Description

Introduction 
One challenge in providing solutions to any public health problem is the availability of reliable and robust data. Historically, the orthotics and prosthetics (O&P) industries have either ignored the collection of data all together, or have been sufficiently satisfied with collecting self reported information from patients during in office visits. While retrospective data collection has it merits (inexpensive, short duration, and smaller “n”), it is also subject to bias. Patients often feel pressure provide clinicians with answers that meet their expectations, instead of their true experiences or results. 

Background 
Digital health technology and wearable devices have been integrated into just about every single aspect of the healthcare community. From the casual use of FitBits and Apple watches to sophisticated ingestible devices for randomized clinical trials, adoption has skyrocketed. Prosthetics provide a natural platform for integrating digital health technologies, since amputees use their prosthetics daily to perform routine tasks. Innovative new designs that leverage technology and provide real-time feedback to the user and to their clinical team provide a platform for improved data collection and evaluation. 

Objective merits of the product 
The LIM Innovations SMART Prosthetic socket is a modular device consisting of a custom carbon-fiber frame, paired with a sophisticated textile dynamic tensioning system that contains an embedded set of electrical sensors and components. The technology facilitates measuring a number of functions giving the user a greater ability to monitor their health and communicates health status and metrics to their clinical provider. In this design, 5 sophisticated sensors push raw data to an interface that interprets, analyzes and displays relevant information in real time via an easily navigable smart phone app. Our design was built on stakeholder interviews and generative user research with amputees in a sprint format. 

Intended data users 
Amputees, researchers, and clinicians. 

Impact 
The adoption of digital health technology has been slow. In general 17% of Americans use mobile health tracking; 12% wearable technology. A critical factor in adoption is that historically, consumers or users have not been involved in the health-care decision-making process. Combine this with an industry where over 50% of amputees abandon their prosthetics due to lack of fit and comfort and the perfect environment exists for a technology driven prosthetics solution. Providing users with a simple solution to track daily health care metrics and real time information on residual limb health will improve management of health conditions. Pushing aggregate data to clinical or research teams provides large amounts of unbiased information for use in care or larger clinical studies. 

Andrew Pedtke, MD is the CEO and Co-founder of LIM Innovations. As a practicing orthopedic surgeon and visiting Assistant Professor at the University of California, Davis. Dr. Pedtke brings a critical vision to LIM Innovations and the industry as a whole through his background in the clinical utility of medical devices, outcomes based decision-making, cost-effective care and global health policy.

Dr. Pedtke has published and presented on technology that sits on the cutting edge of orthopedic surgery. Yet he balances this with insight into care models aimed to improve cost effectiveness in the setting of better clinical outcomes. Andrew’s entrepreneurial spirit seeks to evolve our advancement in the physical medicine space with solutions that have a true purpose or indication. “Function with Purpose;” says Dr. Pedtke, “reflects technology and/or care models for amputees and those with disability that meet the expectations of today’s health care system.” This perspective lays a solid foundation for LIM Innovations; a technology company with bold goals to greatly improve the human physical condition.

Andrew was an Echols scholar at University of Virginia majoring in International Health Care & Policy and completed medical school at the University of Minnesota. He finished his orthopedic surgery residency at the University of California, San Francisco in 2013.
