Brain zaps and imagination: a new way to boost motor learning in seniors?
NCT ID NCT02813291
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether mentally practicing finger movements (motor imagery) combined with a mild electrical brain stimulation (tDCS) could improve learning of a complex finger sequence in both young (20-35) and older (65-80) healthy adults. 64 participants were split into four groups: young with real stimulation, young with sham (fake) stimulation, older with real stimulation, and older with sham. Over three training sessions and a retention test a week later, researchers measured how many correct sequences each person could perform. The goal was to see if the combination of mental practice and brain stimulation boosts motor learning more than mental practice alone, especially in older adults.
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 non-drug way to help older adults learn or relearn movements, like after a stroke.
What could go wrong
This is a small, early-stage study in healthy people, not patients. The effect may be small or not last long, and brain stimulation can cause mild tingling or discomfort.
