Can a Thigh-Worn sensor outsmart dizziness questionnaires?

NCT ID NCT04782830

First seen Jul 02, 2026 · Last updated Jul 02, 2026

Summary

This study explores whether a small accelerometer worn on the thigh can objectively measure how well treatments work for neurogenic orthostatic hypotension—a condition causing dizziness and fainting upon standing. Participants wear the device for one week on placebo and one week on their usual medication (midodrine or atomoxetine). The goal is to see if upright time measured by the device matches or outperforms symptom questionnaires in assessing treatment effectiveness.
