Localization of cortical potentials evoked by balance disturbances
(University of Waterloo, 2011-09-26)The ability to correct balance disturbances is essential for maintaining upright stability. Recent literature highlights a potentially important role for the cerebral cortex in controlling compensatory balance reactions. ... -
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 ... -
Long-term effects of concussion: Investigating the relationship between sensory gating and motor learning
(University of Waterloo, 2023-09-14)Motor learning relies on the sensorimotor system to interpret, adapt, and integrate sensory inputs to guide motor behavior. A key tenet of the somatosensory system is the ability to inhibit irrelevant information from the ... -
Low back pain development differentially influences centre of pressure regularity following prolonged standing
(Elsevier, 2017-06-27)Occupations requiring prolonged periods of static standing are associated with the development of low back pain (LBP). Certain individuals are susceptible to LBP development during prolonged standing (pain developers, PDs) ... -
Lower Limb Biomechanics in Walking, Running and Cycling: Implications for Overuse Injury
(University of Waterloo, 2019-09-27)A common anecdotal theory among endurance athletes is that cycling results in fewer knee injuries compared to running. This is thought to be due in part to a lower impact ground reaction force in cycling, compared to ... -
Lumbar Spine and Hip Kinematics and Muscle Activation Patterns during Coitus: A comparison of common coital positions
(University of Waterloo, 2013-01-31)Qualitative studies investigating the sexual activity of people with low back pain found a substantial reduction in the frequency of coitus and have shown that pain during coitus due to mechanical factors (i.e., movements ... -
The Magnitude and Time Course Effects of an Acute Bout of Moderate Intensity Resistance Training on Cognitive Function
(University of Waterloo, 2016-05-19)Resistance training (RT) is a common form of physical activity that forms a core part of physical activity recommendations. RT has well-documented benefits to metabolic and musculoskeletal health. Emerging research also ... -
Maternal Adaptations and Lipid Mobilization During Pregnancy in Rats
(University of Waterloo, 2017-10-31)Docosahexaenoic acid (DHA) is a major structural fatty acid in brain and is required for fetal growth and development. DHA in maternal plasma increases during pregnancy to meet the placental transport demands of the fetus. ... -
Maternal fish oil supplementation during lactation is associated with reduced height at 13 years of age and higher blood pressure in boys only
(Cambridge University Press, 2016-12-28)Dietary long-chain n-3 PUFA (n-3 LCPUFA) in infancy may have long-term effects on lifestyle disease risk. The present follow-up study investigated whether maternal fish oil (FO) supplementation during lactation affected ... -
Maximal voluntary isometric contraction tests for normalizing electromyographic data from different regions of supraspinatus and infraspinatus muscles: Identifying reliable combinations
(Elsevier, 2018-08-01)This study aimed to identify optimal sets of maximal voluntary isometric contractions (MVICs) for normalizing EMG data from anterior and posterior regions of the supraspinatus, and superior, middle and inferior regions of ... -
Mechanical response of the porcine cervical spine to acute and repetitive anterior-posterior shear
(University of Waterloo, 2011-01-13)Approximately 80% of the population will experience low-back pain within their lifetime. Significant research efforts have focused on compressive loading as an injury mechanism that could lead to low-back pain and injury. ... -
Mechanisms of over-active endothelium-derived contracting factor signaling causing common carotid artery endothelial vasomotor dysfunction in hypertension and aging
(University of Waterloo, 2011-03-09)Background and Purpose: The endothelium is a single-cell layer positioned at the blood-vascular wall interface, where in response to blood-borne signals and hemodynamic forces, endothelial cells act as central regulators ... -
Micronutrients in Long-Term Care (LTC): Issues and opportunities for improvement
(University of Waterloo, 2014-10-22)BACKGROUND: Malnutrition is common among long-term care (LTC) residents, yet there is limited research on micronutrient (vitamin and mineral) malnutrition in the LTC setting. Micronutrient deficiencies may exacerbate ... -
A Model Based Approach to Apraxia in Parkinson's Disease
(University of Waterloo, 2010-05-19)This thesis provides new insight into how learned skilled movements are affected in a disease with basal ganglia damage, within what task demands these deficits can be detected, and how this detection can occur within the ... -
Modeling shoulder ligament contributions and their effects on muscle force predictions
(University of Waterloo, 2008-01-23)Mathematical musculoskeletal modeling and simulation provide a means for proactive injury prevention. To be effective, these models must physiologically replicate shoulder function. Although several muscle force prediction ... -
Modified Texture Diet and Long Term Care: A Secondary Data Analysis of Making the Most of Mealtimes (M3) Project
(University of Waterloo, 2017-01-18)Background: Research has suggested that modified texture diets (MTDs) are prevalent among older adults living in long term care (LTC). Additionally, previous research has also suggested that modified texture food, especially ... -
Modulation of inhibitory and excitatory neural circuits in the primary motor cortex following theta-burst rTMS to area 5
(University of Waterloo, 2010-12-17)Subcortical and cortical loci interact with the primary motor cortex (M1) and influence the neural circuitry mediating hand movement. Area 5 located within the superior parietal lobule has direct connectivity with M1, is ... -
Modulation of sensory processing during simultaneous bimodal stimulation: Effects of sensorimotor integration
(University of Waterloo, 2008-05-23)Illusions such as the McGurk (McGurk and MacDonald, 1976) and ventriloquist (Radeau and Bertelson, 1974) effects or visual capture sensorimotor deficits (Holmes et al., 2004) demonstrate that our perception of and interaction ... -
Modulation of somatosensory cortex underlying error compensation in a tactile speeded-response task
(University of Waterloo, 2014-12-01)There is a lack of empirical evidence that the dorsolateral prefrontal cortex (DLPFC) is exerting control over post-error selective attention adjustments. This is an error compensation mechanism that is hypothesized by the ... -
