Adjuvant visible incoherent polarised phototherapy in chronic skin defects: a single-arm prospective observational cohort study

What the authors concluded

Positive healing dynamics were recorded in 92% of the cohort and complete defect closure in 52% (n = 26). In the chronic-pain subgroup (n = 17), pain was reduced in 12 patients and resolved in 5. Improvement was associated with the principal clinical problem (χ2 = 10.406; df = 3; p = 0.015) and with therapy duration (χ2 = 8.630; df = 3; p = 0.035). Two patients reported mild, transient local r

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 1.8 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.
