Lower insomnia scores with electrical vestibular stimulation
A small review of sham-controlled trials found better questionnaire scores, but leaves uncertainty about practical benefits, consistency and safety.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Adults with clinically significant insomnia reported greater improvement in symptom severity with electrical vestibular nerve stimulation than with sham stimulation. Sleep quality scores also improved. This abstract-based review suggests a signal worth investigating, but does not establish how noticeable the changes were in daily life or whether the approach is ready for routine use.
The evidence came from few trials, relied on subjective measures and showed considerable variation between studies. Safety information was limited, leaving uncertainty about both consistency and potential harms.
What researchers found
Mean difference in Insomnia Severity Index change
Electrical vestibular nerve stimulation versus sham; assessment timing was not reported.
What participants reported
The primary endpoint was a questionnaire about insomnia severity. Sleep quality and quality of life were secondary outcomes, also collected through self-reports, so the results describe participants' reported experiences.
Which outcomes improved
The abstract reports statistically significant differences in insomnia severity and sleep quality. It does not report a quality-of-life result, so an improvement in that outcome cannot be assumed from the sleep scores.
