Symmetry bars/road feedback:
These two Biofeedback diagrams show how symmetrically active
exercising is being performed, i.e. how great the power difference
between the right and left legs for each direction of rotation (forwards and
backwards). The bar diagram shows the distribution of power output between
the two sides. The total of the two bars always adds up to 100 %.
With the road diagram, a bicycle moves to the left or right
on the road according to distribution of power output between the left and
right sides. In addition, the pedalling speed is indicated is indicated by
the speed at which the dotted line down the middle of the road moves. At
irregular intervals, obstacles appear on the road. If an obstacle is
avoided by appropriate one-sided exercising (obstacle on the left
more activity on the right) the obstacle changes to
green. |
Passive mode display:
When the patient is exercising passively, the colour screen shows a
bar representing the motor power currently required to move the legs. The
maximum height of the bar represents 100% of the motor power setting.
The START figure shows the starting level during the first minute of
exercising. The filled section of the bar and the percentage figure at the
bottom (56% in this example) show what percentage of the set motor power is
currently being used to move the legs. The higher the percentage
indicates that more tone may be present. During the workout a
percentage that is lower than the start would indicate lesser tone. |
