Neuromuscular Adaptations Following Slope Walking In Individuals Post-Stroke, Eric Akoopie, Brooke Conway Kleven, Trisha Koch

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: The excitability of the H-reflex pathway in the non-impaired nervous system can be augmented by altering the different parameters of a walking task, specifically slope. We sought to examine the adaptations in soleus H-reflex excitability and foot force control following an acute bout of upslope or downslope treadmill walking in people post-stroke compared to those who are non- impaired. Methods: We recruited 12 individuals with chronic post-stroke hemiparesis and 9 age-similar non- neurologically impaired individuals. Each subject was tested over 2 sessions separated by at least 7 days. For each session, subjects walked at a self-selected walking speed on …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Subjects: Twenty recreational runners participated (mean age of 24.9 years). Methods: Kinematics and kinetics of the trunk and lower extremity were obtained at 3 conditions: level, 6° uphill, and 6° downhill, at a speed of 2.3 m/s. PFJ stress was determined using a biomechanical model that incorporates knee flexion angle and knee extensor moment as subject-specific input variables. The model output consisted of PFJ reaction force, PFJ stress, and PFJ contact area. One-way ANOVAs with repeated measures and post-hoc t-tests with a Bonferroni adjustment were used to compare outcome variables across the 3 conditions. Results: Peak PFJ stress during downhill …


The Moderation Effect Of Bdnf Genotype And Self-Reported Habitual Physical Activity Levels On Age Of Onset, Disease Progression, And Postural Instability In Parkinson's, Kyle Johnson, Danielle Salgo, Jessica Zorn May 2018

The Moderation Effect Of Bdnf Genotype And Self-Reported Habitual Physical Activity Levels On Age Of Onset, Disease Progression, And Postural Instability In Parkinson's, Kyle Johnson, Danielle Salgo, Jessica Zorn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Brain-derived neurotrophic factor (BDNF) levels have been reported to play an important role in driving neuroprotection in people with neurologic disorders, and levels of BDNF are known to increase in response to physical activity. Moreover, the level of BDNF produced is also affected by BDNF genotype. It is not known, however, whether one’s BDNF genotype interacts with physical activity throughout life to affect a neuroprotective response in people with Parkinson’s disease (PD). Therefore, the purpose of this study was to determine if BDNF genotype interacts with lifetime self-reported physical activity levels to affect disease severity and progression …


The Influence Of Socioeconomic Factors On Fear Of Falling And Mobility Outcomes After Lower Limb Loss: A Preliminary Study, Tyler Chin, Heather Fox, Juan Gutierrez Jr. May 2018

The Influence Of Socioeconomic Factors On Fear Of Falling And Mobility Outcomes After Lower Limb Loss: A Preliminary Study, Tyler Chin, Heather Fox, Juan Gutierrez Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Current research has revealed that as much as 52.4% of individuals with lower limb loss report falling at least once in the past year. Previous research has also indicated that rehabilitation, including physical therapy (PT), generally improves patient outcomes after definitive amputation. Socioeconomic status has been shown to be an important factor in accessing healthcare but has yet to be investigated in this population. The purpose of this study was to investigate the effects of socioeconomic status and access to PT, and how limb loss affects mobility and fear of falling perception. We hypothesized: [1] individuals with …


Successful Patient Participation In Acute Hospital Physical Therapy, Jesse Kim, Joseph Fertitta, Patrick Williams May 2018

Successful Patient Participation In Acute Hospital Physical Therapy, Jesse Kim, Joseph Fertitta, Patrick Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Research has demonstrated that physical therapy plays a crucial role in patient recovery in the acute hospital setting. Despite known benefits, scheduled sessions do not always occur and are called nontreatment (NT) events. Reported NT ranges from 15% to 26% of scheduled sessions. Previous studies have found an association between NT and patient diagnosis as well as between NT and day of the week on which treatment was scheduled. Identifying additional factors that affect NT is important if therapists and administrators are to make improvements. The purpose of this study is to determine if an association exists between physical …

Investigation Of The Cardiovascular Endurance Of Dance Majors, Arnold Huang, Ali Ross, Kelsey Taelour, Geneva Winters

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: College dancers have demonstrated low levels of cardiovascular endurance compared to other athletes, which could be one of the factors that leads to more fatigue and injuries during performance. The effects of an education session on cardiovascular endurance and on college dancers’ attitudes towards cardiovascular exercise outside of dance class have not been previously studied. Purpose: The purpose of this study was to use the accelerated three-minute step test to compare lower level and upper level college dancers’ cardiovascular endurance before and 2 months after an education session emphasizing fitness and exercise. Additionally, assessed were the dancers’ attitudes towards …

UNLV Theses, Dissertations, Professional Papers, and Capstones

STUDY DESIGN: Case control study. BACKGROUND: Recurrent low back pain (RLBP) is associated with paraspinal muscle dysfunction. Intramuscular electromyography (EMG) is a common tool for studying activation of the deep lumbar paraspinal muscles such as multifidi muscles, but it is currently currently unclear how muscle performance and activation are affected by the pain and micro-injury associated with intramuscular fine-wire electrode (IFWE) insertion and how it interacts with the presence of RLBP. OBJECTIVES: The purpose of this study was to examine how IFWE insertion into the lumbar multifidus affects paraspinal muscle strength and endurance in subjects with and without RLBP. METHODS: …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Pressure injuries (PI) are prevalent and costly for hospitals. Hospitals implement different practices to accurately document PIs ranging from pen and paper to photodocumentation in electronic medical records (EMRs). In some instances, PIs that have been documented are not coded for billing and reporting. The purpose of this study is to determine if different documentation practices affect the number of coded PIs. Methods: Counts of coded PIs were collected from 2011- 2017 from two hospitals: a 500-bed acute care hospital (ACH) and a 42-bed acute rehabilitation hospital (ARH). A series of PI documentation practices were implemented over …
