Community Prosthetic Fitting Initiative — Design Refinement Discussion

Hi engineers and contributors! 👋

We are coordinating a community prosthetic fitting initiative focused on improving open-source prosthetic designs for real-world community use. We'd like to convene a design refinement discussion with engineers, makers, and clinicians to align on:

Discussion Topics

1. Parameterization & Personalization — How can CAD files and parametric models be improved to better accommodate diverse patient anatomy? (Reference: OpenBionics' anthropometric-based design approach)
2. Material & Fabrication — Optimizing for off-the-shelf materials and 3D printing workflows; cost reduction targets
3. Electrical & Actuation — Myoelectric control integration, servo motor selection, and battery life improvements
4. Clinical Validation — How to bridge the gap between open-source prototyping and clinical trial evidence (see trends below)
5. Accessibility & Usability — Simplifying assembly guides for community makers and non-engineer volunteers

Current Clinical Trial Landscape (from recent data)

• Sponsor activity: VA healthcare systems and academic medical centers are actively sponsoring prosthetic-related studies, primarily at Phase NA (device/post-market studies)
• Key focus areas: Limb-sparing surgery alignment, thermoregulation in prosthetic sockets, AI-driven prosthetic control
• Gap identified: A clear need for community-engaged design refinement that feeds into clinical validation pathways

Proposed Community Fitting Event Location

📍 Central meeting point for Boston/Cambridge/Somerville volunteers:
Harvard Square / Central Square area, Cambridge, MA — wheelchair accessible via Red Line (Harvard Station, confirmed wheelchair-accessible). Nearby: Cambridge Public Library (main branch) for indoor meeting space.

Next Steps

• 👀 Interested engineers: Leave a reaction + comment with your expertise area
• 📅 Proposed meeting: Community fitting event at the Cambridge/Somerville border area
• 📋 Action items: CAD parameterization review, fabrication workflow standardization, clinical data collection protocol
