Interferential Current Therapy
This type of electrical therapy allows for deeper penetration of electrical stimulation into the body than other types of electrical stimulation such as TENS or muscle stimulation. The effect of that deeper stimulation is to interfere with the transmission of pain messages at the spinal cord level, improving circulation and decreasing inflammation.
In Interferential Current Therapy, the stimulators use a fixed carrier frequency of 4000Hz per second with one of the stimulators carrying a variable Hz frequency of 4,001 to 4,150. The effect of two leads with the same frequency (4,000 Hz) is that they are canceled out after delivering the narrower frequency band deep into the tissues. If just the frequency of 1-150 Hz was delivered to the skin, it could not penetrate to the deeper tissues. The machine is then set with a certain frequency level depending on the desired effect (eg. acute pain, chronic pain, subacute pain). Treatment times may vary from 12 to 15 minutes.
At Weber Chiropractic Office, SC, Interferential Current Therapy is used for hip bursitis, deep spinal pain (as in old yet still painful spinal compression fractures), shoulder pain or other pain syndromes that are resistant to other therapies.
Our unit also allows for Russian muscle stimulation and anesthesia of areas.
Therapeutic Ultrasound Therapy uses sound wave frequencies greater than 20,000 cycles per second that can penetrate to a depth of 4 to 6 cm in the body. Ultrasound can be applied in either pulsed or continuous waves. We most commonly use pulsed sound in our office because there is acute inflammation in the area, and we want to help break up the inflammatory pockets that causes the pain. It’s like the waves of a boat hitting the beach – but at thousands of times per minute – gradually breaking down the inflammation. At times, continuous sound is used when we need to heat up the deep tissues of the body or scar tissue. Ultrasound is very soothing and is commonly used after manipulation to help calm the patient and their muscles and ligaments – promoting healing.
