UNG professor Dr. Andrzej Przybyla has co-authored a paper examining the relationship between reaction times and hand dominance to better understand how to aid in the rehabilitation of stroke patients.



Dr. Andrzej Przybyla, professor of physical therapy at the University of North Georgia (UNG), recently co-published a research paper whose findings could impact rehabilitation after stroke. The study examined the impact of restricting movement preparation time on hand selection decisions during reaching.

“Rehabilitation is more productive when we modify human behavior. A better understanding of the neural mechanisms underlying hand-selection behavior can aid in the development of new therapeutic interventions and clinical tools to monitor the effects of therapy on changes in human motor behavior,” Przybyla said.

In this study, healthy participants performed focused effort on the horizontal workspace with hand choice or no hand choice in a reaction time task. While previous studies provided ample time for hand selection, this study required participants to initiate the hand movement immediately after the target presentation.

Przybyla said testing healthy participants is the first step in this line of translational research. Future efforts will focus on translating this reaction time hand selection paradigm to study behavioral changes of motor decisions in chronic stroke patients.

The study helps to understand the motor behavior of manual selection and how it might be changed in a predicted way. This knowledge can lead to the development of new interventions and diagnostics in physiotherapy and rehabilitation.

Przybyla thanked UNG President Bonita C. Jacobs for supporting her efforts in this project through a Presidential Semester Incentive Award.

“This is great and much appreciated support for research and development,” he said. “Having the opportunity to focus more effort helps in professional development and could lead to the development of new projects, as well as dissemination in a respected manner
