Infrared Light as Intervention to Improve Peripheral Sensation in an Individual Suffering from Peripheral Neuropathy: A Case Report

: We describe a treatment for patients suffering from peripheral neuropathy. Current treatment is focused on prevention of adverse outcomes, rather than addressing the associated circulatory and sensory deficits common to peripheral neuropathy. We describe the use of near-IR light to address the patient’s sensory loss, pain and lowered function. A 62 year old Caucasian male diagnosed as Type II diabetic was treated in this study. Using the Semmes Weinstein Monfilament Test, the Visual Analog Pain Scale and the Foot Function Index, he was found to have decreased foot sensation, pain and decreased lower extremity function. He received near-IR at 12 J/cm2 per treatment location, 3 times per week for 6 weeks. The light treatment was administered using a hand held probe over the lumbosacral spinal roots paravertebrally and on six locations on each foot. Post testing showed marked improvement in all three areas measured. These improvements were clinically significant based on the established minimally clinically important difference values for each of the three measures. The results suggest that near-IR energy may be an effective intervention to decrease pain, improve function, and increase sensation in individuals suffering from peripheral neuropathy. Basic research suggests that near-IR may increase blood flow. This result is believed to be achieved as a result of the relationship near-IR has with nitric oxide. Additional research is needed to establish the efficacy and generalizability of this treatment for patient populations similar to the patient represented in this case report.
