Instant Analysis of Socket Forces

Art and Science: Precisely Aligned
The way a prosthesis fits the amputee’s residual limb is key to optimal prosthesis function and limb health.

Until now, clinicians fit prostheses through trial and error, without the benefit of objective, scientific feedback. This commonly resulted in the prosthetic socket applying dangerous or unbalanced forces to the residual limb that could lead to skin and joint trauma as well as repeated socket replacement.

With Compas™, prosthetists can use instant, real-time measurements of socket forces to optimize prosthesis fit and improve limb health for each individual.

Compas™…Transforming the Fitting Process
Compas™ hardware and software work automatically with Orthocare Innovations’ Smart Pyramid™ to extract and interpret socket-force data, instantly providing objective kinetic measurements of the forces the socket is applying to the amputee’s residual limb.

It also provides direct advice for adjusting componentry to obtain optimum fit. This advice builds on a database of thousands of amputee patient records and decades of expert patient care experience.

Compas™ is designed for everyday use by prosthetists, without the need for gait labs or specially trained staff. The Smart Pyramid™, with its embedded sensors, is integrated into the prosthesis and continuously measures the dynamic forces applied to an amputee’s residual limb during walking in real-life settings. Smart Pyramid’s™ data is captured by Compas™ and transmitted to your computer wirelessly via Bluetooth, where it is displayed with vivid graphics and clear analytics.

Scientific Analysis of the Art of Fitting a Prosthesis
During Smart Pyramid’s™ development, Orthocare Innovations researchers worked with patients to collect data from precisely controlled changes in the spatial relationship of the prosthetic foot relative to the socket. This simulated the range of adjustability that is normally seen in clinical settings. Our researchers then analyzed this data to determine, statistically, how those changes were related to socket-reaction forces. They developed an advanced computer model that detects when these socket-reaction forces are anything less than ideal. This technology then does the extraordinary—it recommends changes to prosthetic components that can reduce or eliminate injurious socket forces.

Revolutionary technology. Remarkably easy to use

Ease of Use
The Smart Pyramid™ looks like an industry-standard prosthetic pyramid, with the familiar European four-hole attachment configuration. Mounted just distal to the socket, it is easy to integrate into any endoskeletal lower-limb prosthesis and remains for the life of the limb. It requires no batteries or servicing, and is sealed against moisture penetration.

To enable gait analysis, the Compas™ Master unit clicks onto the Smart Pyramid™ to communicate with your computer and to provide power, microprocessor control, motion sensing, and a laser guide. The system continuously measures dynamic forces and balance while the patient is standing or walking, indoors or outside, on any terrain.

Precision from the Inside Out Compas™ is based on direct measurement of socket-reaction forces using a sophisticated electronic instrument integrated within a Smart Pyramid™ adaptor attached near the base of the socket. Our extensive research has measured precisely how these forces change with alterations to the spatial relationship of components relative to the socket.

Time-Saving Simplicity
Compas™ and Smart Pyramid™ eliminate the need for time-consuming, repetitive changes to prosthetic components and saves time during the initial fitting. This reduces the time the amputee spends in the clinic and frees the clinician to serve other patients.

Amputees also feel the benefits of the Compas™ and Smart Pyramid™ throughout the fitting process and gain confidence from seeing the objective information about what they feel. Then, they go back to their lives with an optimally fitted socket, gaining confidence with every step they take.
