Dr. Thiel has done in-depth research into low intensity laser therapy (LILT or LLLT) and has found many interesting articles from various sources. The general findings of each of these articles are outlined below.
T. Ebrahimi, et al.
Journal of Dentistry of Tehran University of Medical Sciences, published 2012 Autumn.
This article investigates the use of low intensity laser therapy to supply direct biostimulative light energy to the cells in an attempt to accelerate fracture healing. In addition, this study takes a look at 25 other relevant articles on the matter. This study found that low intensity laser therapy can accelerate bone healing by stimulating stem cells and osteoblastic activity.

The results of this study show that the use of laser could enhance callous development in the early stages of the healing process and therefore should be recommended as an additional treatment in non-union fractures in humans.

LILT increases the bone lamella density of compact bone and also increases the bone strength.

With a sample size of 100 individuals and being followed for three months, investigators found that each group had improvements to varying degrees. It appeared that a combination of ultrasound or LILT therapy with splinting was more effective than splinting alone in treating carpal tunnel syndrome.

Low Intensity Laser Therapy was effective in alleviating pain and symptoms and improving functional ability of the fingers and hand strength for mild to moderate carpal tunnel syndrome patients with no side effects.

Laser Therapy as a new conservative treatment is effective in treating carpal tunnel paresthesia and numbness and improved the subject’s power of hand grip and electrophysiological parameters.
Elwakil, T., et al.

Low Intensity Laser Therapy has proven to be an effective and non-invasive treatment modality for carpal tunnel syndrome, especially for mild to moderate cases when pain is the main presenting symptom.

Low Intensity Laser Therapy stimulated migration and fiber sprouting of neuronal cell aggregates, developed large size neurons with dense branches interconnected networks of neuronal fibers and therefore can be considered as potential procedure for cell therapy of neuronal injury or disease.
Neurosurgery Focus, Published 2009.
Using low intensity laser therapy accelerates and enhances axonal growth and regeneration after injury or a reconstructive peripheral nerve procedure. Laser activation of nerve cells, their growth, and axonal sprouting can be considered as potential treatment of neuronal injury.
Internal Review of Neurobiology, Published 2009.
The function of de-innervated muscle can be restored, not completely but to a very substantial degree by laser therapy treatments if initiated at an early state post injury. In peripheral nerve injury, laser treatment has an immediate protective effect by decreasing scar tissue and by decreasing degeneration in motor neurons. In addition it increases axonal growth and myelinization of the nerve. Laser irradiation accelerates migration, nerve cell growth, and fiber sprouting. Laser activation of nerve cells, their growth, and axonal sprouting can be considered as potential treatment for neural injury.
Rochkind, S., et al.

This study suggests that in patients with long term peripheral nerve injury, non-invasive laser phototherapy, or LILT, can progressively improve nerve function which leads to significant functional recovery.

The mitochondrial electron-transport chain has been shown to be photosensitive to red and near-infrared light. Although the underlying mechanisms have not been clearly elucidated, mitochondrial photo-stimulation has been shown to increase ATP production and cause transient increases in reactive oxygen species. However, LILT therapy was more advantageous and effective at lessening the symptoms of severity, pain alleviation, and increased patient satisfaction.
Chukuka, S., et al.

The conclusion of this study indicated that laser phototherapy is a highly effective therapeutic form of treatment for tissue repair and pain relief.
Henriques, A., et al.

Low Intensity Laser Therapy has been recognized as an anti-inflammatory and analgesic therapeutic modality. It has also been well established that it is effective in tissue repair. Low intensity laser therapy has a property that stimulates cell proliferation during wound healing.

This study demonstrates that Low Intensity Laser Therapy reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatments in patients with chronic neck pain.
Konstantinovic, L., et al.
Pain Medicine, Published August 2010.
This study investigated the clinical effects of low level laser therapy in patients with acute neck pain and radiculopathy. This study found that there were statistically significant differences with reduced pain to the arm and improved range of motion in the neck. This study clearly indicated that low level laser therapy gave more effective short term relief in arm pain and increased range of neck extension in patients with acute neck pain with radiculopathy when compared to a placebo group.

This study demonstrates that pain relief within the joint of those suffering from rheumatoid arthritis may involve a reduction in the level of pro-inflammatory cytokines and chemokines produced by the synovium. This mechanism illustrates the beneficial effects of Low Intensity Laser Therapy on other inflammatory conditions.
Hegedus, B., et al.

This study shows that Low Intensity Laser Therapy reduces pain and improves microcirculation of the area treated. In this study there was a significant improvement as far as reduction of pain, joint circumference, pressure sensitivity, and increased range of motion.

This study took place in the Physical Medicine and Rehabilitation School of Medicine in Turkey. Low energy lasers were widely used to treat a variety of musculoskeletal conditions including fibromyalgia. Forty female patients took part in this study. They were all diagnosed with fibromyalgia. This study demonstrated that laser therapy is effective on pain, muscle spasm, morning stiffness, and total tender point number in fibromyalgia and suggested that this therapy method is a safe and effective way to treat patients with fibromyalgia.

Laser photostimulation reported a greater value after surgical repair of ruptured and injured tendons for a better functional outcome and it can be applied safely and effectively in humans especially with respect to the proposed long term clinical outcome.

In this study global health status improved in patients who received low level laser therapy. There was significantly reduced pain and improved health status in patients with chronic joint disorders.
