The Effect Of Fatigue On Lower Extremity Joint Kinematics And Performance, Shelley Payne, Sarah Alloto, Joe Wilkins, Ashley Simons

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE

ACL injuries are multifactorial in nature meaning they can be the result of faulty biomechanics, individual genetic predisposition, or environmental factors (Alentorn- Geli et al., 2009). A focus of most healthcare professionals including physical therapists and athletic trainers includes the screening for preventable risk factors for non- contact ACL injuries. Preventable risk factors include asymmetry between a person’s limbs, decreased hamstring strength, increased muscle fatigue, decreased landing angle of hip and knee Tlexion, increased valgus landing, and lack of Tlexibility in the hip internal rotators (Brophy, 2021). Given the short and long-term negative consequences of an ACL injury, it …

Effects Of Pubertal Growth Variation On Knee Mechanics During Walking In Female And Male Adolescents, Andrew W. Froehle, Brian A. Edwards, Matthew Peterson, Brian Meyerson, Dana Duren

School of Health and Exercise Sciences Faculty Publications

Introduction: Puberty substantially alters the body's mechanical properties, neuromuscular control, and sex differences therein, likely contributing to increased, sex-biased knee injury risk during adolescence. Female adolescents have higher risk for knee injuries than male adolescents of similar age engaging in similar physical activities, and much research has investigated sex differences in mechanical risk factors. However, few studies address the considerable variation in pubertal growth (timing, pace), knee mechanics, and injury susceptibility within sexes, or the impact of such growth variation on mechanical injury risk.

Objectives: The present study tested for effects of variation in pubertal growth on established mechanical …

Obstacle Crossing In Healthy Young And Older Individuals, Hope M. Hanson, Ashlyn M. Jendro, Abigail C. Schmitt

Health, Human Performance and Recreation Undergraduate Honors Theses

Introduction: In the United States, the average population age is rising and will continue to increase in the coming years.With an older population comes increased risk of injury associated with falls. Falls are considered a leading cause of injury and death in older individuals, and many falls are caused by body imbalance or obstacle collision due to a clearly visible stationary object (e.g., rug, chair, branch). Older adults tend to cross obstacles with increased toe clearance in order to prevent tripping, but much of what is known about obstacle crossing in older adults is limited to artificial obstacles that are …

The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman

Senior Honors Theses

Osteoarthritis is a prominent and debilitating form of joint disease characterized by pain and deterioration of the articular cartilage and other tissues in the affected joint. Research has identified a variety of risk factors for osteoarthritis, including age, obesity, gender, previous injury, and occupation. The relationship between running and osteoarthritis is a topic of particular interest because of the prevalence of running as a simple and physiologically beneficial form of exercise. Increasing evidence suggests that recreational running has at worst no effect and at best a protective effect on joint and articular cartilage health in contrast to high-intensity professional/elite-level running …

Accelerometry-Based Analysis Of Postural Sway In Parkinson's Disease Patients With Levodopa-Induced Dyskinesia, Chandler Brock

UNO Student Research and Creative Activity Fair

Parkinson’s disease (PD) is a progressive neurodegenerative disorder, with patient numbers projected to double to 12 million in the next 20 years. Levodopa-induced dyskinesia (LID) is a major problem associated with the long-term use of levodopa for symptomatic treatment of PD. These involuntary movements can become disabling and may interfere with quality of life. Our prior research showed that PD w/ LID were less stable while standing (i.e., increased postural sway) and had a higher incidence of falls. The aim of this study is to determine if postural sway properties are altered by LID via decomposing the sway signal. We …

Biomechanically-Consistent Skin Stretch As An Intuitive Mechanism For Sensory Feedback: A Preliminary Investigation In The Lower Limb, Jenny A. Kent

Physical Therapy Faculty Research

The proprioceptive loss accompanied by lower limb amputation can impair function and mobility. We explore a simple, mechanical skin-stretch array configured to generate superficial tissue behaviour that might occur with movement about an intact joint. Four adhesive pads attached around the circumference of the lower leg were connected via cords to a remote “foot” mounted on a ball joint attached to the underside of a fracture boot, such that “foot” reorientation would result in skin stretch. In two discrimination experiments performed with and without the connection, with no view of the mechanism, and with minimal training, unimpaired adults (i) estimated …

A Comparison Of Peak Ground Reaction Forces Of Pitches From The Stretch And Windup, Richard D. Edwards

Graduate Theses/Dissertations

Ground reaction forces can help coaches and players understand the lower extremity biomechanics of pitching in baseball. Research has told us that there are repeatable characteristics of ground reaction forces that pitchers produce during a pitch. This study examines the differences in peak ground reaction forces produced from pitching from the stretch versus pitching from the wind-up. Five variables were recorded for each pitch from the push-off leg and the landing leg. Landing forces were then compared to landing forces of the other pitching style and the same comparison was made for the push-off leg. This was achieved by altering …

Meta-Analytic Connectivity Modelling Of Healthy Swallowing, Chris R. Tilton

Honors Theses and Capstones

A quantitative, voxel-wise meta-analysis was performed to investigate the brain regions involved in healthy human swallowing. Studies included in the meta-analysis (1) examined water swallowing, saliva swallowing, or both, (2) included healthy, normal subjects, and (3) reported stereotaxic brain activation coordinates in standard space. Following these criteria, a systematic literature review identified 8 studies that met the criteria. An activation likelihood estimation (ALE) meta-analysis and meta-analytic connectivity modelling (MACM) analysis were performed with BrainMap software.

Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell

Williams Honors College, Honors Research Projects

Damp granular media is a difficult environment to study because it is both practically complex and it lacks equations which fully describe its behavior. In this study, an oscillatory lateral head movement and its effects while penetrating damp granular media were tested using a robophysical model. This experimental research was inspired by the burrowing behavior of the clade Amphisbaenia, a group of usually limbless squamates that employ a variety of different burrowing behaviors, but it can apply to a wide range of burrowers. This research could help with both human burrowing technologies and the further investigation of animal behaviors.

Validation Of An Emg Submaximal Method To Calibrate A Novel Dynamic Emg-Driven Musculoskeletal Model Of The Trunk: Effects On Model Estimates, Amir H. Eskandari, Farshid Ghezelbash, Aboulfazl Shirazi-Adl, Denis Gagnon, Hakim Mecheri, Christian Larivière

Études primaires

Background

Multijoint EMG-assisted optimization models are reliable tools to predict muscle forces as they account for inter- and intra-individual variations in activation. However, the conventional method of normalizing EMG signals using maximum voluntary contractions (MVCs) is problematic and introduces major limitations. The sub-maximal voluntary contraction (SVC) approaches have been proposed as a remedy, but their performance against the MVC approach needs further validation particularly during dynamic tasks.

Methods

To compare model outcomes between MVC and SVC approaches, nineteen healthy subjects performed a dynamic lifting task with two loading conditions.

Results

Results demonstrated that these two approaches produced highly correlated results …

Investigation Of Lower Extremity Neuromuscular Function In Individuals With And Without Diabetes, Roya Hoveizavi

Theses and Dissertations--Kinesiology and Health Promotion

Background: Diabetes mellitus is associated with notable neuromuscular and motor dysfunctions that could lead to an increased risk of plantar ulcers and amputations. Several contributing factors, including increased muscle-tendon stiffness and abnormal muscle activation pattern may influence the kinematics and kinetics of walking in people with diabetes and promote formation of plantar ulcers. Hyperglycemia and the resultant accelerated rate of glycation have been recognized as the leading cause of muscle and tendon degeneration, yet the precise mechanisms by which diabetes affects the biomechanical properties of the muscle-tendon unit remains unclear. Altered muscle activity during gait is observed in people with …

Reliability And Validity Of A Commercial Running Power Meter To Indicate Metabolic Workload During Endurance Running, James Harris Hudgins Iii

Theses and Dissertations--Kinesiology and Health Promotion

Commercial running power (RP) meters may provide endurance runners and coaches with improved precision for monitoring running intensity. Cyclists rely upon the relationship between cycling power and metabolic demand to regulate physiological intensity during training and racing, independent of changes in the physical environment (e.g., terrain, wind). Research demonstrates strong reliability and validity for a specific RP meter to indicate metabolic demand within controlled running conditions. However, several potential influences on this relationship have not been investigated. Therefore, four studies were conducted with the following aims:

- Study 1: Determine the inter-limb reliability and validity of a single-limb-based RP meter …

The Immediate Effects Of The Nunee Patellar Support On Individuals With Patellofemoral Pain Syndrome, Nick Linn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Patellofemoral pain syndrome (PFPS) is a common form of anterior knee pain caused by general overuse, muscular weakness or strength imbalances, and poor movement coordination leading to abnormal alignment or mal-tracking of the patella. Recent guidelines do not recommend the use of a knee orthosis due to a lack of evidence supporting their effectiveness. A new patellar support (NuNee, K-Neesio LLC.) which uses distraction force to relieve pressure placed on the patella, has been proposed. The purpose of this study was to examine the immediate effects of the NuNee patellar support on perceived pain, biomechanics, and function in individuals with …
