Very Good Book On Low Level Laser Therapy

January 7th, 2008

The best book I ever read on cold laser therapy is called “Low Level Laser Therapy:  A Practical Introduction.  It is by T. Ohshiro and R.G. Calderhead.  Its only drawback is the price–over $250.00!!  And it’s only 145 pages long, but packed with great information.

My advice is to do what I did:  I found it in my local library system, but I had to wait for it.  The book was on loan to a university and it had to be special ordered from there.  I had to wait about 3 weeks for it, but it was well worth the wait.

The best thing about this book are the treatment techniques, especially the “Non-contact Technique” where the laser is held a short distance from the treatment point.  I will expand on this later.  But for now, try to get a copy of this text.


Infrared vs Red lasers. Differences in tissue penetration.

January 6th, 2008

There are basically two types of frequencies used in cold laser therapy: red and infrared.  The common red laser types are 635nm, 650nm, and 660nm.  The power output greatly varies, depending on the manufacturer.  Some common outputs are 5mW, 10mW, and 50mW.  The red frequencies/wavelengths penetrate about 1cm deep into the tissues.  The red lasers are mainly used to treat skin lesions, wounds and acpuncture points.  Many practitioners prefer a little stronger output (10mW or 50mW) to treat acupuncture points since they report quicker and more effective results with the sedation and tonification points.

The infrared frequencies (808nm, 830nm, 904nm) penetrate a lot deeper, about 5cm which is 2 inches.  These are used to treat muscles, joints, and tendons.  The 808nm lasers are actually referred to as ‘near’ infrared since you can still see the light they emit in a dark room.

The advantage of having multiple lasers on one laser head (cluster wand) is simply quicker treatments since you can cover more area.
