The direct effect of photodynamic laser light are initially at the level of the epidermal neural network, but the effects move to nerves in subcutaneous tissues, sympathetic ganglia, and the neuromuscular junctions within muscles and nerve trunks.
Adenosine triphosphate (ATP) is the source of energy for all cells, and in neurons this ATP is synthesized by mitochondria while they are located in the dorsal root ganglion. These mitochondria are then transported along the cytoskeleton of the nerve by a monorail system of molecular motors. LLLT acts like an anesthetic agent, in that both LLLT and anesthetics have been shown to tempOrally disrupt the cytoskeleton for a matter of hours as evidenced by formation of reversible varicosities or beading along the axons, which in turn cause mitochondria to "pile up" where the cytoskeleton is disrupted.
The exact mechanism for this effect is unknown but it is not a thermal action.
It has been shown that LLLT at the correct dose decreases mitochondrial membrane potential (MMP) in DRG neurons and that ATP production is then reduced , so perhaps the lack of ATP could be cause of this neural blockade. The most immediate effect of nociceptor blockade is pain relief which occurs in a few minutes and has been shown by the timed onset of a conduction blockade in somatosensory-evoked potentials (SSEPs) . This inhibition of peripheral sensitization not only lowers the activation threshold of nerves but also decreases the release of pro inflammatory neuropeptides . In persistent pain disorders this reduction of tonic input to activated nociceptors and their synaptic connections, leads to a long-term down-regulation of second-order neurons . The modulation of neurotransmitters is a further possible mechanism of pain relief, as serotonin and endorphin levels have been shown to increase in animal models and following laser treatment of myofascial pain in patients . Thus LLLT can have short, medium and long term effects.

Abstract

Pain is the leading cause for medical consultations in the United States, with one in three Americans suffering from chronic pain each year. Musculoskeletal pain is the primary reason for absenteeism in work or school. Current treatment options include non-steroidal anti-inflammatory drugs (NSAIDs), steroid injections, opiates, and surgical interventions, each with their own associated risks. There is a need for effective pain treatments with lower risk profiles. For over four decades, low-level laser therapy (LLLT) and LED therapy (collectively known as photobiomodulation) have demonstrated their ability to reduce inflammation and edema, provide pain relief, and promote healing in various musculoskeletal conditions. This paper aims to review the use of LLLT for pain management, its biochemical mechanisms, dose-response curves, and its potential application by orthopedic surgeons to improve patient outcomes and minimize adverse events.

With the anticipated rise of chronic pain in developed nations, validating safe and cost-effective pain management techniques is crucial for enabling people to lead active and productive lives. Additionally, integrating LLLT, which is already utilized by many medical specialties worldwide, into the American healthcare system could offer patients more treatment options. A new, cost-effective pain therapy could enhance the quality of life while alleviating financial burdens.

For LLLT to be effective, specific irradiation parameters (including wavelength, power, power density, pulse parameters, energy density, total energy, and duration) must be met. The optimal penetrating wavelengths range from 650–850nm, potentially achieving a light density of 5mW/cm² at a depth of 5cm when the beam power is 1Watt and surface density is 5W/cm². LLLT targets four clinical areas:

1. The injury site to promote healing, remodeling, and reduce inflammation.

2. Lymph nodes to decrease edema and inflammation.

3. Nerves to provide analgesia.

4. Trigger points to alleviate tenderness and relax contracted muscle fibers.

Treatment durations per point typically range from 30 seconds to 1 minute. Simple cases may require treatment of only one point, while more complex issues, such as cervical or lumbar radiculopathy, may necessitate treatment of 10 to 15 points.

Conclusion

Realistic expectations must be maintained regarding LLLT's therapeutic use. Evidence supports that LLLT can effectively alleviate pain and accelerate the body's natural healing processes. It has a long history and substantial scientific backing for its role in pain management, with minimal side effects and good tolerance among the elderly. However, LLLT does not address structural deficits or instabilities in bone or soft tissue. It should be used as an adjunct therapy for pain relief, particularly in patients with neuropathic pain and neurological deficits. Successful outcomes depend on proficient clinical skills combined with an understanding of injury, inflammation, repair, pain mechanisms, and the effects of laser and LED therapy.
