SAFE
The core of the job is physically guiding bodies — manual therapy, gait training, transfers, therapeutic exercise, modality application — with a patient who is in pain, frightened, or deconditioned, and none of that digitizes. PTAs are licensed or certified in nearly every state and work under a PT's plan of care, so a credentialed human must deliver and document the treatment. The automatable slice is real but thin: progress note drafting, exercise-program handouts, insurance documentation, and scheduling.
Dipped in 2020, then grew past where it started.
Median pay $58,790 → $68,380 -7.0% in real terms
This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.
So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.

Hard to automate, and growing
The work resists current AI and the BLS projects +22% more of these jobs by 2034. Note that safe does not mean well paid — several of the fastest-growing resistant occupations are among the lowest paid on the register.
Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.

Holding it up: embodiment . Weakest point: liability shield .
Tasks largely resist digitisation Manual muscle testing, hands-on joint mobilization, spotting a post-op TKA patient through parallel bars, and cueing a hemiplegic patient's weight shift all require real-time tactile feedback and body-to-body contact, leaving only note templating and HEP printouts on the automatable side — which is why this sits at 16 rather than the low teens of jobs with heavy screen-based charting loads.
Hands-on in uncontrolled environments A PTA spends the shift in gait belts, transferring patients from wheelchair to mat table, applying ultrasound and e-stim to skin, kneeling on clinic floors and navigating cluttered home-health bedrooms and SNF hallways — uncontrolled, unpredictable environments where the patient may buckle mid-step, and the only points off 20 are for the documentation hours.
Licensed human required and personally liable Licensure or certification is mandated in nearly all states with continuing-education and jurisprudence requirements, and a PTA can lose that license for treating outside the plan of care — but the evaluation, diagnosis, POC, and discharge decision legally belong to the supervising PT, which caps this below the 17-20 range of independently licensed practitioners.
Exists to be accountable for ambiguous calls Within a session the PTA decides whether to progress resistance, hold back on a patient whose knee is hot and swollen, stop for a blood-pressure or dizziness red flag, and escalate to the PT — real unsupervised calls with patient-safety consequences.
The verdict above describes this occupation as a whole. Almost nobody does the typical version of a job — tick what's actually in your week and see how your own mix sits.
Your task mix speaks to task resistance (16/20 here) — how much of the day's work current AI already does. That is the dimension the boxes above are about.
It cannot move the other three. Liability shield (13/20) is whether the law requires a licensed human to sign. Trust premium (16/20) is whether buyers specifically pay for a person. Judgment and accountability (15/20) is whether the role exists to own consequential calls. Those are facts about the occupation's standing, not about which tasks are in your week — a paralegal who does only trial exhibits still holds no licence. Together they are 44 of this occupation's 79 points (56%).
Embodiment (19/20) is also a property of the work rather than the worker, but we don't tag individual tasks as physical or not, so the picker can't tell you anything about it. That's a limit of this tool, not a claim.
Did we get the list right? Tell us what's missing — the tasks are written from the outside, and you're reading this from the inside.
The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 88/100, still SAFE.
Genuine two-tier job: if AI documentation (Netsmart/WebPT ambient note tools), HEP handout generation, and prior-auth paperwork are fully absorbed, the residual day is nearly all hands-on progression, cueing, and patient-response reading. Task-mix shift alone raises resistance without any new law.
CMS therapy billing rules already require that services be furnished by a licensed therapist or a PTA under supervision; a tightening of the Medicare Part B supervision standard (e.g. reverting the private-practice requirement to direct rather than general supervision, or explicitly barring billing for any exercise session delivered by an app or unlicensed aide without an on-site PTA) would push this up. Also state practice-act amendments defining 'therapeutic exercise delivery' as a licensed act that telehealth/remote-monitoring vendors cannot substitute.
If state boards and APTA scope guidance formalize the PTA's duty to halt or modify treatment on adverse response and to escalate to the PT — with documented board discipline for failure to do so — the role's ownership of in-session safety calls (post-op precautions, orthostatic events, red-flag referral) becomes an accountable one rather than a delegated task.
Narrow route only: if payers or employers begin marketing remote-monitored app-based rehab (Hinge Health, Sword Health) as the default and outcomes for post-surgical or elderly patients diverge, orthopedic surgeons' referral preferences for in-person hands-on treatment become an explicit purchased preference. Weak lever — most PTA demand is payer-directed, not patient-chosen.
The limit. Already near ceiling on embodiment (19) and task_resistance (16); realistic headroom is a few points in liability_shield and judgment_accountability. The real downside risk is not automation but substitution by lower-cost app-based rehab benefits and by unlicensed aides where supervision rules loosen — a scope/reimbursement fight, not a capability one.

We have no reported case of a named organisation automating this occupation. Not one deployment, not one announcement.
That is worth saying out loud next to a score of 79. The verdict above is about what the work exposes — what current AI could do to these tasks. It is not a claim that anyone has done it. For this occupation those two things have come apart completely: the capability argument is on this page, and the evidence column is empty.
