Objective measurement of burn scar response to treatment is important to facilitate individual patient care, research, and service development. This work examines the validity and reliability of the tonometer as a means of quantifying scar pliability. Ten burn survivors were recruited into the study. Triplicate measures were taken for each of four scar and one normal skin point. The pliability score from the Vancouver Scar Scale also was used as a comparison. The tonometer demonstrated a high degree of reliability (intraclass correlation coefficients 0.91-0.94). It also was shown to provide a valid measure of pliability by quantifying decreased tissue deformation for scar (2.04 +/- 0.45 mm) compared with normal tissue (3.02 +/- 0.92 mm; t = 4.28, P = .004) and a moderate correlation with Vancouver Scar Scale scores. The tissue tonometer provides a repeatable, objective index of burn scar pliability. Using the methods described, it is a simple, clinically useful technique for monitoring an individual's scar.
