PT, OT, and ST in the Home
What each therapy discipline does in home health, where the overlaps genuinely are, and when to refer to each other.
The disciplines overlap more in the home than anywhere else, because the home does not divide neatly into mobility, self-care, and communication. Knowing where your colleague's work starts saves the patient a referral they waited three weeks for.
Physical therapy
The question PT answers: can this patient move safely enough to live here?
- Evaluation of strength, range of motion, balance, endurance, and pain
- Gait training, with and without a device
- Transfers — bed, chair, toilet, car, floor recovery
- Stair training, including the actual stairs in this house
- Therapeutic exercise and a home exercise programme
- Fall risk assessment and reduction
- DME recommendation and training — walker, cane, wheelchair
Occupational therapy
The question OT answers: can this patient do the things a day requires?
- ADL retraining — bathing, dressing, grooming, toileting, feeding
- IADLs — meal preparation, medication management, laundry, managing money
- Upper extremity function, fine motor, and coordination
- Adaptive equipment — reacher, sock aid, tub bench, raised toilet seat, adapted utensils
- Home modification recommendations
- Energy conservation and work simplification, which matters enormously in cardiac and pulmonary disease
- Functional cognition — how attention, memory, sequencing, and problem solving play out in real tasks, and compensatory strategies for doing those tasks safely
- Perceptual deficits and vision compensation
Speech-language pathology
The question SLP answers: can this patient communicate, think, and eat safely?
- Speech and language evaluation and treatment — aphasia, dysarthria, apraxia
- Cognition — attention, memory, problem solving, and executive function, including cognitive-communication
- Dysphagia evaluation and management, diet texture and liquid consistency recommendations, and swallowing strategies
- Augmentative and alternative communication
- Voice
Where the overlaps actually are
| Situation | Who leads | Who to bring in |
|---|---|---|
| Patient falls getting out of the shower | PT for transfers and balance | OT for the bathing routine and equipment |
| Patient cannot manage their medications | SLP if the barrier is cognition — memory, sequencing, problem solving | OT for the task itself: organisers, routines, cueing systems. RN for the regimen. |
| Post-CVA patient with weakness and confusion | PT for mobility, OT for ADLs | SLP if communication, cognition, or swallowing is affected |
| Patient is short of breath doing anything | PT for conditioning | OT for energy conservation — often the bigger win |
| Patient is coughing at meals | SLP, urgently | RN for aspiration precautions and monitoring |
| Patient has a new wheelchair | PT for mobility and propulsion | OT for positioning, pressure relief, and reach |
The referral most often missed is OT for energy conservation in heart failure and COPD patients, and the one most often left too late is SLP for a patient who has started coughing at meals.
Cognition: who does what
The split that gets muddled most often, so it is worth stating plainly.
SLP assesses and treats cognition itself — attention, memory, problem solving, executive function, and cognitive-communication.
OT addresses how that cognition plays out in activities — whether the patient can actually carry out a task safely, and what compensatory strategy or set-up makes it possible.
A patient who cannot follow a medication schedule needs both, and they are answering different questions: why the thinking is failing, and what makes the task work anyway.
What applies to therapy exactly as it does to nursing
Therapists new to home health sometimes assume the coverage rules are a nursing concern. They are not.
- The patient must be homebound — a PT-only patient must still meet both criteria. See Homebound Status.
- Each visit must show a skilled need and stand on its own. See What Every Visit Note Must Prove.
- Vital signs and pulse oximetry are taken at every visit by every skilled discipline, not just nursing. See Vital Sign Parameters.
- You can only deliver interventions you have orders for.
- Discharge planning starts at evaluation.
Assistants
PTAs and COTAs deliver a plan the evaluating therapist established. They do not evaluate, do not perform reassessments, and do not change the plan. An assistant who believes the plan should change contacts the therapist — that call is part of the job, not an interruption.
