Data-Driven Prosthetic Socket Fit with Matt Wernke, PhD
Socket comfort is still the problem that won’t go away, and “good hands” can only take you so far when patients need consistency, speed, and healthier tissue loading. We sit down with Matt Wernke, Director of Research and Development at WillowWood , to talk about what changes when prosthetic socket design becomes measurable and repeatable instead of mostly interpretive. Matt walks us through the real origin story: a Department of Defense funded clinical trial built to answer a blunt question, how should we distribute pressure on a residual limb in a way that protects skin health and reduces tissue injury? That research led to TIG, a handheld tool designed to quantify tissue stiffness, basically turning what clinicians already feel during palpation into data that can be used in a digital workflow. We talk outcomes, iteration, and why proving what you deliver matters as much as the design you intended. From there we get into the modern workflow: TIG measurements feeding into WillowWood’s revamped Omega platform, AI-assisted mapping of measurement sites onto a scan, and a socket recommendation the clinician can verify and personalize. We also dig into the practical benefits clinics actually care about, fewer disruptions for patients, stronger documentation over time, and the long-term roadmap of monitoring fit changes and even automatic adjustment at the interface. Along the way, we touch on how WillowWood uses 3D printing for prototyping, components, fixtures, and safety, plus a candid look at adoption and the fear of “replacing” craft instead of enhancing it.
