title: Do custom-fitted pressure garments provide adequate pressure?
abstract: Pressure garment therapy has become the worldwide standard of care for the prevention and treatment of hypertrophic scars. There are many reports in the literature on pressure garment therapy but few studies state the amount of pressure actually provided. The purpose of our study was to determine the amount of pressure applied to the scar/garment interface by custom-fitted pressure garments. The Iscan (Tekscan, Inc.) system was used to document scar/garment interface pressures of 144 new custom-fitted pressure garments. Average pressure readings for garments for the anterior thigh, anterior trunk, abdomen, buttocks, posterior trunk, posterior thigh, and arm were less than 22 mm Hg. Average pressure readings for the dorsal hand, leg, forearm, and dorsal foot were more than 28 mm Hg, with smaller relative standard deviations. The pressure readings varied greatly between garments in this group, frequently resulting in standard deviations that were higher than the pressure readings. The data show that despite precise fitting techniques, pressure garments do not provide a consistent amount of pressure at the scar/garment interface. This means that studies that report results of pressure therapy, but do not verify the amount of pressure applied, are of limited value. Precise determination of pressure "dose" must be made before the efficacy of pressure garment therapy can be determined objectively.
