Lasers Vs LEDs

There is a great deal of controversy and divided opinion over which form of therapy is the better – Lasers that produce coherent light or LEDs that produce incoherent light.

The argument put forward by laser therapy advocates is that only a coherent beam of light penetrates deep into muscle tissue of the body and provides necessary resulting terms of pain relief and injury repair.  The body of scientific study and research evidence backs this up.

The two technologies, lasers and LEDs have totally different biological effects when used.  Some manufacturers of LED therapy units market their products as lasers which is misleading to the public at large.

There are literally hundreds of studies conducted world wide, the overwhelming majority are performed with laser therapy units.  When studies are performed comparing the efficacy of laser beams to LED, the majority have shown laser bean to be the more effective therapy treatment, especially when treating tissue where depth of penetration is required.

The famous laser therapy text book ‘Laser Therapy Clinical Practice and Scientific Background’ by Turner and Hode mentions that the overwhelming view of experts around the world is that laser beams have a deeper stimulating effect and are therapeutically beneficial.

The method used by LED manufacturers is to claim that LEDs are as effective as lasers in treating injuries, however they rely on studies conducted on laser therapy units to support their claims.

The scientific literature supports the view that biostimulative effects of therapy are laser specific in-vivo.  There has not been one study showing that LED is as efficient as laser therapy using coherent light.  The evidence suggest  that LED light is only efficient on superficial levels.

When it comes to Lasers Vs LEDs, laser researchers and experts agree that Lasers are a far superior and effective form of treatment compared to LEDs.

The Laser 3000 uses laser diodes, proven to be the most effective form of treatment compared to LEDs.
