The Natural History Of Modic Changes - A 5- And 15-Year Follow-Up Study, Parnian Saremi

Electronic Thesis and Dissertation Repository

Modic changes (MCs), defined as bone marrow lesions adjacent to the vertebral endplate seen on MRI, have been associated with back pain. There are different types of MCs, with different histopathological correlates. This community-based study sample comprised 110 men from the Twin Spine Study, with baseline, 5-year, and 15-year follow-up MRIs. Following training and reliability testing, 1320 endplates (T12-S1) were evaluated for MC presence, type, and dimensions at each time point. Results demonstrated that Type 2 Modic Changes (MC2) were the most common type, with approximately half located at the two lowest disc levels. However, Type 1 Modic Changes (MC1) …

Functional Performance Testing In Ice Hockey: The Role Of The Single Leg, Medial Countermovement Jump, Anthony S. Donskov

Electronic Thesis and Dissertation Repository

Due to the physical nature of the game, injuries are common in ice hockey. Injury rates have been difficult to interpret due to the inconsistencies in the definitions of injury and athlete exposure. Consensus statements on injury definitions have been developed for sports such as soccer and rugby but have not been established in ice hockey. Furthermore, many different off-ice tests are performed, but a hockey-specific performance test has not been promoted. Accordingly, the objective for this thesis was to investigate injury rates, injury definition, athlete exposure and injury type in men’s ice hockey, and providing information on a practical …

Development And Initial Validation Of Novel Multi-Planar Neck Strength Assessment And Neuromuscular Training Protocols, Theo H. Versteegh

Electronic Thesis and Dissertation Repository

Concussions are a serious health concern in today’s active society. There are many contributing factors to concussions but one that is starting to draw significant attention is the potential role the neck muscles play in mitigating concussive forces. There is evidence that stronger neck muscles may decrease an individual’s concussion risk. In order to fully define this role, an appropriate outcome measure for assessing neck strength is required. Once this is established, methods of training to improve neck strength can be evaluated for their effect on neck strength and subsequently effect on concussion risk. This thesis included three studies. Chapter …

Psychometric Evaluation Of Self-Report Pain And Disability Measures For Elbow Disorders, Joshua Vincent

Electronic Thesis and Dissertation Repository

Elbow disorders are one of the commonest musculoskeletal problems with a prevalence of 9% in men and 8.1% in women. Patient centered care is the goal of current healthcare delivery models; but optimizing treatment outcome and clinical research is hampered by a lack of outcome measures. Since pain and disability resulting from elbow disorders are experienced differently across individuals, they are best captured by patient reported outcome measures (PROM).

PROMs like the Patient-rated Elbow Evaluation (PREE); American Shoulder and Elbow surgeons – Elbow form (pASES-e) have been developed for use in elbow disorders, but important questions remain about their measurement …
