Physiatrist vs. Psychiatrist: What Are the Differences?

A physiatrist treats the body: spinal cord injuries, stroke recovery, chronic pain, and anything that limits movement, using therapy, injections, and rehabilitation plans rather than surgery. A psychiatrist treats the mind: depression, anxiety, bipolar disorder, and other mental illness, mostly with medication and psychotherapy referrals. Physical medicine and rehabilitation (PM&R) is the formal name for what a physiatrist does, and the similar-sounding job titles are the main reason people mix the 2 up.

What does a physiatrist do?

Physiatrists diagnose and treat conditions that limit how the body moves or functions, without surgery. Many of their patients are recovering from a major medical event, such as a stroke, spinal cord injury, or amputation, or managing a chronic condition like arthritis or nerve pain.

Typical duties include:

• Examining muscle strength, reflexes, and range of motion to find the source of pain or weakness
• Building rehabilitation plans with physical therapists, occupational therapists, and speech therapists
• Performing spine and joint injections for pain
• Managing spasticity in patients with cerebral palsy, stroke, or spinal cord injury, including Botox and baclofen pump management
• Prescribing and fitting braces, prosthetics, and wheelchairs
• Directing care on an inpatient rehabilitation unit for patients relearning daily activities
• Treating sports injuries and overuse conditions in an outpatient setting

Work setting and a typical day

Physiatrists work in inpatient rehabilitation hospitals, outpatient spine and musculoskeletal clinics, and sports medicine practices. An inpatient physiatrist rounds on a rehab unit each morning, adjusting therapy plans and medications for patients recovering from strokes or major surgery, then may see outpatient consults in the afternoon. An outpatient physiatrist runs a clinic focused on back pain, joint pain, or concussion management, often performing injections between visits.

Career path into PM&R

1. A 4-year bachelor's degree with premed coursework
2. 4 years of medical school (MD or DO) and the USMLE or COMLEX licensing exams
3. A 1-year internship (transitional year, or a year of internal medicine, family medicine, or surgery)
4. A 3-year PM&R residency
5. The ABPMR Part I Examination, a computer-based exam
6. The ABPMR Part II Examination, an oral exam
7. An optional 1-year fellowship in a subspecialty such as sports medicine, pain medicine, spinal cord injury medicine, or brain injury medicine

What does a psychiatrist do?

Psychiatrists diagnose and treat mental illness, using a combination of medication management, diagnostic evaluation, and coordination with therapists and other providers.

Typical duties include:

• Conducting diagnostic interviews to evaluate mood, thought patterns, and behavior
• Prescribing and adjusting psychiatric medications such as antidepressants, mood stabilizers, and antipsychotics
• Managing patients through medication changes and monitoring for side effects
• Coordinating with psychologists and therapists who provide ongoing talk therapy
• Evaluating patients in crisis for safety, including suicide risk
• Admitting and managing patients on an inpatient psychiatric unit
• Providing consultation to other physicians on patients with psychiatric symptoms complicating a medical condition

Work setting and a typical day

Most psychiatrists work in outpatient clinics, seeing patients in 20 to 30-minute follow-up visits and longer initial evaluations. Others work in hospitals, covering inpatient psychiatric units or providing consultation-liaison services for medical and surgical patients experiencing psychiatric symptoms. Emergency psychiatrists evaluate patients in crisis in the emergency department.

Career path into psychiatry

1. A 4-year bachelor's degree with premed coursework
2. 4 years of medical school (MD or DO) and the USMLE or COMLEX licensing exams
3. A 4-year psychiatry residency; the first year includes at least 4 months of internal medicine, family medicine, or pediatrics (neurology rotations don't count toward those 4 months)
4. Three clinical skills evaluations completed during residency
5. The ABPN Psychiatry Certification Examination
6. An optional 1 to 2-year fellowship in a subspecialty such as child and adolescent psychiatry, addiction psychiatry, geriatric psychiatry, or forensic psychiatry

Key differences

What each one treats

A physiatrist treats the nervous and musculoskeletal systems: nerve and spine problems, muscle weakness, and physical function after an injury or illness. A psychiatrist treats mental illness: mood disorders, psychotic disorders, anxiety, and behavioral conditions. Neither operates, and neither is a therapist who runs weekly talk-therapy sessions, though both refer to specialists who do (physical therapists for physiatry, psychologists and counselors for psychiatry).

Education and training

Stage	Physiatrist	Psychiatrist
College	4 years	4 years
Medical school	4 years	4 years
Residency	1 intern year + 3 years, PM&R	4 years, psychiatry (intern year included)
Fellowship	Optional, usually 1 year	Optional, usually 1 to 2 years
Total after medical school	4 years	4 years
Certifying board	ABPMR	ABPN
Certification exam format	Part I (computer-based) and Part II (oral)	Single certification exam, after 3 clinical skills evaluations during residency

Both residencies run 4 years total after medical school, but physiatry's first year is typically a separate internship year (often at a different hospital), while psychiatry residencies are built as 1 continuous 4-year program with medical rotations folded into the first year.

Pay

BLS gives psychiatrists their own line in the Occupational Outlook Handbook: a median of $281,870 in May 2025. Physiatrists don't get a specific listing; BLS groups PM&R physicians into "physicians, all other," which had a median of $265,930 in May 2025. That's a real but modest gap, and it says more about how BLS categorizes physician specialties than about which job is more in demand.

Job outlook

BLS projects 4% employment growth for physicians and surgeons overall from 2025 to 2035, with about 22,100 openings a year. The Handbook doesn't publish separate projections for physiatrists or psychiatrists, though it notes rising mental health treatment needs and an aging population as broad drivers of physician demand.

Work environment

Physiatry involves more hands-on physical exam and procedures (injections, spasticity management) and more coordination with physical and occupational therapists. Psychiatry involves more time in conversation, diagnostic interviewing, and medication management, with less physical contact with patients.

Where the roles overlap

• Pain medicine is a shared fellowship path. Physicians can become board certified in pain medicine through the ABPMR, the ABPN, or anesthesiology, and physiatrists and psychiatrists both treat chronic pain from different angles.
• Traumatic brain injury care often needs both. A physiatrist manages physical recovery and cognitive rehabilitation, while a psychiatrist manages mood changes, depression, or personality changes that can follow a brain injury.
• Both specialties work on multidisciplinary teams, coordinating with therapists, social workers, and case managers rather than working alone.
• Patients recovering from major trauma, such as a spinal cord injury, often see both: a physiatrist for physical rehabilitation and a psychiatrist for depression or adjustment difficulties that come with a major disability.

Which one fits you

PM&R may fit if you:

• Like physical exam findings and want to see measurable functional improvement over time
• Enjoy working on a team with physical, occupational, and speech therapists
• Want a mix of inpatient rehab and outpatient procedure-based clinic work
• Are drawn to sports medicine, spine care, or brain and spinal cord injury recovery

Psychiatry may fit if you:

• Prefer diagnosing and treating through conversation and psychiatric medication rather than physical exam
• Want to build long-term relationships with patients managing chronic mental illness
• Are comfortable evaluating patients in crisis
• Are interested in a subspecialty such as child psychiatry, addiction medicine, or forensic psychiatry

If you're a medical student weighing the two, the confusion between the names is common enough that it's worth clarifying with rotations: shadow a physiatrist in a rehab unit and a psychiatrist in an outpatient clinic or on a consult service, since the day-to-day work looks nothing alike despite how similar the job titles sound. If you're comparing other physician career paths, see oncologist vs. radiologist and endocrinologist vs. urologist.

FAQ

Is a physiatrist a psychiatrist?

No. The names sound alike, but physiatrists treat physical conditions affecting movement and function (PM&R), while psychiatrists treat mental illness. They train through separate residencies and separate boards, the ABPMR and the ABPN.

Do physiatrists prescribe medication?

Yes, but mostly for pain, muscle spasticity, and related conditions, such as muscle relaxants, nerve pain medication, and Botox injections for spasticity. They don't typically prescribe psychiatric medications like antidepressants or antipsychotics.

Which pays more, a physiatrist or a psychiatrist?

BLS gives psychiatrists a specific median of $281,870 in May 2025. Physiatrists fall under the broader "physicians, all other" category at $265,930. The gap is real in BLS data, though individual pay depends heavily on practice setting and procedure volume for physiatrists.

Can a psychiatrist treat chronic pain?

Some can, usually after an additional pain medicine fellowship through the ABPN. More often, chronic pain management is split between physiatrists, anesthesiologists, and pain medicine specialists, with psychiatrists involved when pain overlaps with depression, anxiety, or substance use.
