A Post-Injury Test is any test administered following suspected head trauma to screen for injury and/or following confirmed head trauma to monitor recovery. To administer a Post-Injury Test, the subject should have a non-expired Baseline. For more information see How to Administer a Baseline Test in KD.
Post-injury tests may be administered either within the mobile app or web app and follows the same flow of steps on both platforms. If it is being done on a computer, the device must be calibrated see Calibration for K-D Tests for more info.
In order to run a Post-Injury Test, navigate to the subject who needs to be tested and confirm their Baseline status. The Baseline status can be seen within the subject list, and when viewing the subject's profile as pictured below.
There are 3 Baseline status's that are differentiated by color and icon.
- No Baseline or expired Baseline
- Valid Baseline established
- Subject has failed a post-injury test and will remain in failed status until a new Baseline is established
Once you have verified the subject has a valid Baseline you can select on the Post-Injury Test button to begin. You will be presented with a screen that will explain how the test is to be administered, provide a link to an Test Set Score Sheet for grading, and allow you to select a Test Set before beginning. There are 3 Test Sets available. Test sets are the same King-Devick task with different number sets to minimize memorization. As the test administrator, be sure to have the corresponding Test Set Score Sheet to follow along for errors. Select Start Test when you are ready to begin.
The Demonstration Card is displayed, and no active, automatic timing is occurring. The test administrator should explain the task to the subject. When both the test administrator and subject are ready to begin, the test administrator should select the screen to control the automatic timing and advance to Test Card 1. The subject should immediately begin reading aloud the numbers and the test administrator should follow along on their Scoresheet to mark any errors. The subject should read aloud the numbers from left to right on the cards as shown on the demonstration card as quickly as they can without making errors. This should be done without using a hand or finger to follow the number pattern.
After the test has been completed, enter the number of errors committed, record the tester's initials, and record any comments regarding the test. Select Confirm to continue.
The results screen will be displayed. Follow the on-screen prompts and select Save Test. The test is now saved in the subject's K-D test history.
