About

A hypertrophic scar is a serious health concern in the industrialized world. Two groups of patients were treated with standard medical care. The experimental group received additional laser therapy. scar assessment was measured immediately before treatment, after 3, and 7 months.

T test for comparison before-treatment between the control and study groups. ANOVA with repeated measures test for comparison among other measures.

Full description

Background: A hypertrophic scar is a serious health concern in the industrialized world. Objective: The impact of this study was to investigate the effect of the Nd-YAG laser at 532nm wavelength on hypertrophic scars. Patients and methods: Forty male and female patients with hypertrophic scars, ranging in age from fifteen to forty-five, were recruited from the burn patients' clinic within the Faculty of Physical Therapy, Cairo University, for this study. They were randomized into two equivalent groups. Group A (the control group) consisted of 20 patients who were given standard medical care, nursing, physiotherapy, and a sham laser during the course of treatment. In contrast, Group B (the study group) consisted of 20 patients who were given 532 nm laser radiation in addition to standard medical care, nursing, and physiotherapy. Treatment was conducted every 2 weeks for 14 sessions. Outcome measures included Vancouver Scar Scale score and scar volume. The assessment procedures were applied before the initiation of treatment (Pre), after 3 months (Post1) and after 7 months (Post 2) from the beginning of the treatment.
