Effect of photobiomodulation on femoral fracture specimens in rats with experimentally induced osteoporosis

What the authors concluded

The microtomographic analysis showed no differences between the groups analyzed in any experimental period (p > 0.05). Histometric analysis showed a greater area of newly formed bone for the PBM group compared to the WPBM group (p < 0.05), corroborating the immunohistochemical result, which shows greater labeling of TGF-B and VEGF.

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 212 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.
