Final answer:
A licensed Massage Therapist may not assist with Ultrasound or electronic muscle stimulation (EMS), even if they are registered as a Chiropractic Assistant.
Step-by-step explanation:
A licensed Massage Therapist may not assist with Ultrasound or electronic muscle stimulation (EMS), even if they are registered as a Chiropractic Assistant. This is because the use of these modalities requires specific knowledge and training beyond what a Massage Therapist is typically trained in. Ultrasound and EMS are commonly used in physical therapy to treat injured or overworked muscles, and require skill to avoid tissue damage. Therefore, it is important for a Massage Therapist to refer patients to a qualified professional, such as a Physical Therapist, for these types of treatments.
