Conclusion by: Reza Abusaidi, DC
Based on the results of our pilot study we may conclude that high intensity laser therapy could be recommended as a treatment of choice for reduction of pain and improving of function in patients with osteoarthritis of the knee.

The short-term effectiveness of high-intensity laser therapy (HILT) was investigated as a retrospective case series for the treatment of the pain and disability associated with subacromial impingement syndrome (SAIS).

Conclusion by: Reza Abusaidi, DC
High-intensity laser therapy was found to be effective in the short term in the treatment of pain and disability in patients with subacromial impingement syndrome.

The purpose of this study was to investigate light transmission of continuous wave (CW) 810 nm wavelength light and 904 nm wavelength super-pulsed light through skin and gastrocnemius muscle and skin only using an anesthetized Sprague-Dawley rat model.
The percentages of light transmission (fluence rate) through muscle and skin were 7.42% (810 nm wavelength) and 4.01% (904 nm wavelength) and through skin were 24.63% (810 nm wavelength) and 19.94% (904 nm wavelength). These data prove that transmission of CW 810 nm wavelength light through muscle and skin and skin alone is greater than transmission of super-pulsed 904 nm wavelength light.

Conclusion by: Reza Abusaidi, DC
It has been previously reported that super-pulsing 904 nm wavelength light increased depth of penetration over time due to photo-bleaching. Based on our data, the observed increase in light penetration over time was due to an insufficient warm-up period of the super-pulsed laser.

 

LLLT in postexercise skeletal muscle recovery

A study about LLLT in postexercise skeletal muscle recovery and performance concluded that pre-exercise low-level laser therapy, mainly with 50 J dose, significantly increases performance and improves biochemical markers related to skeletal muscle damage and inflammation. 

 

Laser Therapy for Chronic Osteoarthritis of the Knee
Effect of Laser Therapy on Chronic Osteoarthritis of the Knee in Older Subjects.

Article:
https://www.ncbi.nlm.nih.gov/pubmed/27330707

This research article that was published in Journal of Lasers in Medical Sciences in 2016 concluded that addition of Low-Level Laser Therapy to exercise training program is more effective than exercise training alone in the treatment of older patients with chronic knee Osteoarthritis and the rate of improvement may be dose dependent, as with 6 J/cm(2) or 3 J/cm(2).

High Power Laser for Treatment of Achilles Tendinosis – a Single Blind Randomized Placebo Controlled Clinical Study.

Conclusion by: Reza Abusaidi, DC
The results indicate that high power laser treatment may provide a future option for treatment of Achilles tendinosis related pain, but further studies are warranted.
