Abstract
Edema is a condition in which extracellular fluid accumulates excessively in the subcutaneous tissue, and the prevalence of lower limb edema is high in the elderly. There is a method called pitching test as a method to evaluate the condition of edema, but it is subjective scoring, and it is difficult to evaluate quantitatively. Therefore, the purpose of this study is to express the mechanical properties of edema using a viscoelastic model with the aim of quantitative evaluation of edema. In the pitting-test, compression is applied at a constant pressure for 10 seconds, and evaluation is performed using the depth of the indentation. In this study, we use a three-element viscoelastic model with two viscosity and one elasticity, which is also used to evaluate the viscoelasticity of the skin. The viscoelastic parameter is estimated by measuring the temporal change in displacement when pressure is applied to the edema using a laser displacement meter. By using the viscoelasticity parameter, it is considered that not only the indentation but also the return method will be different, and it may be possible to evaluate edema that could not be evaluated so far. In this paper, we report the measurement results using the edema phantom.
