Non-invasive Nerve Stimulation and Sleep
NCT04021537 · View on ClinicalTrials.gov ↗
Study Summary
People often have difficulty sleeping. Reasons are many. But, difficulty falling and staying asleep are common issues. Sleep difficulties are common in disorders such as Post Traumatic Stress Disorder. Current treatments for sleep difficulties are not effective for everyone. Better treatments are needed. In this study, the investigators are testing two nerve stimulation locations that may impact brain function in such a way that sleep is improved.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04021537
The ClinicalTrials.gov registry entry for NCT04021537 describes a study currently listed as active not 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 87 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is VA Office of Research and Development, which has 1,863 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 PTSD appearing as the primary indexed condition, and to 1 intervention — of which non-invasive nerve stimulation 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: NCT04021537 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. 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.
