Devices that deliver monochromatic infrared
energy (MIRE) did not fare any better in reducing
foot numbness in individuals with nerve damage
due to diabetes, compared with placebo treatments.
During the 8-week study, 39 adults with
diabetic peripheral neuropathy were randomly
treated with MIRE or placebo therapy applied 3
days per week for 4 weeks.
Reporting in Diabetes Care (December 2005),
the research team found that 30 minutes of MIRE
therapy was not more effective in improving sensation
on the sole of the foot, compared with the
placebo treatment. MIRE devices were approved
by the FDA in the mid-1990s to enhance circulation
and reduce pain. The devices have been used
in patients with wounds and soft-tissue trauma.
