The aim is to establish how headache and migraine can affect muscle hardness and tenderness in migraine patients
Migraine is a very common disorder, and many migraine patients have symptoms from their neck and muscles. 50% of migraine patients have a sensation of stiff neck in relation to migraine attacks. Furthermore it is well established, that migraine patients have tender muscles during migraine attack, which can be measured with pressure pain threshold.
In this study the investigators aim to establish the variation in ultrasound elastography and pressure pain threshold in migraine patients over time. And establish the significance of headache, migraine and prodromes on these measurements.
The study includes daily measurements of muscle hardness and muscle tenderness. The patients are asked to fulfill a headache diary and a short questionnaire asking about current headache, physical activity, stress and current infectious diseases. Sleep and physical activity is also measured objectively using a fitbit Charge2. Furthermore the patients are asked about symptoms which often are associated with migraine (prodromes).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Migraine patients | Migraine patients, who do not have any other diseases except from tension type headache. No intervention, but daily measurements of muscle hardness (Ultrasound Elastography) and tenderness (Pressure pain threshold) |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Ultrasound Elastography | Other | Measuring muscle hardness at the trapezius and neck bilateral |
|
| Measure | Description | Time Frame |
|---|---|---|
| Effect of migraine on muscle tenderness | Muscle tenderness will be measured every day with pressure pain threshold. Migraine and headache is noted in a headache diary. Is the next measurement of muscle tenderness after migraine attack higher than those with out temporal proximity to headache. (paired T-test) | Daily measurements for about 30-60 days in a row |
| Effect of migraine on muscle hardness | Muscle hardness will be measured every day with Ultrasound elastography. Migraine and headache is noted in a headache diary. Is the next measurement of muscle tenderness after migraine attack higher than those with out temporal proximity to headache. (paired T-test) | Daily measurements for about 30-60 days in a row |
| Regression analysis of muscle hardness | Muscle hardness as the dependent variable and the following as the independent variables: Current migraine, Days until next migraine attack, days since last migraine attack, Sleep quality, physical activity, Stiff Neck (subjective feeling). The result shows how much of the variability in muscle hardness that can be explained by the independent variables. | Daily measurements for about 30-60 days in a row |
