Neurophysiological And Psychological Characteristics Of Individuals With History Of Lateral Ankle Sprain, Katherine Bain

Theses and Dissertations--Rehabilitation Sciences

Lateral ankle sprain (LAS) is among the most common lower limb musculoskeletal injuries impacting both the general and sport populations. Even more problematic is that approximately 70% of individuals who sustain an LAS develop residual deficits. Of that subgroup, roughly 40% develop chronic ankle instability (CAI). Chronic ankle instability is a clinical diagnosis defined by the presence of ongoing impairments following the initial LAS which may include perceived instability, pain, mechanical instability, and episodes of giving way during physical activity. Not all who sustain multiple ankle sprains or experience residual deficits fit the clinical diagnosis criteria for CAI; yet may …

Hip And Knee Joint Angle Patterns And Kicking Velocity In Female And Male Professional Soccer Players: A Principal Component Analysis Of Waveforms Approach, Archit Navandar, Kristof Kipp, Enrique Navarro

Exercise Science Faculty Research and Publications

This study used principal component analysis (PCA) of waveforms to extract movement patterns from hip and knee angle time-series data; and determined if the extracted movement patterns were predictors of ball velocity during a soccer kick. Twenty-three female and nineteen male professional soccer players performed maximal effort instep kicks while motion capture and post-impact ball velocities data were recorded. Three-dimensional hip and knee joint angle time-series data were calculated from the beginning of the kicking leg’s backswing phase until the end of the follow-through phase and entered into separate PCAs for females and males.

Maximal Strength In Relation To Force And Velocity Patterns During Countermovement Jumps, Michael H. Haischer, John Krzyszkowski, Stuart Roche, Kristof Kipp

Exercise Science Faculty Research and Publications

Maximal strength is important for the performance of dynamic athletic activities, such as countermovement jumps (CMJ). Although measures of maximal strength appear related to discrete CMJ variables, such as peak ground reaction forces (GRF) and center-of-mass (COM) velocity, knowledge about the association between strength and the time series patterns during CMJ will help characterize changes that can be expected in dynamic movement with changes in maximal strength. Purpose: To investigate the associations between maximal strength and GRF and COM velocity patterns during CMJ. Methods: Nineteen female college lacrosse players performed 3 maximal-effort CMJs and isometric midthigh pull. GRF …

Developing A Footswitch Device To Assess The Likelihood Of Falls In At-Risk Populations, Arash Mohammadzadeh Gonabadi

UNO Student Research and Creative Activity Fair

Falls are one of the major cause of injuries, reduced functioning and even mortality in older adults. Most of the falls occur during walking, so considering the mechanics of gait during walking can provide insight to identify the risk of fall in this population. A component of walking mechanics associated with falling in the elderly is gait variability (i.e. the inherent natural fluctuations between strides). Healthy states are associated with an optimal level of movement variability reflecting the adaptability of the underlying control system, while pathological gait can be either too regular, or periodic, or too random and disordered. In …

Long-Term High Salt Intake Involves Reduced Sk Currents And Increased Excitability Of Pvn Neurons With Projections To The Rostral Ventrolateral Medulla In Rats, Andrew D. Chapp, Renjun Wang, Zixi Cheng, Zhiying Shan, Qing-Hui Chen

Department of Kinesiology and Integrative Physiology Publications

Evidence indicates that high salt (HS) intake activates presympathetic paraventricular nucleus (PVN) neurons, which contributes to sympathoexcitation of salt-sensitive hypertension. The present study determined whether 5 weeks of HS (2% NaCl) intake alters the small conductance Ca²⁺-activated potassium channel (SK) current in presympathetic PVN neurons and whether this change affects the neuronal excitability. In whole-cell voltage-clamp recordings, HS-treated rats had significantly decreased SK currents compared to rats with normal salt (NS, 0.4% NaCl) intake in PVN neurons. The sensitivity of PVN neuronal excitability in response to current injections was greater in HS group compared to NS controls. The …
