Good laser safety advice on Wikipedia

Posted on 15 November 2008 by James Carroll

I stumbled upon the wikipedia entry for laser safety and I consider it to be a good summary. It deals with all classes of lasers, not just Class 3B commonly used in LLLT. http://en.wikipedia.org/wiki/Laser_safety

How much laser is enough? and how much is too much ?

Posted on 29 October 2008 by James Carroll

In a recent systematic review and meta analysis of laser therapy on tendinopathies (Tumilty et al), 11 out of 20 studies failed to produce a positive result. The reason identified for the ineffective studies were that the laser beams were too strong (the irradiance was too high for this particular pathology). Most clinicians are rightly confused about which laser to choose and which dose or technique will work.

Laser Prevents Muscle Tissue Damage Induced by Snake Venom

Posted on 16 September 2008 by James Carroll

A rat tibialis anterior muscle was injected with venom. Sixty minutes after venom injection, 632.8nm laser (HeNe)  was administered at three incident energy densities. They concluded that HeNe laser irradiation at a dosage of 3.5 J cm2 (the lowest “dose” administered in this study) effectively reduced myonecrosis and the neuromuscular transmission blocking effect caused by the snake venom.
