In summary

The short answer: occupational therapy (OT) and physical therapy (PT) are sister rehabilitation professions that often treat the same people, but they aim at different targets. Occupational therapy is concerned with how a person carries out the everyday activities that matter to them (self-care, work, learning, play, caregiving, community life) and works to build skills, adapt tasks or modify the environment so participation becomes possible. Physical therapy is concerned with movement and physical function, and with the body's capacity to recover and adapt after injury, disease, disability or aging. In the vocabulary of the WHO International Classification of Functioning, Disability and Health, OT research concentrates on the activity and participation levels and on person-environment fit, while PT research leans toward body structures, functions and movement. The two overlap heavily in practice. They share outcome instruments (the Berg Balance Scale and the Timed Up and Go test appear in both literatures), share trials and funders, and both face the same rehabilitation-trial problems: limited blinding, hard-to-build comparators, complex individualized interventions and small, heterogeneous samples. A person recovering from stroke or a hip injury may well see both. Verdict: if the main difficulty is doing a daily task (dressing, cooking, writing, returning to work, managing a home safely), occupational therapy is the closer fit. If the main difficulty is moving (walking, balance, strength, range of motion, pain with movement), physical therapy is the closer fit. Many conditions need both, and the contrasts in the table are tendencies, not rules. This page is an educational comparison of two professions and their research fields, not clinical advice; a licensed clinician decides which service suits a particular person.

How do Occupational therapy, Physical therapy compare side by side?

The table below compares Occupational therapy, Physical therapy across 12 procurement-relevant dimensions, from core definition through overlap and when to use which.

Side-by-side comparison

Dimension	Occupational therapy	Physical therapy
Core definition	A health profession and research field concerned with how people carry out meaningful everyday activities ("occupations") and how illness, injury, disability or environment interferes with that participation. Its sister research tradition is occupational science.	A health profession and clinical discipline concerned with movement, physical function and the body's capacity to recover and adapt. Called physiotherapy in much of the world; the research literature uses both terms.
Central focus	Participation in daily life: self-care, work, learning, play, caregiving and community roles, and the fit between the person, the task and the environment.	Movement and physical function: mobility, strength, balance, range of motion, and how the musculoskeletal and nervous systems adapt to training after impairment.
ICF level emphasized	Mainly activities and participation, plus environmental factors.	Mainly body structures and functions, and the activities that depend on them.
Typical settings	Hospitals and rehabilitation units, outpatient clinics, schools and early-intervention programs, mental health and community services, workplaces and people's homes.	Hospitals and rehabilitation units, outpatient clinics, sports and performance settings, cardiopulmonary and geriatric programs, and people's homes.
Common assessment tools	Performance-based observation of a task such as meal preparation, clinician-rated independence scales (Barthel Index, Functional Independence Measure), patient-reported measures of participation and satisfaction with performance, and caregiver or proxy reports for young children.	Performance-based tests (walking speed and endurance, strength testing), clinician-rated independence scales (Barthel Index, Functional Independence Measure), patient-reported pain and function measures, and gait data from wearables or motion capture.
Shared instruments	Berg Balance Scale and Timed Up and Go test when mobility and falls are the focus.	Berg Balance Scale and Timed Up and Go test, which are core performance tests in the PT literature.
Interventions (general terms)	Building skills, adapting tasks, adaptive equipment and assistive technology, home and workplace modification, routine and role rebuilding. Often behavioral, skill-based or environmental rather than pharmacological.	Exercise, manual and movement-retraining approaches, load management, balance and gait training, graded activity and education for persistent pain. Also often behavioral or skill-based rather than pharmacological.
Research questions	Which interventions help a child participate in school; how a person recovering from stroke resumes daily routines; how home and workplace changes affect independence; how to measure participation in a way that matters to the person.	Which exercise, manual or movement-retraining interventions improve function for a given condition; how much is needed and for how long; which patients benefit most; how tissues and the nervous system adapt.
Regulation and accreditation (general terms)	Practice in the United States requires an accredited entry-level program, a national certification examination and state licensure, with equivalent registration systems elsewhere. Assistants follow a separate, shorter pathway.	Practice in the United States requires graduating from an accredited entry-level program and meeting state licensure requirements; the profession has its own accrediting body and national association, with national federations internationally.
Professional bodies and journals	American Occupational Therapy Association (AOTA; American Journal of Occupational Therapy) and the separate American Occupational Therapy Foundation (AOTF; Occupational Therapy Journal of Research).	American Physical Therapy Association (APTA; the journal Physical Therapy) and, internationally, World Physiotherapy.
Funders	NIH (including NICHD's National Center for Medical Rehabilitation Research), NIDILRR at the Administration for Community Living, AOTF grant programs, VA, DoD, NSF for engineering work, foundations and industry. NIDILRR's disability, independence and community-participation themes sit close to OT.	The same federal channels: NIH (NCMRR and other institutes), NIDILRR, VA, DoD, NSF for engineering-oriented work, foundations, professional association foundations and industry for devices.
Overlap and when to use which	Closer fit when the difficulty is performing daily tasks, returning to work or school, or making a home or workplace workable. Frequently paired with PT after stroke, brain or spinal cord injury, hand and upper-extremity injury, and in older adults.	Closer fit when the difficulty is moving: walking, balance, strength, joint or spine problems, or return to activity after injury or surgery. Frequently paired with OT after stroke, in geriatric rehabilitation and in pediatric development.

Common questions

Common questions about Occupational therapy vs Physical therapy

What is the main difference between occupational therapy and physical therapy?

Their targets differ. Occupational therapy focuses on participation in the everyday activities that matter to a person (self-care, work, learning, play, caregiving) and on adapting tasks or environments. Physical therapy focuses on movement and physical function, such as mobility, strength and balance. The two professions often treat the same people and share research methods and outcome instruments.

Do occupational therapists and physical therapists treat the same conditions?

Often, yes. Stroke, brain and spinal cord injury, falls and aging, pediatric developmental conditions and many orthopedic problems appear in both literatures. What differs is the question each profession asks: how can this person do their daily activities, versus how can this person move and function physically. Which service suits an individual is a decision for a licensed clinician.

Is physiotherapy the same as physical therapy?

Yes. In the United States the profession is called physical therapy; in much of the rest of the world it is physiotherapy. They describe the same discipline, and a literature search that uses only one term will miss part of the evidence.

Which one focuses on daily living skills?

Occupational therapy. Its concept of occupation covers dressing, cooking, driving, writing, parenting, working and community life, and its assessments and interventions are built around performing those activities, including through adaptive equipment and environmental modification.

Do the two professions use the same outcome measures?

Partly. Both use clinician-rated independence scales such as the Barthel Index and the Functional Independence Measure, patient-reported outcome measures, and performance tests such as the Berg Balance Scale and Timed Up and Go when mobility and falls are the focus. OT additionally uses task-performance observation and individualized goal-rating measures; PT additionally uses strength, walking and laboratory movement measures.

How are the two researched and funded?

Both sit inside rehabilitation science and use the full range of health designs: randomized and pragmatic trials, observational studies, single-case designs, qualitative and mixed methods, and systematic reviews. Both face limited blinding and hard-to-build comparators. US federal funding comes from NIH (including the National Center for Medical Rehabilitation Research at NICHD) and NIDILRR, among others. Check each agency for current programs and deadlines.

Can a person need both occupational and physical therapy?

Yes, and it is common, for example after a stroke or a serious injury, where one profession works on movement and the other on resuming daily routines and roles. This page is educational and not clinical advice; a clinician determines what a particular person needs.
