Abstract:
Nineteen known area shapes simulated wounds and were measured using 3 methods and orientations (n = 57). Equivalence and accuracy were tested for ruler length × width and the WoundVision length × width and tracing functions. The WoundVision Coefficient of Individual Agreement value and accuracy were closest to the actual area (Psi_R = 0.77; 95% confidence interval, 0.528-1.016).
