Final answer:
A Physical Therapist Assistant (PTA) cannot modify treatment techniques in a plan of care; that responsibility is exclusively the Physical Therapist's.
Step-by-step explanation:
The statement that a PTA (Physical Therapist Assistant) may modify treatment techniques as indicated in the plan of care is false. PTAs are trained to administer treatments outlined by the plan of care developed by the supervising Physical Therapist. However, the responsibility of making modifications to the treatment plan, including changes in treatment techniques, rests solely with the Physical Therapist. While PTAs play a crucial role in delivering care and may provide valuable feedback, they do not have the autonomy to make changes to the prescribed treatment without the approval of the Physical Therapist.
