Barriers To Exercise And Physical Activity - Insight From The Rural Practitioner, Erin G. Tillery

Honors College Theses

Sedentary lifestyles are a growing public health concern. Furthermore, many rural Americans lack adequate access to healthcare resources. When healthcare is sought, the patient-practitioner interactions may serve to influence the patient’s lifestyle choices. The practitioners' exercise and physical activity habits may shape the effectiveness of the patient-practitioners interaction. Here, we explored the potential barriers to exercise and physical activity (PA) in licensed physical and occupational therapists. In addition, we aimed to describe barriers to exercise and PA in individuals with a history of stroke from the perspective of the practitioner. Lastly, how current exercise and physical activity habits influence their …

Quantifying Intra- And Interlimb Use During Unimanual And Bimanual Tasks In Persons With Hemiparesis Post-Stroke, Susan V. Duff, Aaron Miller, Lori Quinn, Gregory Youdan Jr., Lauri Bishop, Heather Ruthrauff, Eric Wade

Physical Therapy Faculty Articles and Research

Background

Individuals with hemiparesis post-stroke often have difficulty with tasks requiring upper extremity (UE) intra- and interlimb use, yet methods to quantify both are limited.

Objective

To develop a quantitative yet sensitive method to identify distinct features of UE intra- and interlimb use during task performance.

Methods

Twenty adults post-stroke and 20 controls wore five inertial sensors (wrists, upper arms, sternum) during 12 seated UE tasks. Three sensor modalities (acceleration, angular rate of change, orientation) were examined for three metrics (peak to peak amplitude, time, and frequency). To allow for comparison between sensor data, the resultant values were combined into …

Visualization-Driven Time-Series Extraction From Wearable Systems Can Facilitate Differentiation Of Passive Adl Characteristics Among Stroke And Healthy Older Adults, Joby John, Rahul Soangra

Physical Therapy Faculty Articles and Research

Wearable technologies allow the measurement of unhindered activities of daily living (ADL) among patients who had a stroke in their natural settings. However, methods to extract meaningful information from large multi-day datasets are limited. This study investigated new visualization-driven time-series extraction methods for distinguishing activities from stroke and healthy adults. Fourteen stroke and fourteen healthy adults wore a wearable sensor at the L5/S1 position for three consecutive days and collected accelerometer data passively in the participant’s naturalistic environment. Data from visualization facilitated selecting information-rich time series, which resulted in classification accuracy of 97.3% using recurrent neural networks (RNNs). Individuals with …

Kinematic Analysis Of 360° Turning In Stroke Survivors Using Wearable Motion Sensors, Masoud Abdollahi, Pranav Madhav Kuber, Michael Shiraishi, Rahul Soangra, Ehsan Rashedi

Physical Therapy Faculty Articles and Research

Background: A stroke often bequeaths surviving patients with impaired neuromusculoskeletal systems subjecting them to increased risk of injury (e.g., due to falls) even during activities of daily living. The risk of injuries to such individuals can be related to alterations in their movement. Using inertial sensors to record the digital biomarkers during turning could reveal the relevant turning alterations. Objectives: In this study, movement alterations in stroke survivors (SS) were studied and compared to healthy individuals (HI) in the entire turning task due to its requirement of synergistic application of multiple bodily systems. Methods: The motion of 28 participants (14 …

Effects Of Quadruped Movement In An Individual With Chronic Stroke: A Case Study, Maureen Romanow Pascal, Emily Connell, Alyssa Pratti, Kristina Russell

Student Research Poster Presentations 2022

Background/Purpose: Neuromuscular dysfunction encompasses a wide variety of conditions that impact proper muscle functioning. One common condition resulting in neuromuscular dysfunction is a cerebrovascular accident (CVA) which can disrupt sensory, motor, visual and language systems. The resulting combination of impairments can cause limitations in activity performance and restrict participation across domains. In addition, muscle weakness is widely recognized as a major contributing factor to decline in function. Literature is showing that rehabilitation programs focusing on development of core strength with emphasis on repetition, intensity and novelty are critical for recovery of motor function. The purpose of this research was to …

Different Biomechanical Variables Explain Within-Subjects Versus Between-Subjects Variance In Step Length Asymmetry Post-Stroke, Natalia Sánchez, Nicolas Schweighofer, James M. Finley

Physical Therapy Faculty Articles and Research

Step length asymmetry (SLA) is common in most stroke survivors. Several studies have shown that factors such as paretic propulsion can explain between-subjects differences in SLA. However, whether the factors that account for between-subjects variance in SLA are consistent with those that account for within subjects, stride-by-stride variance in SLA has not been determined. SLA direction is heterogeneous, and different impairments likely contribute to differences in SLA direction. Here, we identified common predictors between-subjects that explain within-subjects variance in SLA using sparse partial least squares regression (sPLSR). We determined whether the SLA predictors differ based on SLA direction and whether …

Development And Feasibility Of A Modified Fugl-Meyer Lower Extremity Assessment For Telerehabilitation: A Pilot Study., Sue Peters, Marcela Botero, Allison Evers, Brianna Fong, Botond Jakab, Emily Petter, Janice J Eng

Physical Therapy Publications

BACKGROUND: The majority of stroke survivors experience motor impairment which benefits from rehabilitation treatment. Telerehabilitation, remote delivery of rehabilitation services, is a possible solution providing access to rehabilitation for stroke survivors living in rural areas or in situations like the COVID-19 pandemic where face-to-face treatment may be risky. However, valid and reliable motor impairment measures have not yet been established over a telerehabilitation platform. The Fugl-Meyer (FM) lower extremity assessment is widely used clinically and in research. Thus, the aim was to develop a modified FM for telerehabilitation (FM-tele) and assess the feasibility and preliminary agreement of FM-tele scores with …

Using Biofeedback To Reduce Spatiotemporal Asymmetry Impairs Dynamic Balance In People Post-Stroke, Sungwoo Park, Chang Liu, Natalia Sánchez, Julie K. Tilson, Sara J. Mulroy, James M. Finley

Physical Therapy Faculty Articles and Research

Background. People poststroke often walk with a spatiotemporally asymmetric gait, due in part to sensorimotor impairments in the paretic lower extremity. Although reducing asymmetry is a common objective of rehabilitation, the effects of improving symmetry on balance are yet to be determined. Objective. We established the concurrent validity of whole-body angular momentum as a measure of balance, and we determined if reducing step length asymmetry would improve balance by decreasing whole-body angular momentum. Methods. We performed clinical balance assessments and measured wholebody angular momentum during walking using a full-body marker set in a sample of 36 people with …

Lost In Translation: Simple Steps In Experimental Design Of Neurorehabilitation-Based Research Interventions To Promote Motor Recovery Post-Stroke, Natalia Sánchez, Carolee J. Winstein

Physical Therapy Faculty Articles and Research

Stroke continues to be a leading cause of disability. Basic neurorehabilitation research is necessary to inform the neuropathophysiology of impaired motor control, and to develop targeted interventions with potential to remediate disability post-stroke. Despite knowledge gained from basic research studies, the effectiveness of researchbased interventions for reducing motor impairment has been no greater than standard of practice interventions. In this perspective, we offer suggestions for overcoming translational barriers integral to experimental design, to augment traditional protocols, and re-route the rehabilitation trajectory toward recovery and away from compensation. First, we suggest that researchers consider modifying task practice schedules to focus on …

Physical Therapy Publications

OBJECTIVE: To determine the publication rate of motor-rehabilitation trials poststroke and the consistency between registry records and their corresponding main publications in trial design, primary objectives and outcomes, eligibility criteria, and sample size.

METHODS: We searched 18 clinical trial registries to identify randomized controlled trials of motor-based stroke rehabilitation registered after July 2005 and completed before April 2017. Eligible trials included adults with stroke, with at least one outcome measure related to motor function. Information in the registry records was compared with that of their main publications, if any.

RESULTS: Three hundred twenty-three trials met our eligibility criteria; we were …

A Feasibility Study Of Expanded Home-Based Telerehabilitation After Stroke, Steven C. Cramer, Lucy Dodakian, Vu Le, Alison Mckenzie, Jill See, Renee Augsburger, Robert J. Zhou, Sophia M. Raefsky, Thalia Nguyen, Benjamin Vanderschelden, Gene Wong, Daniel Bandak, Laila Nazarzai, Amar Dhand, Walt Scacchi, Jutta Heckhausen

Physical Therapy Faculty Articles and Research

Introduction: High doses of activity-based rehabilitation therapy improve outcomes after stroke, but many patients do not receive this for various reasons such as poor access, transportation difficulties, and low compliance. Home-based telerehabilitation (TR) can address these issues. The current study evaluated the feasibility of an expanded TR program.

Methods: Under the supervision of a licensed therapist, adults with stroke and limb weakness received home-based TR (1 h/day, 6 days/week) delivered using games and exercises. New features examined include extending therapy to 12 weeks duration, treating both arm and leg motor deficits, patient assessments performed with no therapist supervision, adding sensors …

Social Network Structure Is Related To Functional Improvement From Home-Based Telerehabilitation After Stroke, Archana Podury, Sophia M. Raefsky, Lucy Dodakian, Liam Mccafferty, Vu Le, Alison Mckenzie, Jill See, Robert J. Zhou, Thalia Nguyen, Benjamin Vanderschelden, Gene Wong, Laila Nazarzai, Jutta Heckhausen, Steven C. Cramer, Amar Dhand

Physical Therapy Faculty Articles and Research

Objective: Telerehabilitation (TR) is now, in the context of COVID-19, more clinically relevant than ever as a major source of outpatient care. The social network of a patient is a critical yet understudied factor in the success of TR that may influence both engagement in therapy programs and post-stroke outcomes. We designed a 12-week home-based TR program for stroke patients and evaluated which social factors might be related to motor gains and reduced depressive symptoms.

Methods: Stroke patients (n = 13) with arm motor deficits underwent supervised home-based TR for 12 weeks with routine assessments of motor function and …

Faculty Publications

Background

Cardiac rehabilitation (CR) is a structured exercise program prevalent in the United States for people with cardiovascular disease that has been shown to increase cardiovascular endurance and improve quality of life. Despite similar cardiovascular risk factors, stroke is not among the covered diagnoses for CR. The purpose of this study was to examine the participant impact of integrating survivors of stroke into the exercise portion of an existing hospital‐based CR program through measures of physical function and other health impacts and through qualitative evaluation of participant perception.

Methods and Results

Subacute and chronic survivors of stroke were integrated into …

Biomechanically Inspired Assistive Technology To Restore Movement Of The Upper Limbs After Stroke, Ariel Thomas

Graduate Theses, Dissertations, and Problem Reports (ETD)

A stroke often damages the neural structures responsible for movement. Stroke is a heterogeneous disease, affecting each survivor differently. There are common motor features of a stroke, but even these features vary across time as an individual proceeds through different stages of recovery. The different ways in which stroke motor impairment can present itself are often overlooked, but these differences are fundamental to the understanding of the disease and its recovery. When motor assessments are capable of acquiring information necessary to parse out a detailed profile of each stroke case, this will lead to an improved neuromechanical understanding of the …

Targeted Engagement Of The Action Selection Network During Task-Oriented Arm Training After Stroke, Jill Campbell Stewart Pt,Phd, Kaci Handlery, Jessica F. Baird, Erika L. Blanck, Geetanjali Pathak, Stacy L. Fritz

Faculty Publications

Action selection (AS), or selection of an action from a set of alternatives, is an important movement preparation process that engages a frontal-parietal network. The addition of AS demands to arm training after stroke could be used to engage this motor planning process and the neural network that supports it. The purpose of this case series is to describe the feasibility and outcomes associated with task-oriented arm training aimed at engaging the AS behavioral process and the related neural network in three individuals with chronic stroke. Three participants with mild to moderate motor deficits completed 13 to 15 sessions of …

Post-Stroke Cognitive Impairments And Responsiveness To Motor Rehabilitation: A Review, Jennapher Lingo Vangilder, Andrew Hooyman, Daniel S. Peterson, Sydney Y. Schaefer

Physical Therapy Faculty Articles and Research

Purpose of Review
This review discusses the prevalence of cognitive deficits following stroke and their impact on responsiveness to therapeutic intervention within a motor learning context.

Recent Findings
Clinical and experimental studies have established that post-stroke cognitive and motor deficits may impede ambulation, augment fall risk, and influence the efficacy of interventions. Recent research suggests the presence of cognitive deficits may play a larger role in motor recovery than previously understood.

Summary
Considering that cognitive impairments affect motor relearning, post-stroke motor rehabilitation therapies may benefit from formal neuropsychological testing. For example, early work suggests that in neurotypical adults, cognitive function …

The Effects Of Somatosensory Input On Gait In Individuals Post-Stroke, Victor Hung, Amanda Reilly, Rachel Wood, Nikita Yuskov

UNLV Theses, Dissertations, Professional Papers, and Capstones

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 …

Functional Mobility In A Patient With Antiphospholipid Antibody Syndrome Following A Femoral Neck Fracture Surgical Repair: A Case Report, Mckenna Young

Case Report Papers

Background and Purpose: The main focus of chronic disease in healthcare has typically been about treatment of the disease itself, with little attention given to secondary injuries that result from the chronic disease process. As these individuals age, the risk of secondary injuries increases. This is costly and adds to the caregiver burden. The purpose of this case report was to investigate a comprehensive physical therapy (PT) program focused on rehabilitation for a female with chronic disease who sustained a femoral fracture following her most recent fall. Case Description: A 42-year-old female presented to outpatient PT following a right femoral …

Tissue Plasminogen Activator Effects On Stroke And Physical Therapy Outcomes In Acute Care: A Case Report, Lindsey Leboeuf

Case Report Papers

Background and Purpose: An ischemic stroke occurs when blood flow to an area of the brain is restricted and can cause numbness or weakness on one side of the body, facial droop, trouble speaking, and trouble walking. Patients who seek medical attention for symptoms within three hours of their onset can be eligible to receive tissue plasminogen activator (tPA). These patients often have less resultant disability than their counterparts who did not receive the drug. The purpose of this case reports is to display the positive effects of tPA and physical rehabilitation following a stroke in the acute care setting. …

Use Of Standardized Assessments And Online Resources In Stroke Rehabilitation, Susan H. Lin, Pamela R. Bosch, Veronica T. Rowe, Susan E. Fasoli, Jeanne Langan

The Open Journal of Occupational Therapy

Background: The extent to which movement-related standardized assessments and online resources are used in stroke rehabilitation is unclear in the United States.

Method: The researchers used a cross-sectional descriptive survey that examined (a) therapists use of movement-related standardized assessments, (b) factors influencing learning of new assessments, and (c) use of frequency of online resources by occupational therapists and physical therapists in the United States.

Results: Of 151 respondents (46.4% occupational therapists, 53.6% physical therapists), the most frequently used movement-related assessments by occupational and physical therapists were the Berg and Fugl-Meyer Assessment, respectively. More physical therapists use motor-related …

Engineering Technology Faculty Publications

We present the design and validation of a low-cost, customizable and 3D-printed anthropomorphic soft robotic hand exoskeleton for rehabilitation of hand injuries using remotely administered physical therapy regimens. The design builds upon previous work done on cable actuated exoskeleton designs by implementing the same kinematic functionality, but with the focus shifted to ease of assembly and cost effectiveness as to allow patients and physicians to manufacture and assemble the hardware necessary to implement treatment. The exoskeleton was constructed solely from 3D-printed and widely available of-the-shelf components. Control of the actuators was realized using an Arduino microcontroller, with a custom-designed shield …

Temporal And Functional Cortical Aspects Related To Mirror Visual Feedback During Target-Directed Movement In Healthy And Stroke Individuals, Maryam Rohafza

Dissertations

Stroke is the leading cause of disability in the United States (American Heart Association, American Stroke Association) affecting 800,000 individuals annually (i.e., one person every 45 seconds). Therapy for stroke often uses repetitive task practice, which is difficult to perform for patients due to impairment. Mirror visual feedback (MVF) based rehabilitation uses the effect of observing the mirror reflection of volitional movement of one limb, to activate visuomotor brain areas that process movement of the opposite limb. In persons with hemiplegia due to stroke, exercising the less affected limb while observing its reflection, perceived by them as the motion of …

Modulation Of Corticospinal Excitability Using Cathodal Transcranial Direct Current Stimulation To Improve Walking In Individuals With Chronic Post Stroke Hemiparesis, Neil Drobitch, Kylie Henry, Sage Lyons, James Schomig

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Individuals who have experienced a pyramidal cerebrovascular accident (pCVA) often exhibit impairments to volitional control of corresponding motor tasks. Promising effects in motor response, post-application of transcranial direct current stimulation (tDCS), have been reported in studies on individuals with the ability to achieve independent gait for 20 minutes. These studies mainly examined the effects of combined tDCS with locomotor training on lower extremity function among higher functioning individuals post-stroke. The purpose of this study was to determine the effect of tDCS among individuals post-stroke who may not have independent ambulatory capabilities, focusing on motor response and less …

Neurodynamics Under Different Walking Speeds In Individuals With Chronic Post-Stroke Hemiparesis, Corey Ackley, Kiley Aki, Joshua Arias, Jassie Trinh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Stroke is the leading cause of long-term disability in adults worldwide. The ability to return to walking is often a main goal of rehabilitation in individuals with chronic post-stroke hemiparesis. To increase walking speed, non-neurologically impaired individuals produce greater ankle propulsion force at push-off with greater ankle dorsiflexion angles in swing phase with no change in ankle muscle co-contraction index in the swing phase. It remains unclear if individuals post-stroke would adopt similar neuromuscular strategies. Therefore, our aim was to examine the effect of altered walking speeds on propulsion force at push-off, ankle dorsiflexion angle during swing, …

White Matter Biomarkers Associated With Motor Change In Individuals With Stroke: A Continuous Theta Burst Stimulation Study, K P Wadden, Sue Peters, M R Borich, J L Neva, K S Hayward, C S Mang, N J Snow, K E Brown, T S Woodward, S K Meehan, L A Boyd

Physical Therapy Publications

Continuous theta burst stimulation (cTBS) is a form of noninvasive repetitive brain stimulation that, when delivered over the contralesional hemisphere, can influence the excitability of the ipsilesional hemisphere in individuals with stroke. cTBS applied prior to skilled motor practice interventions may augment motor learning; however, there is a high degree of variability in individual response to this intervention. The main objective of the present study was to assess white matter biomarkers of response to cTBS paired with skilled motor practice in individuals with chronic stroke. We tested the effects of stimulation of the contralesional hemisphere at the site of the …

The Tailoring Of National Guidelines For Upper Extremity Post-Stroke Rehabilitation: A Concept In Use., Salem F. Alatawi

Internet Journal of Allied Health Sciences and Practice

Background: In Saudi Arabia, national evidence-based clinical guidelines (NCG) were created based for healthcare interventions. However, clinicians appear to be slow to incorporate the evidence into practice. As a result, there exists a time-gap between the gathering and presentation of evidence for best practice and the use of that evidence by clinicians. It becomes, therefore, imperative to investigate the gap between the research evidence and clinical practice. The knowledge to action (KTA) framework is available to facilitate the implementation of research evidence. This framework incorporates the theory of tailoring, a concept that is intended to create a fit between …

Strength, balance, gait speed, and functional tasks all improved over the course of physical therapy. At the end of 2 weeks, the patient exceeded the minimal detectable change (MDC) for the TUG (2.9 sec) and achieved the minimal clinically important difference (MCID) for the FIM (22 points).^4-5 Although the MCID is not established for the Modified Ashworth Scale (MAS), the patient experienced improvements …

Neural Constraints Affect The Ability To Generate Hip Abduction Torques When Combined With Hip Extension Or Ankle Plantarflexion In Chronic Hemiparetic Stroke, Natalia Sánchez, Ana M. Acosta, Roberto López-Rosado, Julius P. A. Dewald

Physical Therapy Faculty Articles and Research

Stroke lesions interrupt descending corticofugal fibers that provide the volitional control of the upper and lower extremities. Despite the evident manifestation of movement impairments post-stroke during standing and gait, neural constraints in the ability to generate joint torque combinations in the lower extremities are not yet well determined. Twelve chronic hemiparetic participants and 8 age-matched control individuals participated in the present study. In an isometric setup, participants were instructed to combine submaximal hip extension or ankle plantarflexion torques with maximal hip abduction torques. Statistical analyses were run using linear mixed effects models. Results for the protocol combining hip extension and …
