Laser therapy sounds like a serious type of treatment. However, it really isn’t something you should worry about at all. It assists with pain relief and stimulates healing in your own tissue. And most of the time you won’t even feel anything when it is applied. This article will explain to you exactly what you can expect from laser treatment.
When you think of laser, you might think of laser hair removal or laser eye surgery or maybe you’ve seen someone shine a laser pointer on a screen. But have you ever heard of laser being used as a treatment by physiotherapists? There are two types of laser, one being high powered lasers, which are used in commercial industry and engineering settings. However, physiotherapists use the type of laser that is called “Low Level Laser Therapy” and this type is very safe and painless to use on your skin and tissues.
What exactly is Laser?
The term LASER is the acronym for: Light Amplification by Stimulated Emission of Radiation. Basically, laser is a type of light and it has very specific qualities namely: it is monochromatic, collimated, and coherent. A laser is a device that produces such light.
Now, that’s a mouthful. Let’s simplify these concepts. Light consists of waves, the same as sound waves. The light waves coming from a laser, has very specific qualities. It needs to be light waves of exactly the same colour, frequency and wavelength. And the waves move precisely parallel to each other. This creates a very concentrated, precise beam of light. Light coming from a laser, is created by a specific process within the laser device to cause the controlled emission of radiation.
Why we use laser
Your skin is the organ that is naturally exposed to light more than any other organ in your body. It responds in different ways to different types of lightwaves. For example: infrared wavelengths cause warmth in your skin and ultraviolet (UV) wavelengths cause a change in skin color. Laser light also gets absorbed through your skin and it affects the function of your connective tissue cells (fibroblasts), accelerate connective tissue repair and act to decrease inflammation.
So, laser therapy is a non-invasive light source treatment that emits no sound or vibration and very little to no heat. It has been shown to promote healing in your own tissue and that is why it is used by physiotherapists to treat various musculoskeletal conditions.
