Docs /The platform

Prosthetic sockets have traditionally been designed by hand — a prosthetist sculpting a fit through direct experience with a patient, iterating in person. That process works, but it caps how much of the design space an individual practitioner can realistically explore for any one client, and it’s hard to make the resulting fit legible or repeatable as data.

Paralia’s platform takes the alternative path: design and fabrication driven by data, not manual sculpting. It starts from an accurate, structured understanding of how a patient’s own anatomy differs from a standardized target fit — computed directly from a 3D scan, not eyeballed — and makes that difference something a prosthetist can see, reason about, and design against.

That data-first foundation is what opens up a broader design space than sculpting alone allows: more room for engineering rigor, more room for personalization tuned to a specific client, and a design process that produces something reviewable and reproducible rather than a one-off physical object.

What it produces, concretely

Given a 3D scan of a patient’s residual limb, the platform computes exactly where and how much that limb’s surface deviates from a standardized target fit envelope, and renders that as a visual deviation map a clinician can inspect directly — not a black-box recommendation, but the underlying geometric picture a prosthetist can bring their own judgment to.

Status

The core platform is active and proprietary — it’s the thing the rest of the suite is built to test and support. See how it fits together for how parable, the open-source half of the suite, validates it against known ground truth.
