F-Scan®
System
Bipedal In-Shoe Plantar Pressure/Force Measurement
The F-Scan system provides bipedal plantar pressure
and force measurements on the feet using paper-thin
reusable sensors placed in your client's shoes. The
system instantly detects, displays, and records plantar
pressures and forces without interfering with normal
gait pattern for the truest measurements available.
The quantitative information shown will enhance your
ability to evaluate, substantiate, and document your
diagnosis. With the F-Scan system, you get a view from
inside the shoe!

Applications:
- Screen for diabetic and other neuropathic
disorders
- Observe gait abnormalities
- Regulate weight bearing after surgery
- Monitor degenerative foot disorders
- Assess high pressures due to ray hypomobility
- Immediate determination of orthotic
efficiency
- Pre- and post-surgical evaluations
- Identify areas of potential ulceration
- Assess deviated Center of Force trajectories
due to pronation or supination
- Anticipate and alleviate pressure
on high risk areas
- Detect limb length discrepancies
The F-Scan system provides advanced, yet simple
to use software for stunning displays and informative graphs
that are instantly accessible, easy to read, and ready to
be interpreted. The test is quick and simple to perform, yet
provides plantar pressure distribution and forces through
all phases of gait. Used throughout the world, the F-Scan
system is the ideal tool for gait analysis and foot function
study.
System Oveview
Pre- and Post-Orthotic
Attempts to off load risk areas for ulcers with orthotics
in neuropathic feet is extremely difficult, risky, and time
consuming without an F-Scan. In this example, peak pressure
post-orthotic is shown to be high. A second modification will
then adjust the orthotic..
Software Features
- Dynamic 2-D and 3-D displays of real-time and recorded
data
- Displays of pressure and force curves over time
- View data frame by frame
- Side-by-side comparisons of pre- and post-treatment conditions
- Force-time integrals (Impulse)
- Frame by frame, single, and multi-stance phase displays
- Ability to isolate and analyze specific areas of plantar
foot
- Sharing (import and export) client movie files
- Display of Center of Force and its trajectory
- And much, much, more!

Multiple sensor options are available for your in-shoe
pressure measurements based on your application needs.
Add-On Options
Research Software- Software providing further analysis with
features including additional graphing capability, tools to
isolate and segment anatomical regions of the foot, and ASCII
output.
Video Synchronization™- Synchronize and play back both
video and pressure data simultaneously to review gait patterns.
TAM™ (Timing Analysis Module) - Software calculates
percentage timing data, with respect to segmented foot function
and phases of the gait cycle, and displays these relative
to normal function.
CoM'Nalysis (Center of Mass Analysis): Software calculates
and displays parameters for comparisons associated with the
behavior and performance of the body, center of mass, including
symmetry between left & right sides, purity, and energy
efficacy of gait.
F-Socket™ - Additional sensors and software for assessment
of in-socket pressure and force sensing capabilities for prosthetic
applications using your existing F-Scan electronics.
F-Mat™ or HR Mat™ - Adds a floor mat with pressure
and force sensing capabilities. HR Mat has a higher resolution.
Grip™ - Additional sensors and software for hand grip
and ergonomic studies. (Requires Research Software)
