Utilizing directional preference in the management of cervicogenic headache: a case series.

background/purposeHeadaches are among the most common complaints requiring medical care, and annual expenditures for this condition are estimated to be 14 billion US dollars. The International Headache Society (IHS) describes cervicogenic headache (CGH) as a secondary type of headache emanating from the cervical spine which may be referred to one or more regions of the head and/or face. Mechanical Diagnosis and Therapy (MDT) is an approach shown to be effective in the management of spinal musculoskeletal disorders; however, there is limited evidence as to its efficacy in the management of CGH. The purpose of this case series was to examine the MDT approach in the assessment, classification, and management of a sample of patients experiencing cervicogenic headache. CASE DESCRIPTION: This study was a prospective case series. Following IRB approval, 15 patients meeting the study inclusion criteria were recruited from a hospital-based outpatient physical therapy clinic. All subjects received a physical therapy examination by a Diploma trained MDT clinician which included but was not limited to patient self-report forms and the testing of repeated end range movements. The Numerical Pain Rating Scale (NPRS), Neck Disability Index (NDI), Headache Disability Index (HDI), Yellow Flag Risk Form (YFRF), Cervical Flexion Rotation Test (CFRT), and the Craniocervical Flexion Test (CCFT) were administered at the initial visit, 5th visit, and 10th visit or discharge, whichever occurred first. The NPRS, NDI, and HDI were re-administered at a 3 month follow up. Following the initial examination, patients were classified into the MDT categories of derangement, dysfunction, postural, or 'other' and then received intervention based on directional preference. OUTCOMES: Fifteen subjects (mean age, 45.9 years; F = 11, DISCUSSION/

conclusionThe diagnosis of CGH is difficult to determine based on pathoanatomical assessment. This case series suggests that the patient's response to repeated end range movements may indicate a directional preference for manual procedures and exercises which may be used in management of musculoskeletal conditions such as CGH.
