INTRODUCTION
This manual describes how to use Tekscan’s Presto-Scan Pressure Assessment System. Presto-Scan is a reliable and
easy-to-use system that enables you to capture foot strikes, review dynamic weight transfer and view local pressure
concentrations. The system senses the dynamic barefoot pressures as they are happening (in real time), presents the
information as a vivid color-coded display, and allows you to record the information (as a ‘movie’) for review. The
Presto-Scan system also comes with a full-featured client file management system, which makes storing client records
and tracking pressure recordings simple.
The Presto-Scan system is comprised of the Microsoft (MS) Windows -based Presto-Scan software, the associated
hardware, and patented Tekscan sensors. The system’s versatility allows you to record various types of plantar pressure
information, manipulate it for analysis, and print this information to any Windows-compatible color or grayscale
printer.
This manual provides a thorough description of all of the system’s capabilities. Follow the Quick Start section as a
guideline, and refer to specific sections for more detailed instructions on how to use each feature.

QUICK START
This section is a quick look at how to use your Presto-Scan system. This Quick Start procedure should be followed as
a general outline; it will give you the basics on how to view sensor data in a Real-time window, record this data, play the
recording back, and analyze the pressure information. However, you must read the entire manual before performing
any tests. Familiarity with MS Windows is assumed.
Note: You must read the entire manual before performing any tests, as this only provides general
guidelines.
Note: Familiarity with MS Windows is assumed.
Note: This procedure assumes that the proper hardware and software has been successfully
installed on your system (refer to the “Installation” section).
Before performing the Quick Start steps, and after each subject’s use, it is important to fully sanitize and disinfect the
sensor cover/housing, making sure to wipe it with an Alcohol-based solution. To do this, slightly dampen a cloth with
the alcohol solution, careful not to soak or saturate the cloth. Then wipe the sensor cover/housing, and any other
system component that has come in contact with the subject.
You are now ready to follow the Quick Start procedure below:
1. Make sure the sensor tab is inserted correctly into the handle. Place the mat sensor on a hard floor surface.
Placing the mat on a soft carpet may adversely affect your pressure readings. For further information, see
Inserting a Sensor into the Handle.
2. Click on the ‘Start’ button at the bottom left of the screen, select Programs, then click the
Presto-Scan icon to run the program.
3. The Balance window will be visible, as well as the Legend and Sample Pressures. If there is no sensor in the
handle, you will be prompted to ‘Please insert a sensor into the handle.’ In this case, insert the sensor and
close the handle latch.

5. If this is a returning client, click the Open Client button. Select the client, and click the Open Client button at
the bottom of the "Clients" dialog. You will be taken to the Client Record dialog box. From this dialog, you can
select either Walk Mode or Balance Mode. For now, click the Balance Mode button at the bottom of the dialog
box. Alternately, you may also have your client simply step onto the sensor and begin the analysis without going
through the Client Record at all.
6. The client’s color-coded plantar pressures should be displayed in the Balance Window. Adjust the legend until
you achieve a good color distribution on the client’s pressures. Adjust the division lines as necessary to get a
good equilibrium between left and right pressures, as well as front and back pressures.
7. Use one or more of the following View menu options to enhance your Real-time display:
•2-D Contours (default)
•3-D Contours
01/04/07

Refer to the Main Menu section for a full description of each item.
Hint: The 3-D Contours display is essential in finding higher risk pressure areas. As you can see in the example
below, the 3-D display shows the higher pressure sites as peaks, enabling you to compare areas that may be the
same color in the 2-D display.
2-D Contours View
3-D Contours View
8. Record a Balance or Walk movie. To record a Balance movie, click the Record Balance button if not already in
a Balance window. Have the client step onto the sensor. Click the snapshot button to record a single frame, or
click the record button to record several frames while the client rocks or shifts his or her weight.

Have the client turn around and walk across the mat, placing the right foot on the mat.
When recording is
completed, both
foot strikes will be
displayed in Peak
mode.
9. Review the
movie. Click the Peak button to
turn Peak mode off and view foot
strikes as they occurred (see image
at left). Click the Play Speed button
to adjust the speed of movie
playback.

HARDWARE & INSTALLATION
The software, along with your Presto-Scan hardware, is a complete Tekscan system. The hardware collects plantar
pressure data from the sensor and makes that information available to the software. Each sensor is sampled as your
subject walks, runs, jumps or stands on the sensor. The software allows you to view the collected sensor pressure data
as it happens (in real time), record this information as a "movie", and review and analyze it at a later time.
This section presents instructions for hardware installation, and also provides the system requirements necessary to
support the Presto-Scan pressure measurement system.

Note: The Tekscan Parallel Interface Module may not work with all Printers. If an incompatibility
occurs, Tekscan recommends you connect the Parallel cable from the Parallel Interface Module to
the Computer’s Parallel Port, and connect your printer to the Computer’s USB port directly (a
“Parallel to USB” adapter may be required to connect your Printer).
As another option, you can upgrade your existing hardware to the new USB Handle, which directly
connects to your computer’s USB port.

Main Window
When you initiate the Presto-Scan software program, the Main Window is displayed on your computer screen. The
Main Window consists
of the Menu Bar,
Toolbar, and Main Status
Bar, as well as a Balance
Window, or Walk
Window. A Pressure
Legend and three
sample foot pressures
are also shown. The
window that is selected is
considered the active
window. Only one
window can be active at
one time, and the Title
Bars of the other
windows will be grayed
out. The Main Window
is shown in the figure
below.

Title Bars
Each window (Walk Window, Balance Window, and main Program Window) has a Title Bar along the top, which
displays the name (title) of that window (e.g. "Presto-Scan DB" or "Movie1.fsx" or "Left (Rec)"). If that window is
paused, "(Paused)" is added to the title. If a recording is in progress, "(Rec)" is added to the title. Each Title Bar has
the usual MS Windows control button at the left end and minimize, maximize and close buttons at the right end. Only
one window may be active at one time; the active window’s Title Bar will be highlighted (usually in blue), while the
deactivated windows’ title bars will usually be gray.
The following displays the left side of the Main Program Title Bar:
The following displays two pre-recorded Walk Movies (Left and Right feet). The Left movie is grayed out (inactive),
while the Right movie is highlighted (active):
The following shows a Walk Window Title Bar while recording is in progress:
Menu Bar
The Menu Bar provides the pull-down menus used to control the Presto-Scan program. Each Menu Bar option is
described in detail in the Main Menu section. When no Movie windows are open, the Menu Bar contains only the File,
Options, and Help menus.
When a window is open, the other menus become available (see figure below).
When a Menu Bar item is unavailable, it will be grayed out.
Toolbar
Most Presto-Scan functions can be performed using the Toolbar. The Toolbar provides the same options as the Menu
Bar, but with icons replacing pull-down menus. Each icon on the Toolbar has a corresponding pull-down item in the
Menu Bar; however, only the most frequently used items on the Menu Bar have an icon on the Toolbar.
Note that not all Toolbar functions are available at all times. When a function is unavailable, it will be
grayed out.
The two levels of the Toolbar can be relocated (separately) in the Main Window by placing the cursor anywhere on one
of them (not on an icon) and dragging. If you place the cursor on an edge of the Toolbar, a two- or four-way arrow will
appear, and its shape and size can be changed. The Toolbar icons are shown below.
The following shows the toolbar when seen in "Display Mode ":

The following shows the toolbar when seen in "Documentation Mode":
The following diagram explains all the tools found on the Toolbar:
Status Bars
There are two Status Bars located within the software. The Main Status Bar is located at the bottom of the software
window, and provides information about what is happening on your screen at any given moment. When the cursor is
over a Toolbar icon, the left side of the status bar will give a description of that icon; otherwise, it will say "Ready."
The second Status Bar is located at the bottom of the Balance or Walk Windows and will indicate whether the sensor is
functioning properly by displaying "Sensor OK". If the sensor is not situated properly within the handle, or is not
functioning properly, the Status Bar will display the following: "MISALIGNED!" The following diagram illustrates both of
these status bars and where they are located:
In the image at right, the Sensor is not aligned properly within the Sensor Handle:
Within the Walk Window, the Status Bar also indicates the
number of frames that will be recorded. This will help you
keep track of what is going on during a recording, and for
timing purposes.

Input Bar
For both Balance and Walk recordings, there is an input bar that runs along the bottom of the main program, just above
the Main Status Bar. This is where the user can input a variety of information about the subject and proper footwear.
The image below displays this input bar:
The information that is entered here will also appear when the File -> Print option is used to create a subject's
printout.
Balance Window
The Balance Window displays the sensor’s color-coded
pressure information as it is happening. If no pressure is
on the sensor, a blank balance window will appear. A
balance window is opened by default when the software
is launched. When in Walk mode, click the Balance icon
in the Toolbar to return to the balance window.
Note: When your computer screen display is set to
"Screen Saver" mode, stepping on the sensor, pressing
a key on the keyboard, or moving the mouse will
automatically bring the Presto-Scan display back to
"Balance Mode". This will greatly reduce the amount of
operations that need to be performed in order to take a
recording.
Walk Window
The Walk Window allows you to record one left foot strike and one
right foot strike. To open this window, click the Record Walk button on
the Toolbar. The software guides the user through recording first the
left and then the right footstep. Center of Force is shown by the red and
white symbol. Once both foot strikes have been recorded, the window
defaults to showing peak pressure for both feet. Clicking the Peak
button to turn Peak off can play foot strikes.
Pressure Legend
The Pressure Legend shows the pressure range that
corresponds to each of the 13 possible colors in any
open Balance or Walk window. Lower pressures are
indicated by cooler colors, where blue is the lowest
pressure. Higher pressures are represented by hot
colors, with red representing the highest pressures.
Clicking the triangle on the right side of the color scale
and dragging it upwards or downwards can change the
pressure range represented by each color in the legend. This upper limit does not, however, limit the high
end of pressures displayed. All pressures above the maximum value will be displayed as red.
01/04/07
Presto-Scan User Manual (RevH)
29
Note: Saturated sensels are always displayed as red, regardless of the Legend’s upper limit setting.
Unsaturated sensels may also be displayed as red based on this setting.
Sample Pressures
Three sample Balance pressures are included with Presto-Scan to serve as a quick comparison to client Balance
pressure movies, including Normal Foot, Flat Foot and High Arch. These sample mats are only visible when a Balance
window is open. When in Documentation Mode, new balance snapshots may be recorded and saved.
By selecting Options -> User Preferences, the user may customize which sample pressures are displayed.
Normal Feet:
Flat Feet:
High Arch Feet:

The Main Menu
The Main Menu section is a comprehensive look at each option in the Menu Bar. The most frequently used items in the
Main Menu also have an icon on the Toolbar. Familiarity with MS Windows is assumed, so menu items that have the
same function in standard Windows applications are not described in this manual.
Note: Not all menu items are available all of the time. When an option is unavailable, it will appear grayed
out.

The View menu items and corresponding Toolbar
icons control the primary display functions for the
active Walk or Balance windows. When one of the
options is enabled, it will have a check beside it in
the pull-down menu, and its Toolbar icon will be
depressed.
Note that the sensor data does not change when changing modes;
only the appearance of the display is affected.
2-D Contours displays the recording as a two-dimensional, contoured
image (shown at left). The sharp corners of the sensor output are
smoothed, making the pressure boundaries easier to discern. 2-D
Contours is the default view.
01/04/07
Presto-Scan User Manual (RevH)
32
3-D Contours displays the recording as a three-dimensional image, in which
higher pressures are shown as solid peaks (see image at right). The 3-D
Contours display is especially useful in comparing pressure areas that are
above the maximum pressure setting on the Legend.
In the 2-D Contours display, all pressures above the maximum pressure
setting are shown as red, and cannot be distinguished from each other;
whereas in 3-D Contours modes, pressures are displayed as peaks, and
relative pressure differences are readily apparent.
When you are in 3-D Contours mode, a separate "rotate" function is available.
Click on the screen with the mouse cursor to rotate the display 5 degrees
counter-clockwise. Hold down the Shift key while clicking to get top-forward
vertical rotation. Hold down the Ctrl key with either of the previous functions
to get the reverse effect.
Peak displays the maximum pressure value that each sensel reached during
the footstep, in one composite frame. This option allows you to view, at the
same time, the highest pressure experienced by each part of the foot during a foot strike.
Percentage displays the percentage of total force exerted by the client’s feet when the software is in Balance view. The
numbers in rectangular boxes at the bottom center of the sensor show the division of the total force (100%) between
the right and left feet. The smaller numbers in the pentagonal boxes at the top and bottom of both the right and left side
represent the division of force between the front and back of the foot. For example, if the pressure on the left foot is
53%, the number 53 will appear in the large block at the left of the center line on the sensor. However, the smaller
numbers in the boxes to the top left and bottom left might read 45% and 55%, respectively. This would indicate that
45% of the total force on the left foot is placed on the front of the foot, while 55% of the total force on the left foot is
placed on the heel of the foot.
With "Show Percentage" turned on:
With "Show Percentage" turned off:
Line displays measurement lines within either the balance window or Walk Window. These lines can be used to
measure distance from one point to another, and are movable. When the Line feature is toggled on, two red lines appear
in the Balance window (or one line will appear in a Walk window).
These lines measure distance in inches or centimeters (this measurement can be changed under Options -> User
Preferences). Dragging either endpoint of the line will allow you to move the lines to a new location. The distance
automatically updates in real-time.

not all the Movie functions will be
available in all modes.
The following diagram and explanation refer to all the movie functions found on the Toolbar when in Documentation
Mode.
Play Forward plays the recording forward, starting at the current
frame. The movie will play in the desired direction indefinitely,
looping back to the first or last frame each time.
Play Backward plays the recording in reverse, starting at the
current frame. The movie will play in the desired direction
indefinitely, looping back to the first or last frame each time.
Stop stops either playback or recording. If a recording is in
progress, Stop will cause the software to stop recording the active movie, even if the selected number of movie frames
has not yet been recorded. You can also stop recording by pressing the F4 key. The Ctrl key does not affect the Stop
option.
Next Frame plays the recording forward one frame each time it is clicked.
Previous Frame plays the recording in reverse one frame each time it is clicked.
Last Frame positions the recording at the end (final frame).
First Frame positions the recording at the beginning (frame 1).
Record is used to make a recording (movie). You can also begin recording by pressing the F2 key. When you are in
Walk Mode, the recording option is disabled, because the recording is already in effect. By entering Walk Mode, the
software will record data as soon as there is pressure applied to the sensor. This is referred to as "triggering". If
"triggering" is in effect, recording will not begin until the start trigger event occurs. When data is being recorded,‘(Rec)’
is added to the window's Title Bar, and the window’s Status Bar displays each frame number as it is recorded. Movies
created by the Presto-Scan system are stored as *.fsx files.

Snapshot is used to make a single-frame recording (movie). When Snapshot is selected, the software records a single
frame of sensor data as it appears in the current window. You can also take a snapshot by pressing the F3 key. When
data is being recorded,‘(Rec)’ is added to the window's Title Bar. Movies created by the Presto-Scan system are stored
as *.fsx files.
Play Speed sets the speed in which the movie plays. Choices are Slowest, Medium Slow, Normal, Medium Fast, and
Fastest. It is usually beneficial to play the movie at a Medium Slow speed in order to analyze the movement in proper
detail. Otherwise, the movie may be too fast to notice the change in pressures.

DISPLAY AND DOCUMENTATION MODES
The Presto-Scan software can be used in one of two modes: Display or Documentation. The first time that the Tekscan
software is opened after installation, the
User Preferences dialog box will
automatically be displayed. Choose which
mode the software should run by clicking
either Display mode or Documentation
mode. You can switch between modes by
going under Options -> Set User
Preferences at any time.
DISPLAY MODE
Display Mode is designed for general use in which it may not be necessary to save plantar pressure movies for each
individual client. It allows a user to record plantar pressure movies for a client as the client either walks across the
sensor or simply stands on it. Display Mode allows client data to be recorded and displayed. Movies can be manipulated
for general analysis and printed in either black and white or color. However, movies recorded in Display Mode cannot
be saved for access at a later time.
Display Mode has a different set of Toolbar buttons than Documentation Mode. The buttons in Display Mode are limited
to only essential buttons required for basic
recording and playback.
The Toolbar buttons in Display Mode are
shown below:
DOCUMENTATION MODE
Documentation Mode is designed for advanced usage in situations where it is desirable to save client plantar pressure
movies and recordings for later review and analysis. It allows a user to record plantar pressure movies for a client as
the client either walks across the sensor or simply stands on it. Documentation Mode allows client data to be entered
and saved. Plantar pressure movies can be manipulated for general analysis and printed in either black and white or
color. Movies recorded in Display Mode may be saved for access at a later time. Saved movies may also be loaded as
comparative examples for display to the right in a Balance window.
Because of the more advanced functions available with Documentation mode, there are additional Toolbar buttons
displayed in the software. These include buttons for saving recordings and for more advanced playback. These playback
buttons are described in more detail in the Movie Menu and Reviewing a Recording section.

TAKING A RECORDING
Presto-Scan allows you to capture your client’s walking or standing plantar pressures over a period of time through a
process called "recording". A Presto-Scan recording is similar to a video recording, since you can rewind your
recording, play it and replay it as many times as you wish. These pressure data recordings are also referred to as
"movies".
In either Display or Documentation Mode, the user has access to two types of recordings: Balance and Walking.
Depending on what type of information is needed about a client’s plantar pressure, one or both types of recordings can
be made.
BALANCE
To enter the Balance window (shown below), click the button on the Toolbar that shows two feet pointing in the same
direction. If client data has been entered into the Client File Management System, a new Balance window will open for
the same client. The Balance window is ideal for comparing percentages of force placed on each section of each foot
when the client is standing normally. A snapshot of the
pressures may be recorded, or several frames can be
recorded as the client rocks back and forth on his or her
feet.
In Balance Mode, you must manually press the Record or
Snapshot button to record pressure. The sensitivity button
is always enabled for Balance Mode, and can be adjusted as
necessary. This works differently than Walk Mode, where
the recording is set automatically, and waits for a pressure
to "trigger" the recording.
Balance recordings display a single red and white marker
that represents the Center of Force between the left and
right feet. This red COF marker is displayed in the image
below. In Options -> User Preferences, this can be
changed to include two green and white markers that
represent the Center of Force over each foot. Dynamic
recordings display the COF with a trajectory line that follows
the path that the COF traveled during the recording.
When in Balance Mode, while the movie is being recorded or after a recording, the percentages are displayed on both
the left and right side of the window, and across the bottom. For example, in our recorded movie above, the following
percentages are shown:
Weight on Left Forefoot: 58%
Weight on Left Heel: 42%
Weight on Right Forefoot: 51%
Weight on Right Heel: 49%
Weight on Left Foot: 54%
Weight on Right Foot: 46%
01/04/07
Presto-Scan User Manual (RevH)
40
The user also has the ability to write customizable wording that pertains to the subject's foot pressure within the movie
after it has been recorded, or after a snapshot (as shown below):
While there is a drop-down list of available choices, the user can override these selections and freely type in their own
wording. All Percentage information and wording that is entered here will be printed out when File -> Print is selected.
Refer to the Printing section for more information.
Note: When your computer screen display is set to "Screen Saver" mode, stepping on the sensor, pressing a
key on the keyboard, or moving the mouse will automatically bring the Presto-Scan display back to
"Balance Mode". This will greatly reduce the amount of operations that need to be performed in order to
take a recording.
WALK
To enter the Walk window (shown below), click the button on the Toolbar that shows two feet pointing in opposite
directions. If client data has been entered into the Client File Management System, a new Walk window will open for the
same client. The Walk window allows the user to record a foot strike from each of the client’s feet. These foot strikes
can be played back at various speeds and analyzed. As a recording is being taken, the software prompts the user with an
arrow to indicate which direction the client should walk. It is best to have the client focus on a spot straight ahead at eye
level. Ideally, as space permits, the client should step across the mat on their second, third (or more) step.
In Walk Mode the program immediately and automatically starts to record, waiting for the trigger (waiting for the load)
on the sensor. The sensitivity button will not be enabled in Walk Mode. If you would like to adjust the sensitivity in Walk
Mode, first press the Stop button to stop the recording. Then adjust the sensitivity as desired. Next, press the Record
button. The program will wait for the load (trigger) to be applied to the sensor once again.
For Walk recordings, the Center of Force is displayed as a red and white marker for each footstep. Dynamic recordings
display a red trajectory line that follows the path that the COF traveled during the footstep.

When the recording is completed in Walk Mode, the view is automatically set to show the "Peak" pressure in a singleframe. While Peak is enabled, the user should be able to clearly identify right away where the peak pressure is located
under each foot. This is displayed on-screen by a small black square surrounding the peak pressure. This is the Peak
pressure for the entire movie. When Peak is disabled (by clicking the Peak button in the Toolbar), the Walk recording
automatically plays forward in a loop. Press the Stop button to halt the playback.
The user also has the ability to write customizable wording that pertains to the subject's foot pressure within the movie
after it has been recorded (as shown below):
While there is a drop-down list of available choices, the user can override these selections and freely type in their own
wording. All Percentage information and wording that is entered here will be printed out when File -> Print is selected.
Refer to the Printing section for more information.
Note: When your computer screen display is set to "Screen Saver" mode, Stepping on the mat
(placing a load on the mat), pressing a key on the keyboard, or moving the mouse will
automatically bring the Presto-Scan display back to "Balance Mode". This will greatly reduce the
amount of operations that need to be performed by the user in order to take a recording.
TAKING A WALK RECORDING
1. Open a new Walk window for the client by clicking File -> Walk Mode or by clicking the Walk Mode button
on the Toolbar.
2. The software will prompt the client to walk across the mat in the direction of the arrow. When in Walk Mode,
the software has already begun to record the movie. However, nothing is recorded until the subject places a
pressure or load on the sensor. Have the subject take a few steps back from the sensor, and then walk across it
with their left foot.

•
Focus on something directly in front of them and on the wall, and walk towards it.
Walk with a normal gait.
Take at least one step (or more) before stepping on the mat.
4. When both left and right foot strikes have been recorded, recording will automatically stop and the plantar
pressures will be displayed in Peak mode. You may now review and analyze the recorded plantar pressure data
(refer to the Reviewing a Recording and Analyzing Plantar Pressure Data sections). If the first recording is not
successful for some reason, you can easily create another recording.
The newly recorded movie will automatically be named, using the active client’s name and a two-digit number.

Only one photo can be linked to the
movie. Removing a linked photo causes
the warning message shown at right to
appear on-screen.
Toolbar and Status Bar Options
When a photo is linked to the movie, the following toolbar and status bar options are available from the top and bottom
of the photo window, respectively:
•
•
•
•
•
Select Photo: This option lists
all photos that are linked to the
current movie. Clicking on the
drop-down arrow allows you to
select from any of these linked
photos. When a photo is
selected, the movie
automatically jumps to the
corresponding linked frame.
Add Photo: Allows you to add a
photo and link it to a movie
frame.
Remove Current Photo: Allows
you to remove the currently
displayed photo, thereby
removing its link to the movie’s
frame.
Copy Photo: This command
copies the photo to the windows
clipboard. You can then paste
the photo to any other
application that supports photo
files, such as Microsoft Word or
Excel.
Select Size (Zoom): Allows you to quickly select from a number of preset zoom factors. Options are 25%,
33%, 50%, 75%, 100% and Fit to Window. These scale factors are relative to the original photo size. You can
also drag from the bottom-right edge of the window to expand or contract the photo and photo window, while
maintaining the photo’s aspect ratio. Note: the photo’s current scale is also displayed as a percentage within
the middle of the status bar.
Movie Playback
During movie playback, when one photo is linked to a movie, the photo is continually displayed for the entire duration
of the movie.
If more than one photo is linked to the movie, when the movie is played, the photo switches to the next photo at the
movie frame for which the photo is linked. For example, if you associate image1 to frame 1 and image2 to frame 10,
when the movie plays from the beginning, image1 is displayed until the movie reaches frame 10. When the movie
reaches frame 10, image2 is displayed until it reaches another frame for which a photo is associated, or until the end of
the movie if no other photos are linked to the movie.

Smart Docking
By default, the photo is docked to the right side of the movie window
(called “Smart Docking”). When you drag the movie around the
screen (by clicking on the title bar of the movie and dragging with
your mouse), the photo window moves with the movie. This helps you
identify photo windows in situations where you have several movie
and photo windows open on-screen at once.
Conversely, you can move the photo window independently of the
movie window by clicking and dragging on the photo window’s title
bar. The reason for this is so that you can dock the photo window to a
different side of the movie window. If, for example, you want the
photo to dock to the left side of the movie window instead of the right,
you can click and drag the photo window’s title bar and move the
photo window to the right side of the movie window. When you then
move the movie window around the screen, the photo window
automatically docks to the left side of the movie window.
If you prefer to unhinge the photo window entirely so that the movie window moves independently from the photo
window, right click and select Disable smart docking from the context menu (see image above right). You can now
move both windows independently of one another.
Copying Linked Photos
Using the Copy Photo command located as an icon on the toolbar, you
can copy any photo to the windows clipboard. The copy can then be
pasted to any other application that supports photo files, such as
Microsoft Word, PowerPoint or Excel.
When you copy and paste the photo in this manner, the photo is
always displayed at its original photo size. If you want to keep the
photo’s size the same as what you see on-screen, right-click over the
photo window. From the context menu, select Copy Photo (Current
View Size). When the photo is pasted into other programs, the size
will remain consistent with the photo’s current view displayed within
the Tekscan software.
Missing Photo Links
When a photo is linked to a movie, there is a connection that is made between the
photo file location and the movie. If the photo is moved, this connection is
broken. When this happens, your photo is no longer displayed when the movie is
opened (see image at right).
To correct this situation, first remove the file using the Remove Current Photo
icon on the toolbar, and then link the photo once again by clicking the Add Photo
icon on the toolbar. When the “Open” dialog is displayed, select the new location
for the photo; where the photo was moved. The photo is visible once again.

ANALYZING PLANTAR PRESSURE DATA
As you review Balance or Walk pressure data, you will want to make use of the analysis tools that Presto-Scan
provides. This section discusses these Analysis tools.
DISPLAY OPTIONS
The following Presto-Scan display options are essential in analyzing plantar pressure data: 2-D Contours and 3-D
Contours Views.
2-D Contours displays the recording as a two-dimensional, contoured image. The sharp corners of the sensor output
are smoothed, making the pressure boundaries easier to discern. 2-D Contours is the default view.
3-D Contours displays the recording as a three-dimensional image, in which higher pressures are shown as solid
peaks. This display can often provide a view of pressure data that is easier to comprehend than the 2-D Contours
image.
The 3-D display is especially useful in comparing pressure areas that are above the maximum pressure setting on the
Legend. In the 2-D display, all pressures above the maximum pressure setting are shown as red, and cannot be
distinguished from each other; whereas in 3-D Contours mode, pressures are displayed as peaks, and relative pressure
differences are readily apparent.
As you can see in the two figures of a foot (below), the 2-D Contours display shows where there is a suspected area of
risk (areas of high pressure), but the 3-D Solid display gives a much clearer view of exactly how high the pressures are
at those points.
2-D Contours View
3-D Contours View
Peak displays the maximum pressure value that each sensel reached during the footstep, in one composite frame. This
option allows you to view, at the same time, the highest pressure experienced by each part of the foot during a foot
strike. By default, the movie will automatically enable "Peak Mode" as soon as a Walk Mode recording ends. Clicking
the Peak icon on the Toolbar (turning peak mode "off") sets the movie in motion. The movie plays forward in a loop
until the Stop button is pressed.

Percentage displays the percentage of total force exerted by the client’s feet when the software is in Balance Mode. The
numbers in rectangular boxes at the bottom center of the sensor show the division of the total force (100%) between
the right and left feet. The smaller numbers in the pentagonal boxes at the top and bottom of both the right and left side
represent the division of force between the front and back of the foot. For example, if the pressure on the left foot is
53%, the number 53 will appear in the large block at the left of the center line on the sensor. However, the smaller
numbers in the boxes to the top left and bottom left might read 45% and 55%, respectively. This would indicate that
45% of the total force on the left foot is placed on the front of the foot, while 55% of the total force on the left foot is
placed on the heel of the foot.
With "Show Percentage" turned on:
With "Show Percentage" turned off:
Line displays measurement lines within
either the Balance or Walk window.
These lines can be used to measure
distance from one point to another, and
are movable. When the Line feature is
toggled on, two red lines appear in the
Balance window (or one line will appear
in a Walk window).
These lines measure distance in inches or centimeters (this
measurement can be changed under Options -> User Preferences.
Dragging either endpoint of the line will allow you to move the lines to
a new location. The distance automatically updates in real-time.

White. When this item is in effect, it will have a checkmark beside it in the pull-down menu.
Background White Turned On (Default):
Background White Turned Off:
Rotate turns the entire view counter-clockwise for analysis when in 3-D Contours mode. Using the drop down menu,
Rotate moves the entire view in ninety-degree increments from its current orientation. Clicking in the window with the
mouse cursor rotates the view in five-degree increments. Hold down the Shift key while clicking to get top forward
vertical rotation. Hold down the Ctrl key with either of the previous functions to get the reverse effect.

PRINTING/REPORTING
The Print function allows you to print the contents of the Walk or Balance window, including client information,
comments and graphs, to any of the hundreds of printers that MS Windows supports. The window will be printed exactly
as it appears on the screen, and will include the options selected in Print Setup.
To print:
1. Select Print Setup from the File pulldown menu to open the "Print Setup"
dialog box (below). Print Setup enables
you to select your print options: the
specific printer, the page orientation, the
paper size and source, the margins,
content, and scaling percentage. Most of
these options are standard MS Windows
functions.
2. Select (click on) one of the following
options, under "Content" at the bottom of
the dialog box, to control exactly what
will be printed (a check mark will
appear to the left of a selected choice,
and unavailable options will be "grayed
out"):
•
Fields: Prints any fields that were entered under Comments in the File pull-down menu, as well as the
standard client fields (client’s first and last name).
Comments: Prints the comments that were entered under Comments in the Client record.
View: Prints the contents of the selected Walk or Balance window. If this option is not selected, no
sensor pressure data will be printed.
•
•
3. Select (click on) one of the following options, under "Scaling the View", to specify the size of your printout:
•
•
Fit on Page: The size of the image will be set to the largest printable area. Note that the software will
automatically rotate an image so it will print as large as possible.
Scale: When Scale is selected, you may enter a custom scaling percentage. This value corresponds to
the actual size of the sensor; so entering 100% will give you a one-to-one printout.
4. When you are satisfied with the Print Setup, click OK. Select Print Preview from the File pull-down menu, or
click the Print Preview icon in the Toolbar, to see how your printout will look. Make any necessary
adjustments to the Print Setup.
5. Select Print from the File menu, and click OK. If you receive an error message while printing, or printing does
not begin in a timely manner, close any Real-time windows and/or stop recording data. If printing does not
resume immediately, re-send the print job.

The following is an example of a printed report from a "Walk" movie:
PRINTING GRAYSCALE
The Presto-Scan software will also allow you to print the color screen display as a grayscale image. When a grayscale
(non-color) printer is installed, and is selected as the default printer (in the Print Setup or Print options in the File
menu), the image will be printed in grayscale.
In color printouts, the Pressure Legend goes from blue (lowest pressures) to red (highest pressures). The PrestoScan software does not simply print these colors in black and white, because red and blue will both print out dark and
appear to be at the same pressure. When printing grayscale, the software automatically adjusts the Legend to divide the
13 possible pressure ranges into 13 shades of gray, going from light (low pressures) to dark (high pressures). The
corresponding pressure areas on the printout of the display window will be adjusted to agree with the Legend. In this
way, the pressure differences are much more easily discerned.
Note: This option is intended for grayscale printers, and may not work correctly if printing to a
color printer, with the "print grayscale" option selected.

Percentage: Displays the percentage of total force exerted by the client’s feet when the software is in Balance view. The
numbers in rectangular boxes at the bottom center of the sensor show the division of the total force (100%)
between the right and left feet. The smaller numbers in the pentagonal boxes at the top and bottom of both the
right and left side represent the division of force between the front and back of the foot. For example, if the
pressure on the left foot is 53%, the number 53 will appear in the large block at the left of the center line on
the sensor. However, the smaller numbers in the boxes to the top left and bottom left might read 45% and 55%,
respectively. This would indicate that 45% of the total force on the left foot is placed on the front of the foot,
while 55% of the total force on the left foot is placed on the heel of the foot.
Play: Plays the recording in a loop.
Pressure Legend: The Pressure Legend shows the pressure range that corresponds to each of the 13 possible colors in
any open Balance or Walk window. Lower pressures are indicated by cooler colors, where blue is the lowest
pressure. Higher pressures are represented by hot colors, with red representing the highest pressures. Clicking
the triangle on the right side of the color scale and dragging it upwards or downwards can change the pressure
range represented by each color in the legend. This upper limit does not, however, limit the high end of
pressures displayed. All pressures above the maximum value will be displayed as red.

Sensor: The Presto-Scan sensor is made up of over 2,000 individual pressure-sensing locations, which are referred to
as ‘sensing elements’ or ‘sensels’. The sensels are arranged in rows and columns on the sensor. Each sensel
can be seen as an individual square on the computer screen by selecting the 2-D display mode. The output of
each sensel is divided into 256 increments, and displayed as a value (raw sum) in the range of 0 to 255 by the
software. The map number (3150) identifies the sensor type. The software uses a map to convert the pressure
detected by the hardware into the pressure data displayed in the Real-time window.
Sensor Handle: The sensor tab is placed into the sensor handle, which is connected to the Parallel interface module.
The sensor handle gathers data from the sensor and processes it so that it can be easily sent to the computer.
The latch on the top of the handle must be in the UP position to insert the sensor tab.
Show Foot COF: A setting under "User Preferences" which is not on by default. To show a Center of Force for each foot,
click to place a check in this box. A green and white icon will indicate the COF for each foot.
Show Legend with New Recording: A setting under "User Preferences" which automatically opens the pressure legend
when a new recording window is opened.
