On The Reliability Of Wearable Sensors For Assessing Movement Disorder-Related Gait Quality And Imbalance: A Case Study Of Multiple Sclerosis, Steven Díaz Hernández

USF Tampa Graduate Theses and Dissertations

Approximately 33 million American adults had a movement disorder associated with medication use, ear infections, injury, or neurological disorders in 2008, with over 18 million people affected by neurological disorders worldwide. Physical therapists assist people with movement disorders by providing interventions to reduce pain, improve mobility, avoid surgeries, and prevent falls and secondary complications of neurodegenerative disorders. Current gait assessments used by physical therapists, such as the Multiple Sclerosis Walking Scale, provide only semi-quantitative data, and cannot assess walking quality in detail or describe how one’s walking quality changes over time. As a result, quantitative systems have grownas useful tools …

Therapists’ Perceptions Of The Carroll Upper Extremity Function Test To Measure Functional Outcomes Post-Hand Allotransplantation Based On Lived Experience, Jyoti Heiple

Graduate Theses, Dissertations, and Capstones

Hand allotransplantation is a treatment option available for individuals who have suffered a traumatic upper extremity injury. To date, there is not an industry-standard recognized measurement tool for assessing post-hand allotransplantation functional performance. A commonly used observational functional assessment tool is the Carroll Upper Extremity Function Test (UEFT). This dissertation explores therapists’ perceptions of the Carroll UEFT applicability to measure functional outcomes post-hand allotransplantation. The study employed a qualitative phenomenological approach with in-depth, semi-structured interviews with seven occupational and physical therapists representing five hand transplant centers in the United States. Braun and Clarke’s (2006) six-phase thematic analysis approach was utilized …

Task-Based Functional Connectivity And Blood-Oxygen-Level-Dependent Activation During Within-Scanner Performance Of Lumbopelvic Motor Tasks: A Functional Magnetic Resonance Imaging Study, Mark K. Jordon, Jill Campbell Stewart Pt,Phd, Sheri P. Silfies, Paul F. Beattie

Faculty Publications

There are a limited number of neuroimaging investigations into motor control of the lumbopelvic musculature. Most investigation examining motor control of the lumbopelvic musculature utilize transcranial magnetic stimulation (TMS) and focus primarily on the motor cortex. This has resulted in a dearth of knowledge as it relates to how other regions of the brain activate during lumbopelvic movement. Additionally, task-based functional connectivity during lumbopelvic movements has not been well elucidated. Therefore, we used functional magnetic resonance imaging (fMRI) to examine brain activation and ROI-to-ROI task-based functional connectivity in 19 healthy individuals (12 female, age 29.8 ± 4.5 years) during the …

Degenerative Cervical Myelopathy Delays Responses To Lateral Balance Perturbations Regardless Of Predictability, T. F. Boerger, L. Mcginn, M. C. Wang, Brian D. Schmit, Allison S. Hyngstrom

Physical Therapy Faculty Research and Publications

The aim of this study was to quantify balance impairments in standing in people with degenerative cervical myelopathy (PwDCM) in response to external perturbations. PwDCM have damage to their spinal cord due to degeneration of the cervical vertebral column, but little is known about balance. Balance was quantified by capturing kinetics, kinematic, and electromyographic data during standing in response to lateral waist pulls. Participants received pulls during predictable and unpredictable contexts in three stance widths at two magnitudes. In response to lateral waist pulls, PwDCM had larger center of mass excursion (P < 0.001) and delayed gluteus medius electromyography onset (P < 0.001) and peak (P < 0.001) timing. These main effects of history of myelopathy were consistent across predictability, stance width, and magnitude. A multilinear regression determined that gluteus medius peak timing + tibialis anterior peak timing most strongly predicted center of mass excursion (R2 = 0.50, P < 0.001). These data suggest that PwDCM have delays in generating voluntary and reactive motor commands, contributing to balance impairments. Future rehabilitation strategies should focus on generating rapid muscular contractions. Additionally, frontal plane postural control is regulated by the gluteus medius and the tibialis anterior, whereas other muscles (e.g. gluteus minimus, ankle invertors/evertors) not studied here may also contribute.

Improving Prediction Of Amyloid Deposition In Mild Cognitive Impairment With A Timed Motor Task, Sydney Y. Schaefer, Kevin Duff, Andrew Hooyman, John M. Hoffman

Physical Therapy Faculty Articles and Research

Cortical amyloid deposition is one of the hallmark biomarkers of Alzheimer’s disease (AD). However, given how cost- and time-intensive amyloid imaging can be, there is a continued need for a low-cost, non-invasive, and accessible enrichment strategy to pre-screen individuals for their likelihood of amyloid prior to imaging. Previous work supports the use of coordinated limb movement as a potential screening tool, even after controlling for cognitive and daily function. Thirty-six patients diagnosed with amnestic mild cognitive impairment over the age of 65 underwent 18F-Flutemetamol amyloid-positron emission tomography Cortical amyloid deposition is one of the hallmark biomarkers of Alzheimer’s disease (AD). …

Simmons, Douglas E. Long, Kate Kosmac, Cory M. Dungan, Philip A. Kern, Marcas M. Bamman, Charlotte A. Peterson

Center for Muscle Biology Faculty Publications

The extracellular matrix (ECM) in skeletal muscle plays an integral role in tissue development, structural support, and force transmission. For successful adaptation to mechanical loading, remodeling processes must occur. In a large cohort of older adults, transcriptomics revealed that genes involved in ECM remodeling, including matrix metalloproteinase 14 (MMP14), were the most upregulated following 14 weeks of progressive resistance exercise training (PRT). Using single-cell RNA-seq, we identified macrophages as a source of Mmp14 in muscle following a hypertrophic exercise stimulus in mice. In vitro contractile activity in myotubes revealed that the gene encoding cytokine leukemia inhibitory factor ( …
