7.3 Advanced Practice Standards, Electromyography & Administration of Topical Medications

Advanced Practice Standards: EMG and Topical Medications

While the general scope of physical therapy practice is broad, certain advanced procedures require specific, documented postgraduate training or operate under strict legal limitations regarding the physical therapist's authority. Electromyography (EMG) and topical-medication administration are not separate FSBPT outline codes; they support 4200 Components of care / Standards of Practice (Rules 64B17-6.003 and 64B17-6.006 appear on the outline under 4200). These topics highlight the boundaries of the physical therapy scope of practice in Florida and the intersection with medical and pharmacy laws.

Electromyography (EMG) Certification Requirements

Electromyography (EMG) is an invasive electrodiagnostic procedure used to evaluate the health of muscles and the nerve cells that control them. Because it involves inserting needle electrodes directly into muscle tissue to record electrical activity, the potential for patient harm (infection, nerve damage) is significant.

Accordingly, Rule 64B17-6.003 (Minimum Qualification to Perform Electromyography)—implementing the EMG limitations in the practice definition under F.S. 486.021—establishes exceptionally high barriers to entry for physical therapists wishing to perform EMG. (Do not confuse Rule 64B17-6.008, which is dry needling.) A standard physical therapy degree does not qualify a PT to perform this procedure.

The Training Mandate

To be legally permitted to perform EMG in Florida, a physical therapist must complete a rigorous two-part certification process:

1. Didactic Education (50 Hours): The physical therapist must complete at least 50 hours of instruction in a university or collegiate setting, or a course approved by the American Physical Therapy Association (APTA). This coursework must cover relevant anatomy, physiology, neurophysiology, pathology, and the physics of electricity as it applies to electrodiagnostic testing.
2. Clinical Experience (200 Hours): Theoretical knowledge must be backed by extensive, closely monitored clinical practice. The PT must complete at least 200 hours of clinical experience in human electromyography.
   • Supervision is Mandatory: These 200 hours MUST be conducted under the direct supervision of a licensed physician (MD or DO) trained in EMG, or a physical therapist who has already met these requirements and is legally permitted to perform EMG.
   • Patient Volume: During these 200 hours, the physical therapist must perform tests on at least 100 neurologically involved patients.

Exam Trap: Be very careful distinguishing between the requirements for Dry Needling (50 hours / 25 sessions) and EMG (50 hours / 200 hours / 100 patients). The exam frequently mixes these numbers in the distractor options to test your precision.

Administration of Topical Medications (Rule 64B17-6.006)

Physical therapists frequently use modalities like iontophoresis (using electrical current to drive medication through the skin) and phonophoresis (using ultrasound to drive medication). These procedures utilize topical medications, typically corticosteroids (like dexamethasone) or local anesthetics (like lidocaine).

Florida law places strict parameters around how a physical therapist interacts with these pharmacological agents to prevent the unauthorized practice of medicine or pharmacy.

The Core Rule: Administration vs. Prescribing

• Administration is Allowed: Physical therapists are legally permitted to administer topical medications that are required for use in conjunction with physical therapy modalities (like ultrasound or electrical stimulation).
• Prescribing is Prohibited: Physical therapists have absolute zero prescribing authority. A PT cannot decide a patient needs dexamethasone and write an order for it.
• Dispensing is Prohibited: A PT cannot dispense medication (e.g., hand a patient a tube of prescription hydrocortisone to take home).

The Prescription Requirement

For a physical therapist to administer a prescription topical medication, there MUST be a valid prescription from a licensed practitioner authorized by law to prescribe such medication (e.g., a physician, osteopath, dentist, podiatrist, or authorized advanced practice registered nurse/physician assistant).

Clinic Protocols and Storage

When handling medications, the physical therapy clinic must operate almost like an extension of a pharmacy regarding safety and record-keeping:

• Labeling: Medications must be maintained in their original, properly labeled containers.
• Storage: Medications must be stored safely, securely, and in accordance with the manufacturer's temperature and environmental requirements.
• Patient-Specific: If a medication is prescribed for a specific patient, it can ONLY be used for that patient. A clinic cannot use a "community tube" of prescription dexamethasone for multiple patients unless the clinic has specific legal authorization to bulk-order and stock the medication (which is complex and generally handled through a medical director).
• Documentation: The administration of the medication, including the drug name, dosage (if applicable), modality used, and patient response, must be meticulously documented in the treatment note.

Clinical Scenario: Iontophoresis

Scenario: A patient arrives with a prescription from their orthopedic surgeon that reads: "Physical Therapy: Evaluate and Treat. Implement iontophoresis with dexamethasone for lateral epicondylitis."

Action Required:

1. The PT evaluates the patient and confirms iontophoresis is indicated.
2. The PT CANNOT supply the dexamethasone from a hidden stash. The patient must either bring the medication dispensed by a pharmacy, or the clinic must have legally obtained it specifically for that patient via a pharmacy.
3. Once the medication is legally present, the PT applies the prescribed dexamethasone to the iontophoresis pad and administers the treatment.
4. The PT documents the administration of the specific drug via iontophoresis in the daily note.

Summary of Specialty Procedures

Understanding the distinction between the physical therapist's role (administration) and the physician/pharmacist's role (prescribing/dispensing) is critical for passing the jurisprudence exam and practicing safely within legal boundaries.
