Special Tests

This section gives an overview of the special tests that may be performed if the examiner believes they are relevant for the examination process. Sensitivity (which is the ability of a test to correctly determine whether an individual has an impairment or disease) and specificity (which reflects the tests ability to correctly identify an individual as disease-free) are crucial parameters that reflect the quality of a test.

The special tests incorporated and demonstrated in this section have been chosen based on their sensitivity and specificity values as well as their practicability. To understand why exactly these tests have been chosen, the practitioner is advised to take a closer look at the THESIS which defends this section from an evidence based point of view. It explains more about the choices that have been made which led to the inclusion of these tests. It is important to realize that handling and as well as interpretation of outcomes may differ amongst practitioners.

It is recommended to use certain special tests in certain combination with other tests in order to increase the likelihood of ruling a diseasein or out. See THESIS, section “Recommendations” for further discussion.
