HOW ELECTROTHERAPY WORKS
When it comes to electricity created in the human body, the energy source is chemical and has to do with the composition of the atoms and molecules present. All the elements we take into our bodies, such as oxygen, sodium, potassium, calcium, magnesium etc., have a specific electrical charge. How those molecules are bound together and how they react to other molecules near them is how chemicals create energy. Some of these electrical impulses found naturally in our bodies activate functions needed for healing.
Electricity enables information to circulate in the body, electrotherapy manipulates a specific part of the information by pulsating electrical waves interfering with the transmission of pain signals.
Our nervous system is composed of our brain and our spinal cord, which combine to form the central nervous system; and our sensory and motor nerves, which form the peripheral nervous system. Nerves send information about what is happening in our environment to the brain via the spinal cord. The brain then sends information back to our nerves, helping us to perform actions in response. By treating specific body areas and varying frequency, wavelength and intensity applied, electrotherapy devices can manipulate impulses and target actions to alleviate pain or they can disrupt pain signals.
