What is interferential current therapy (IFC)?
Interferential current therapy (IFC) is a treatment used to relieve pain, decrease inflammation, decrease muscle knots or spasms, and aid in restoring motion and soft tissue healing. It produces electrical currents that pass through the affected area of the body which decrease swelling, reduce pain, and decrease muscle spasms. The uncomfortableness of a frozen shoulder or pinched nerves can be altered by this therapy, stimulating circulation and promoting soft-tissue healing.
What are the benefits of IFC?
This therapy has a number of therapeutic physiological effects in addition to treating the affected area, including
- An increase in localized blood flow, which can improve healing by reducing swelling (the additional blood flowing through the area takes edematous fluid away with it). It also helps to remove damaged tissue, bring nutrients necessary for healing to the injured area, increase the permeability of the cells, and improve venous and lymphatic systems.
- The stimulation of local nerve cells, which can have a pain-reducing/anaesthetic effect by potentially blocking the transmission of the pain signals (pain gate mechanism) at the spinal cord level. It can also stimulate the release of pain reducing endorphins (opioid mechanism).
- Muscle stimulation, which allows the muscle spasm to decrease and overcome some of the muscle inhibition, often caused by local injury and swelling.
