Is massage an effective intervention in the management of post-operative scarring? A scoping review

Background: Scar massage is a widely used treatment modality in hand therapy. This intervention is thoroughly discussed in the literature relating to burns rehabilitation, however, the evidence for its use in treating linear scars following surgery is limited. Purpose of study: To collate the empirical literature on scar massage for the treatment of postsurgical cutaneous scars. Study Design: Scoping review. Methods: Medline, EMBASE, CINAHL, AMED, Scopus, ProQuest Dissertations & Theses Global, and the Joanna Briggs Institute were searched from inception to December 2020. Two researchers used a data extraction tool to record key demographic, intervention and outcome data, and to apply the Oxford Levels of Evidence for each study. Results: Twenty-five studies met the inclusion criteria, reporting on a combined sample of 1515 participants. Only two papers addressed hand or wrist scars (92 participants). While all studies reported favorable outcomes for scar massage, there were 45 different outcome measures used and a propensity towards non-standardized assessment. Intervention protocols varied from a single session to three treatments daily for 6 months. The results from 13 studies were confounded by the implementation of additional rehabilitation interventions. Conclusions: The overall findings suggest that while there may be benefits to scar massage in reducing pain, increasing movement and improving scar characteristics; there is a lack of consistent research methods, intervention protocols and outcome measures. This scoping review highlights the heterogenous nature of research into scar massage following surgery and supports the need for further research to substantiate its use in the clinical setting.
