FIGURE 1 Phase 1: Hanging weight pressures.

(A) (B)

(C) (D)

On each panel, the y-axis has the same scale and shows pressure exerted for controlled force applications. Panels show individual triplicate values
as separate symbols or as medians with bars indicating the minimum and maximum values. (A) Strap pressures with different clothing conditions
on thighs and models. The added hanging weights resulted in cumulative weights of 4.54, 9.08, 13.62, 18.16, 22.70, and 27.24kg. (B) Strap pres-
sures for Bare on each thigh and model. Rather than linear equations, the best fits for the indicated curves are one phase decay equations (preferred
curve fit for all conditions: Bare, Scrubs Skin, Scrubs Clothing, Uniform Skin, Uniform Clothing; p < .05, except for one Uniform Clothing p =
.095). Rather than a shared one phase decay, the best fit was different curves for each thigh and model and every condition (p < .0001, except two
models Bare p = .1294 for shared equation). (C) Strap pressures for Thigh 1 for all conditions. Rather than a shared equation, each clothing condi-
tion had a different one phase decay curve (p < .0001). (D) Strap pressures for Thigh 2 for all conditions. Rather than a shared equation, each cloth-
ing condition had a different one phase decay curve (p < .0001). The same was true for the remaining three thighs and both models (p < .0001).
