Light Therapy Not Really Better for Diabetic Nerve Damage

According to a study reported in the medical journal Diabetes Care, a type of light therapy, which involves infrared light called monochromatic infrared energy (MIRE), is no more effective or better than sham therapy for treating nerve damage or neuropathy in people with diabetes.

Study researchers said that MIRE has been suggested to improve diabetic sensory neuropathy and prevent foot ulcers. To investigate the issue, Dr. Lawrence A. Lavery and colleagues from the Texas A & M University Health and Science Center College of Medicine in Temple assigned 69 patients with diabetes who have impaired vibration perception in their feet due
to neuropathy to either MIRE treatment or sham treatment for 40 minutes everyday at their homes for 90 days.

Results showed that there was no significant difference between the active and sham treatment in quality of life, vibration perception thresholds, or nerve conduction velocities. There was also a large placebo effect wherein those who got the sham treatment showed more improvement than those who underwent MIRE treatment.

“Overall, there was no statistical evidence that the anodyne treatment was effective in improving sensory perception compared with the sham treatment,” Dr. Lavery and colleagues report.
