Evaluation of a Device to Reduce Motion Sickness and Spatial Disorientation
NCT06892340 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this research study is to learn how a wearable nerve stimulation device, the Spark Biomedical's Sparrow Ascent System™, impacts the development of spatial disorientation and/or motion sickness in a healthy population. Spatial disorientation is when there is a "mismatch" between where a person is, and where the sense organs in their body tell them where they are. These sense organs include the inner ear (the vestibular system), the eyes (the visual system), the sense of where one's legs, back, and neck are (proprioceptive system), and one's higher thinking (cognitive centers). If spatial disorientation is severe or occurs in motion-naïve individuals, spatial disorientation can lead to motion sickness. The Sparrow Ascent System™ is a wearable, battery-operated transcutaneous auricular (ear) neurostimulation (tAN) device. This means that it uses electrical pulses to stimulate branches of nerves on and/or around the ear, specifically the "vagus" and "trigeminal" nerves. These nerves are also responsible for your sensation of nausea and your heart rate (vagus nerve), as well as headaches (trigeminal nerve). The Sparrow System utilizes a flexible earpiece with embedded hydrogel electrodes that stick to the skin, the earpiece is disposable after use. This device is already Food and Drug Administration (FDA) approved for use in humans and is safely used for control of symptoms in a variety of other medical conditions, such as opioid withdrawal and acute stress reaction. In this study, we will determine if the Sparrow Ascent System™ impacts the development of spatial disorientation or motion sickness.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06892340
The ClinicalTrials.gov registry entry for NCT06892340 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 36 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is 59th Medical Wing, which has 7 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Motion Sickness appearing as the primary indexed condition, and to 1 intervention — of which Transcutaneous Auricular Neurostimulation device is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06892340 reports 1 study location spanning 1 distinct geographic area — top geographies include Texas. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
