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.
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 re ects 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.
Note:
The Symmetry program uses a power table and velocity
measurements to generate the watt readings; they are not from direct
force measurements.
