I was thinking about fields with mid-levels who have a pretty large scope, like CRNAs or optometrists. Is PT similar, or is it just that the two fields work together but have different capabilities?
CRNAs have the same job for gas and do the same treatment with oversight. PAs and NPs (if not a first assist in surgery or an extra pair of hands) have the same job as primary care and do the same treatment with restricted legal scope under the attendings license.
Optometrists treat differently than ophthalmologists....one is surgical and does meds, the other prescribes glasses and contacts etc. Psychologists use psychotherapy and counseling primarily while psychiatrists focus on psychopharmacology
Therapists use therex, modalities that don't enter the skin, and manual therapy (or graded physical stress) as treatment for functional impairments following disease or injury and help facilitate healing. Usually progressing from passive to active treatment. Physiatrists do high level procedure or pharmacological intervention for patients primarily but have crossover with fitting orthotics and prosthetics etc. depending on the work and collab model. Both will treat the same patients generally but use different approaches.
Inpatient is the most collaborative. Physiatry does the medical management for serious trauma or neuro cases, treats, and coordinates the rehab plan with speech therapy, occupational, and physical. Followups with aquatic therapy etc. are reported and monitored and the physician adjusts things.
Outpatient Physiatry does more primary care and sports medicine utilizing injections to my understanding. Spine and trauma go with it for pain medicine as well for fellowships I believe. In some setups, Physiatry will refer patients and send imaging to the Ortho or sports therapists who create a rehab plan after the initial visit.
In other settings, particularly with surgeons and therapists only, the therapist just does differential dx for low level pathology themself and creates the rehab plan or progresses patients from post op back to withstanding high physical stresses.
So it's much more similar to the optom/optho and psychology/psychiatry field dynamics. Treatments differ and complexity of patients may need more physician management or not. The treatment is adaptation, habituation, compensation, and substitution which work with disease form/function deficits or facilitating neuroplasticity for neuromusculoskeletal issues as opposed to procedure and pharmaceutical interventions for the same problems when necessary. Other physician collaborations include:
-Neurological outpatient following neurosurg or neurology
-ENT collab with vestibular and dizziness issues
-Hospitalist collab with acute/subacute positioning and secondary/tertiary complication prevention (this is the most general hospital work)
-Ob/gyn collab for pelvic floor dysfunction and retraining or pain during the pregnancy process or birth
-Oncology for lymphedema management using manual techniques and sleeves for drainage
-Pediatric developmental delay with PCPs to facilitate strength and motor control for activities for developmental milestones
-HH and snf for basic independence or palliative care with internal medicine
