Symmetry
The Symmetry program may aid in achieving a more balanced exercise stroke for patients with
bi-lateral deficiencies, such as stroke patients and post-op knee patients. The program will
measure the left and right power through the pedal range. The Dot Matrix display will show a
graph indicating the leg power symmetry so the user has a visual feedback to aid in improving
the involved limb’s strength. The program will also work for upper body only. When pushing the
handles, the graph will be reversed (Left side will actually be displaying right arm information). It
will be correct if the patient is pulling.
1. Press the Symmetry key then press the Enter key.
2. The message window will prompt you to enter the Age, Weight and Time for the program.
You may enter the Age using the Up and Down keys or the numeric key pad then press
the Enter key to accept and proceed to the next screen.
3. Now you are finished editing the settings and can begin by pressing the Start key. You
can also go back and modify your settings by pressing the Enter key. NOTE: At any time
during the editing of Data you can press the Stop key to go back one level, or screen.
4. During the program you will be able to scroll through the data in the message window by
pressing the Enter key.
5. When the program ends you may press Start to begin the same program again or Stop to
exit the program, or you can save the program you just completed as a User program by
pressing a User key and following the instructions in the message window.
Biofeedback Graph:
Below is a sample picture showing the symmetry graph. In the message window there is an
average watt measurement and it is indicating that the left leg is producing more power than the
right leg, 41 vs. 34 watts. The graph reflects the higher wattage of the left leg. If the power is equal
in both legs only two dots would be lit on the bottom center of the graphic screen. Press the Enter
key to view the Symmetry data.
