NEW YORK (Reuters Health) - A type of light therapy involving infrared
energy is no more effective than sham therapy for treating nerve
damage, or neuropathy, in people with diabetes, according to a study
reported in the medical journal Diabetes Care.

"Monochromatic infrared energy (MIRE) has been suggested to improve
diabetic sensory neuropathy and even to prevent foot ulcers," write
Dr. Lawrence A. Lavery and colleagues from Texas A&M University Health
and Science Center College of Medicine in Temple.

To investigate, they assigned 69 diabetic subjects with impaired
vibration perception in their feet because of neuropathy to either
active MIRE treatment or sham treatment, using the light units
provided for 40 minutes every day at home for 90 days.

After that time, the researchers found that there were no significant
differences between the active and sham treatment groups in measures
of quality of life, vibration perception thresholds, or nerve
conduction velocities.

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