Background/purpose: The Fear of Falling Avoidance Behavior Questionnaire (FFABQ), developed in 2011 to measure fear of falling avoidance behavior, has good evidence for reliability and validity. However, a recently modified version (mFFABQ) is theorized to be easier to understand for those completing the questionnaire because the Likert responses are more logical in completing the item stem. The purpose of this study was to examine the test-retest reliability and construct validity of the mFFABQ in adults with Parkinson’s Disease (PD) and older adults aged 60-90 years. Methods: Thirty-nine participants (age 72.21 ± 9.5; 29 men, 10 women) diagnosed with PD (diagnosis …

Purpose/Hypothesis: Down syndrome (Ds) is a genetic disorder in which the individual carries an extra copy of chromosome 21 resulting in mental and physical disabilities and risk of major health conditions. A high prevalence of gait pattern dysfunction occurs in adults with Ds due to muscle hypotonia, ligamentous laxity, joint hypermobility, and altered development of musculoskeletal structure, which often lead to increased falls and fear of falling. The purpose of this study is to investigate the differences in kinematic and spatiotemporal gait parameters between adults with Ds and age-matched controls, as well as studying the effects of a 12-week Ds-specific …

Background: Postural instability (PI) in Parkinson’s disease (PD) is associated with several negative down- stream consequences. Objective: The purpose was to explore the validity of a theoretical model of these downstream consequences arranged in a vicious cycle wherein PI leads to decreased balance con!dence, which in turn leads to increased fear of falling (FOF) avoidance behavior, which in turn leads to decreased physical conditioning, which then feeds back and negatively affects PI. Methods: A path analysis of cross!sectional data from 55 participants with PD was conducted. The four con- structs in the model connected in succession were: 1. PI (principal …
The Effects Of Somatosensory Input On Gait In Individuals Post-Stroke, Victor Hung, Amanda Reilly, Rachel Wood, Nikita Yuskov
The Effects Of Somatosensory Input On Gait In Individuals Post-Stroke, Victor Hung, Amanda Reilly, Rachel Wood, Nikita Yuskov

Background and Purpose: Stroke is a leading cause of disability that results in various neurological deficits, one of which is hemiplegia. This deficit alters the gait cycle, resulting in decreased propulsion force by plantar flexor muscles, decreased activation of dorsiflexor (DF) muscles, and increased coactivation of antagonistic ankle muscles. Stroke also leads to altered somatosensory input which results in decreased balance and gait speed, ultimately increasing fall risk. Therapies targeting increased somatosensory input have been shown to be beneficial in stroke as well as other neurological populations. However, no known studies have investigated the acute effects of local vibration to …

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 …
Immediate Effects Of Cervical Spine Thrust Joint Manipulation On Gait Parameters In Individuals With Neck Pain, Marc Anthony D. Albano, Emily Blok, Beau Gronert, Ryan Masuda
Immediate Effects Of Cervical Spine Thrust Joint Manipulation On Gait Parameters In Individuals With Neck Pain, Marc Anthony D. Albano, Emily Blok, Beau Gronert, Ryan Masuda
UNLV Theses, Dissertations, Professional Papers, and Capstones
Purpose/Hypotheses: 1. To investigate for any change in gait parameters in individuals with neck pain while walking with different functional neck conditions immediately following cervical thrust joint manipulation (TJM) versus a sham intervention. 2. To investigate any association between Global Rating of Change (GROC) scores and gait parameters immediately following cervical thrust joint manipulation versus a sham intervention. The hypotheses were that, a) cervical TJM would have an immediate effect on gait parameters during walking with the neck in at least one of three conditions (neutral, flexion/extension and rotation) among individuals with neck pain; and b) higher scores on the …
The Effects Of Fatigue On Balance In Individuals With Parkinson's Disease: Influence Of Medication And Brain-Derived Neurotrophic Factor Genotype, Michael Baer, Bradley Klemetson, Diana Scott
The Effects Of Fatigue On Balance In Individuals With Parkinson's Disease: Influence Of Medication And Brain-Derived Neurotrophic Factor Genotype, Michael Baer, Bradley Klemetson, Diana Scott
UNLV Theses, Dissertations, Professional Papers, and Capstones
Background and Purpose: The purpose was to investigate the effects of fatigue on balance in individuals with Parkinson’s disease (PD). Because falls in this population can have deleterious consequences, it is important to understand the influence of fatigue and PD medications on balance. Additionally, since brain-derived neurotrophic factor (BDNF) has been shown to be related to motor performance, we explored its role in balance fatigue. Participants: 27 individuals (age= 65.4±8.1; males= 14, females= 13) with neurologist-diagnosed PD. Of the 27, 13 were genotyped for BDNF as Val/Val, 11 as Val/Met, 2 as Met/Met, and one refused genotyping. Methods: Participants were …

The purpose of this study was to determine if body weight support influences the stride length-speed relationship. Additionally, the purpose was to determine if impact characteristics of running are influenced by body weight support and speed. Subjects (n=10; 6 female, 4 male) volunteered to participate in this study. All subjects were injury free and were comfortable running on a treadmill for 30 minutes. Subjects ran on a lower body positive (LBPP, Alter-G, G-Trainer) treadmill for 4 conditions of body weight (100, 40, 30 and 20% of body weight) and 4 running speeds (100, 110, 120 and 130% of the preferred …
