Current Physical Therapy for Skin Scar Management: A Scoping Review

Background: Scar impairments impose a significant economic burden and negatively impact an individual's well-being and quality of life. However, there is a lack of standardization in physical therapy interventions for scar management. Objective: This study aimed to provide a comprehensive overview of studies addressing non-invasive physical therapy interventions for scar management. Methods: This scoping review was conducted following the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis. Six databases were searched, and additional studies were retrieved through gray literature and the reference lists of included articles. All studies considering non-invasive physical therapy interventions for scar management were included. No restrictions were applied regarding time, context or publication type. Results were illustrated using descriptive statistics and summarized in an infographic. Results: Out of 13,419 initial records, 92 studies met the inclusion criteria. Most articles were narrative reviews (n = 41) followed by randomized controlled trials (RCT) (n = 18). The most reported interventions were pressure therapy (n = 41), physical therapy modalities (n = 37), silicone-based products (n = 29) and massage (n = 20). Conclusions: Scar management involves a wide range of physical interventions. However, research has predominantly focused on adults, particularly those with burns, with limited attention given to pediatric or non-adult populations. Furthermore, there is significant variability in the application parameters, scar localization and size. Examining the included study designs, most of the research presented reduced sample sizes and lacked control groups. Notably, almost half of the studies were based on expert opinions. Future high-quality research is needed to identify evidence-based interventions for the clinical management of scars.
