Health Promotion Initiative For Booster Seats: A School-Based Educational Intervention., Jody Ann. Mcginnis
Health Promotion Initiative For Booster Seats: A School-Based Educational Intervention., Jody Ann. Mcginnis
Electronic Theses and Dissertations
The purpose of this study was to investigate the effect of a booster seat educational intervention on the purchasing/obtainment behavior of parents. A quasi-experimental methodology was utilized, including an educational seminar for parents and their children. Data analysis combined a mixed factorial ANOVA, with one between subjects factor (group; intervention vs. control) and one within subjects factor (session; pretest vs. post-test). Pre-test and post-test scores were examined related to the dependent variables of use and obtainment. Analysis of differences in retention of information and child's cooperation using the booster seat were also examined as independent variables. Findings support the development …
Vehicle Restraint Of The Young Child., Annette Marie. Scott
Vehicle Restraint Of The Young Child., Annette Marie. Scott
Electronic Theses and Dissertations
Outcomes of childhood trauma related to motor vehicle crashes (MVCs) have remained unchanged over the past 30 years. In addition, trauma related injuries are responsible for 50% of all childhood deaths (Block, Hanson, & Keane, 1998; Patterson, 1999). Child vehicle restraint studies indicate that children 4 to 9 years of age may be at greater risk of MVC injury than other age groups. Booster seat research is largely lacking, and most children do not meet the physical guidelines for seat belt use until 9 or 10 years of age (Weber, 2000). The purpose of this study was to examine vehicle …
The Effects Of Trunk Muscle Fatigue And Load Timing On Spine Mechanics During Sudden Hand Loading., Diane Eva. Grondin
The Effects Of Trunk Muscle Fatigue And Load Timing On Spine Mechanics During Sudden Hand Loading., Diane Eva. Grondin
Electronic Theses and Dissertations
Sudden loading of the trunk, especially when it is unexpected, leads to higher muscle forces. Muscle fatigue, on the other hand, decreases the force producing capacity of muscles. The current experiment provides insight into the control of spine mechanics during trunk muscle fatigue in a situation of sudden loading that affects spinal stability. Fifteen females received a sudden load in the hands, at a time that could be anticipated and at a time that could not. Participants received these loading trials (a) while rested, (b) with back muscle fatigue, and (c) with a combination of back and abdominal muscle fatigue. …
A Biomechanical Model Of The Spine To Predict Trunk Muscle Forces: Optimizing The Relationship Between Spinal Stability And Spinal Loading., Stephen Hadley Morgan Brown
A Biomechanical Model Of The Spine To Predict Trunk Muscle Forces: Optimizing The Relationship Between Spinal Stability And Spinal Loading., Stephen Hadley Morgan Brown
Electronic Theses and Dissertations
The purpose of this study was to develop an optimization model of the spine that, incorporating a measure of spinal stability as a constraint, allowed for realistic predictions of trunk muscle and spine compression forces. A 3-dimensional, 52 muscle, single joint model of the lumbar spine was developed and tested in situations of pure trunk flexor and lateral bend moments. Spinal stability, about each anatomical axis, was calculated at the L4/L5 spinal joint. Estimates of the optimal level of spinal stability, in a given loading situation, obtained through the use of regression equations developed from experimental findings, were utilized as …
Two-Dimensional Measurements Of Dynamic Cumulative Spine Loading In Real-Time., Michael James. Agnew
Two-Dimensional Measurements Of Dynamic Cumulative Spine Loading In Real-Time., Michael James. Agnew
Electronic Theses and Dissertations
The purpose of this study was to develop a real time method for documenting the cumulative low back loads present in lifting tasks using a simplified regression based biomechanical model. Following model development, custom software was created and used with an electromagnetic tracking device (Fastrak(TM)) to calculate cumulative loads in real-time. Estimates obtained from the real-time method (cumulative joint compression, anterior joint shear, posterior joint shear) were compared to estimates from a dynamic link segment biomechanical model (GOBER). Estimates obtained by the real-time method were statistically different than the dynamic biomechanical model in estimates of cumulative compression and cumulative anterior …
