Cold Laser Therapy is the newest FDA approved device for healing. With over 3000 published medical articles, it is one of the most studied medical devices on the market; it is proven effective for many conditions as well as being safe without side effects.
When people hear the word “ultrasound” the first thing that comes to mind is the ultrasound from the OB-GYN where you can view a 2-dimensional or 3-dimensional image of what’s inside your tummy. But, this therapy is not this type of ultrasound as it is a therapeutic procedure that uses sound waves in treating injuries such as with soft tissues, muscles or joints.
The sound waves would vibrate at a frequency that is higher than the range that human ears could hear and it provides a mechanical vibration that provides a micro-massage. I can either be a thermal or non thermal application at frequencies ranging from 0.72 MHz to 3 MHz.
Electric stimulation rehabilitation or electrotherapy had been discovered way back in 400 BC with the help of a torpedo fish that produces an electric shock reaching up to 150 volts. People used to take these fish from streams and they place them on the body’s painful area and the electricity produced from the fish controlled the pain.
It was when the gate control theory of pain in 1965 that reintroduced electric stimulation rehabilitation after it had lost the interest of many skeptics in the nineteenth century. The theory suggests that when the large nerve fibers activity increases, it tends to close the gate blocking information or signals of pain to the brain.
