Brief summary
This study evaluates biofeedback delivered through a smartphone as a treatment for migraine in adolescents. Three out of four participants will receive treatment as smartphone delivered biofeedback training, and one out of four participants will receive treatment as a sham-biofeedback app.
Detailed description
Biofeedback is a behavioral treatment without known side effects. In biofeedback patients learn control over bodily reactions through feedback visualised on a screen. Typical bodily reactions that are displayed is heart rate and muscle tension. Biofeedback has for decades been considered as effective preventive treatment of migraine among children and adolescents. In spite of that, it is not available to most patients in need. This is most likely because it requires specialised stationary equipment and a trained therapist. In this project, the researchers have developed a new smartphone biofeedback app connected to wearable, wireless sensors measuring muscle tension, finger temperature and heart rate. The app and sensors will be used to deliver biofeedback treatment to adolescents suffering for migraine. The goal of the study is to investigate the effect of the biofeedback treatment and the sham-biofeedback treatment on migraine headaches.

Masking description
The randomization number will be drawn sequentially from a list of 40 numbers where one random in every four numbers results in downloading a sham-version of the app. Both versions of the app look alike and no pattern in the 5-digit number or the randomization list can reveal which version of the app is given. This will ensure blinding of both participants and study personnel. Breaking of the randomization will be made after follow-up of the last participant. The software developers will at this point reveal what 5-digit numbers corresponded to the biofeedback or sham version of the app.
Intervention model description
The study will begin with a one-month baseline period, followed by a two-month treatment period. Participants will randomly be assigned to one of two groups by a computer-generated block-randomization list. In each block of four, participants will have a 75% chance of being allocated to the biofeedback group and 25% chance of being allocated to the sham group, to ensure 30 participants in the biofeedback group and 10 in the sham group. The randomization list will remain inaccessible to the investigators until end of follow-up of the last participant. Both participants and personnel will be blinded to the intervention given. It should be noted that this study is intended as a pilot study, and not a randomized controlled trial. Still, we wish to use randomization and blinding to ensure that the group receiving sham treatment is a random subset of the study population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Headache frequency | Baseline and last 28 days of treatment | Mean change in headache frequency from baseline to end of treatment. Evaluated as number of headache days. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Responder rate | Baseline and last 28 days of treatment | Defined as positive if there has been more than 50% decrease in headache frequency from baseline to end of treatment |
| Maximal pain intensity | Baseline and last 28 days of treatment | Mean change in maximal pain intensity from baseline to end of treatment. Rated on a 4 point scale (0=no headache; 3=severe headache). |
| Abortive drug consumption | Baseline and last 28 days of treatment | Mean change in abortive drug consumption form baseline to end of treatment. Defined as days with use of abortive drugs. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Treatment adherence | During the two month treatment period | Estimate of adherence by evaluating how many treatment sessions were completed during the treatment period. |
