Conditions

weather-related pain

Interventions

Subjects are exposed to a low-pressure environment (atmospheric pressure -40hPa

30min.) that simulates weather disturbances. A smartphone application will then accurately detect changes in pain and changes in autonomic activity induced by lowering barometric pressure, and confirm

Eligibility

Inclusion criteria

Inclusion criteria: All of the following selection criteria must be met. 1) Patients visiting the Pain Center (20-49 years old) who have consented to participate in the study. 2) A person who answered the Weather-Related Pain Checklist and Seven Questions About Weather Dependency to determine if they have a moderate headache as defined and, are affected by bad weather. Those for whom it was confirmed that the pain worsened. 3) Those who are able to participate in one low-pressure exposure experiment according to the schedule specified by the researcher.

Exclusion criteria

Exclusion criteria: Persons who violate any of the following will not be included in this survey. 1) Aichi Medical University student 2) Those who are pregnant or breastfeeding 3) Persons suffering from diseases that must be excluded from research subjects. Diseases not targeted for this research are defined as a secondary headache that does not meet the diagnostic criteria for primary headaches (migraine, tension-type headache, or both) and is caused by another disease or condition. 4) Others (under medication, treatment, etc.) who are deemed unsuitable as participants by the principal investigator and co-investigators.
