ClinConnect Summary

The study involved 40 participants, half of whom had suffered a stroke with hemiparesis and the other half a control group of healthy volunteers. During the experimental session, the participants have to perform a motor task involving reaction speed. A box with two buttons (right and left) is placed in front of the participant. The participant's hands are placed in the box under the buttons. The experimental task is to press one of the two buttons by extending the fingers in response to a visual stimulus - lamps above the buttons. If the degree of damage to the motor function of one of the ...
