Tai Chi for the Prophylaxis of Episodic Migraine: the Efficacy Examination and Mechanism Exploration

Официальное название

A Randomized Controlled Trail to Examine the Efficacy of Tai Chi for the Prophylaxis of Episodic Migraine Compared With Standard Prophylactic Medication in Chinese Women and a Pre-post Neuroimaging and Laboratory-based Study to Explore the Mechanism of Tai Chi's Intervention Effect

Обзор

The proposed study aims to examine the clinical efficacy of 24-week Tai Chi training in the prophylaxis of episodic migraine comparing with standard prophylactic medication in Hong Kong Chinese women, and to explore the mechanism of Tai Chi's intervention effect by examining the associations of changes in migraine features with neurovascular and neuroinflammation variations.

Подробное описание

A two-arm individual level randomized controlled trial is designed. A total of 220 local women diagnosed with episodic migraine between 18-65 years will be randomly assigned to one of two groups: 1) a Tai Chi training group receiving the 33-short form Yang-style Tai Chi training; or 2) a standard prophylactic medication group receiving the regular medication prescribed by the neurologist. The intervention period will be 24 weeks with another 24 weeks follow-up. The frequency of migraine attack, migraine days, intensity and duration of headache will be recorded by a migraine diary at the baseline, 24th weeks, and 48th weeks. Other outcomes including migraine related disability, stress, sleep quality, fatigue, and QOL will be measured at these three time points. The clinical efficacy will be determined by comparing the differences of outcomes from baseline to the end of the trial between two groups. The MRI and TCD will be used to measure the degree of white matter abnormality and cerebrovascular function, respectively; and the inflammatory markers will also be tested at three time points for Tai Chi participants. The mechanism of intervention effect will be explored by analyzing the changes and associations of migraine features with the process of these neurovascular functions and inflammatory markers during and after the Tai Chi training.

Вмешательства

• Поведенческое Tai Chi training
  The 24-week Tai Chi training will be prescribed with three 1-hour instructor-led sessions and two 1-hour self-practice sessions per week. A modified 33-short form Yang-style Tai Chi Chuan will be adopted. The Tai Chi sessions will be operated by qualified/certified instructors. Each 1-hour training session will consist of 10 minutes brief warm-up stretching session followed by 45 minutes standard Tai Chi routine activities, and 5 minutes of cool-down stretching. The Tai Chi instructors will have
• Препарат Standard prophylactic medication
  Participants assigned to the control group will follow the collaborated neurologist's recommendation, to take the prophylactic medication. The Multidisciplinary Panel on Neuropathic Pain (MPNP) of Hong Kong has published the treatment algorithm for migraine, which is in line with the guideline of the Scottish Intercollegiate Guidelines Network (SIGN) on the pharmacological management of migraine (SIGN 155). Beta-blockers, specifically metoprolol and propranolol, are one of the first-line treatme
