Strengthening the less-impaired arm helps stroke survivors regain hand function, a new study finds.
A new study published in JAMA Neurology on February 2, 2026, finds that stroke survivors can significantly improve daily hand function by strengthening their less-impaired arm, challenging traditional rehab focused only on the affected side.
Researchers at Penn State studied over 50 chronic stroke patients who trained either their more or less impaired arm for five weeks using goal-directed exercises, including virtual reality tasks.
Those who trained their less-impaired arm showed greater gains in speed and efficiency, with benefits lasting at least six months.
The results suggest that improving function in the typically overlooked arm can lead to better coordination, reduced fatigue, and increased independence, offering a promising new approach to long-term stroke recovery.
