Summary
This study validates geometric approximations for hand mass estimation in partial hand amputees. Findings aid in designing personalized prosthetic segments using palm dimensions.
Area of Science:
- Biomedical Engineering
- Anthropometry
- Prosthetics Design
Background:
- Accurate hand mass determination is crucial for prosthetic design.
- Existing methods may lack personalization for partial hand amputees.
- Geometric approximations offer a potential modeling solution.
Purpose of the Study:
- To validate cylindrical and parallelepiped approximations for hand mass modeling.
- To enable intuitive determination of missing hand segment dimensions and mass.
- To support personalized prosthetic segment design for amputees.
Main Methods:
- In-vivo hand mass measurements using Archimedes' water displacement method.
- Geometric modeling with cylindrical and parallelepiped approximations.
- Anthropometric investigation of segment dimensions relative to palm size.
Main Results:
