General overview

LLLT (Low-Level Laser Therapy) is a non-invasive method of applying a low-intensity laser or LEDs to the surface of the body. The method was discovered by Endre Mester in the 1960s and has undergone numerous medical and commercial developments since then.
LLLT is also known as photobiomodulation (PBMT), cold laser therapy, low intensity light therapy and soft laser therapy. 
Studies have confirmed that these light therapies have excellent analgesic properties, as well as the ability to improve cell function, including the performance of the mitochondria (which produce energy for all the cells in the body). The use of red light reduces oxidative stress and improves the metabolism of various cells, reduces inflammation.

QRI (Quantum Reflex Integration) is a process based on LLLT, using in addition the use of sound and movement to promote reflex integration in children.

Main objectives of the method

LLLT was traditionally used to relieve certain pains and to stimulate optimal cell function, reduce inflammation and oxidative stress. It is now also used in the head to treat certain neurological disorders by stimulating neural networks.
The light emitted by the device is absorbed by the mitochondria (responsible for energy production in the body): cellular energy production increases and the surrounding tissues will be stimulated.


QRI combines laser (LLLT), music (specific frequencies) and archaic reflex integration movements (see sheet: reflex integration). The underlying idea is that poorly integrated or poorly developed reflexes can impede learning, behaviour, and be the cause of several motor, behavioural or cognitive disorders.

Specificities of the method

The method is safe, non-painful. The laser does not produce any heat ("cold laser"). Studies show that it has no negative effects, and that its results are quite positive. Several successive sessions are necessary. LED devices are available to the general public, making it a safe therapy that can be practiced at home. However, there are no devices that use the same lasers as in a clinic, as these can be dangerous if used improperly.

QRI machines are for sale on the official website. They are to be used mainly at home, with instructions provided or practiced by professionals trained in the method (abroad).

Who is this method for ?

LLLT is considered a viable treatment for serious neurological disorders such as head injuries, strokes, spinal cord injuries and degenerative diseases of the central nervous system.

















The QRI is for patients suffering from :

  • Attention Deficit Disorder

  • Autism

  • Dyslexia

  • Learning Disabilities

  • Memory disorders

  • Engine development

  • Social Behavioural Disorders

  • Expression disorders

  • Behavioural disorders

  • Emotional Disorders

What parents say about it

"I ended up in a wheelchair following a training accident as a racehorse trainer. I know the LLLT very well. Believe me, it works. Not only on soft tissue, but they are very effective on carpal fractures. »
"I have treated diabetics with peripheral neuropathy with LLLT and I really liked the results. »

Commercial communication QRI:
"Cody, a 14-year-old North Carolina boy with spastic cerebral palsy, experienced a significant improvement in movement, cognition and behavior with QRI™. For most of his life, one hand was clenched in a fist, and he could not straighten his arm. He was bent at the waist, unable to stand or sit upright, and suffered from nighttime back spasms. He couldn't straighten his legs and his toes were clenched. Cody was diagnosed with Oppositional Defiance Disorder, ADHD, autism, obsessive-compulsive disorder and is visually impaired.

After a session at QRI™, he was able to let go of the clenched hand and straighten his arm. Cody's parents had exhausted traditional therapies without seeing any improvement in the spasticity of his arm. After more sessions, he was able to sit up straight in his wheelchair and get up on a couch. He is able to stand up (with help) and is making good progress towards walking. His back spasms have almost disappeared, his feet can lie flat with less spasticity and he can straighten his legs. He is "jumping wheels" in his wheelchair. »

Scientific references

Transcranial Low-level Laser Therapy may Improve Alertness and Awareness in Traumatic Brain Injured Subjects with Severe Disorders of Consciousness: A Case Series
"The LLLT improved patients' alertness and awareness; seizures were potential side effects. Simulation-controlled studies, including quantitative assessment of awareness, should follow the case series. »

The Nuts and Bolts of Low-level Laser (Light) Therapy
"LLLT is also considered a viable treatment for serious neurological disorders such as head injuries, strokes, spinal cord injuries and degenerative diseases of the central nervous system.

Although head injuries are a serious health problem, the search for better treatments in recent years has not been successful. This has led to interest in more radical alternatives to existing procedures, such as lifelong learning. It is assumed that LLLT is beneficial in the treatment of myocardial infarction. In addition to its effects on increasing mitochondrial activity and activating transcription factors, LLLT may benefit TIA patients by inhibiting apoptosis, stimulating angiogenesis and increasing neurogenesis. Experiments with two mouse models indicated that LLLT may reduce the area of brain damage three days after treatment, and treatment with a 665 nm and 810 nm laser may result in a statistically significant difference in the Neurological Severity Score (NSS) of mice that had a weight that fell on the heads of exposed mice".

Role of Low-Level Laser Therapy in Neurorehabilitation
"...despite the efforts of 'big pharma', mistrust of pharmaceuticals is generally increasing due to uncertain efficacy and troublesome side effects. LLLT has no reported adverse events and no adverse events can be directly attributed to laser or light therapy. We believe that the high benefit/risk ratio of LLLT should be better appreciated by rehabilitation and physical medicine professionals. The introduction of affordable LED devices powered by rechargeable batteries will lead to many home applications of LLLT. The concept of "portable" LED devices is not far off. In addition, the particular benefits of LLLT for the central and peripheral nervous systems suggest that a much wider use of LLLT could or should be made in cases of brain disease and injury. »
