Precise isometric hand grip learning of hemiparetic stroke patients

Rehabilitation of hand movements after stroke aims at skills that can be well
retained and transferred to novel conditions. These functions may be altered by
training schedules such as constant and variable practice.
A total of 36
participants with hemiparesis completed one of these schedules counterbalanced.
Precise isometric hand grip force production was practiced for 4 days with a
target force of 25% maximum voluntary contraction. The constant group practiced
only the target force, whereas the variable group practiced the same amount
including +/-5 and 10% maximum voluntary contraction. Target force presentation
and feedback were provided visually. Results indicated that both practice
schedule led to learning. Variable practice resulted in a superior performance in
retention and transfer tests, suggesting that it may be effective not only in the
healthy population but also in stroke rehabilitation.
