Children Display Adult-Like Kinetic Pattern In The Time Domain But Not In The Frequency Domain While Walking With Ankle Load, Jianhua Wu, Toyin Ajisafe, Matthew Beerse, Huaqing Liang

Physical Therapy Faculty Research

While external load is added during locomotion, humans increase the activation of extensors during stance and suppress the initiation of flexors during swing. External load at the ankles, rather than on the waist or thigh, elicits higher activities from ankle extensors, and increases stride length and decreases cadence in adults. Spatiotemporal and kinematic patterns become adult-like in children aged 5-8 years. However, little is known if children show adult like kinetic patterns while walking with external load This study aimed to investigate differences in kinetic patterns between children and adults while walking with external ankle load using both time and …

Walking Pattern In Children With And Without Down Syndrome Via A Force-Driven Harmonic Oscillator Model, Jianhua Wu, Matthew Beerse, Toyin Ajisafe, Huaqing Liang

Physical Therapy Faculty Research

Children with Down syndrome (DS) display poorer kinematic and kinetic patterns of walking than typically developing ( TD) children. However, little is known on neuromuscular control in children with DS during locomotion. A force driven harmonic oscillator (FDHO) model sheds light on general muscular activation with respect to the gravitational load of the thigh-shank-foot system. The K/G ratio derived from this model represents a scaling between the elastic restoring torque from muscles and soft tissues and the gravitational torque from the weight of the leg during walking. The K/G ratio has shown different muscular function in infant walkers and children …

Exploring The Effectiveness Of A Prevocational Seminar On Self-Efficacy And Work Motivation Among Inpatient Adults With Severe Mental Illness: An Experimental Study, Amanda L. Foster

Theses and Dissertations - UTB/UTPA

Employment is a primary facet of our social milieu and can be associated with an individual's health and quality of life. Employment has also proven to be an essential element to the recovery of people with severe mental illness (PWSMI); however, PWSMI have the highest unemployment rate out of all groups of individuals with disabilities. Supported employment (SE) is an ideal mainstreaming agent, for PWSMI, into competitive employment; yet, barriers experienced by participants of SE interrupt the overall effectiveness of the program. This study provides insight regarding an intervention designed to assist PWSMI in overcoming employment-related barriers. A pre-test post-test …

Sex Differences In Arm Muscle Fatigability With Cognitive Demand In Older Adults, Hugo M. Pereira, Vincent C. Spears, Bonnie Schlinder-Delap, Tejin Yoon, April L. Harkins, Kristy A. Nielson, Marie K. Hoeger Bement, Sandra K. Hunter

Physical Therapy Faculty Research and Publications

Background

Muscle fatigability can increase when a stressful, cognitively demanding task is imposed during a low-force fatiguing contraction with the arm muscles, especially in women. Whether this occurs among older adults (> 60 years) is currently unknown.

Questions/purposes

We aimed to determine if higher cognitive demands, stratified by sex, increased fatigability in older adults (> 60 years). Secondarily, we assessed if varying cognitive demand resulted in decreased steadiness and was explained by anxiety or cortisol levels.

Methods

Seventeen older women (70 ± 6 years) and 13 older men (71 ± 5 years) performed a sustained, isometric, fatiguing contraction at 20% …

Combined Unilateral Blockade Of Cholinergic, Peptidergic, And Serotonergic Receptors In The Ventral Respiratory Column Does Not Affect Breathing In Awake Or Sleeping Goats, Clarissa Muere, Suzanne Neumueller, Samantha Olesiak, Justin Robert Miller, Thomas Langer, Matthew Hodges, Lawrence Pan, Hubert Forster

Physical Therapy Faculty Research and Publications

Previous work in intact awake and sleeping goats has found that unilateral blockade of excitatory inputs in the ventral respiratory column (VRC) elicits changes in the concentrations of multiple neurochemicals, including serotonin (5-HT), substance P, glycine, and GABA, while increasing or having no effect on breathing. These findings are consistent with the concept of interdependence between neuromodulators, whereby attenuation of one modulator elicits compensatory changes in other modulators to maintain breathing. Because there is a large degree of redundancy and multiplicity of excitatory inputs to the VRC, we herein tested the hypothesis that combined unilateral blockade of muscarinic acetylcholine (mACh), …

Physician Assistant Students' Perceptions Of Mental Illness: A Correlational Study Of Empathy, Attitudes, And Stigma Levels, Juliann M. Garza

Theses and Dissertations - UTB/UTPA

Physician assistant students’ perceptions and attitudes towards mental illness were examined in relation to their empathy levels. The theoretical frameworks of stigma and labeling were explored and examined through the use of surveys and questionnaires to assess prior attitudes and beliefs about individuals with a mental illness. Based on a multiple-regression model and multi-way analysis of variance, this study showed a statistical significance between an individual’s empathy levels and their stigmatization towards mental illness. In addition, the results of this study identified significant relationships between gender and race in terms of empathy. Implications of this study could have far-reaching effects …

Factors Impacting Vocational Rehabilitation Employment Outcomes: An Analysis Of State-Federal Service Provision, Valerie Jeannette Rodriguez

Theses and Dissertations - UTB/UTPA

State-federal vocational rehabilitation (VR) programs are widely recognized for providing various services to individuals with disabilities to help them reach their goals of independence and employment. Because rehabilitation programs are required to meet federal and state goals, standards, and indicators, thorough and ongoing program evaluation is necessary to identify predictors of successful and unsuccessful employment outcomes in order to determine best practices in vocational rehabilitation service delivery.

In the large southwestern state examined in this research study, there is an estimated return on investment of $9 for each dollar spent on successful VR cases. Cases closed successfully by state-federal VR …

Despite an abundance of research and literature documenting the experience of disability in the family the individual with the disability has largely been excluded from this research. This study investigated perceptions of individuals with disabilities regarding the impacts their disabilities have on their family that have been documented in the literature. Specific demographic variables were examined to determine any differences in perceptions based on these variables. Lastly, the underlying concepts of the perceptions of …

Stability Of Isometric Strength Asymmetry And Its Relationship To Sprint And Change-Of-Direction Performance Asymmetry In Division-I Collegiate Athletes, Benjamin H. Gleason

Electronic Theses and Dissertations

The purpose of this dissertation was to evaluate the stability of strength asymmetry over a long-term period (1 year) and investigate the relationship of strength asymmetry to field test performance asymmetry in NCAA division-1 athletes. Isometric mid-thigh pull (IMTP) peak force asymmetry, ground contact time and finish time asymmetries on 10m sprint and 505 agility test performances were also observed. The impact of strength was also investigated in these studies to determine its effect on the magnitude of asymmetry.

In the second study, peak force asymmetry over a one-year period was observed to be a rather volatile quality, with ranges …

Effects Of Pelvis Impact Angle And Hip Muscle Forces On Hip Fracture Risk During A Fall Using An Advanced Hip Impact Simulator, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Over 90% of hip fractures in older adults are caused by falls [1]. Whether a given fall will cause hip fracture depends on bone strength, and on the impact force and stress applied to the bone during impact [2]. Improved understanding is required on how peak bone stresses during a fall depend on the mechanics of a fall, and on the state of contraction at the moment of impact of the muscles spanning the hip. Recently, Choi et al showed that, for lateral impact to the hip, peak stresses decrease with increases in hip abductor muscle force [3]. In the …

Influence Of Pelvis Impact Angle During A Fall: On The Protective Benefit Of Hip Protectors, Woochol J. Choi, Stephen N. Robinovitch

Physical Therapy Faculty Articles and Research

"Over 90% of hip fractures are due to falls [1]. Laboratory measures have shown that wearable hip protectors reduce impact forces to the proximal femur during a simulated sideways fall on the hip [2, 3]. However, clinical evidence suggests that hip fractures still occur when hip protectors are worn [4]. Furthermore, while falls in real life result in a variety of impact configurations, biomechanical tests to date have focused only on lateral impact to the pelvis. In the current study, we examined how the force reduction provided by wearable hip protectors is affected by pelvis impact configuration during simulated sideways …

Improving Outcomes By Implementing A Pressure Ulcer Prevention Program (Pupp): Going Beyond The Basics, Amparo Cano, Debbie Anglade, Hope Stamp, Fortunata Joaquin, Jennifer A. Lopez, Lori Lupe, Steven P. Schmidt, Daniel L. Young

Physical Therapy Faculty Research

A multidisciplinary process improvement program was initiated at the University of Miami Hospital (UMH) in 2009 to identify the prevalence of hospital-acquired pressure ulcers (HAPU) at the institution and to implement interventions to reduce the incidence of HAPU. This deliberate and thoughtful committee-driven process evaluated care, monitored results, and designed evidence-based strategic initiatives to manage and reduce the rate of HAPU. As a result all inpatient beds were replaced with support surfaces, updated care delivery protocols were created, and monitored, turning schedules were addressed, and a wound, ostomy, and continence (WOC) nurse and support staff were hired. These initial interventions …

The Effect Of Antagonist Muscle Sensory Input On Force Regulation, Tanya Onushko, Brian D. Schmit, Allison S. Hyngstrom

Physical Therapy Faculty Research and Publications

The purpose of this study was to understand how stretch-related sensory feedback from an antagonist muscle affects agonist muscle output at different contraction levels in healthy adults. Ten young (25.3 ± 2.4 years), healthy subjects performed constant isometric knee flexion contractions (agonist) at 6 torque levels: 5%, 10%, 15%, 20%, 30%, and 40% of their maximal voluntary contraction. For half of the trials, subjects received patellar tendon taps (antagonist sensory feedback) during the contraction. We compared error in targeted knee flexion torque and hamstring muscle activity, with and without patellar tendon tapping, across the 6 torque levels. At lower torque …
