The Physical Therapy Practice Act of the State of Nebraska defines Physical Therapy testing as:

38-2917. Testing, defined. Testing means standard methods and techniques used to gather data about a patient. Testing includes surface electromyography and, subject to approval of the board, fine wire electromyography. Testing excludes diagnostic needle electromyography. Source: Laws 2006, LB 994, § 135; R.S.Supp.,2006, § 71-1,379; Laws 2007, LB463, § 1010. Operative date December 1, 2008.

So, a case could be made that a PT would not be able to perform needle EMG independently. However, Nerve Conduction Studies are not invasive studies as they only involve surface electrodes. Other Electrodiagnostic studies such as Evoked Potential Studies (SSEP, VEP, BAERs) as well as Musculoskeletal Ultrasound Imaging are not invasive studies as there is no penetration of the integrity of the skin.

EMG/NCS Testing uses electricity and Musculoskeletal Ultrasound uses sound waves for the evaluation (testing and measurement) of the neuro-musculoskeletal system.

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.
