Interferentials in soft tissue rehab

What is interferential therapy?

Interferential therapy is a deep type of TENS (Transcutaneous Electrical Nerve Stimulation) which has two alternating currents of low frequency that are applied to the skin. 

Either two or four electrode pads (with a damp sponge) are applied around the area that needs to be treated. The two electrical currents alternate and “interfere” with or intercept each other, causing beat frequencies which contract the muscles for rehabilitation and relieves pain.

Our podiatrists utilise the controls on our interferential machine to adjust the strength of the current and the type of nerve stimulation required. 

How will interferential therapy help me?

Interferential therapy can help in the following ways:

  • Pain relief

  • Interferential stimulation of the nerves causes the central nervous system to facilitate the release of endorphins (pain relieving chemicals) into the body, and interferes with the pain transmission messages at the spinal cord level. 

  • Muscle stimulation

  • Interferential therapy stimulates a weak muscle by causing it to contract repetitively which will help the muscle regain its function, strength and endurance. Following an injury, it is important to stimulate the muscles to get them strong and working to full capacity again.

  • Increased local blood flow

  • The stimulation of nerves causes vasodilation - an increase in blood flow to the injured area, increasing healing rates and also contributing to pain relief.

  • Reduction of swelling/oedema

  • The vasodilation in the blood vessels due to interferential therapy results in the removal of inflammatory toxins and therefore reduces swelling/oedema.

What injuries can interferential therapy be used for?

  • Soft tissue injuries

  • Swelling and oedema

  • Wasting of muscles e.g. following a stroke or immobilisation post surgery/fracture

What will I feel during the treatment?

You will feel a tingling sensation or pins and needles, or even a slight cramp depending on how strong the current is. You may notice the muscles twitching or contracting.

How long is a treatment session and how many sessions will I need?

Interferentials are used in conjunction with pain management tools such as laser, ultrasound and shockwave therapy. The interferential treatment itself can range from anywhere between 5 to 20 minutes, however we recommend at least 4 sessions once your pain levels have reached a 2/10 on the VAS scale for proper rehabilitation.
