Brief summary

Whiplash is an injury caused by the rapid forward and backward movement of the neck, leading to injuries in bones or soft tissues, along with various symptoms. Recent studies indicate that muscles affected by whiplash may show increased fat buildup and reduced muscle volume. However, these changes in muscle do not completely account for the pain and other symptoms reported. Besides soft tissues, whiplash can also injure bone structures, including the cervical spine. Until now, studies focused mainly on fractures of the cervical spine, often overlooking the position and alignment of the atlas and dens (C1 and C2). The aim of this study is to evaluate the position and alignment of the Atlas in chronic whiplash-associated disorder (grades 1 or 2) and compare it to patients with tension headache and healthy controls. Additionally, it will explore how these factors relate to pain intensity, neck movement limitations, daily activities, overall improvement, and quality of life.

Detailed description

Treating some neurological conditions, like chronic whiplash-associated disorder (WAD), is highly challenging for medical practitioners. Patients with chronic WAD frequently visit their general practitioner because it's hard to pinpoint the cause of their symptoms. This makes finding the right treatment very difficult. The number of chronic WAD cases is rising worldwide, costing Europe an estimated 10 billion euros annually. Half of all whiplash injuries develop into chronic conditions, leading to significant disability and societal costs. These patients face major limitations in daily activities, greatly affecting their quality of life. Whiplash is an injury caused by the rapid forward and backward movement of the neck, leading to injuries in bones or soft tissues, along with various symptoms. Recent studies indicate that muscles affected by whiplash may show increased fat buildup and reduced muscle volume. However, these changes in muscle do not completely account for the pain and other symptoms reported. Besides soft tissues, whiplash can also injure bone structures, including the cervical spine. Until now, studies focused mainly on fractures of the cervical spine, often overlooking the position and alignment of the atlas and dens (C1 and C2). The aim of this study is to apply advanced imaging technologies to assess the position and alignment of the Atlas (C1) and the surrounding tissues. The study has three main goals: i. Study the feasibility and repeatability of state-of-the-art MRI measurements in 30 healthy controls across an age range of 18 to 75 years. ii. Assess the position and alignment of the Atlas and surrounding tissues using MRI in patients with WAD, compared to patients with tension headaches and healthy control participants; iii. Relate these MRI parameters to neurological examinations and questionnaires (patient- reported outcome measures) in patients with WAD and tension headaches.

Design outcomes

Primary

MeasureTime frameDescription
Repeatability measurement12 monthsMRI images will be used to measure the angles between the Atlas and adjacent vertebrae at two different time points in the same healthy participants.
Alignment of the Atlas12 monthsMRI images will be used to measure the angles between the Atlas and adjacent vertebrae in the patient groups.
Neurological examination scores18 monthsA neurological examination will be performed and scored during the participants' visit
Quality of life scores18 monthsThe scores will be obtained by using quality of life questionnaire

Secondary

MeasureTime frameDescription
Fat fraction24 monthsFat fraction (in %) will be measured from MRI and compared across the groups.
Blood flow24 monthsBlood flow (in cm/s) in the brain feeding arteries will be obtained from the quantitative MRI scans and compared across the groups.
Muscle volume24 monthsMuscle volume (in mm3) will be measured from the quantitative MRI scans and compared across the groups.
