The Physical Therapy Practice Act of the State of Arizona defines Physical Therapy as “Practice of physical therapy” means:
Examining, evaluating and testing persons who have mechanical, physiological and developmental impairments, functional limitations and disabilities or other health and movement related conditions in order to determine a diagnosis, a prognosis and a plan of therapeutic intervention and to assess the ongoing effects of intervention.
EMG/NCS Testing uses electricity and Musculoskeletal Ultrasound uses sound waves for the evaluation (testing and measurement) of the neuro-musculoskeletal system.
The Arizona Board of Physical Therapy has explicitly defined Musculoskeletal Ultrasound Imaging within the Scope of the PT profession.
APTA fully supports PTs practicing EMG/NCS Testing as it is within the scope of Physical Therapy Practice. The Orthopedic Section of the APTA in a white paper not only advocates the use of Musculoskeletal Ultrasound Imaging within the scope of practice for Physical Therapy but also endorses its application both for diagnostic as well as procedural purposes to aid neuromuscular re-education, dry needling and electroneuromyography.
