pass the National Physical Therapist Exam (NPTE) administered through the state where they’re seeking licensure. You can find state-specific licensure requirements here.
Advanced Education and Specialization
After earning the DPT, many physical therapists pursue additional training to deepen their expertise.
Clinical fellowships and residencies are one option. A residency prepares a new PT in a specific area of practice, while a fellowship is geared toward board-certified PTs seeking advanced clinical expertise. The American Board of Physical Therapy Residency and Fellowship Education oversees these programs.
Specialty certification is another path. The American Board of Physical Therapy Specialties (ABPTS) offers voluntary board certification in eight specialty areas: Cardiovascular and Pulmonary, Clinical Electrophysiology, Geriatrics, Neurology, Orthopaedics, Pediatrics, Sports Physical Therapy, and Women’s Health. Candidates need at least 2,000 clinical hours in their chosen specialty (with 25% earned in the last three years) before sitting for the exam.
ABA Certification for Physical Therapists
Physical therapists who want to formalize their ABA training have a path to the Board Certified Behavior Analyst (BCBA) credential, though it requires substantial additional training — and the window is narrowing.
As of 2026, the BACB offers two active pathways. Pathway 1 requires a master’s or doctoral degree from an ABAI-accredited or ABAI-recognized behavior analysis program. That’s the direction the BACB is moving toward for all future applicants. Pathway 2 is the one most relevant to PTs: it allows candidates with a graduate degree in any field — including a DPT or a master’s in physical therapy — to qualify, provided they complete 315 hours of graduate-level behavior-analytic coursework across six required content areas and fulfill supervised fieldwork requirements of 1,500 to 2,000 hours of ABA-specific supervised experience.
That coursework can’t come from PT training. It has to be specifically behavior-analytic content, typically equivalent to about 21 graduate credits. Under the BACB’s Pathway 2 Course Attestation System (which replaced the former Verified Course Sequence system as of January 1, 2026), universities offering this coursework must designate an active BCBA faculty member to review and attest to each student’s compliance.
There’s an important timing reality here: Pathway 2 is being phased out. The BACB has announced it will be eliminated on January 1, 2032. After that date, only graduates of ABAI- or APBA-accredited behavior analysis degree programs will qualify for the BCBA. Physical therapists interested in this credential have a window, but it’s closing. You can review current BCBA requirements directly at BACB.com.
How Much Do Physical Therapists Make?
Physical therapists earn strong salaries, and the latest federal data shows consistent growth in compensation over recent years.
According to May 2024 data from the U.S. Bureau of Labor Statistics, the national median annual wage for physical therapists was $101,020. Here’s how the full pay distribution breaks down:
- 10th percentile: $74,420
- 25th percentile: $83,470
- Median (50th percentile): $101,020
- 75th percentile: $117,190
- 90th percentile: $132,500
Geography plays a big role in PT earnings. The five highest-paying states by mean annual wage as of May 2024 were California ($120,970), Nevada ($113,700), Alaska ($113,190), New Jersey ($109,470), and Illinois ($107,980).
At the metro level, California markets lead nationally. The San Jose-Sunnyvale-Santa Clara area tops the list with a median of $137,250, followed by Vallejo ($136,440), San Francisco-Oakland ($136,200), Santa Rosa-Petaluma ($134,810), and Chico ($131,370).
Work setting also affects earnings significantly. Outpatient care centers paid a median of $122,190, home health services came in at $108,110, hospitals at $105,190, and nursing and residential care facilities at $105,590.
Looking ahead, the BLS projects physical therapist employment to grow 11% from 2024 to 2034 — much faster than the average for all occupations — with roughly 13,200 job openings per year, driven by an aging population and growing demand for rehabilitation services.
Frequently Asked Questions
Can a physical therapist also become a BCBA?
Yes. Physical therapists can currently pursue BCBA certification through the BACB’s Pathway 2, which accepts a graduate degree in any field. They’d need to complete 315 hours of graduate-level behavior-analytic coursework and 1,500 to 2,000 hours of ABA-specific supervised fieldwork, then pass the BCBA exam. This pathway closes January 1, 2032, so anyone considering it should plan with that deadline in mind.
What’s the difference between ABA and physical therapy?
ABA is a science focused on understanding and changing behavior through environmental interventions, most commonly applied in autism treatment and behavioral health. Physical therapy focuses on restoring physical function, movement, and mobility through exercise, manual techniques, and rehabilitation. The two can work together when behavioral barriers like fear, avoidance, or low motivation affect a patient’s engagement with PT treatment.
Where do physical therapists typically work?
Physical therapists work across a wide range of settings. The most common include outpatient PT clinics, hospitals, skilled nursing facilities, home health agencies, schools, sports facilities, and inpatient rehabilitation centers. Setting also affects salary, with outpatient care centers generally paying the highest median wages.
How long does it take to become a physical therapist?
Most physical therapists complete a bachelor’s degree (four years) followed by a Doctor of Physical Therapy program (three years), for a total of seven years of education. After graduation, they must pass the NPTE and meet any state-specific licensure requirements before practicing.
What is the job outlook for physical therapists?
The BLS projects 11% employment growth for physical therapists from 2024 to 2034, much faster than average. An aging population and increased demand for rehabilitation services are the main drivers. The BLS estimates about 13,200 job openings per year over that period.
