At movement perfected we use Interferential therapy for non invasive promotion of healing and pain relief. It can treat pain associated with
- Back, Neck, Shoulder and Knee injuries or problems
- Joint injuries
- Overuse injuries and surgical procedures
- Edema, Inflammation
- Carpal Tunnel Syndrome
- Tennis Elbow
- Sports Injuries
How Interferential Therapy works
Interferential therapy delivers a continuous stimulation deep into the affected tissue. The stimulation both blocks pain and reduces swelling and inflammation which can cause pain. Interferential. 4 pole interferential works by putting two signals into the tissue at slightly different frequencies. Where they cross over, the two signals “interfere” to produce a lower frequency, therapeutic current. In theory, this interference current is generated in the pattern shown in the diagram. In practice, the tissues do not conduct uniformly, so the currents rarely interfere in the expected target area.
Effects of Interference Frequencies
Physiotherapists believe that the low frequency interference currents have the following effects:
2Hz – Around this frequency the metencephalins are stimulated – resulting in short term pain relief.
10Hz -This frequency has a beneficial effect on the immune system and tends to make patients wakeful yet relaxed.
130Hz – This frequency stimulates the production of endorphins and results in longer term pain relief and some local anaesthesia.
1-100Hz – This frequency sweep will increase the inflammatory rate.
45 – 90Hz – This frequency sweep will depress the sympathetic nervous system so allowing increased activity of the parasympathetic system, and increase the blood supply.
If Interferential Therapy is used as part of a treatment regime it is always used in conjunction with education and other therapies, such as exercise.
