A Laboratory Study on the Effect of Helmet Fit on Biomechanical Measures of Head and Neck Injury in Simulated ImpactDownload
Conventional wisdom and the language in international helmet testing and certification standards suggest that appropriate helmet fit and retention during an impact are important factors in protecting the helmet wearer from impact-induced injury. This thesis aims to investigate impact-induced...
Application of a biomechanical finite element spine model to the vicious cycle scoliosis growth theory: evaluation of improved FEA geometry and material assignmentDownload
Scoliosis is defined as the abnormal three dimensional curvature of the spine with 80% of all cases being idiopathic in nature. If left unchecked, this condition can cause cardio-pulmonary complications and occasionally death. Currently, the most common method of treatment of scoliosis is through...
The objective of this thesis was to biomechanically examine the potential usage and limitations of a suspended aid for practicing circles on a pommel horse. The first study examined the influence of a suspended aid on the pommel reaction forces. Twenty gymnasts performed three sets of 10 circles...
Sit-to-stand transfer (STS) is a common yet critical prerequisite for many daily tasks. Literature conducted on healthy STS often assume the body to behave symmetrically across the left and right side; yet only a few studies have been conducted to investigate this supposition. These studies have...
Research to help prevent or alleviate the muscle fatigue and injuries prevalent among long-term manual wheelchair users is largely conducted in a laboratory environment. Through laboratory simulations it is possible to focus on a manageable set of variables among the many pertinent ones that...
Various X-ray imaging modalities, such as planar X-ray films, dual energy X-ray absorptiometry and computed tomography have been utilized to estimate bone strength for osteoporotic subjects. However, emerging cases of spontaneous femoral shaft fracture in osteoporotic patients after years of...
Development and Characterization of a Mechanical Surrogate Neck Prototype for Use in Helmet Certification ApplicationsDownload
Sport activities account for over half of all injuries in youths and young adults, with head injuries consistently ranked in the top five most common injury types. Despite mandated helmet use, contact sports, such as hockey and football, expose the players to a greater risk of suffering head and...
Introduction: Expertise in motor skill develops through continued practice. Repetition of a task can lead to overall performance improving as well as an increase in the efficiency and effectiveness of a movement. Golf putting is an example of one such task that needs to be practiced in order to...
The objective of this research was to study the work performed and distribution of work across the lower extremity in various landing tasks. Ten women performed jump landing and weightlifting tasks recorded in a motion analysis laboratory. Joint angles and moments were determined, from which...
FEM Simulation of Non-Progressive Growth from Asymmetric Loading and Vicious Cycle Theory: Scoliosis Study Proof of ConceptDownload
Scoliosis affects about 1-3% of the adolescent population, with 80% of cases being idiopathic. There is currently a lack of understanding regarding the biomechanics of scoliosis, current treatment methods can be further improved with a greater understanding of scoliosis growth patterns. The...
