Therapeutic effects of short-term monochromatic infrared energy therapy on patients with knee osteoarthritis: a double-blind, randomized, placebo-controlled study.

What the authors concluded

Short-term MIRE therapy provided no beneficial effects to body functions, activities, participation, and quality of life in patients with knee OA." Comment: Because of the biphasic dose response, this dose might have been too high. However, this isn't clear and should be investigated. Comment: The paper includes the same patient data as the other Hsieh 2012 paper (Arch Phys Med Rehabil). Comme

Devices that emit this wavelength

Matched on wavelength within 15nm, since LED bins vary by roughly that much and a tighter match would be false precision. Where we have an irradiance figure, the session length is the time needed to reach this study's dose of 83.2 J/cm² at that intensity.

Matching a wavelength is not the same as reproducing a trial. Session times assume the device's published irradiance is accurate at the distance it was measured, which on brand-claim figures is often optimistic. Where a device publishes both a peak and an average we use the average, and where it publishes a falloff curve we use the lowest figure, so these times run long rather than short. Clinical protocols also control for spot size, contact and skin type in ways a home device cannot.
