Research Focus

My long-term objective is to improve the preparation and performance of whole-body movements in individuals impacted by neurological injury, disease or typical aging processes. 
 
In my laboratory, we use a startling acoustic stimulus to trigger the release of a prepared motor plan. The use of startle to trigger a prepared movement allows us to study motor preparation independent from the other phases of movement. Though we cannot physically observe motor preparation in a clinical setting, this knowledge will inform the development of rehabilitation interventions that target the appropriate phase of movement. 
 
To gain insights into the neural control and biomechanics of human movement, we use electrophysiological techniques and measure movement kinematics and kinetics during the performance of everyday tasks, such as reaching and rising from a seated position.

    Heckman, Rosalind L., Ludvig, Daniel; Perreault, Eric J. Though it has been assumed movement preparation is prerequisite to movement initiation, emerging evidence suggests that the preparation and initiation of movement evolve independently. If movement preparation evolves independent of initiation, then it may be possible for a motor goal to rapidly influence both voluntary movements, those we decide to initiate, and involuntary movements, those triggered in response to external stimuli, such as loud sounds. We show that an accurate movement can be initiated voluntarily or triggered by an external stimulus at similar short latencies following presentation of a motor goal. These findings suggest that the preparation of a motor plan can rapidly influence both voluntary and automatic movements. 2023
