Intervention / Treatment
Detailed Description
The project includes two parts:
Part 1: With a longitudinal semicross-over, randomized control design the investigators will compare the clinical efficacy of a 6 month specific neck rehabilitation with standard primary health care on patients with unilateral headache and neck pain ( also termed cervicogenic headache) and study whether self-efficacy and fear avoidance beliefs predict 12 month self-reported neck function and headache frequency superior to the active range of neck movement The patients will either receive a specific neck rehabilitation program or 6 month standard primary health care before they cross over to neck rehabilitation. Sociodemographic and clinical characteristics will be collected before each treatment session and 6 and 12 months later.
Part 2: With a non-randomized comparative design including a subsample of the patients (n: 36) and healthy controls (n: 36) the investigators will explore whether there are structural changes in the cerebral grey and white matter, and whether cerebral connectivity within the default mode network (DMN and other major cerebral networks) are significantly different and whether the changes correlate to symptom severity and degree of disability.
Structural (cortical volume and thickness) changes will measured by volumetric magnetic resonance imaging (MRi) and diffusion tensor imaging (DTI), while cerebral connectivity by resting state fMRI (rs-fMRI). Whether the anticipated cerebral changes in volume, structure and connectivity are reversed after specific neck rehabilitation will be tested by repeated measurements. Analyses of MRI scans and clinical characteristics will be performed before each treatment session and 6 months later.
Statistics: Power calculations based on previous studies indicate that for the clinical part a number of 21 patients within each treatment group (a total of 42 patients) and for the MR analyses a subsample of 34 patients and 34 health controls will be sufficient to obtain a statistical power of 80% with a p-value of 5%. Due to a high drop out rate we have included a total of 57 patients. Changes between baseline and the 6 month follow up will be used for "between and within group" comparisons while 12 months data will be included for in "within-group" comparisons. Statistical predictor analyses will be performed by regression analyses. The statistician who are performing the primary end point analysis, are blinded to group assignment.

How four week baseline headache intensity reported by a numeric rating scale is associated with regional grey matter volumes measured by surface based volumetry in patients with unilateral headache and neck pain.
Time Frame: Baseline
|
Linear regression analysis will be performed where the surface based volumetric measure of cerebral grey matter is the dependent variable, and four week baseline headache intensity is independent variable.
Baseline headache intensity is based on daily measures during the last 4 weeks and is reported by an electronic diary and numeric rating scale where 0 is no pain and 10 is worst imaginable pain.
It is thus considered a continuous measure.
Age and gender are included as covariates.

Two independent comparison based on baseline rs-fMRI data to compare patients and controls.
In multivariate general linear models, the investigators will use DMN and other major cerebral networks, identified by independent component analysis (ICA), as dependent variables and test whether there are differences in cerebral connectivity between patients and controls.
All rs-fMRI analyses will be performed with the GIFT software http://mialab.mrn.org/software/gift/index.html.
