Effectiveness of Tai Chi and Acupuncture on Migraine Attack Prevention and Brain White Matter Changes: A Non-Inferiority RCT
- Conditions
- MigraineMigraine Disorder
- Registration Number
- NCT06967909
- Lead Sponsor
- The Hong Kong Polytechnic University
- Brief Summary
The goal of this clinical trial is to determine the effectiveness of Tai Chi training and acupuncture on the migraine attacks and structural brain changes in women with episodic migraine.
Researchers will compare Tai Chi training to acupuncture treatment in a randomized controlled trial with 132 female participants. Participants will:
* Be randomly assigned to either the Tai Chi group or the acupuncture group.
* Undergo a 24-week intervention, with structured sessions for Tai Chi or scheduled acupuncture treatments.
* Complete assessments through migraine diaries, questionnaires, physical measurements, MRI and TCD scans at various time points.
The study ensures participant safety through close monitoring, with medical support available in case of discomfort. Data confidentiality will be maintained, with encrypted storage and restricted access for research purposes.
- Detailed Description
The goal of this clinical trial is to determine whether Tai Chi training has the similar effectiveness in reducing the frequency of migraine attacks as acupuncture; and whether both Tai Chi and acupuncture can improve structural brain changes in women with episodic migraine. It also aims to examine whether the improvements in migraine features are linked to the structural brain changes and better cerebrovascular function after the intervention.
This study is a randomized controlled trial with 132 women who have episodic migraines. Participants will be randomly assigned to either the Tai Chi training group or the acupuncture treatment group, with 66 individuals in each group.
Participants will:
* receive a 24-week intervention, which the Tai Chi group attends instructor-led training sessions and self-practice sessions, and the acupuncture group receives 30 treatment sessions over the same period.
* Undergo assessments, including migraine diaries for migraine features and symptoms; migraine characteristics, lifestyle factors, body measurements (e.g., height, weight, and body composition), and advanced imaging techniques including MRI and TCD scans.
* Data will be collected at baseline, the 12th week, and the 24th week. MRI will be used to assess white matter changes, while TCD will be used to evaluate cerebrovascular function. Both procedures are safe and non-invasive, with specific pre-exam precautions.
To ensure participant safety, Tai Chi sessions will be closely monitored for any adverse effects such as dizziness or falls, while acupuncture treatments will be supervised to address any discomfort. If participants experience intolerable migraines, they will receive guided medication management.
Confidentiality will be strictly maintained, with encrypted data storage and restricted access for research auditing. Personal identifiers will not be linked to the data, and all records will be securely stored for five years before being destroyed.

- Primary Outcome Measures
Name Time Method The difference in frequency of migraine attacks Between 4 weeks before randomization and weeks 9-12 / 21-24 after randomization The frequency of migraine attacks will be measured by the number of attacks per month.
The difference in migraine days Between 4 weeks before randomization and weeks 9-12 / 21-24 after randomization The frequency of migraine days will be measured by the days with migraine attacks per month.
The difference of white matter abnormalities (WMAs) From the baseline to 24 weeks All the participants in the Tai Chi group will be measured with MRI. The appearance, number, size and location of WMAs will be recorded. Two experienced neurologists or neuroradiologists will be invited to review the MRI scans independently. Scheltens' visual rating scale will be used to measure the degree of WMAs. Briefly, WMAs will be separately graded in each of the following locations: frontal lobes, temporal lobes, parietal lobes and occipital lobes. WMAs will be graded as follows: 0 (no lesions), 1 (hyperintensity \< 3 mm and n ≤ 5), 2 (\< 3 mm and n ≥ 6), 3 (4-10 mm and n ≤ 5), 4 (4-10 mm and n ≥ 6), 5 (≥ 11 mm and n ≥ 1), and 6 (confluent). The sum of scores from each location will be considered as the final score. Only the women who are identified WMAs (Scheltens' visual rating scores \>0) will take the MRI test again at the 24th week.
- Secondary Outcome Measures
Name Time Method The duration of headache From the baseline to 12 weeks and 24 weeks The duration of headache recorded in the migraine diary to the nearest 0.1 hour.
Percent body fat From the baseline to 12 weeks and 24 weeks Percent body fat in %
The difference of pulsatility index (PI) From the baseline to 12 weeks and 24 weeks PI in neck vessels will be measured and recorded by Transcranial Doppler (TCD).
The difference of mean blood flow velocity (MBFV) From the baseline to 12 weeks and 24 weeks MBFV in neck vessels will be measured and recorded by Transcranial Doppler (TCD).
The difference of impaired cerebrovascular responsiveness (CVR) From the baseline to 12 weeks and 24 weeks CVR in neck vessels will be measured and recorded by Transcranial Doppler (TCD).
Height From the baseline to 12 weeks and 24 weeks Height in meters
Waist circumference From the baseline to 12 weeks and 24 weeks Waist circumference in centimeter
Hip circumference From the baseline to 12 weeks and 24 weeks Hip circumference in centimeter
The proportion of responders From the baseline to 12 weeks and 24 weeks Defined as the proportion of patients with at least a 50% reduction of the number of attacks per month.
The intensity of the headache From the baseline to 12 weeks and 24 weeks The intensity of the headache measured by a Visual Analogue Scale (VAS). This scale is most commonly anchored by "no pain" (score of 0) and "worst imaginable pain" (score of 10). Higher scores indicate higher level of headache intensity.
Migraine related disability From the baseline to 12 weeks and 24 weeks Migraine related disability measured by the Migraine Disability Assessment Score (MIDAS). The MIDAS consists of five items that reflect the number of days reported as either missing or with reduced productivity at work, home, and social events in last 3 months and two additional items that assess the number of days with headaches in the last 3 months and a scale of the painfulness of the headaches. The MIDAS is scored as the sum of days reported in the first five questions. Higher scores are indicative of more disability.
Stress level From the baseline to 12 weeks and 24 weeks Stress level evaluated by the Perceived Stress Scale-14 (PSS-14). The total score of PSS-14 ranges from 0 to 56 with higher scores indicating higher perceived stress.
Sleep quality From the baseline to 12 weeks and 24 weeks Sleep quality examined by the Chinese version of the Pittsburgh Sleep Quality Index (PSQI). The global score of PSQI ranges from 0 to 21 with a higher score indicating worse sleep quality.
Fatigue level From the baseline to 12 weeks and 24 weeks Fatigue level evaluated by the Numeric Rating Scale-fatigue scale (NRS). NRS evaluates fatigue level at a 0-to-10 scale, with 0 indicating no fatigue and 10 indicating the worst possible fatigue.
Health related Quality-of-Life From the baseline to 12 weeks and 24 weeks Health related Quality-of-Life measured by the Migraine-Specific Quality-of-Life Questionnaire (MSQ). The total scores of MSQ range from 0-100, with a higher score indicating better Quality-of-Life.
Weight From the baseline to 12 weeks and 24 weeks Weight in kilograms
