Gentle noise stimulator to improve balance and walking in older adults
Improvements in Balance and Gait Using a Stochastic Noise Stimulator: Short Term Response
This test will try a gentle, sub‑sensory electrical noise device (like a TENS) to see if it immediately improves balance and walking speed in older adults with reduced balance.

What this trial studies
Participants will wear a small electrical stimulator that delivers subperceptual stochastic noise to the vestibular system and will be compared with a sham (no effective stimulation). During sessions participants perform a 6‑minute walk, standing balance tests with eyes open and closed on firm and foam surfaces, and a tilting chair protocol while eye movements are recorded. The primary outcome is immediate change in walking speed, with secondary outcomes including measures of postural sway and vestibular-related eye movements. The study enrolls older adults (60+) and younger adults (21–59) to characterize age-related responses and device effects.
Who should consider this trial
Good fit: Ideal candidates are adults with reduced balance function—particularly older adults aged 60 and over—who can stand unassisted for 30 seconds and walk for 6 minutes and do not have major medical exclusions.
Not a fit: People with implanted electronic devices, uncontrolled cardiovascular or neurologic conditions, severe eye problems, uncontrolled diabetes, recent substance abuse, or inability to stand or walk unassisted are unlikely to qualify or benefit from this device.
Why it matters
Potential benefit: If successful, the device could provide a non-invasive, immediate way to improve balance and walking speed and potentially reduce fall risk in older adults.
How similar studies have performed: Previous lab work has linked age-related vestibular decline to balance problems, and smaller proof-of-concept studies of vestibular noise stimulation have suggested immediate balance improvements, but large-scale clinical benefit remains unproven.
