Mesure des changements temporels de la couleur de la contusion à l'aide d'un colorimètre
Purpose: To explore the pattern of skin color change of contusion and to find suitable indicators to infer the time of contusion formation and initial degree. Methods Using negative pressure suction, areas of skin contusion of different degrees were simulated bilaterally on the medial forearms of 41 volunteers. Measurements were made using a colorimeter every 0.5 d for the first 3 d after the injury and every 1 d after 3 d until the color difference in the contused area was indistinguishable to the naked eye. Curve fitting was performed for the six color difference indicators ΔL*, Δa*, Δb*, ΔE*ab, […]
