Clinical And Radiographic Assessment Of Lumbar Spine Total Disc Replacement In Athletes With Two Year Follow Up, Mark H. Mcrae

Yale Medicine Thesis Digital Library

The purpose of the study was to evaluate the consequences of athletic activity on the clinical and radiographic outcomes of lumbar spine total disc replacement (TDR) patients. The data for this study is drawn secondarily from a prospective randomized study evaluating the Prodisc prosthesis at Yale New Haven Hospital. Athletic activities prior to the onset of spinal injury, after the onset of spinal injury, and post lumbar spine total disc replacement (TDR) surgery were assessed. Athletic activity was classified into three groups. These were contact/vigorous, moderate, and light, based on effect on the involved spinal segments. Outcomes were assessed both …

Barriers And Facilitators To A Healthy Diet And Physical Activity, Tiffany Black, Jennifer Buelt, Aubrey Trefz, Brian Tuchscherer

Physical Therapy Scholarly Projects

Background and Purpose: The purpose of this study was to assess the barriers and facilitators to a healthy diet and physical activity of students attending the University of North Dakota. The research was designed to determine the students overall perception of the specific barriers and facilitators, however researchers also wanted to specify disparities existing among the different ages, genders, physical activity levels, body mass index and ethnicity. This study determined the attitudes and beliefs of UND students towards a healthy lifestyle. From the information gathered the researchers were able to make recommendations for program implementation and improvement.

Methods: A sample …

The Effect Of Hand Position On Maximum Performance Of Push-Ups In Adults, Gregory Douglas Brickey

Open Access Theses & Dissertations

Push-ups are widely used in public school physical education classes, and by military and law enforcement organizations to test upper body muscular fitness. The majority of the test protocols do not specify a hand position. Some research has demonstrated that hand positioning has a significant effect of on electromyographic activity of the working muscles, ground reaction forces and elbow joint loads during single or sub-maximal push-ups. However there are no scientific studies on how a change of hand positions would affect performance in a maximal push-up test to volitional exhaustion. This study examined performance in a maximal push-up test in …

Thermal Sensitivity Of Vagal Pulmonary Sensory Neurons: Role Of Transient Receptor Potential Vanilloid Channels, Dan Ni

University of Kentucky Doctoral Dissertations

Hyperthermia can occur in lungs and airways during both physiological and pathophysiological conditions. A previous study carried out in our laboratory showed that hyperthermia activates and sensitizes vagal bronchopulmonary Cfiber afferents, whether this effect is through a direct action of hyperthermia on sensory nerves is not known. This dissertation study was aimed to investigate the thermal-sensitivity of pulmonary sensory neurons, and the roles of thermalsensitive transient receptor potential vanilloid (TRPV) channels. Whole-cell patch-clamp recordings of neurons isolated from nodose/jugular ganglia were applied in the study. Results of this study showed that hyperthermia directly activates pulmonary sensory neurons, and this effect …
