Laser for Treatment of Pain-Low Level Light Therapy (LLLT)

The fact that biological systems react to light is no mystery.  When light strikes the leaves of a tree it initiates a biochemical reaction which generates energy for the plant to use.  In a similar fashion the human body also responds to light exposure.  The sense of sight is possible through a biochemical reaction that takes place when light contacts the eyes.  The skin also reacts to natural light through a number of biochemical processes; these processes are responsible for darkening of the skin (“getting a tan”) and the body’s production of vitamin D.

LLLT, also known as “photobiomodulation,” takes advantage of the body’s reactions to different spectrums of light in order to improve healing, decrease inflammation and even reduce pain.  The spectrum of light used in LLLT is in the far-red to infrared region of the spectrum.  Light in this range does not cause heating of the area being treated and has been proven to stimulate the body’s natural processes. 

Experimental data has shown that LLLT stimulates cellular mitochondria.  Mitochondria are the cell’s natural “power house” and provide the energy needed for proper cellular functioning.  Acceleration of cellular and tissue repair have also been observed in experimental models.  When used in clinical studies LLLT has proven to be useful in reducing inflammation in pediatric bone marrow transplant patients, and provided pain relief for patients suffering from joint and muscle pain.  LLLT offers an advantage over other therapies due to its non-invasive nature and lack of significant side effects.  Although it is a relatively new form of therapy, the potential applications of LLLT treatment are widespread.

Nexus 10W Laser

The Nexus 10W laser is a state-of-the-art class IV laser capable of providing the benefits of LLLT.  These benefits include improved healing time, pain reduction, increased circulation and decreased swelling.  LLLT can aid in the treatment of many types of patient complains.  Some treatable conditions of the lower leg and foot include (but are not limited to) heel pain, sprains, tendonitis, and bursitis.  Laser treatments only require a short amount of time and are capable of providing drug free pain relief.  The duration and frequency of treatment may differ depending on the condition/injury, and should be determined by the physician.
