“…In a similar study, using 904 nm wavelength radiation to treat patients with chronic orofacial pain, Hansen et al [29] observed that, although on average pain reduction was not statistically significant, there was an increase in the urinary excretion of 5-HIAA in patients with reduced pain. A few years later, Laakso et al [30] observed decreased pain and increased levels of adrenocorticotropic hormone and β-endorphin following laser irradiation of myofascial trigger points in patients affected by neck and shoulder pain.…”

Over the past three decades, physicians have used laser sources for the management of different pain conditions obtaining controversial results that call for further investigations. In order to evaluate the pain relieving possibilities of photobiomodulation therapy (PBMT), we tested two near infrared (NIR) laser systems, with different power, against various kinds of persistent hyperalgesia animal models. In rats, articular pain was reproduced by the intra-articular injection of sodium monoiodoacetate (MIA) and complete Freund's adjuvant (CFA), while compressive neuropathy was modelled by the chronic constriction injury of the sciatic nerve (CCI). In MIA and CFA models, (NIR) laser (MLS-Mphi, ASA S.r.l., Vicenza, Italy) application was started 14 days after injury and was performed once a day for a total of 13 applications. In MIA-treated animals, the anti-hyperalgesic effect of laser began 5 min after treatment and vanished after 60 min. The subsequent applications evoked similar effects. In CFA-treated rats, laser efficacy started 5 min after treatment and disappeared after 180 min. In rats that underwent CCI, two treatment protocols with similar fluence but different power output were tested using a new experimental device called Multiwave Locked System laser (MLS-HPP). Treatments began 7 days after injury and were performed during 3 weeks for a total of 10 applications. Both protocols reduced mechanical hyperalgesia and hindlimb weight bearing alterations until 60 min after treatment with a higher efficacy recorded for the animals treated using the higher power output. In conclusion, this study supports laser therapy as a potential treatment for immediate relief of chronic articular or neuropathic pain.

“…It has been shown to be a low risk and safe treatment, but its true recovery of the conductive block or inhibit A-d and C fiber transmission [45,46]. It is possible that laser-induced neural blockade may then lead to a long-term alteration in nociception [47], analogous to the prolonged analgesia seen in some patients after the administration of local anesthetics [48] and changes at the endorphin level [49]. However, the neuromodulation effects of LLLT are dependent on many conditions in relation to timing and mode of irradiation and rarely have been observed for 904 nm laser sources.…”

Background: Cervical radiculopathy is a condition caused by the compression of the nerve root in cervical spine that commonly manifests as neck pain and it may also radiate from the neck into the distribution of the affected nerve root. There is a significant amount of evidence available to support the benefit of physical therapy and manual techniques in general for patients with neck pain with or without radicular symptoms.Objective: This study was conducted to assess the efficacy of Mulligan mobilization and low level laser therapy (LLLT) on pain intensity level, EMG dermatomal somatosensory evoked potential and functional level in patients with unilateral cervical radiculopathy. Materials and Methods:Fifty patients of both genders with diagnosis of unilateral cervical radiculopathy, their ages ranged from 40 to 55. They were randomly assigned into two groups; Group A: Patients received SNAGs Mulligan technique, in addition to conventional program. Group B: Patients received LLLT, in addition to conventional program. The treatment was conducted at a frequency of three sessions per week for four weeks.Results: Patients in both groups showed significant improvement post treatment in all the measured variables ; there was non-significant difference between two groups post-study in pain level where P-value was (0.128). There were no significant differences between two groups in amplitude, distal latency post-study, where P-values were (0.132) and (0.328) respectively. There were no significant differences between two groups in functional ability, where P-value was (0.156).Conclusion: Study concludes that both LLLT and SNAGs Mulligan techniques have shown positive results and are effective in improvements in pain intensity, EMG dermatomal somatosensory evoked potential and functional level among Patients with unilateral cervical radiculopathy.
