3B vs Class IV Lasers

Laser overdose - How much is enough? How much is too much ?

Lies, damn lies and no statistics (they call it marketing)

3B	Class IV
Almost all the laser research evidence for tissue repair inflammation and pain is with class 3B lasers and LEDs.	Class IV laser companies use class 3B evidence to promote their products because they don't have much of their own.
3B laser systems cost less.	There is zero published evidence to show that a class 4 laser penetrates deeper than a high powered 3B laser.
3B lasers are safer.	If the Class IV laser is in the 940 - 980nm wavelength range then it will penetrate less than a class 3B laser in the 800nm to 900 nm range.
3B lasers have less stringent regulations (rules vary by country and state).	It is a lie when they say that there is evidence that more power is more effective. The evidence is the complete opposite.
	Class IV laser can burn the skin if not used carefully.
	Class IV laser use fibre optic cables which break easily and cost hundreds of $$$ to replace.

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

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.

LLLT companies may be no better than Big Pharma

It is a popular sport in the LLLT industry to sneer at Big Pharma for their side effects and marketing practices, but the LLLT industry is far from criticism itself. Whilst LLLT side effects are hard to find, marketing overstatement and misdirection are common place. In July's literature watch is a paper titled "The Effectiveness of Therapeutic Class IV (10 W) Laser Treatment for Epicondylitis". This small study showed that 10 Watt Class IV laser (mixed 8W 970nm, 2W 810) was successful in reducing pain and improving function in an RCT with 15 patients, and that there was good statistical significance at 6 months following a course of 6 treatments.
