Central Nervous System Control of Dynamic Stability during Locomotion in Complex Environments
(University of Waterloo, 2006)A major function of the central nervous system (CNS) during locomotion is the ability to maintain dynamic stability during threats to balance. The CNS uses reactive, predictive, and anticipatory mechanisms in order to ... -
Determinants And Strategies For The Alternate Foot Placement
(University of Waterloo, 2005)Undesirable landing area (e. g. , a hole, a fragment of glass, a water puddle, etc) creates the necessity for an alternate foot placement planning and execution. Previous study has proposed that three determinants are ... -
The Dilemma of Proxy-Agency in Exercise: a Social-Cognitive Examination of the Balance between Reliance and Self-Regulatory Ability
(University of Waterloo, 2005)Social Cognitive Theory (SCT: Bandura, 1997) has been used successfully in understanding exercise adherence. To date, the majority of the exercise research has focused on situations of personal agency (i. e. , self ... -
The Effects of 60 Days of Head Down Bed Rest on Vascular Health
(University of Waterloo, 2006)This study was designed to test the hypothesis that 60 days continuous head down bed rest (HDBR), an Earth-based analogue of the effects of space flight, would elevate factors that increase vasoconstriction and would ... -
An examination of glove attributes and their respective contributions to force decrement and increased effort in power grip at maximal and submaximal levels
(University of Waterloo, 2006)Gloved work has been shown to increase the effort required to perform manual tasks. In power grip tasks, these differences have been observed as reductions in strength and increases in muscular effort. Decreases in ... -
An Identity Theory and Social Cognitive Theory Examination of the Role of Identity in Health Behaviour and Behavioural Regulation
(University of Waterloo, 2005)The self has been identified as the ?psychological apparatus that allows individuals to think consciously about themselves? (Leary & Price Tangney, 2003, p. 8). Further, the self has been identified as a worthwhile ... -
Locating Instability in the Lumbar Spine: Characterizing the Eigenvector
(University of Waterloo, 2006)Overloading of the back can cause instability such that buttressing the instability is a primary objective of many of the leading edge therapeutic approaches. However, a challenge lies in determining the location of the ... -
Progressive Disc Herniation: An investigation of the mechanism using histochemical and microscopic techniques
(University of Waterloo, 2006)Abstract Background: The process that involves the migration of the nucleus pulposus from the innermost annular layers and culminates with the final extrusion of the nucleus has been limited to a few studies. This ... -
Protective Responses during a Sideways Fall: Effects of Secondary Tasks
(University of Waterloo, 2006)Falls and hip fractures are a major public health problem among the elderly. In addition to bone strength, sideways falls and direct hip impact are important determinants for hip fracture. However, few falls actually ... -
Self-efficacy theory and the self-regulation of exercise behaviour
(University of Waterloo, 2005)Why are people unable to adhere to an exercise program? Adhering to an exercise program is complex, and exercisers struggle with a variety of challenges that require self-regulation (e. g. , making time, learning skills, ... -
Stabilization Strategies of the Lumbar Spine in Vivo
(University of Waterloo, 2002)In developing a method of quantifying stability in the lumbar spine Cholewicki and McGill (1996) have also broached the notion of sufficient stability, where too much stiffness (and stability) would hinder motion. Thus ... -
VISUAL INPUTS AND MOTOR OUTPUTS AS INDIVIDUALS WALK THROUGH DYNAMICALLY CHANGING ENVIRONMENTS
(University of Waterloo, 2006)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ...
