Eye-Hand Coordination Varies According To Changes In Cognitive-Motor Load And Eye Movements Used, Matthew Alan Yeomans
Eye-Hand Coordination Varies According To Changes In Cognitive-Motor Load And Eye Movements Used, Matthew Alan Yeomans
LSU Doctoral Dissertations
In this dissertation three studies were used to help improve the understanding of eye- hand coordination control of visuomotor reaching tasks with varying cognitive loads. Specifically, we considered potential performance differences based on eye-movements, postural influences, as well as fitness level of the young adult participants. A brief introduction in chapter 1 is followed by a detailed literature review in chapter 2. Results from the three studies presented in chapter’s 3-5 further advance our knowledge of the integrated control used for goal-directed visually-guided reaches. In the first study (chapter 3), the additional cost associated with the use of smooth pursuit …
Geometric Visual Illusion Effects On Visual Perception And Visuomotor Control: Emphasis On The Vertical-Horizontal Illusion, Shijun Yan
LSU Doctoral Dissertations
The focus of this dissertation was to explore the effects of potential vertical-horizontal (V-H) illusory influences on perceptuomotor control. As part of this focus, we examined the potential use of separate cortical visual streams: the ventral visual stream for perception and the dorsal visual stream for action. Three studies were conducted to determine the effects of the V-H illusion influences on length estimations using upper limb point-to-point movements and lower limb stepping movements, involving various illusory configurations, movement directions, gaze directions. After a short introduction (Chapter 1) and a more detailed review of existing literature (Chapter 2), we present manuscripts …
Effects Of Increased Step Width On Knee Joint Biomechanics In Healthy And Knee Osteoarthritis Older Adults During Stair Descent, Maxime Robert Paquette
Effects Of Increased Step Width On Knee Joint Biomechanics In Healthy And Knee Osteoarthritis Older Adults During Stair Descent, Maxime Robert Paquette
Doctoral Dissertations
Stair negotiation is one of the most challenging tasks for older adults especially for those suffering from knee osteoarthritis (OA). To date, no studies have investigated the effects of increased step width (SW) on knee joint biomechanics. The purpose of Study One was to investigate the effects of increased SW on peak internal knee abduction moment and other lower extremity variables during stair descent in healthy older adults. The purpose of Study Two was to investigate the effects of increased SW on peak internal knee abduction moment, knee pain and other lower extremity variables during stair descent in medial compartment …
