Effect of orange polarized light on post burn pediatric scar: a single blind randomized clinical trial.

The study included only 30 children from a single outpatient clinic, and it used a convenience sample. It lasted only four weeks and had no follow-up, so long-term scar outcomes are unknown. It assessed only the Vancouver Scar Scale, a subjective scar rating, and did not measure functional activity, muscle strength, or patient or parent perception. The same experienced physical therapist delivered the interventions and assessments, and the paper does not state that participants or the therapist were blinded. The light group received standard scar management plus medical color polarized light and orange filtered polarized light, so the contribution of any single component cannot be separated. It studied only wrist and hand scars in children aged 3 to 7 years with hypertrophic scars at least two months after healing, and it excluded children with keloid scarring or concomitant skin disease.

The authors declared no conflicts of interest. The supplied text does not report who funded the study.

Do not conclude that orange filtered polarized light alone treats pediatric burn scars. The light group also received pulsed ultrasound, deep friction massage, range-of-motion exercises, and medical color polarized light before the orange filter. The trial lasted four weeks, had no follow-up, and used a subjective scar score, so lasting benefit and independent effect are not established.
