Mechanisms To Increase Propulsive Force For Individuals Poststroke, Haoyuan Hsiao, Brian A. Knarr, Jill S. Higginson, Stuart A. Binder-Macleod

Journal Articles

Background: Propulsive force generation is critical to walking speed. Trialing limb angle and ankle moment are major contributors to increases in propulsive force during gait. For able-bodied individuals, trailing limb angle contributes twice as much as ankle moment to increases in propulsive force during speed modulation. The aim of this study was to quantify the relative contribution of ankle moment and trailing limb angle to increases in propulsive force for individuals poststroke.

Methods: A biomechanical-based model previously developed for able-bodied individuals was evaluated and enhanced for individuals poststroke. Gait analysis was performed as subjects (N = 24) with …

Exercise In Individuals With Down Syndrome: A Brief Review, Rachel L. Kerstiens, Matt Green

International Journal of Exercise Science

International Journal of Exercise Science 8(2): 192-201, 2015. Research examining acute and long-term responses to exercise of individuals with Downs Syndrome (DS) is sparse. However, if this group experiences benefits associated with improved quantity or quality of life, it would be important to elucidate specific responses and discourage adoption of a sedentary lifestyle in individuals with DS. Specifically, these individuals have multiple blunted physiological responses to exercise both at the onset and termination of an acute exercise bout. Mechanistically, this could be rooted in hormonal responses which are blunted, in comparison to non-DS participants. Specific studies indicate individuals with …

Biomechanical Analyses Of Stair-Climbing While Dual-Tasking, Srikant Vallabhajosula, Chi Wei Tan, Mukul Mukherjee, Austin Davidson, Nicholas Stergiou

Journal Articles

Stair-climbing while doing a concurrent task like talking or holding an object is a common activity of daily living which poses high risk for falls. While biomechanical analyses of overground walking during dual-tasking have been studied extensively, little is known on the biomechanics of stair-climbing while dual-tasking. We sought to determine the impact of performing a concurrent cognitive or motor task during stair-climbing. We hypothesized that a concurrent cognitive task will have a greater impact on stair climbing performance compared to a concurrent motor task and that this impact will be greater on a higher-level step. Ten healthy young adults …

Individual Analysis Of T2*-Weighted Gradient Echo Imaging In Asymptomatic And Symptomatic Athletes, Xianglun Mao

Open Access Theses

Mild traumatic brain injury (mTBI), is a commonly occurred sports-related injury, especially in contact sports like football and soccer. Hemorrhage will appear as hypointense lesions on T₂ ^*-weighted images, resulting from mTBI. Thus, T ₂^*-weighted gradient echo pulse sequence can be used to generate magnitude susceptibility-weighted (SW) images, and to further detect negative intensity changes of different regions of interests (ROIs) inside human brains. Our goal was to investigate how the ROI-specific intensity changes in each individual sports athlete over a single competition season and to interrogate whether these changes are correlated with repetitive subconcussive or …

Cerebrovascular Reactivity Alterations Due To Subconcussive Repetitive Head Trauma In Asymptomatic High School Football Players, Chetas Joshi

Open Access Theses

Chronic neurological damage as a result of chronic repetitive head trauma is a major concern for football athletes today. Repetitive concussions have been linked to many neurological disorders. Recently, it has been reported that repetitive subconcussive events can contribute to long-term neurodegeneration. For these reasons, it is important to understand the effect repetitive subconcussive head trauma has on brain health in young athletes. Past research has demonstrated that cerebrovascular reactivity (CVR), an important mediator of cerebrovascular regulation, is impaired following mild traumatic brain injury (mTBI). This impairment increases susceptibility to secondary injury following mTBI. In this study, Breath-Hold (BH) task …

Contra-Compartmental Joint Mechanics In Unicondylar Knee Arthroplasty, Roy Rusly

All Dissertations

Recently, unicondylar knee arthroplasty (UKA) has seen a resurgence in clinical popularity, due to its increased success rate, improvement in implant designs, and more efficient surgical techniques. However, it continues to be a more technically demanding procedure and less forgiving compared to TKA [14,16-19]. The early reported failures due to the malalignment errors during surgery remain areas of concern clinically and experimentally [41-44,46]. In addition, the difference in the compliance between the UKA implant materials (metal-polymer) and the soft tissues in the un-operated comparted could also affect the load distribution on the knee joint. Advancement in medical technology and improvement …

Division Of Labor In Hand Usage Is Associated With Higher Hand Performance In Free-Ranging Bonnet Macaques, Macaca Radiata, Madhur Mangalam, Nisarg Desai, Mewa Singh

Journal Articles

A practical approach to understanding lateral asymmetries in body, brain, and cognition would be to examine the performance advantages/disadvantages associated with the corresponding functions and behavior. In the present study, we examined whether the division of labor in hand usage, marked by the preferential usage of the two hands across manual operations requiring maneuvering in three-dimensional space (e.g., reaching for food, grooming, and hitting an opponent) and those requiring physical strength (e.g., climbing), is associated with higher hand performance in free-ranging bonnet macaques, Macaca radiata. We determined the extent to which the macaques exhibit laterality in hand usage in …

H-Index Is Important For Postural Control For People With Impaired Foot Sole Sensation, Shuqi Zhang, Brad Manor, Li Li

Health Sciences & Kinesiology: Faculty Publications

Introduction: People with Peripheral Neuropathy (PN), especially those with impaired sensory inputs through the small-afferent fiber (type II afferent fibers) reflex loop (SAF), might depend more on the large-afferent fiber (type I afferent fibers) reflex loop (LAF) for postural control.

Purpose: To examine whether the function of the LAF reflex loop, reflected by the H-reflex and ankle joint proprioception, influences postural control when the SAF reflex loop is impaired, as indicated by reduced foot sole cutaneous sensation.

Methods: Thirteen participants (8 women, 5 men) diagnosed with PN and 12 age-matched controls (7 women, 5 men) completed the testing protocol. Measures …

Children’S Looking Preference For Biological Motion May Be Related To An Affinity For Mathematical Chaos, Joshua L. Haworth, Anastasia Kyvelidou, Wayne Fisher, Nikolaos Stergiou

Journal Articles

Recognition of biological motion is pervasive in early child development. Further, viewing the movement behavior of others is a primary component of a child’s acquisition of complex, robust movement repertoires, through imitation and real-time coordinated action. We theorize that inherent to biological movements are particular qualities of mathematical chaos and complexity. We further posit that this character affords the rich and complex inter-dynamics throughout early motor development. Specifically, we explored whether children’s preference for biological motion may be related to an affinity for mathematical chaos. Cross recurrence quantification analysis (cRQA) was used to investigate the coordination of gaze and posture …
