The Caplex™ System is an innovative clinical decision support tool that transforms how lower limb prosthetic feet are selected and prescribed. Designed for use in prosthetic and rehabilitation clinics, Caplex™ enables individuals with limb loss or limb difference to physically trial and compare the function of multiple prosthetic foot options—in real time, under their own bodyweight, and prior to prescription. This capability, previously unavailable in clinical practice, eliminates much of the guesswork that has long defined prosthetic foot selection.

At its core, Caplex™ combines programmable robotic hardware and intelligent control software to emulate the mechanical behavior of a wide range of commercially available prosthetic foot types. Users wear a modular emulator (resembling a prosthetic foot) that dynamically adjusts its mechanical response as the user walks. This allows both the patient and clinician to assess the feel, performance, and suitability of various options in real-world conditions, fostering informed, patient-centered decision-making.

Caplex™ is the first system to bring real-time prosthetic foot emulation into clinical environments. Traditional foot selection often relies on clinician familiarity, static data, or limited trials. Caplex™ introduces a novel approach: physical emulation over simulation, giving patients a mechanical “test drive” experience. This not only empowers users but also generates quantitative biomechanical and experiential data to support prior authorizations, justify medical necessity, and track long-term outcomes.

The system is modular and durable, constructed from both off-the-shelf and custom components—including actuators, load cells, embedded controllers, and cloud-integrated software. It is produced through a hybrid manufacturing process involving CNC machining, 3D printing, and small-batch electromechanical assembly. Designed for ease of use, portability, and repeated deployment, Caplex™ has already been adopted at over 37 academic and research institutions across the U.S., Canada, and Europe.

Caplex™ has been vetted through clinical studies conducted with the VA and leading rehabilitation centers, demonstrating its feasibility, safety, and clinical utility. Building on this foundation, the system is now being piloted in orthotics and prosthetics clinics to support real-world adoption and integration into routine patient care. Early clinical partners include VA hospitals, university medical systems, and private practices seeking to advance evidence-based prosthetic prescription. With over 500,000 individuals living with limb loss in the U.S. and more than 185,000 amputations annually, there is a clear and growing need for tools that improve prosthetic prescription. Caplex™ directly addresses this gap, reducing the risk of poor device matching, re-fittings, and dissatisfaction while improving functional outcomes and supporting reimbursement efforts.

As healthcare shifts toward value-based care, Caplex™ offers a scalable solution that is evidence-based, cost-effective, and person-centered. Its modular design and robust data capabilities also pave the way for future integration with electronic health records (EHRs), remote patient monitoring, and clinical outcome tracking platforms.

In summary, the Caplex™ System is not just a novel medical device—it is a platform for modernizing prosthetic care, enhancing clinical precision, and enabling patients to make informed decisions about their mobility and future.
