Waiting On The World (Of Allied Healthcare) To Change: How Undergraduate Preparedness Curriculum Dis/Includes Ability, Brianna Donnelly

West Chester University Doctoral Projects

Significant concerns for healthcare practitioners and allied health professionals continue to arise regarding treatment of persons with disabilities. Whether disability exists as apparent or non-apparent, temporary, or chronic, people with disabilities tend to be in poorer health and tend to use health care at a significantly higher rate than people who do not have disabilities. Importantly, the absence of professional training on disability competency issues for health care practitioners is one of the most significant barriers that prevent people with disabilities from receiving appropriate and effective health care. This qualitative narrative analysis explores the inclusion of disability concepts and people …

Hamstring And Quadriceps Activation During Single Leg Hopping At Varying Frequencies: Electromyography Analysis, Jemma Bosselman

Scripps Senior Theses

Identification of knee motor control strategy is salient both for biomechanical understanding of the lower limb and for medical applications. Integral to knee function are the quadriceps and hamstring, an antagonistic muscle pair. Sub-optimal relative activation of the pair can increase injury potential. Muscle activation patterns are largely activity specific, necessitating muscle control research across various tasks. Single leg hopping has been sparsely studied, particularly for muscle activation in relation to hopping frequency. This project thus aimed to determine the effect of single leg hopping frequency on quadriceps and hamstring activation using surface electromyography (EMG), with the vastus lateralis (VL) …

Effects Of Unilateral Lower Limb Suspension On Quadriceps’ Structure And Contractile Function, Eve N. Elmore Jan 2024

Effects Of Unilateral Lower Limb Suspension On Quadriceps’ Structure And Contractile Function, Eve N. Elmore

Theses and Dissertations--Kinesiology and Health Promotion

BACKGROUND: Muscle unloading such as bed rest or space flight decreases strength and cross-sectional area concomitant with a slow-to-fast fiber type shift, of anti-gravitational muscles such as the quadriceps. Diffusion tensor imaging (DTI) quantifies tissue anisotropic properties such as Fractional Anisotropy, Mean Diffusivity, Axial Diffusivity, and Radial Diffusivity, as well as muscle volume, fascicle length, and physiological cross-sectional area, and has recently been adapted to assess skeletal muscle structure. In skeletal muscle, anisotropic properties correlate with muscle fiber type and contractile function and may be responsive to unloading-induced atrophy.

PURPOSE: To assess the changes in quadriceps’ size, anisotropy, and contractile …

Mimicking An Asymmetrically Walking Visual Cue Alters Gait Symmetry In Healthy Adults, Krista G. Clark, Louisa D. Raisbeck, Scott E. Ross, Christopher K. Rhea Jan 2024

Mimicking An Asymmetrically Walking Visual Cue Alters Gait Symmetry In Healthy Adults, Krista G. Clark, Louisa D. Raisbeck, Scott E. Ross, Christopher K. Rhea

Rehabilitation Sciences Faculty Publications

Gait asymmetries are a common problem in clinical populations, such as those with a history of stroke or Parkinson’s disease. The use of a split-belt treadmill is one way to enhance gait symmetry but relies on specialty (and typically expensive) equipment. Alternatively, visual cues have been shown as a method to alter gait mechanics, but their utility in altering gait symmetry has been relatively understudied. Before deploying this method to clinical populations, a proof-of-concept study is needed to explore using visual cues to alter gait symmetry in healthy adults. Therefore, the purpose of this study was to examine the extent …
