Joint Loading Factors Of Articular Cartilage Structure In Healthy And Acl-Injured Knees, Elizabeth Wellsandt

Theses & Dissertations

Articular cartilage structure and chondrocyte health are sensitive and reliant on dynamic joint loading during activities. The risk of osteoarthritis (OA) is high after anterior cruciate ligament (ACL) injury, but mechanisms underlying its development are poorly understood. The overall goals of this work were 1) to determine the association between measures of individual and cumulative knee joint loading with T2 relaxation times in the knee cartilage of young individuals without injury and 2) to determine if these same knee joint loading factors are associated with cartilage T2 relaxation time one month after ACL injury. The central hypotheses was that lower …

Effects Of Liquid Viscosity And Food Texture On Swallowing Sounds, Chun Feng

Theses & Dissertations

Cervical auscultation (CA) is a technique of monitoring swallowing performance according to swallowing acoustic signals utilizing a stethoscope or other measurement devices such as a microphone and an accelerometer. In the past few years, doctors have utilized the stethoscope to identify the swallowing sounds, which resulted in an inability to accurately diagnose the aspiration/penetration in patients with dysphagia when compared to the gold standard. A digital CA assessment records swallowing acoustic signals and extracts the specific features from the recordings. It has been proven that digital CA as a promising portable and low-cost tool can be used for identifying patients …

Declined Treadmill Walking Eliminates Asymmetric Walking Pattern In Healthy Young Adults, Yuhang Zhang, Ka-Chun Siu, Jung Hung Chien

Posters and Presentations: Physical Therapy

Background: Human locomotion is flexible in any environment, and this fact has been proven when walking on different speeds in each leg on the split-belt treadmill. However, during the split-belt walking, participant’s locomotor behaviors are passively adopted by a motor-driven treadmill. Therefore, how humans actively adjust the flexibility of locomotion is still limited by using the split-belt treadmill. Our current study investigated the flexibility of locomotion by using ankle weight on the dominant leg to induce asymmetric walking pattern when walking on a regular treadmill. We hypothesized that the level of active control would increase to adapt the asymmetric walking …

The Use Of Immersive 360 Videos To Induce Different Strategies Of Postural Control, Chenfan Gui, Jung Hung Chien, Ka-Chun Siu

Posters and Presentations: Physical Therapy

Purpose/Hypothesis: Visual perception is a decision-making process of the central nervous system based on recognitions of relative distances and velocities between objects. With the input from visual perception, an appropriate postural control is applied to maintain balance. Previous studies on how visual perception affects the postural control were only in one direction. Therefore, this study used immersive 360° videos to identify how visual perception affects the postural control in multiple directions. We hypothesized that video with more turns could induce more ML body sway, and video with higher elevation could induce more AP body sway. Number of Subjects: Nineteen healthy …

The Effect Of Inclination On Lower Extremity Inter-Joint Coordination During Treadmill Walking, Jiani Lu, Jung Hung Chien, Ka-Chun Siu

Posters and Presentations: Physical Therapy

Purpose/Hypothesis: Inclined walking is a challenging daily task in comparison with level walking. It requires specific control from central nervous system and exhibits increases in muscle activities and alternations of joint kinematics in lower extremities. However, the knowledge of the inclination effect on the inter-joint coordination is limited. Previous studies have shown the benefits of investigating the inter-joint coordination in patients with Parkinson’s disease, low back pain and hemiplegic gait. This study aimed to evaluate such coordination in healthy young adults during inclined walking.

Number of Subjects: 19 healthy young adults (13 females, 6 males; aged 22 – 29 yrs) …

Designing A Course To Acculturate Professional Behaviors Of International Students In Physical Therapy Education, Nicole M. Sleddens, Kathleen G. Volkman, Betsy J. Becker, Ka-Chun Siu, Michael Smith, Joseph F. Norman

Posters and Presentations: Physical Therapy

The University of Nebraska Medical Center DPT program has a Global Health Opportunity track in which international students work on a master’s degree and complete a DPT. The current students are from China and meet all requirements of the DPT and graduate admissions, including a high proficiency in English (e.g. TOEFL ³ 90). All students have undergraduate degrees in medicine, rehabilitation therapy or medical sciences from universities in China. While these students have performed well in the didactic DPT curriculum, we noted a trend in professional interactions and communication which interfered with clinical performance and required remediation. To proactively circumvent …

Reaching The Summit: From Exposure To Immersion In Quality Improvement In Physical Therapy Education, Tami Struessel, Nicole M. Sleddens, Katherine J. Jones

Posters and Presentations: Physical Therapy

Following the release of its 2001 report, Crossing the Quality Chasm: A New Health System for the 21st Century, the Institute of Medicine (IOM) convened a summit of 150 interprofessional healthcare educators to reform health professions education. As a result, in 2002, the IOM established an overarching vision to achieve care that is safe, effective, patient-centered, timely efficient, and equitable: “All health professionals should be educated to deliver patient-centered care as members of an interdisciplinary team, emphasizing evidence-based practice, quality improvement approaches, and informatics.” Physical Therapy educators have expanded curricula to teach three of these five competencies. We routinely …

Mobile Technology Intervention For Weight Loss In Rural Men: Protocol For A Pilot Pragmatic Randomised Controlled Trial, Christine M. Eisenhauer, Fabiana Almeida Brito, Aaron M. Yoder, Kevin A. Kupzyk, Carol H. Pullen, Katherine E. Salinas, Jessica Miller, Patricia A. Hageman

Journal Articles: Physical Therapy

INTRODUCTION: Men who are overweight or obese in the rural Midwestern USA are an unrepresented, at-risk group exhibiting rising rates of cardiovascular disease, poor access to preventive care and poor lifestyle behaviours that contribute to sedentary lifestyle and unhealthy diet. Self-monitoring of eating and activity has demonstrated efficacy for weight loss. Use of mobile technologies for self-monitoring eating and activity may address rural men's access disparities to preventive health resources and support weight loss. Our pilot trial will assess the feasibility and acceptability of two mobile applications for weight loss in rural men to inform a future, full-scale trial.
