Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Direct application of digital modelling for personalized product design.
- +Addresses a significant user-centric aspect (aesthetics) in prosthetic development.
Limitations
The complexity of integrating advanced mechanical or electronic components into a custom-designed prosthetic shell can be a significant challenge.
Reliability & validity
The validity of the aesthetic mirroring is subjective but can be assessed through user feedback. The reliability of the CAD process depends on the software and the skill of the operator. The study's findings are specific to the transhumeral prosthetic context.
Think critically
Beyond aesthetic mirroring, what other user-centric design considerations are crucial when developing custom prosthetics, and how can digital modelling facilitate these?
Design Principles
"Form follows identity: Design elements should consider the user's psychological and social needs, not just functional requirements."
This approach addresses a common aesthetic concern in prosthetic design, moving beyond purely functional considerations to enhance user acceptance and psychological well-being. It demonstrates how digital modelling can bridge the gap between technical requirements and personal identity.
What This Means for Your Design
You can use a 3D scanner to copy one of your arms and then use computer software to make a mirrored design for a prosthetic arm that looks the same.

Paragraph starter
The research by Rhyne et al. (2017) demonstrates the potential of integrating 3D scanning and computer-aided design (CAD) to create aesthetically congruent transhumeral prosthetic designs. By capturing a 3D scan of the user's existing limb, designers can then utilize CAD software to mirror this form, resulting in a prosthetic that visually matches the natural anatomy. This approach not only addresses functional needs but also enhances user acceptance by considering personal identity and appearance.
