Brain scans reveal how effort changes arm movement after stroke
NCT ID NCT06116006
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at brain activity in 64 people (some who had a stroke and some healthy) while they moved their arms with different levels of effort. The goal was to understand how the brain responds during rehabilitation exercises. Researchers used a special brain scanner (fNIRS) to measure changes in oxygen levels in the brain during the tasks.
