What is intratissue percutaneous electrolysis?
Intratissue percutaneous electrolysis, or EPI®, is a minimally invasive technique used in physiotherapy which sets in motion a series of mechanisms that remodel and regenerate tissue. It is a type of complementary therapy.
How is it done?
An acupuncture needle is inserted into the injured area or area which the therapist wishes to treat, and a galvanic current is introduced into the tissue. The overall procedure is as follows:
- Firstly, cryotherapy is performed, which is a jet of cold air that is applied to the skin, numbing the skin and helping to make the puncture as painless as possible.
- An ultrasound is carried out, in order to locate the area which the therapist should focus on. One the ultrasound has been performed, the EPI® procedure can be performed and needles are inserted.
- After the needles have been removed, a high-power laser is applied to the area which has been treated.
Why is intratissue percutaneous electrolysis performed?
EPI® may be performed in order to relieve pain related to:
- Muscle strain
- Tendonitis
- Tendinosis
- Tendinopathies
Studies done in Spain, where the treatment was developed, show promise that damaged tissue has the potential to be treated through EPI® rather than through surgery, meaning the tendon affected or area affected may recuperate without an invasive intervention.
