Orthostasis

Participants who meet the inclusion/exclusion criteria in the Screening visit are randomly assigned 1:1 to the treatment group or the sham control group. The two-week period after Screening is the Run-in period, and the participant performs self-measured blood pressure monitoring, records data using the One.Dr application, and records symptoms and events related to orthostatic hypotension such as dizziness in the application. Only those who have completed the Run-in period will enter the Intervention period (for 6 weeks at 3-8 weeks), and according to each allocation group, non-pharmaceutical treatment education is provided for the treatment group and general health knowledge education is provided for the sham control group.
