“…It was also demonstrated that type 1 metabotropic glutamate receptors decreased, and prostatic acid phosphatase and tubulin‐labeled varicosities were increased . Other studies have shown the involvement of the opioid and serotonergic systems in different pain models . However, further investigation is needed to elucidate the specific nuclei and subnuclei of the endogenous pain inhibitory system involved in this antinociceptive phenomenon.…”

“…In agreement with the results presented here, some researchers have demonstrated the antinociceptive effect of low‐level laser irradiation on the spinal cord in the same model used in our work but only starting from the 7th postoperative day. Data from the literature have demonstrated that endogenous substances encode the analgesic action of photobiomodulation in models of inflammatory and neuropathic pain.…”

Background There is a wide range of animal models available today for studying chronic pain associated with a variety of etiologies and an extensive list of clinical manifestations of peripheral neuropathies. Photobiomodulation is a new tool for the treatment of pain in a convenient, noninvasive way. Objective The aim of this work is to elucidate the effects of infrared light‐emitting diodes (LEDs) on behavioral responses to nociceptive stimuli in chronic pain models. Methods Forty‐eight Swiss male mice weighing 25 to 35 g were used. Two chronic pain models, ischemia‐reperfusion (IR) and spared spinal nerve injury, were performed and then treated with infrared LED irradiation (390 mW, 890 nm, 17.3 mW/cm2, 20.8 J/cm2, for 20 minutes). The behavioral tests used were a mechanical hypersensitivity test von Frey test) and a cold allodynia test (acetone test). Results The results showed that, in the IR model, the infrared LED had a significant effect on mechanical stimulation and cold allodynia on every day of treatment. In the spared nerve injury model, an analgesic effect was observed on every treatment day (when started on the 3rd and 7th days after the surgery). In both models, the effect was abolished when the treatment was interrupted. Conclusions These findings suggest that photobiomodulation therapy may be a useful adjunct treatment for chronic pain.

“…Based on research by Zhang et al, mast cell degranulation by laser irradiation is possible through transient receptor potential channels (TRPV2) [21]. Laser irradiation provides stimulation of mitochondria that stimulate mast cell degranulation, which stimulates the migration of T-lymphocytes capable of producing β-endorphins [22].…”

Musculoskeletal pain is a major cause of disability. Myofascial trigger points (MTrPs) in particular are a common source of pain in a substantial number of patients presenting at a pain clinic. Many different invasive and non-invasive forms have been advocated to the treatment of MTrPs. However, favourable outcome rates are inconsistent and some of these treatment forms described are often painful and have potentially dangerous side effects. Photomedicine including the coherent light sources (lasers) and more recently, non-coherent light sources have been reported to be beneficial in soft tissue lesions including MTrPs. Their beneficial therapeutic effects can be obtained without undesired effects. The main intentions of this chapter are to bring the attention of the doctors and physical therapists to the scientific approach of photomedicine, in particular laser therapy for the relief of pain arising from MTrPs, and to demonstrate how this type of therapy can be utilized in a rational manner for the relief of musculoskeletal pain. In addition, it has been found necessary to include or to start with an overview of the recently recognized diagnostic and therapeutic importance of MTrPs. Attention will therefore first be drawn mainly to incidence, types, aetiology, clinical diagnostic criteria and conventional forms of MTrPs.
