Which three electro therapies utilize alternating current?

1. Microcurrent, Fradic, High frequency

2. High frequency, Fradic, Sinusoidal

3. Galvanic, Iontophoresis, Anaphoresis

4. Cataphoresis, Photo-therapy, Microdermabrasion

The correct answer is: High frequency, Fradic, Sinusoidal

The correct answer is based on the understanding of various electro therapies and the types of current they use. High frequency, Fradic, and Sinusoidal therapies all utilize alternating current (AC). High frequency treatments are commonly used in skin care for their thermal and germicidal effects. They work by creating an oscillating electrical current that produces high-frequency waves, which can help stimulate circulation and improve the overall tone of the skin. Fradic therapy, also known as faradic current, uses a particular type of alternating current to stimulate muscles in a non-invasive way. It provides a series of short bursts of electricity that cause muscle contractions, which can improve muscle tone and enhance the appearance of the skin. Sinusoidal current is a specific type of alternating current characterized by a smooth, wave-like pattern. It is often used for deeper penetration into tissues, promoting healing and relaxing muscles. On the other hand, the other options consist of electro therapies that either do not use alternating current or are not typically categorized under electro therapies involving AC. Galvanic, Iontophoresis, and Anaphoresis utilize direct current (DC), while Cataphoresis, Photo-therapy, and Microdermabrasion do not involve the use of alternating current
