The Efficacy of Neurofeedback Mindfulness in Migraine Management

Migraine Headaches Clinical Trial

Official title: Study Protocol for a Randomized Controlled Trial on Neurofeedback Mindfulness and Its Efficacy on Migraine Management

Status Completed

Clinical Trial Summary

This longitudinal randomized controlled trial explored how long-term practice of neurofeedback mindfulness would be helpful for migraine management when compare dot a similar controlled intervention. All the participants went through assigned 10 minutes practices on a daily basis for 8 weeks. Behavioural reports and migraine characteristics were compared before and after the intervention.

Clinical Trial Description

This study was announced on PAWS platform from September 2020 until December 2021 available for students, professors, employees and alumni at the University of Saskatchewan. Before the participant recruitment, 218 volunteers provided their consent and filled out the initial survey to be evaluated based on the study's criteria. The eligibility criteria included age, an official diagnosis of migraine from a clinician or meeting criteria for a migraine diagnosis based on ICHD-3 (2018), residing in Saskatoon area, having frequent headaches at least once a month, and access to smartphone and internet connection. A priori exclusion criteria for this study were comorbidity of Raynaud's syndrome or diabetes, frequent use of a preventative migraine treatment, and background experience with meditation. After applying inclusion and exclusion criteria, participants were randomly selected for the NM or the control group. An invitation letter was sent to 112 volunteers (NM=53, control=59); out of which 11 individuals (NM=4, control=7) refused to participate due to different reasons (e.g., COVID-19, difficulty with device delivery, starting preventative medication or unstable migraine attacks) or never responded to the invitation or the follow up emails. 101 participants started the RCT (NM=49, control=52) but after attritions, 68 participants completed their total practice days. 4 participants in the control group were excluded from data analysis due to missing questionnaires and therefore insufficient data for repeated measures analysis. Three participants were also excluded due to inconsistency in their data or ethical considerations. As a result, we ended up having 61 participants (meditation=34, control=27) with complete intervention and available data for analysis. The mean average age was similar between the NM (age M= 34.11, SD= 9.89) and control groups (age M= 31.51, SD= 10.20). In the NM group, there were 28 females (82.4%) and 6 males (17.6%) and in the control group, we had 21 females (77.8%) and 6 males (22.2%). At the end of the study, the NM group had filled out 148 diaries, and the control group provided 100 diaries about their headaches. Data collection occurred between September 2021 to December 2022 dependent on the joining date of each participant. The initial questionnaire of this study included 45 open-ended and multiple-choice questions (26 min to complete) and was used to distinguish the inclusion and exclusion criteria. Having given the consent, the volunteers provided demographic information about their headache characteristics, family history of migraine headaches, and background experience with meditation. After checking the availability criteria, the invited participants received a coded email information with a description of their practice, as well a copy of their consent form and contact information of a researcher in charge for device delivery. Before device delivery, the researchers checked COVID-19 self-screening measures. A zoom meeting was scheduled (estimated for 30-60 minutes) after the participants would receive the device. In the initial meeting, the participants were introduced to focused listening and mind wandering states; they were suggested to block mind wandering during the sessions by attending to the audiobook carefully. Followed by the practice session, the participants would receive the same feedback of brain activities as shared by the NM group. The feedback included a timeline indicating their brain states (active, or relaxed) during the practice as well as reinforced consistent relaxed states. In this way, the control group task was identical to the NM group except that they listened to an audiobook instead of doing the NM intervention. For the whole duration of data collection (September 2021-December 2022), the sessions were monitored daily via MUSE Connect and were transcribed on an Excel file with information about numbers and reasons for missing days. During the online session, participants received a brief introduction to the study goals and the participants' assigned task, and they were instructed on how to use the headband and the MUSE app to complete their given exercises both in the NM and control group. Participants were required to complete the pre-intervention questionnaire on the day of the initial meeting. After the initial meeting, they received daily reminders scheduled for 8:00 p.m. by a researcher. They were required to respond to the researcher by sending "1" for a complete session. Participants received a manual reply to keep them more engaged in the intervention. All the participants' practices were monitored daily via MUSE Connect. Information was collected about the duration of their practice, as well as the percentage of their relaxed or active states. In case of a pause in daily practices for more than three sessions, the researcher would send a follow up email asking for the reason of the pause in the intervention. In the event of having issues with the device, a EEG headband replacement was scheduled to be delivered to participants upon their availability. Additionally, the participants received weekly reminder text messages for headache diary questionnaires that were accessible via a SurveyMonkey link on their cellphones. Time to complete the diaries was estimated about 9 minutes, and the diaries included 24 multiple choices about subjects' recent headache experience. On Week 8 of the study, the participants were given the post-intervention questionnaires to complete. In case of not completing the questionnaires, reminder emails were sent for 1 week. Since this study was demanding and expected high amount of commitment for a long period of time, the participants' collaboration was appreciated by allowing them to keep their MUSE EEG headband at the end of the study after completion of the data. The participants who withdrew before completion were also allowed to keep their device. Based on the rate of withdrawals and commitment to fill out the questionnaires, the attrition rate was 35.84% in the NM group and 54.23% in the control group; this made the total rate of attrition up to 39.60%. Since the rate of adherence to completing questionnaires and staying on task was different in the two groups, regardless of equal and balanced task requirements, this information is used as an indication of the interventions' feasibility and participants' adherence to the tasks. We utilized five measurements, administered to participants before and after the study. On average, completing the five questionnaires was estimated to take about 13 minutes. These measurements collected information about migraine disability (MIDAS), headache severity (HIT-6), headache management self-efficacy (HMSE), anxiety (BAI), and depression (CES-D). ;
