Interference (IF) therapy is a form of electrotherapy. It is mainly used to relieve pain, relax muscles and stimulate blood circulation and healing processes.

In IF treatment, medium or high frequency electric currents are used and delivered through two channels to different parts of the body. These currents cross inside the body and interact with each other. This is called "interference".

How does it work?

During interference, two currents of different frequencies meet, creating a new low-frequency pulsating current inside the body that is concentrated in the affected area. This technique can work more deeply than simple electrical stimulation because the low-frequency current is able to penetrate tissues more effectively, resulting in better results in terms of pain relief and healing.

What is it used for?

  • Pain relief: Interference (IF) treatment can relieve chronic and acute pain, such as muscle aches, joint pain and other aches and pains.
  • Muscle Relaxation: Helps to relax spasmodic, tense muscles, which is particularly useful for athletes and people with musculoskeletal problems.
  • Promote healing:Improves circulation, which can lead to faster regeneration and wound healing.
  • Reducing inflammation: IF treatment can also have an anti-inflammatory effect, which also helps to reduce pain and swelling.

Contraindications

There are certain situations where interference treatment is not recommended. These include:

  • Pacemakers or other electrical devices: IF treatment may interfere with older types of implanted devices.
  • Pregnancy: Treatment is not recommended for pregnancy in the abdomen.
  • Tumour: IF treatment is not recommended in areas where tumours are present. However, it may be used away from tumours.
  • Acute Infections: Treatment of inflamed and infected areas is not recommended as the current may increase inflammation.
  • Thrombosis: Treatment over a blood clot may increase the risk of clot displacement. However, the area away from the site of the thrombosis can be treated.
  • Epilepsy:Treatment can trigger seizures in some cases, so patients with epilepsy should exercise extra caution, especially when treating the head-neck-chest region.

If treatment is usually administered by physiotherapists or rehabilitation specialists as part of an individualised treatment plan, and in many cases combined with other forms of treatment for maximum effectiveness.
