By integrating sensor technology, designers can gather crucial data on performance and user interaction, paving the way for more refined and responsive prosthetics that improve quality of life and enable participation in activities previously considered inaccessible.

Key Finding

The study successfully created a custom 3D-printed prosthetic for cycling, which was equipped with sensors to gather performance data, highlighting the potential for enhanced sports participation while also identifying areas for future refinement.

Key Findings

• A personalized, 3D-printed upper limb prosthesis for cycling was successfully designed and prototyped.
• Integration of force and movement sensors allowed for data collection on prosthesis functionality during dynamic activities.
• Testing indicated areas for improvement in both mechanical and electrical aspects of the prototype.

Research Evidence

Aim: How can personalized, 3D-printed upper limb prosthetics with integrated sensors be developed and tested to facilitate sports participation for adult patients?

Method: Case study and experimental testing

Procedure: The process involved 3D scanning the patient's limb, semi-automated design using specialized software, and 3D printing the prosthesis. Force and movement sensors were integrated into the device, followed by laboratory and field testing, both with and without the patient, to collect functional data.

Context: Prosthetics design and assistive technology for sports

Design Principle

Personalization through advanced manufacturing and data-driven iteration leads to more effective assistive technologies.

How to Apply

When designing assistive devices, utilize patient-specific data (e.g., 3D scans) and consider incorporating sensors to monitor usage and inform future design iterations.

Limitations

The study focused on a single patient and a specific activity (cycling), and identified mechanical and electrical improvements needed for the prototype.
