Reduction Of Chronic Musculoskeletal Pain With Cranial Laser Reflex Technique (CLRT): A Randomized Controlled Trial Using Pressure Algometry
Cranial Laser Reflex Technique (CLRT) is a novel method involving a brief low level laser stimulation of specific cranial reflex points to reduce musculoskeletal pain. Objective: The objective of the study was to compare the immediate effects of CLRT with a sham treatment on chronic musculoskeletal pain using pressure algometry in a double‐blinded randomized controlled trial. Methods: Fifty‐seven (57) volunteers with various musculoskeletal pains gave informed consent and were randomly allocated to either the CLRT treatment or sham group. Painful trigger points and/or tender spinal joints were found in each patient. Using a digital algometer, the pain/pressure threshold (PPT) was determined and a pain rating was given using a numerical pain scale from 0–10. CLRT or a sham treatment was performed with a 50 mW, 840 nm laser, for a maximum of 20 seconds to the each cranial reflex. The initial pressure (PPT) was immediately delivered to the same spot, and the pain rated again. Results: There was a statistically significant difference in pain scores between CLRT and sham groups immediately following treatment. Improvement was reported in 95% of the treatment group, with 59% reporting an improvement of 2 points or greater. The average change in pain scores in the treatment group was 2.6 points versus negligible change for the control group. Conclusion: The results show that CLRT is effective at immediately reducing chronic musculoskeletal pain. Further studies are needed with additional outcome measures to.
