Wininger Invited to Nation’s Top-ranked Kinesiology Program to Speak about Measuring Motor Skill

Mike Wininger, assistant professor in ENHP’s Department of Rehabilitation Sciences, delivered a colloquium at Pennsylvania State University on January 11, 2013.  The invitation to share his research came from the Department of Kinesiology’s Action Club which draws speakers from around the world to talk about human motor control.   Michael Wininger

Wininger describes the presentation:  Measuring motor skill is an integral aspect of our work as clinicians and researchers. We typically assume that movement smoothness is the best way to objectively measure skill, but we as a community lack a robust measure of smoothness. One widely used smoothness measure, that of “integrated jerk” while used successfully in many studies, occasionally reveals a counter-intuitive behavior. In my talk, I identify one possible reason for this failure, namely that integrated jerk is posed as a function of time, which is a poorly controlled variable, and on which integrated jerk is highly (and spuriously!) correlated. I propose that re-formulating integrated jerk as a function of joint angle may be a suitable alternative. This presentation highlights previously published works including Wininger, J Biomechanics 2009, and Wininger, J Motor Behavior 2012.
