Effects of Low-Power Light Therapy on the Tissue Repair Process of Chronic Wounds in Diabetic Feet.

What the authors concluded

The Laser Group presented a significant increase of the tissue repair index when compared with the Control Group, with a significant statistical difference (p < 0.013). There was no significant difference between the groups in all the weeks using the PUSH scale." Comment: Strangely the figures seem to show a large difference in PUSH scores between the groups but the abstract says there is no sig

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 6 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.
