Percent Time In Zone/Quadrant: These values represent the percentage of test time the patient
spends in each Zone/Quadrant during the test.
The Target Zones, A, B, C, and D, are equal to specific ranges of deflection and radiate in con-
centric circles from the center of the foot platform as follows:
• Zone A = zero to five degrees foot platform deflection from level
• Zone B = six to ten degrees foot platform deflection from level
• Zone C = 11 - 15 degrees foot platform deflection from level
• Zone D = 16 - 20 degrees foot platform deflection from level
Quadrants represent the four quarters of the Test Grid in the X and Y axis as follows:
For the "Both Feet" protocol:
• Quadrant 1 = right anterior
• Quadrant 2 = left anterior
Quadrants represent the four quarters of the Test Grid in the X and Y axis as follows:
For the "Both Feet" protocol:
• Quadrant 3 = left posterior
• Quadrant 4 = right posterior
For the "Single Foot" protocol:
• Quadrant 1 = lateral anterior
• Quadrant 2 = medial anterior
• Quadrant 3 = medial posterior
• Quadrant 4 = lateral posterior
Test Grid: Provides a visual representation of Time Spent in Zone/Quadrant. View is orientated
as if patient were looking down at foot platform while facing the display module.
Anterior/Posterior and Medial/Lateral Deflection Graphs: Provides a visual representation of A/P
and M/L deflection during the test. View is oriented as if foot platform were positioned at eye
level on a horizontal plane. X axis = time and stability level.
