Numerical simulation of pressure therapy glove by using Finite Element Method

Area of Science:

• Biomedical Engineering
• Materials Science
• Biomechanics

Background:

• Pressure therapy garments are crucial for managing hypertrophic scars post-burn.
• Accurate pressure application is vital for treatment efficacy and patient adherence.
• Quantifying pressure distribution from garments, especially gloves, is challenging.

Purpose of the Study:

• To develop and validate a biomechanical model for simulating pressure distribution from a pressure glove on the hand.
• To utilize finite element analysis (FEA) for predicting pressure magnitudes and distribution.
• To provide insights for optimizing pressure garment design and understanding scar treatment mechanisms.

Main Methods:

• Developed a finite element model incorporating 3D hand geometry (from laser scanning) and glove material properties.
• Modeled the glove as an isotropic elastic shell and the hand as a homogeneous, isotropic, linearly elastic body.
• Simulated the glove wearing process to obtain contact pressure between the hand and glove fabric.

Main Results:

• The FEA model successfully simulated pressure distribution on the hand dorsum.
• Validated simulation results showed good agreement with experimental interface pressure measurements.
• The model allows visualization of pressure distribution, aiding design and analysis.

Conclusions:

• The developed biomechanical model is a reliable tool for predicting pressure distribution from therapy gloves.
• This simulation can inform the optimization of material properties and design of pressure garments.
• The findings contribute to understanding pressure therapy mechanisms for hypertrophic scars and improving garment functionality.
