One-Hand training may save the other during arm casting
NCT ID NCT07615062
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether training one hand can prevent loss of strength and skill in the other hand when it is immobilized. Healthy young adults will have one arm temporarily immobilized and either do hand exercises with the free hand or not. The goal is to see if cross-education training helps maintain dexterity and strength.
