- Brief Summary
The proposed study aims to preliminarily test the effects of a 12-week Tai Chi training on the prophylaxis of episodic migraine in Chinese women, and to evaluate the feasibility, acceptability, compliance and maintenance of Tai Chi exercise among this population.
- Detailed Description
Migraine is a disabling neurological condition, characterized by attacks of headache and associated symptoms such as photophobia, nausea, and vomiting. In Hong Kong, the overall prevalence is around 12.5%. People with repeated migraine attacks are pain and personal suffering, have impaired social and personal life, and increased financial cost of medication. More nonpharmacologic prophylactic treatments are needed to reduce the high disease burden. As a body-mind exercise, Tai Chi's potential therapeutic efficacy on the prophylaxis of migraine has caught our attention. The investigators propose to conduct a two-arm individual level randomized controlled trial. Local women diagnosed with episodic migraine between 18-65 years will be randomly assigned to one of two groups: 1) a Tai Chi training ("TC"); or 2) a waiting list control group ("control"). The control group will receive a "delayed" Tai Chi training at the end of the trial. A total of 60 participants will be randomized and the intervention period will be 12 weeks with another 12-week follow-up. Number of attacks per month (frequency of attack), intensity and duration of headache, stress, sleep quality and quantity, fatigue, HRQoL, and body composition will be measured at baseline and at 12 weeks and 24 weeks. The primary outcomes are the difference in frequency of attack from baseline to the 12 weeks after randomization, and the proportion of patients with at least a 50% reduction of the number of attacks per month. The intervention effect will be estimated by calculating the differences of outcomes from baseline to the end of the trial between the intervention and control groups using intention-to-treat analysis.

Group Intervention Description Tai Chi training Tai Chi training The participants in this arm will receive 12-week Tai Chi training (1 hour per day, 5 days per week). Waiting list control group Waiting list control group Participants in this arm will be asked to maintain their usual lifestyles and exercises for 12 weeks. At the end of the trial , the participants will be offered Tai Chi training similar as Tai Chi group.
- Primary Outcome Measures
Name Time Method The proportion of responders From baseline to 12 weeks Defined as the proportion of patients with at least a 50% reduction of the number of attacks per month
The difference in frequency of migraine attacks (the number of attacks per month) From baseline to 12 weeks
- Secondary Outcome Measures
Name Time Method Hip circumference From baseline to 12 weeks and 24 weeks Hip circumference in cm
Intensity of headache From the baseline to 12 weeks and 24 weeks Intensity of headache will be measured by a Visual Analogue Scale.
Waist circumference From the baseline to 12 weeks and 24 weeks Waist in cm
Percent body fat From the baseline to 12 weeks and 24 weeks Session attendance rate From baseline to 12 weeks Number of participants who truly attend the Tai Chi training session divided by the total number of participants in that training session
Adverse events During intervention period (12 weeks) Sleep quantity From the baseline to 12 weeks and 24 weeks A 7-day daily sleep log will be used to measure the sleep quantity.
Height From the baseline to 12 weeks and 24 weeks Height in meters
Duration of headache attack From the baseline to 12 weeks and 24 weeks Stress status From the baseline to 12 weeks and 24 weeks The Perceived Stress Scale (PSS) will be used to measure the stress level.
The percentage of the participants in the intervention group who keep Tai Chi exercise for 1 time per week and last 6 weeks in the 12-week follow up period 12 weeks after Tai Chi training This is to measure the maintenance of Tai Chi practice
Participation rate At baseline assessment (4 weeks) This outcome is measured by the eligible participants at baseline assessment divided by the subjects who register the study
Sleep quality From the baseline to 12 weeks and 24 weeks The Chinese version of the Pittsburgh Sleep Quality Index (PSQI) will be used to measure the sleep quality.
Fatigue level From the baseline to 12 weeks and 24 weeks The Numeric Rating Scale-fatigue (NRS-fatigue) will be used to measure fatigue level.
HRQoL From the baseline to 12 weeks and 24 weeks HRQoL will be measured by using the Chinese version of the SF-36.
Weight From the baseline to 12 weeks and 24 weeks Weight in kilograms
The number of weeks the participants in intervention group practice Tai Chi at least one time per week in the 12-week follow up period 12 weeks after Tai Chi training This is to measure the maintenance of Tai Chi practice
Dropout rate From the baseline to 12 weeks and 24 weeks Number of participants successfully complete the 12-week Tai Chi training and 12-week follow up divided by the number of participants at baseline
