Surface electrical capacitance. (A and B) Skin hydration was measured by SEC probe in able-limb (AL, n = 4), transtibial (TT, n = 5), and transfemoral (TF, n = 5) participants while resting without a liner. Four sites of measure were acquired representing regions of low stress (site 1 TT, sites 2 and 4 TF) and high stress (sites 2, 3, 4 TT, sites 1 and 3 TF) for amputees. AL measurements were matched to TT sites. (C) Mean ± SE hydration (μS) for sites in AL, TT, and TF groups. (D) Mean ± SE hydration for all sites across groups. Dashed line represents mean value of AL without liner. *p < 0.05 versus AL, ^†✝p < 0.05 versus TT. SEC, surface electrical capacitance.
