The University of British Columbia Magazine recently featured Robyn Freiheit (BKin’15) and her experiences of living and working abroad in Portugal.
Robyn has been living in Porto for the past four years, where she works as a freelance marketing, communications and project management specialist, and serves as the alumni UBC Global Alumni Ambassador for Portugal.
Many of our actions are triggered by changes in the environment and most of these actions can be prepared in advance of the anticipated change. When human action is observed in these reactive situations one may be oblivious to the fine synchronization that is required between movement preparation, initiation and execution and yet each is vital to the effective control of action. Success and failure of these processes are evident in many everyday situations. From the Olympic sprinter who prepares for a fast start out of the blocks in elegant smooth pursuit of their goal, to the Parkinson’s disease patient who fails to initiate a seemingly simple step over a roadside curb and freezes despite what appears to be maximum cognitive effort. In our lab we examine how people prepare, initiate and control their actions in various environmental contexts using a variety of methodologies. One method we have used to good effect in the past is to probe the processes of movement preparation by delivering a startling stimulus along with the “go” command. This brief loud sound causes a startle reflex but also appears to trigger and release any voluntary movement that is prepared, stored and ready to initiate. Indeed very fast reaction times of the sprinter (less than 100 milliseconds) may be the result of a startle like trigger and not a false start. We have also shown that startle can trigger prepared movements quite smoothly and effortlessly in patients with Parkinson’s disease. Because we have an understanding of the pathways responsible for the startle reflex it then becomes possible to map movement preparation and initiation as it interacts with this reflex. In the future, we will to continue our research efforts into the investigation of motor preparation and initiation using techniques such as startle.

I am an integrative physiologist with a primary focus on how the cardiovascular and pulmonary systems respond to spinal cord injury. I conduct research across the translational spectrum including in rodents, pigs, the clinical spinal cord injury population, and with Paralympic athletes. I run the Translational Integrative Physiology Laboratory located at the Blusson Spinal Cord Center. This Center houses the International Collaboration on Repair Discoveries, a collection of over 300 individuals working to improve the lives of people with spinal cord injury. My laboratory is supported by an infrastructure grant from the Canadian Foundation for Innovation and the British Columbia Knowledge Development Found. I hold competitive operating funding from the Heart and Stroke Foundation of Canada, The Rick Hansen Institute, and the Craig Neilsen Foundation. In my work with the clinical spinal cord injury population, I have begun the first trial investigating the acute (within 12hr) cardiac responses to spinal cord injury, which involves assessing cardiac function during and following spine surgery. In my work with athletes, I have been part of an International Cardiovascular Health Clinic at the London2012 Paralympics, Socchi 2014 Paralympics and a number of world-championships events. In my pre-clinical experimental work, I combine state of the art cardiac imaging (MRI and high-frequency ultrasound) with invasive preparations (closed-chest cardiac pressure-volume loops) and standard bench techniques (molecular and histological approaches) to better understand how the heart responds to spinal cord injury and what mechanisms underlie the responses.
The $1.53 million award will fund the development of the RESPECT Collaboratory, a facility that is designed for building, assessing, and evaluating physical activity initiatives developed for hard-to-reach populations.
The RESPECT Collaboratory will position UBC and the School of Kinesiology as world leaders in physical activity research that focuses on hard-to-reach populations.
Congratulations to Dr. Faulkner and his team on this outstanding achievement!
