Reliability and validity of Craniocervical Dysfunction Index in Turkish Patients With Non-specific Neck Pain

The assessment of craniocervical dysfunction is performed objectively and comprehensively through the Craniocervical Dysfunction Index (CDI), which was developed based on the Helkimo Dysfunction Index. The CDI numerically grades the severity of the functional disorders of the cervical spine. Through this index it is possible to assess the craniocervical dysfunction, regardless of the opinion of the patients, of the severity of the symptoms, and of the need for treatment. The CDI objectively indicates the dysfunction of the cervical region by numerical average, assessing the degree of dysfunction and enabling the differential diagnosis, suggesting the priority and monitoring of the treatment these changes may be reassessed over time.
