Effects Of Head Position And Head-Supported Mass On Nerve Function Of The Flexor Carpi Radialis Muscle In Healthy Individuals, Bethany Lauren Shivers

Graduate Theses and Dissertations

Long-term exposure to head-supported mass (HSM) has been linked with spinal degeneration including foraminal stenosis and disc deterioration. Anecdotally, HSM has also been linked to neck and arm pain and muscle atrophy, but nerve function has not been tested specifically. The combined effect of various head positions and HSM may be sufficient to compress the nerve root in aviators and Soldiers during job performance, potentially leading to short- and long-term neuromuscular effects. The Hoffmann (H) reflex, a well-established measure of nerve function, has shown to be sensitive to changes in nerve root space which occurs with different head positions. This …

Path Integration: Effect Of Curved Path Complexity And Sensory System On Blindfolded Walking, Panagiotis Koutakis, Mukul Mukherjee, Srikant Vallabhajosula, David J. Blanke, Nikolaos Stergiou

Journal Articles

Path integration refers to the ability to integrate continuous information of the direction and distance traveled by the system relative to the origin. Previous studies have investigated path integration through blindfolded walking along simple paths such as straight line and triangles. However, limited knowledge exists regarding the role of path complexity in path integration. Moreover, little is known about how information from different sensory input systems (like vision and proprioception) contributes to accurate path integration. The purpose of the current study was to investigate how sensory information and curved path complexity affect path integration. Forty blindfolded participants had to accurately …

Physical Activity Behaviour Of Paediatric Patients With Type 1 Diabetes, Freya Macmillan, Alison Kirk, Nanette Mutrie

International Journal of Exercise Science: Conference Proceedings

Type 1 diabetes is a common chronic condition in children and young people and its prevalence is increasing worldwide. Paediatric patients with Type 1 diabetes can have poorer health and overall quality of life than their non-diabetic peers and some studies suggest that they may be less active than their non-diabetic peers. Regular physical activity has many potential health benefits for any young person but can also benefit areas of health specifically important for those with Type 1 diabetes. In addition being regularly active can reduce the risk of developing diabetic complications. Promoting physical activity participation in this population is …

Health and Kinesiology Faculty Publications

• What is the central question of this study?

  In human arteries involved in the regulation of muscle blood flow, there is a lack of data about whether acidosis alters vascular sensitivity to vasoactive agents, as well as altering endothelium dependent vasorelaxation. Little is known about the interaction of metabolites and vascular function in human skeletal muscle feed arteries.

• •

  What is the main finding and its importance?

  Increasing acidosis attenuated the response and sensitivity of the arteries to phenylephrine; this effect was selective to the receptor over smooth muscle.

  Acidosis did not alter endothelium dependent vasorelaxation. Impaired vasoconstriction coupled with …

A Comparison Of Two Tape Techniques On Navicular Drop And Center Of Pressure Measurements, Krista M. Prusak

Theses and Dissertations

Introduction: Foot over-pronation, attributable to Tibialis Posterior (TP) muscle weakness, is a possible cause of medial tibial stress syndrome (MTSS)3. Taping may provide a viable alternative for a dysfunctional TP and its associated navicular drop (ND). The most commonly used Augmented LowDye (ALD) technique has shown to prevent ND, but is time- and cost- intensive, leading us to explore an alternative technique. The purpose of this study was to assess the effectiveness of a new, anti-pronation (AP) taping technique, as compared to the ALD, to (a) reduce or prevent ND and (b) cause a lateral shift in the center of …
