In our clinic, this is used more often than not (don’t worry – it’s very comfortable).
The addition of very small amounts of electrical current of specific frequencies has very strong effects on both the local area and the central nervous system/brain.
For instance, a frequency of 1-4 cycles per second promotes endorphin and cortisol production. Endorphins, as you probably already know, are the “feel good” hormones produced by the body to lower pain and promote healing, and cortisol is your body’s natural anti-inflammatory hormone.
