can be set on the Test Options screen, but the default is three.) The display screen will
include the Trial Time and Platform Setting. Trial Number and score are displayed. If
desired, touch the <Magnifying Glass> icon to enlarge the grid circle.
NOTE: To stop a test in progress at any time and return to the Postural Stability Testing
screen with the platform locked, touch <Stop>.
12. When the first trial is finished, the screen will display ‘Trial 1 Complete,’ the platform will
return to the locked position, and a rest countdown will begin for the second trial. Touch
<Collect Data> to begin the second test trial and continue in the same manner to complete
subsequent trials.
13. After completing the test, a ‘Test Complete’ message is displayed. Touch <Results> to
advance to the Postural Stability Test Results screen.
14. At the Postural Stability Test Results screen, touch <Print> to automatically generate a
printed report if desired.
15. To save the test data from the Results screen, touch <Save Results> and touch <OK> in
response to the ‘Save Results for later reporting or export?’ prompt. The system will display
‘Save Results Completed’ after the results are saved. If a patient identifier was not entered
at the start of the session (i.e., a name or an ID number), it will need to be entered now in
order to save the results of the session. If the test result is not saved and <Back> or
<Home> is touched, the system will prompt the user for confirmation because of the
possible loss of data for the test just performed.
16. Touching <Codes/Comments> allows the user to add additional information pertaining to
the test. CPT, ICD, G-Codes or comments regarding the test can be added at the conclusion
of the test or at a future time.

<Home> icon in the upper left corner.
Motor Control Test
Similar to the Limits of Stability test, this test challenges patients to move and control their
center of gravity within a base of support. During each test trial, patients must shift their
weight to move the cursor from the center target to a blinking target and back as quickly and
with as little deviation as possible. The same process is repeated for each of the targets.
Targets on the screen blink in random order. Three skill levels allow the targets to be grouped
closer together or spread further apart, and the platform setting can be static or dynamic.
This test is a good indicator of dynamic control within a normalized sway envelope. Poor
control, inconsistent or increased times suggests further assessment for lower extremity
strength, proprioception, vestibular or visual deficiencies. The default setting for the Motor
Control test is the moderate still level.
