BRAZIL. This study compared the effect of single-diode laser and LED cluster before heavy exercise. Only the LED cluster probe decreased post-exercise creatine kinase levels after the Wingate cycle test. This is not a  true comparison of Laser vs LED as the LED irradiance was lower, the total energy was higher and it covered  a larger area. Still the results for the LED are impressive and this paper adds more weight to the validity of LED treatments. Read on …

Abstract Background Data and Objective: There is anecdotal evidence that low-level laser therapy (LLLT) may affect the development of muscular fatigue, minor muscle damage, and recovery after heavy exercises. … Continue reading →

Object This review summarizes the continuous study of low-power laser radiation treatment of a severely injured peripheral nerve. Laser phototherapy was applied as a supportive factor for accelerating and enhancing axonal growth and regeneration after injury or a reconstructive peripheral nerve procedure. In nerve cell cultures, laser phototherapy was used to stimulate activation of nerve cells. Methods Low-power laser radiation was used for treatment of peripheral nerve injury using a rat sciatic nerve model after crush injury, neurorrhaphy, or neurotube reconstruction. Nerve cell growth and axonal sprouting were investigated using laser phototherapy on … Continue reading →

Diode laser beams are hard to measure. They are almost never round, collimated or homogeneous. At best they can be described as being elliptical and having a Gaussian distribution. How do we measure and calculate the area of the ellipse and have the same method used throughout LLLT academia and industry?

Answer: ask The National Physics Laboratory (NPL) to review the problem and propose a solution.

NPL is a world renowned measurements and standards organisation. They play a significant role in the writing of global measurement standards e.g. how to define time (the second) and mass (the kilogram). Now they will be working with THOR to define LLLT beam standards and measurement methods for academia and industry.
