The Contribution Of Small And Large Sensory Afferents To Postural Control In Patients With Peripheral Neuropathy, Li Li, Shuqi Zhang, John Dobson

Health Sciences & Kinesiology: Faculty Publications

Peripheral neuropathy (PN) is a multifarious disorder that is caused by damage to the peripheral nerves. Although the symptoms of PN vary with the etiology, most cases are characterized by impaired tactile and proprioceptive sensation that progresses in a distal to proximal manner. Balance also tends to deteriorate as the disorder becomes more severe, and those afflicted are substantially more likely to fall while walking compared with those who are healthy. Most patients with PN walk more cautiously and with greater stride variability than age-matched controls, but the majority of their falls occur when they must react to a perturbation …

The Mediation Of Perfectionism And Rumination On Mindfulness And Burnout In Collegiate Athletes, Nicholas S. Mcmillen

College of Graduate Studies: Theses & Dissertations

Several positive and negative sport-related experiences can occur throughout an athlete’s career, which can affect the continuation or termination of said career. Although research has associated sport participation with positive outcomes (e.g., increases in motivation, autonomy), there are also negative sport-related outcomes such as burnout (Akhrem & Gazdowska, 2016; Garcia, 2015). Specifically, burnout has been identified as a multidimensional construct that includes three dimensions. Furthermore, mindfulness has been studied to minimize the risk of experiencing burnout (Kabat-Zinn, 2003). While several studies have examined mediators between mindfulness and burnout, there has been a dearth of research on perfectionism and rumination as …

Parallel And Cross-Sectional Hamstring Injuries In Sprint Running, Li Li, Donghai Wang

Health Sciences & Kinesiology: Faculty Publications

This issue of Journal of Sport and Health Science contains a point-counterpoint discussion of hamstring injuries in sprint running by the groups of Drs. Liu and Yu.^1–4 They propose different mechanisms of muscle injuries in general, and hamstring injuries in sprint running specifically. Yu et al.^2,4 present evidence suggesting that hamstring injuries are primarily caused by excessive muscle strain during eccentric contraction. In maximal effort sprint running, excessive muscle strains occur at the end of the swing phase. In contrast, Liu et al.^1,3 point out that, in addition to excessive hamstring strain, high stresses in the late …

Assessment Of Anti-Saccades Within 24 To 48 Hours Post-Concussion, Nathan D'Amico

GS4 Student Scholars Symposium

INTRODUCTION: Approximately 90% of concussions involve oculomotor impairment, with saccadic eye movement deficits being the most prominent oculomotor impairment. Saccades are rapid eye movements that bring a fixed point or area of interest into the center of sight and are important for safely navigating through the environment. Anti-saccades are saccadic eye movement deficits that involve a reflexive, involuntary saccade away from a fixed point or area of interest. Assessments of anti-saccades may provide a fast, accurate, and reliable way to screen for concussion. However, little research quantitatively explores anti-saccades post-concussion.

PURPOSE: To investigate anti-saccades between NCAA Division I athletes 24-48 …
