Effects of low-level laser therapy on bone healing and signs of pain in dogs following tibial plateau leveling osteotomy.

What the authors concluded

Results suggested that the LLLT protocol used had no beneficial effects on signs of pain or pelvic limb function following TPLO." "Those findings suggested that, for the dogs of this study, LLLT had detrimental effects or the control treatment (red LED light) had beneficial effects that exceeded those of the LLLT." Comment: The control group used also red light (from a LED light source), so the

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 1.5 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.
