Brain zaps may steady shaky steps in seniors
NCT ID NCT06008431
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a non-invasive brain stimulation technique called tDCS could improve walking steadiness in 27 older adults at risk of falling. Participants received both real and sham stimulation while their gait and brain activity were measured. The goal was to see if targeting specific brain networks could reduce the variability in their stride, which is a known predictor of falls.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial direct current stimulation (tDCS)
- What this could lead to
- If it works, this could point toward a safe, non-drug way to improve walking stability and reduce falls in older adults.
- What could go wrong
- This was a very small, early-stage study (27 people) with no long-term follow-up. The results may not apply to everyone, and the effect may be too small to matter in daily life.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aged 65 and above. * Ability to speak and read English. * Ability to walk independently and continuously for at least 1 minute. * Elevated gait variability as defined by a coefficient of variation (CoV) about average stride time larger and equal to 0.025 during straight-line walking at preferred speed. Exclusion Criteria: * More than mild cognitive impairment defined by a Montreal Cognitive Assessment (MoCA) score less than 18. * Parkinson's disease, multiple sclerosis, stroke, active brain tumor, or other neurological disorders. * Self-reported pain or lower extremity deformity that significantly disrupts walking. * Contraindications to MRI or tDCS. * An episode of acute illness or exacerbation of a diagnosis that requires hospitalization or active treatment within the past 3 months. * Current treatment for congestive heart failure, angina, uncontrolled arrythmia, deep vein thrombosis, or other uncontrolled cardiovascular events. * Myocardial infarction, coronary artery bypass grafting, angioplasty, or other cardiac conditions within the past 3 months, * Active cancer for which chemo/radiation therapy is being received. * Psychiatric co-morbidity including major depressive disorder, schizophrenia, psychosis, or other psychiatric illness. * Recent use of any sedating medications (sedatives, anti-psychotics, hypnotics, anti-depressants) or change in medication within the previous month. * Chronic vertigo or other diagnosed vestibular disorders. * Legal blindness, visual impairments that cannot be corrected with glasses, contact lenses, medicine, or surgery. * Those without WiFi access * Those who do not plan to live in their current homes for the duration of the study
