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.
• Press the symmetry key then press the enter key.
• 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.
• 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. During the pro-
gram you will be able to scroll through the data (watts, symmetry,
METS) in the message window by pressing the enter key.
For best results
The symmetry program starts at level 1 and the resistance needs to
be increased manually by pressing the up arrow. Make sure to set the
resistance to a level where the patient is doing enough work to
generate a meaningful measurement. It is recommended to set the
resistance as high as the patient can perform without discomfort, but
low enough so they can complete full pedal strokes. Very low resistance
settings result in erratic or inconsistent measurements.
