In Vivo Evaluation of the Skin Tensile Strength by the Suction Method: Pilot Study Coping with Hysteresis and Creep Extension

Table 3

Progressive suction procedure performed with (w) and without (w/o) outer contention. Median and range value of hysteresis (arbitrary units) obtained with the two probe aperture diameters (AD 2 mm and AD 4 mm) on normal skin and connective tissue disorders.
