Headache Analysis and Intervention

Hasselt University36 enrolled

Overview

Diagnosing and treating posture-related headache (PRH), such as tension-type and cervicogenic headache, is seriously hampered because of common features and complex interaction of the neurological and musculoskeletal system. Current therapies are therefore not as effective and the population of patients with PRH keeps on increasing. The diagnostic as well as the therapeutic process need more structure in order to select the most effective treatment; thereby contributing to preventive measures. This goal can be achieved through fundamental research with a clinically oriented background. Our study starts from a clinical problem, with a growing incidence, and is therefore highly relevant. Because sitting-posture seems to play an important role in PRH, the first step in the diagnostic process is to analyse postural differences between a PRH- and a control-group. In addition, the role of the dura mater in the headache-process will be examined. Patients with PRH will be classified in homogeneous groups based on these results. In a second phase individual-specific treatment programs will be composed. The general treatment-approach of postural abnormalities in the past failed because of the heterogeneous patient-populations. Sub-classifying musculoskeletal problems has been proven to be successful in the past (O'Sullivan \& Dankaerts, non-specific low back pain). Our study is divided in 2 phases: * phase 1: profile analysis (no intervention, experimental headache-group vs. asymptomatic controls) * phase 2: interventional phase (clustered headache-groups, based on the results of phase 1

Individual Profile Analysis (Physical therapy Intervention)OTHER

The Individual Profile Analysis consists of the following components: * Analysis of the sitting-posture profile: o cervical spine, thoracic spine, lumbar spine and pelvis during a longitudinal provoking task (working at a laptop). * Analysis of the dural profile before and after the provoking task: o Determination of the dural sensitivity by the use of the slump-test * Analysis of the pain profile before and after the provoking task: * Determination of pressure pain sensitivity by the use of pressure algometry * Determination of the influence of pain on the quality of life by the use of the HIT-6 questionnaire

Outcomes

Primary Outcomes

Sitting-posture-profile

Sitting-posture will be measured with a 3D-video analysis (Bonita, ©Vicon Motion Systems Ltd. UK). Markers are placed on specific anatomical reference points on the participant. Afterwards angles (°) will be automatically calculated (Nexus, ©Vicon Motion Systems Ltd. UK)

Time frame: day 1

Pain-Profile

'Pain Pressure Threshold' will be measured. Through pressure- algometry (a) 'Pressure Pain Detection Threshold' (kPa/cm²) and (b) 'Pressure Pain Tolerance' (sec) will be determined (Somedic Sales AB, Stockholm Sweden).

Time frame: day 1

Sitting-posture-profile

Time frame: week 1 up to week 8

Secondary Outcomes

Headache-related medication-use, headache intensity, duration and frequency.

Through the use of a specific diary the secondary outcomes will be evaluated.

Time frame: week -4 up to week 8

Impact of headache on the quality of life.

The 'Headache Impact Test (HIT-6)' will be used.

Time frame: week -4 up to week 8
