Class 3 Vs Class 4 Laser Therapy

Assessment of feasibility and efficacy of class iv laser therapy for postoperative pain relief in off pump coronary artery bypass surgery patients.

Class 3 vs class 4 laser therapy.

If the class iv laser is in the 940 980nm wavelength range then it. As an example a class 4 laser emitting 880 and 970 nm laser light at 10 w average power with a beam surface area of 10 cm producing a radiant exposure of 1000 mw cm thus exceeding the safe exposure limits known as the maximum permissible exposure limits mpe which range from 200 mw to 500 mw cm depending on wavelength. Knowing the difference and how each will affect the type of treatment you can provide is important when deciding on a laser therapy system. But the standard class 3b laser turned out to be a very weak laser pointer.

Basics of laser classification. It will be listed either in arabic numerals 1 2 3r 3b 4 or in roman numerals i ii iiia iiib iv. 2013 45 5 311 317 17 karlekar a bharati s saxena r mehta k. Many people that don t get results with a class 3b and below will get results with a class 4.

Thus a class 3b laser can penetrate deeper into tissue than a class iv laser and can therefore saturate the target faster. Class 4 cold lasers may be the ultimate therapy laser for many applications but that really depends more on the requirements of the practice. This is not an obsolete printout it is a state of the art app that runs on a phone tablet or computer. Others offer pulsing to allow for heat dissipation.

3b lasers are safer. The effectiveness of therapeutic class iv 10w laser treatment for epicondylitis. The class iv studies are still few and sometimes surprisingly biased. The bottom line is that class 4 system deliver results.

Most laser products are required by law to have a label listing the class. Laser classes lasers are classified for safety purposes based on their potential for causing injury to humans eyes and skin. One paper 5 claims that class iv laser produced better healing of oral mucositis than a standard class 3b laser. There is zero published evidence to show that a class 4 laser penetrates deeper than a high powered 3b laser.

This app follows the best practices for laser therapy and dynamically creates pictorial treatment plans for over 250 different conditions for humans pets and horses. The heat buildup by class 4 is negative and some manufacturers add cooling to the beam. One of the major differences between laser therapy systems is whether they are a class iii 3 or class iv 4 laser device. Class iv laser companies use class 3b evidence to promote their products because they don t have much of their own.

The industries best protocol library every laser comes with the laser therapy us protocol library and training tool. Remarkably these references are generally class 3b studies. The k cube 4 is a high powered class iv therapy device with power adjustable from 100 milliwatts to 15 000 milliwatts 15 watts allowing for a wide range of treatment protocols.
