Steep suction procedure. Median values of parameters defining the creep extension in the repeat stress-versus-time recording modality (3 and 5 cycles) for different probe aperture diameters (AD 2 mm and AD 4 mm) using a 500 mbar depression for 5 s performed with (w) and without (w/o) outer contention on normal skin and connective tissue disorders. The differences in maximum deformation after 3 and 5 cycles (ΔMD3, and ΔMD5, and the corresponding residual deformations (ΔRD3 and ΔRD5) were recorded.
