Section 1: Operating Stride Smart – Session Screen
Metrics!
The session screen gives you a graphical overview of body weight, speed, and incline. It also
includes information on your average speed, calories burned, and total distance (Figure 1).
Changing Metric Views
Click the down arrow in the upper left-hand corner (Figure 1). Continue to click through the
arrow to toggle through pace, calories, heart rate, or distance. The measurement you select will
also be displayed on the upper display window (Figure 2).
Calories!
If you have Stride Smart, you may notice the calories displayed on the control panel and the
calories displayed on the touch screen are different. The calories on the control panel are
calculated by the treadmill, based solely on the treadmill speed. The calorie count on the touch
screen takes into account your body weight percentage and speed, and is a more accurate
reading of how many calories have been burned.
Reference http://42.195km.net/e/treadsim/ for more information on how Stride Smart calculates
calories burned.
Heart Rate
%
If you have Stride Smart, heart rate will be displayed by toggling through the touchscreen
(Figure 1). Units without Stride Smart will see heart rate displayed on their control panel.

Ending Stride Smart: Save Report!Mid-Session
Read through the other sections in the User Manual to learn how to use the features of Stride
Smart to record data. Once you have recorded videos and gait reports, you have the option to
export this data before your patients’ session is over. To do this, click on the “End Session”
button on the Session screen (Figure 1).
The treadmill will continue running while you are saving this data. This allows your patient to
perform a cool down, or continue their rehab session while you send or export the data. (Note:
Depending on your wifi connection, and the number of videos you are sending, it may take a
long time for your report to finish sending. We recommend sending all files ahead of time so that
the next patient does not have to wait to use Stride Smart).
Once you click “End Session” you can select which video recordings and gait reports that you
would like to save. Jump to Section 5 to continue reading about how to export the data via email
or USB.

Section 2: Operating Stride Smart – Video
Getting Started
The touchscreen and video display must be turned on before you begin your AlterG session. All
cameras should load automatically upon startup.
Focusing and Positioning Cameras
There are three cameras provided with your Stride Smart system: front, side, and rear.
The cameras will be labeled for each specific use.
Positioning
The front camera will be mounted on the inside of the bag.
The side camera is meant to be 3’ from the subject or closer.
Both the front and side use wide angle lenses. These cameras are not meant to exceed
a distance 3’. If you position the cameras closer to the subject than 3’ you will not need
to make any adjustments.
The rear camera is focused at 7’ from the subject. If the rear camera is positioned any
closer than 7’ you will not need to make any adjustments. If you find the need to move
any of the cameras back further, you may need to readjust.
Focusing
All cameras are focused at the factory before shipment. The side and rear cameras
have been focused to be placed right next to the window of the bag. Positioning your
cameras this way may help minimize glare from external ambient lighting.
If you desire to refocus any of the cameras, or if the cameras become unfocused follow
these steps:%
1. Set the cameras to the desired distance.
2. Loosen the Lens set screw using a small
screwdriver (Figure 3).
3. Place a subject inside the bag and refocus the lens
until it is displayed clearly on the monitor.
a. Turn the lens clockwise or counter clockwise to
establish your desired focus.
4. When satisfied with focus, lightly tight the Lens set
screw with the small screwdriver.
Camera views
Stride Smart for the M/F320 uses three cameras. The cameras are meant to be
positioned in the front, side and rear. The video feed will be displayed on the TV monitor
mounted to the front of the treadmill.
The front camera is permanently affixed inside the treadmill bag. The side and rear
cameras are attached to adjustable tri-pods and can be moved around as desired.

Gait Recording
Users can record as many gait
reports as they would like.
There is no time limit to the
length of the recording. To
record a gait report, navigate
to the gait page and click the
green “Record Gait” button
(Figure 9).
A red bar will appear at the top
of the screen signaling that
gait is currently being

Cross over gait: If you have a patient with scissoring gait
(foot crosses the midline when planted), push the “Cross
over gait” button. The button will be highlighted orange
when in effect. This allows the software to identify the
right foot when the left load cells detect weight, and left
foot when the right load cells detect weight (Figure 11).
Running mode: Switch to running mode if your patient is
jogging or running. The button will be highlighted orange
when in effect (Figure 11). The software will switch to an
alternative algorithm to track gait metrics at faster speeds.
If running mode is not detected, but needed, a yellow bar
will appear at the top of the screen with a message that
says “Gait data may not be accurate.”%

Gait Reports
To view previous Gait Reports, navigate to the Gait screen (Figure 9) and click the
“View Results” button. This is to the right of the green “Record Gait Data” button.
Select which gait report you would like to review from the
thumbnails (Figure 12).
A summary of that data session will display on the screen.
This is an average of each of the gait measurements over
the duration of your recording. (i.e. – If you recorded for
30 seconds, this is a summary of your gait symmetry over
those 30 seconds).
The thumbnails are labeled with the starting body weight
% and session time of your recording to allow you to
easily locate the report you would like to view.
Note: You will be able to email or save gait reports at the
end of your session (discussed in section 5).

Section 4: Operating Stride Smart – Pain
Pain Recording
While in a session, to record pain, click on the “Pain” button
(Figure 4).
Pain can be recorded on a scale of 0-10 (0 = no pain, 10 =
maximum pain). To record pain, select a number from 0-10
and click “Set Pain Level.”
There are no prompts during the session to remind you to
input pain. It is up to the therapist to ask the patient what
their pain level is and input it throughout the session.
Once you have set the pain level, you will automatically be
sent to the “View Results” page.
%
%
Pain Results
To review previous pain recordings, click on the blue “View
Results” button. This is to the right of the green “Set Pain
Level” button.%%
A graph displaying all recorded pain results will be plotted
here (Figure 14). The graph displays pain in relation to
approximate body weight %. (i.e. – If you recorded a pain
level of 8 at 93% body weight, you will see the number 8
listed in-between 90-100%).
Tolerance will also be displayed. This is a measurement of
the body weight % where the patient felt the least amount of
pain. (i.e. – Patient example in Figure 14 rated a pain level
of 2 at 79% body weight).
Note: Pain results will automatically be included when you
email or save your end of session reports (discussed in section 5).
