Clinical effects of high-intensity laser therapy on patients with chronic refractory wounds: a randomised controlled trial

What the authors concluded

The BWAT scores significantly decreased in the treatment group compared with the control group at the end of 3-week treatment (difference=-3.6; 95% CI -6.3 to-0.8; p<0.01). Similarly, patients in treatment group showed a significant reduction of PUSH scores compared with the control group (difference=-5.3; 95% CI -8.1 to -2.6; p<0.01)."

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 80 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.
