Classification criteria for cervical radiculopathy: An international e-Delphi study.

Background: Establishing a set of uniform classification criteria (CC) for cervical radiculopathy (CR) is required to aid future recruitment of homogenous populations to clinical trials.

Objectives: To establish expert informed consensus on CC for CR.

Design: A pre-defined four round e-Delphi study in accordance with the guidance on Conducting and Reporting Delphi Studies.

Larger pain extent is associated with greater pain intensity and disability but not with general health status or psychosocial features in patients with cervical radiculopathy.

Pain as a result of cervical radiculopathy (CR) can be widespread, nondermatomal and individually specific, but the association between pain extent and other clinical features has never been explored. The objective of this study is to investigate whether pain extent relates to clinical variables including pain intensity in addition to health indicators including disability, general health, depression, somatic anxiety, coping strategies or self-efficacy.An observational cohort study was conducted.
