Use when a task needs the judgment of a physical therapist aide — prepping and reset of treatment rooms between patients, applying pre-set thermal modalities (hot pack, cold pack, paraffin) within safety parameters, assisting patient transport/transfers under supervision, or classifying whether a requested task falls inside or outside the aide's delegable scope. Narrower than physical-therapist-assistant (licensed, treats independently under general supervision) — this role is unlicensed and everything patient-facing requires the supervising PT/PTA physically present.
