NEFERT

NEFERT (Neck Flexion Rotation Test) is a medical examination procedure developed in 1999 by German neurootologist Claus-Frenz Claussen.

The procedure serves for investigating intracorporal movement differences between head and body, especially at the atlanto-axial joint and the lower cervical spine column. The method can help diagnosing sprains of the neck, stiff necks, and whiplash. According to the National Center for Biotechnology Information within the National Institutes of Health, the procedure is "commonly used in clinical practice to evaluate patients with cervicogenic headache."

The test consists of six movements, which can also be distinguished into four phases. The movements are performed by the patient in a standing position.

If the test results are interfered by unconscious shoulder movements of the patient, a second test course is performed, during which the examining person holds the patient's shoulders with the hands. The test results are recorded and graphically evaluated by a computer, for example with the help of Cranio-corpography.
