Reaction Time

What does it measure?

The Reaction Time test measures a patient's visual processing and neuromotor function.

Test Administration

The Reaction Time test takes approximately 1 minute to complete.

Before you begin your test, ensure your device is at maximum brightness and hold the device in landscape with both hands.

Remove Distractions

The Simple Reaction Time test is measuring how fast you react to changes, at fractions of a second. It is important you remain focused on the test to ensure accurate results.

Step 1

When you begin your test, your screen will appear white. Hold the device steady during this time.

Step 2

After a random amount of time, the screen will change from white to orange.

When the device screen turns orange, move the device in any direction as fast as you can. The device will vibrate once it has detected your movement. The device screen will then change back to white and you will be back at Step 1.

Repeats Steps 1 & 2

The test will continue to cycle you through steps 1 and 2 five times, measuring each cycle's respective reaction time. The five cycles allow an accurate measure of the patient's reaction time.

Results Interpretation

The Reaction Time score is the average of the 3 median measures or the average of the remaining scores after dropping the fastest and slowest score.

The fastest possible score is +/- 125ms.
