    Area of Science:

    • Biomechanics
    • Biomaterials
    • Medical Device Design

    Background:

    • Sitting can cause mechanical stress exceeding tissue tolerance, leading to decubitus ulcers in vulnerable patients, like those with spinal cord injury.
    • Effective cushions can mitigate this risk by minimizing stress and gradients in soft tissues.

    Purpose of the Study:

    • To develop a physical model of the buttock-cushion system for aiding cushion design.
    • To evaluate the performance of various cushion materials in reducing tissue stress.

    Main Methods:

    • A 2D physical model using PVC gel (flesh) and a wooden core (ischium bone) was created.
    • Strain was measured using a grid on the gel and photographic analysis of deformation.
    • Finite strain theory and strain energy functions were used to calculate 'tissue stresses'.

    Main Results:

    • The study successfully modeled mechanical stress states in the buttock during sitting.
    • Performance comparison of five clinically used cushion materials was achieved based on stress reduction.
    • Identified high stress regimes within the model buttock under different cushion conditions.

    Conclusions:

    • The developed physical model serves as a valuable tool for buttock cushion design and evaluation.
    • This method allows for quantitative comparison of cushion materials' ability to reduce tissue stress.
    • Findings can inform the selection of cushions to prevent pressure ulcer formation.
