Friction Testing Of Contemporary Self-Ligating Appliance Systems, Michael Greene
Friction Testing Of Contemporary Self-Ligating Appliance Systems, Michael Greene
Electronic Thesis and Dissertation Repository
Background: Resistance to tooth movement is multifactorial, with friction (FR) one of many important components. There is limited data comparing contemporary Passive and Active self-ligating bracket (SLB) systems in terms of FR created by archwire engagement. Aim: To compare classical FR in contemporary SLB systems and traditional twin brackets in vitro, and to identify the point of initiation of bracket-archwire engagement. Materials & Methods: Nine bracket systems of .022-in slot size were FR tested: Victory Series (3M Unitek) with elastic ligature (control); Passive SLB systems Damon Q (Ormco), Carriere SLX (Henry Schein), H4 (Ortho Classic), Altitude …
An Examination Of Spasticity Of The Lower Extremity Among Young People With Cerebral Palsy, Jordan Nourse
An Examination Of Spasticity Of The Lower Extremity Among Young People With Cerebral Palsy, Jordan Nourse
Honors College Theses
Background: Spasticity is the most common symptom among individuals with Cerebral Palsy (CP). Spasticity is often presented as stiff limbs often resulting in pain. Currently, clinicians are limited in diagnosing spasticity using observational tools. The purpose of this study was compare spasticity at various functional levels using dynamometry. Methods: Participants included nine adolescents (12-19) with CP and nine adolescents (age-matched) without CP. The participants participated in passive stretches delivered by the Biodex System 4 Pro Dynamometer at four different speeds (90, 120, 150, and 180 deg/s), Measurements of the quadriceps will be collected before and during passive knee extension stretches …
Heart Rate Recovery And Blood Pressure Recovery Influenced By A Slow-Breathing Protocol After Exercise In Moderately Trained Females, Emily Layne Zumbro
Heart Rate Recovery And Blood Pressure Recovery Influenced By A Slow-Breathing Protocol After Exercise In Moderately Trained Females, Emily Layne Zumbro
Electronic Theses and Dissertations
Heart rate (HR) and blood pressure (BP) increases in order to meet metabolic demands as a result of exercise primarily through way of the sympathetic nervous system (SNS) and parasympathetic nervous system (PNS). This study aimed to build on previous research in finding the best method to rapidly decrease HR and BP after exercise during the recovery period. PURPOSE: The purpose of this study was to determine the effectiveness of a breathing technique on HRR and BPR within a healthy female population during an exercise recovery period compared to active recovery and upright passive recovery. METHODS: Nine moderately trained female …
