Interferential Current Therapy
Interferential Current Therapy is used for pain relief, soft tissue healing, and the reduction of swelling. This therapy uses low-frequency electrical charges and when this electricity reaches the affected tissue (by electrodes), and as a response endorphins are released.
The human body is an example of a good conductive medium.
The electric current is a flow of charged (positively or negatively) particles between a conductive medium. Good conductive mediums are the ones that have free-charged particles (electrons or ions) because that characteristic allows an electric current to pass through them. The human body is an example of a good conductive medium (due to the high percentage of water and the presence of Cl- and Na+ ions).
