This pilot study is designed to validate the diagnostic ability of a novel APD for auricular point detection among patients with menstrual migraine (MMG), as compared with an already commercialized device.
This pilot study is designed to evaluate the diagnostic ability of a novel APD for auricular point detection among patients with menstrual migraine (MMG), as compared with an already commercialized device. The investigators will test if the novel APD could provide a more reliable and quantifiable diagnosis of MMG-related auricular point than traditional devices currently available in the market; The study will also use the APD device to test whether the cutaneous electrical impedance detected from the corresponding auricular points by the novel device is the lowest in the reproductive organ and facial area in the MMG population. As a pilot study, 12 patients with MMG will be recruited from the School of Chinese Medicine, the University of Hong Kong. 12 healthy subjects will be recruited from the university community. Auricular acupoint detection will be accomplished with the new device and a control device. The electrical impedance will be measured and recorded. Patient's condition will also be evaluated by the visual analogue scale (VAS) and the Modified New England Center of Headache (NECH) headache calendar. The specificity and sensitivity of the auricular point detection by the APD device will be calculated. Cohen's kappa coefficient (κ) will be used to test the inter-methods reliability, test-retest reliability, and inter-tester reliability. Moreover, the Pearson Correlation Coefficient will be used to test the correlation between the electrical impedance of the auricular point and the pain intensity score.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| MMG group | Patients in this group will receive auricular point detection which is accomplished by the novel auricular point detector device. There is no addition to the patient's routine care. |

The Modified New England Center of Headache (NECH) headache calendar is a pain diary that can be used to record the time, frequency, intensity and relief of migraine attacks in a month. It employs a 0-10 numeric rating scale (NRS) to quantify the pain intensity of migraine. The frequency and the average pain intensity of menstrual migraine is calculated. |
| baseline |
| self-developed questionnaire on patient's attitude towards complementary therapies for pain management | This is a self-developed questionnaire which includes 10 items aiming to survey patient's attitude towards the use of complementary therapies for pain management. This questionnaire only includes descriptive answers to be choose. The percentage for each choice will calculated. | baseline |
| The diagnostic specificity of the device | The specificity test is a test to validate the ability of a diagnosis to tell the 'non-disease' among those without the disease. | baseline |
| The diagnostic sensitivity of the device | The sensitivity test is a test to validate the ability of a diagnosis to tell the 'disease' among those with the disease. | baseline |
