Christopher K. Rhea

Dr. Christopher K. Rhea is an Assistant Professor in the Department of Kinesiology at the University of North Carolina at Greensboro. He serves as the director of the Virtual Environment for Assessment and Rehabilitation Laboratory (VEAR Lab) and teaches courses in biomechanics and movement variability. Dr. Rhea received his B.S. in Physical Education from the University of Central Missouri (2002), M.S. in Movement Science specializing in sports biomechanics from Barry University (2004) and Ph.D. in Motor Behavior specializing in biomechanics from Purdue University (2009). His primary research interest is the control of locomotion. One line of research in the VEAR Lab consists of developing and applying assessment techniques derived from nonlinear dynamics to evaluate locomotor behavior before and after injury. The primary clinical population of interest is those with a torn anterior cruciate ligament (ACL).

TitleDateViewsBrief Description
Control of adaptive locomotion: effect of visual obstruction and visual cues in the environment 2006 160 Visual information regarding obstacle position and size is used for planning and controlling adaptive gait. However, the manner in which visual cues in the environment are used in the control of gait is not fully known. This research examined the eff...
Locomotor Adaptation versus Perceptual Adaptation when Stepping Over an Obstacle with a Height Illusion 2010 232 Background During locomotion, vision is used to perceive environmental obstacles that could potentially threaten stability; locomotor action is then modified to avoid these obstacles. Various factors such as lighting and texture can make these envir...
Multiple timescales in postural dynamics associated with vision and a secondary task are revealed by wavelet analysis 2009 476 Discrete wavelet analysis is used to resolve the center of pressure time series data into several timescale components, providing new insights into postural control. Healthy young and elderly participants stood quietly with their eyes open or closed ...
Noise and complexity in human postural control: interpreting the different estimations of entropy. 2011 161 BACKGROUND: Over the last two decades, various measures of entropy have been used to examine the complexity of human postural control. In general, entropy measures provide information regarding the health, stability and adaptability of the postural s...
Visual exteroceptive information provided during obstacle crossing did not modify the lower limb trajectory 2007 343 The roles of visual exteroception (information regarding environmental characteristics) and exproprioception (the relation of body segments to the environment) during gait adaptation are not fully understood. The purpose of this study was to determin...
