Why stroke patients avoid using their weak arm: new study investigates
NCT ID NCT04747587
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
After a stroke, many people can move their affected arm but choose not to, a condition called non-use. This study tested 53 participants (stroke survivors and healthy controls) to see how the need for force or precision affects arm use. Researchers used a weight-support system to lighten the arm and measured how often participants actually used it. The goal is to better understand non-use and improve rehabilitation choices.
