F-Scan^® System

in-shoe plantar pressure analysis

Paper-thin sensors placed inside footwear capture dynamic in-shoe pressure information unseen by the naked eye.

F-Scan Foot Pressure Mapping System Features:

In-shoe pressure and force information reveals interaction between foot and footwear
Quantifies force, contact pressure distribution, and timing (unlike traditional visual observation of foot function and gait)
Extremely thin, high resolution F-Scan sensor ensures the most accurate data is captured
Sensors trim to fit shoe size and a wide range of footwear (up to size 24E)
The F-Scan system is completely portable so data can be recorded in the office or in the field

Benefits of Plantar pressure analysis:

Manage treatment of foot inside the shoe
Enhance treatment outcomes
Improve orthotic footwear performance
Reduce costs by minimizing the need for follow-up and orthotic adjustments
Increase patient satisfaction and generate more referrals
Provide supporting documentation for fee-for-service approach and/or insurance claims
A comparison of gait, pre and post-treatment
Pressures and forces during gait displayed in time graphs
Position and trajectories for Center of Force (CoF) during stance phases of gait

User Experience:

"The F-Scan system has completely changed my understanding of the foot's function. I can now "see" how small changes in a custom orthotic device greatly affect foot function. I am able to make step-by-step changes and modifications to my patients' orthotics and know immediately whether it has bettered or worsened their condition. Because of my work with the F-Scan system, I enjoy my podiatric practice again. It is extremely fulfilling to help someone eliminate their limping gait and greatly decrease their pain." Bruce Williams, DPM, Merrillville, IN.

A Tekscan system consists of scanning electronics, software and patented thin-film sensors.

Every VersaTek based system uses specially designed scanning electronics called Cuffs. The Cuffs connect to the sensor, gather the data from the sensor, and then process and send this data to your computer via USB connection. VersaTek electronics sample at the fastest speeds and are compatible with other VersaTek sensors, giving you the ability to add in-shoe, prosthetic, grip, and seating & positioning capabilities to your Tekscan System.

F-Scan Pressure Sensors:

3000E- The standard in-shoe sensor used for most standard applications:

User Experience

"One power of the F-Scan system lies in the immediate and totally obvious visual feedback. Most cases are definitive even without referring to the staggering ability of the software to represent the data in any way you can think of. This simplicity combined with the fact that it is a foolproof means of pre- and post-testing treatment methodology makes this system invaluable to the clinician." Larry Pace, PTA, CSCS, USA Triathlon Coach, SATORI Physical Therapy & PACE Sports Training, Orange, CA
