Application of Green LED Exposure for Treatment of Neuropathic Pain

Followed by cancer, diabetes is the most common symptom for neuropathic pain. Owing to prevalence of the painful diabetic neuropathy (16%) among the elderly population around the world suffering from diabetes, the global neuropathic pain market is likely to gain an uptick in the near future. Factors driving the global neuropathic pain market include novel treatment options approval for neuropathic pain, soaring demand for neuropathic pain treatment, growing number of pain management centers and increasing prevalence of cancer & diabetes. Patient awareness on neuropathic pain treatment, increasing demand for generic drugs and rapid product launches for neuropathic pain treatment are some trends observed in the global neuropathic pain market.

Global Neuropathic Pain Market to Witness 5.6% CAGR During 2016 to 2026

Reinforced healthcare infrastructure & well-established reimbursements are fuelling the growth of neuropathic pain market across the globe. Pharmaceutical companies are concentrating on improved drugs development for fulfilling unmet patient needs those suffering from neuropathic pain. The global neuropathic pain market was worth US $5200 million in 2015 and it is estimated to witness 5.6% CAGR during 2016 to 2024 according to the report by Persistence Market Research (PMR).

Green LED Exposure for Treatment of Neuropathic Pain

In the United States, more than 100 million people suffer from chronic pain which diminishes their productivity and quality of life, costing billions of dollars per year to manage medically. This has shattered emotional wellbeing of people and has resulted into suicides & accidental drug overdoses. However, researchers from University of Arizona have come up with a non-pharmacological approach for managing chronic pain by treating it with green LED (light-emitting diodes). The results of this study have appeared in the February 2017 edition of Journal Pain. The study reflects that rats prone to neuropathic pain bathed in green LED depicted more tolerance for tactile & thermal stimulus as compared to rats not bathed in green LED. While, in both cases, zero side-effects were observed and no visual or motor performance was impaired.

For receiving green LED exposure, one group of rats was placed in clear plastic containers affixed with green light-emitting diode strips allowing the rats to bathe in green light. Second group of rats was exposed to room light fitted with contact lenses allowing green spectrum wavelength to pass through. Both of these groups were benefitted by green LED exposure. However, a group of rats fitted with opaque contact lenses that blocked green light didn’t benefit from green LED exposure. The researchers are currently focusing on a clinical trial with the help of green LED therapy for people suffering from fibromyalgia (chronic pain’s common source).

Treatment of Severe Neuropathic Pain, If Ignored, Results into Permanent Nerve Damage

Tissues possess a nerve supply. When nerves are performing well, signals are sent from them which we interpret as pain. Neuropathic pain involves compression or irritation of the nerve and the nerve is injured. This results in nerves sending incorrect signals to remaining pain centres. This could possibly result in nerve function change at both site of injury as well as areas around injury. Treatment of mild nerve pain may be ignored but severe nerve pain, if ignored, may cause permanent nerve injuries. Prevention of nerve pain depends on the condition of pain. Some can be prevented by avoiding lifting of excessive weights while some can’t be prevented as they are associated with familial or genetic cause. The probability of patient suffering from nerve injury to regain the condition before the injury solemnly depends on severity of condition and the intensity of treatment’s effect. Generally it takes six weeks for the patients to recover from nerve injury. If the neuropathic pain persists, then for managing the pain, surgery is needed involving procedures for decompressing the nerve such as removing nerve injury source.
