Interferential therapy (IFT) is a type of electrical stimulation therapy that uses low-frequency electrical currents to reduce pain and inflammation. It is a safe and effective treatment for a variety of conditions, including arthritis, tendonitis, and muscle spasms.
How IFT Works
IFT works by delivering two medium-frequency electrical currents to the body. These currents interfere with each other, creating a beat frequency. The beat frequency is the difference between the two medium frequencies. It is this beat frequency that is thought to be therapeutic.
The beat frequency can be adjusted depending on the desired therapeutic effect. For example, a lower beat frequency is used to reduce pain, while a higher beat frequency is used to increase muscle strength.
Benefits of IFT
IFT has several benefits, including:
- Pain relief: IFT can be effective in reducing pain from a variety of conditions, including arthritis, tendonitis, and muscle spasms.
- Reduced inflammation: IFT can help to reduce inflammation, which can also help to reduce pain and swelling.
- Improved circulation: IFT can help to improve circulation, which can help to speed healing and reduce pain.
- Muscle relaxation: IFT can help to relax muscles, which can improve flexibility and range of motion.
Conditions Treated with IFT
IFT can be used to treat a variety of conditions, including:
- Arthritis
- Tendinitis
- Bursitis
- Muscle spasms
- Back pain
- Neck pain
- Knee pain
- Shoulder pain
- Peripheral neuropathy
What to Expect During IFT Treatment
IFT treatment is typically performed by a physical therapist. During treatment, the therapist will place electrodes on the skin over the area to be treated. The therapist will then adjust the intensity and frequency of the currents.
A typical IFT treatment session lasts for 15-20 minutes. Treatment may be needed several times a week for several weeks.
Risks and Side Effects of IFT
IFT is generally safe and well-tolerated. However, there are a few potential risks and side effects, including:
- Skin irritation: The electrodes may cause some skin irritation.
- Muscle soreness: IFT can cause some muscle soreness.
- Electrical burns: In rare cases, electrical burns can occur.
IFT is not appropriate for everyone. People with certain medical conditions, such as pacemakers or pregnancy, should not undergo IFT treatment.
Conclusion
IFT is a safe and effective treatment for a variety of conditions. It can help to reduce pain, inflammation, and muscle spasms. If you are considering IFT treatment, be sure to talk to your doctor to see if it is right for you.
