Age-Related Balance Control Changes In Constrained-Speed Gait During A Concurrent Cognitive Task, Raymond Chong, Victoria Moore, Hope Brown Sampson, Heather Spears, Manh-Cuong Do

Asian Journal of Physical Therapy

Background: During walking, the center of mass (CoM) oscillates up and down in the sagittal plane. In the late-stance phase, as the CoM descends, its vertical velocity decreases before foot contact, indicating active neural balance control, which we refer to as CoM braking. Young adults tend to increase braking while maintaining step length and speed when performing a cognitive task, such as subtracting numbers. In contrast, older adults maintain consistent braking by reducing step length and speed. This study examined the effects of walking at constant self-selected, slower, or faster speeds on CoM braking and cognitive performance. Methods: Healthy young …

• Upwards of 15% of individuals infected with SARS-CoV-2 may develop “Long COVID” with persistent physical, cognitive, and/or mental symptoms potentially amendable to occupational therapy.
• Variability exists in the rehabilitation approach for individuals receiving occupational therapy for this novel condition.
• Clinical practice guidelines (CPGs) and other evidence-based resources exist to help standardized rehabilitation; however, it is unknown if occupational therapists (OTs) are aware of these resources and applying them in the management of individuals with Long COVID.
• We surveyed OTs in the contiguous United States (U.S.) to explore their awareness and application of Long COVID CPGs along with …

Two-Year Follow-Up Of Gait And Postural Control Following Initiation Of Recombinant Human Tripeptidyl Intracerebroventricular Enzyme Replacement Therapy In Two Atypical Cln2 Patients, Rahul Soangra, Marybeth Grant-Beuttler, Harriet Chang, Raymond Y. Wang

Physical Therapy Faculty Articles and Research

Neuronal ceroid lipofuscinosis type 2 (CLN2) is a rapidly progressive neurodegenerative disorder leading to premature mortality. Ambulatory CLN2 patients typically receive standard of care treatment through biweekly intracerebroventricular (ICV) enzyme replacement therapy (ERT) involving recombinant human tripeptidyl peptidase 1, known as cerliponase alfa (Brineura^®, Biomarin Pharmaceuticals). This study longitudinally assessed the impact of ICV cerliponase alfa ERT on gait, and postural control across a two-year span in two siblings diagnosed with atypical CLN2 disease. Both participants, ID01 (18 years and 8 months old at enrollment) and ID02 (13 years and 3 months old at enrollment), exhibited symptomatic characteristics …

Incorporating Mindfulness Techniques In Therapeutic Practices To Impact A Patient’S Pain Perception, Abigail E. Masters

2025 Honors Symposium

Background: Chronic pain is a widespread condition that affects millions of individuals and leads to substantial healthcare costs, with estimates in the U.S. ranging from $560 billion to $635 billion annually. Traditional pain management heavily relies on opioid prescriptions, which, while effective in the short term, have contributed to the ongoing opioid crisis due to risks of addiction and dependency. As a result, there is a growing interest in alternative, non- pharmacological approaches to pain management, including mindfulness-based interventions (MBIs). MBIs have been increasingly recognized for their ability to help patients modulate pain perception and improve overall well-being. This study …

Caregiver Perceptions Of Gobabygo Car Usage, Sierra L. Hays, Erin L. Hefner, Richelle Gray, Carrie Smith-Bell

Graduate Student Scholarship

This qualitative study aims to understand caregiver perceptions of their child’s play using a modified ride-on toy car (MROC). Caregivers of children with disabilities participated in a semi-structured interview and a photo-elicitation interview to better understand their beliefs, attitudes, values, and feelings about their children’s play with a MROC. A directed content analysis was used based on constructs of the model for the Process for Establishing Children’s Occupations (PECO; Wiseman et al., 2005). Most constructs of the PECO model, including stages of play and influences on play, were identified within the caregivers’ descriptions of children's play with the MROC. Additional …

Exploring Law Enforcement Officers' Experiences With Athletic Trainers And Work-Related Injury, Stephanie H. Clines, Rubie Gaudette, Amanda Wheeler, Jennifer Ostrowsk

Athletic Training Faculty Publications

Law enforcement is an emerging clinical setting for athletic trainers (ATs), yet little is known regarding law enforcement officers (LEOs) perceptions of the profession. This qualitative study following a general inductive approach explored LEOs' experiences with musculoskeletal injury and their interactions with ATs. Seven officers (N = 7) participated in one-on-one semi-structured interviews. Three themes emerged: (1) roles and responsibilities of ATs, (2) education and training, and (3) impact of injury on LEOs. While participants viewed ATs positively, they demonstrated limited understanding of the profession's scope and expertise. Participants commonly described managing musculoskeletal injuries on their own due to …

Results: Significant improvements in …

Mental Health And Belongingness Of Doctor Of Physical Therapy Students: A Mixed Methods Study Centering Black Student Voices, Robyn Redline

Graduate Research Theses & Dissertations

Background: Despite efforts to increase recruitment and enrollment, the physical therapy profession lacks Black students and clinicians. Racially marginalized students have higher rates of academic difficulty during physical therapy education (PTE) than White students. Mental health and belongingness have been proposed as prerequisites for reaching academic achievement and attaining one’s full potential. Conversely, poor mental health and lack of belongingness during PTE may contribute to the underrepresentation of Black Doctor of Physical Therapy (DPT) students and clinicians. Yet not enough is known about the relationships between mental health, belongingness, and the academic achievement of DPT students. Purpose: This study aimed …

Optimizing Decision-Making In A Cerebral Palsy Model Using Reinforcement Learning, Richard Ampah

Pitzer Senior Theses

This study presents an original interdisciplinary investigation into how reinforcement learning (RL) can model motor and cognitive defects and potentially improve motor and cognitive functions in individuals with cerebral palsy (CP), a non-progressive neurological disorder that impairs movement and adaptability. Integrating computational neuroscience and machine learning, the research applies policy gradient methods and Markov Decision Processes (MDPs) to simulate adaptive learning in agents with and without CP-related constraints.

The central aim is to compare the cumulative rewards of optimal policies, derived from value iteration, and human-like learning policies using the REINFORCE algorithm, both with and without the Bellman baseline. The …

Development And Clinical Validation Of The Sensor-E Exoskeleton For Objective Hand Function Assessment In Stroke Rehabilitation, Madison Bates

Theses and Dissertations--Biomedical Engineering

Hand function is often impaired following neurological trauma or in conditions such as stroke, limiting independence and the ability to perform activities of daily living (ADLs). Current clinical assessments rely heavily on subjective rating scales that lack the resolution to detect subtle changes in motor performance, which can limit access to rehabilitation. Recent advances in wearable technologies highlight the potential for hand-worn devices to provide objective, real-time measures of hand function. However, most systems focus solely on kinematics and rarely capture both movement and exerted force. Moreover, integration into rehabilitation frameworks and brain-computer interface (BCI) protocols remains limited. To address …

Commentary On “Predictors Of Length Of Physical Therapy Care For Infants With Congenital Torticollis”, Ryan Jacobson, Kathryn Knudsen, Katherine Binkerd

Faculty Publications - College of Physical Therapy

Most infants in this study were ≤3 months of age and 94% had severity grades I or II. Clinicians might prioritize accurately measuring active neck rotation using an arthrodial goniometer in younger, less severe infants, since active neck rotation deficit had the highest single-factor correlation with episode length and reflects degree of asymmetry in neck and torso strength. While the Alberta Infant Motor Scale and previous tummy/container time factors were not associated, we appreciate the efforts of the authors to address this gap in the literature.

Hopping Kinetic Differences In Masters Runners With And Without Achilles Tendinopathy, Matthew Klein, Chris Patterson, Annette Karim, Tyler Cuddeford

Faculty Publications - College of Physical Therapy

Achilles tendinopathy (AT) is the most common running-related pathology among masters runners. Previous evidence suggests there are no differences in submaximal running biomechanics between masters runners with and without AT. Evidence suggests lower extremity power deficits are common among ageing individuals and those with AT. The single-leg horizontal hop (SLHH) test isa valid and reliable lower extremity power test. The purpose of this study was to investigate differences in SLHH biomechanics between masters runners with and without AT. 32 masters runners age 50 and older with AT (60.31 ± 8.37, n = 16) and without (59.94 ±4.95 n = 16) …

The Interplay Between Pulse Width And Activation Depth In Tens: A Computational Study, Alexander Guillen, Dennis Q Truong, Yusuf O Cakmak, Sheng Li, Abhishek Datta

Faculty, Staff and Student Publications

Background: Transcutaneous electrical nerve stimulation (TENS) has been a commonly used modality to relieve aches and pain for over 40 years. Commercially available devices provide multiple therapy modes involving a different combination of frequency and pulse width with intensity. While frequency sets sensation, intensity helps determine tolerability, longer pulse width is reported to induce a feeling of deeper stimulation. In fact, longer pulse width has been empirically shown to deliver current into deeper tissues, but in context of other electrical stimulation modalities. The goal of this study was to unpack the relationship between pulse width and activation depth in TENS. …

Evaluation Of Therapist Modeling To Decrease Latency To Exercise Initiation, Darci L. Davis, Kayla Randall

Honors College Theses

Patients recovering from traumatic brain injury (TBI) or other adverse health events (e.g., hip surgery) often require physical therapy (PT) to restore baseline function. However, individuals with mild cognitive impairment (MCI) or dementia may have difficulty engaging in therapy due to deficits in attention, imitation skills, and motor performance. Enhancing participation in this population is essential for achieving functional recovery and return to baseline status. This study aimed to determine whether systematic model prompting could decrease latency to compliance and increase the level of completion of therapeutic exercises in short-term rehabilitation settings. A multiple-baseline single-case design with time-lagged and staggered …

Exploring Anterior Cruciate Ligament Tears: Causes, Reconstruction, And Outcomes, Holly L. Bollinger

Honors College Theses

The anterior cruciate ligament (ACL) is a critical structure in knee stability, and its injury can significantly impair athletic performance and daily functionality. The ACL plays a vital role in stabilizing the knee joint, preventing excessive forward movement of the tibia relative to the femur and aiding in rotational control. ACL tears are commonly associated with sports and physical activities that involve sudden stops, pivots, or changes in direction. These injuries can lead to knee instability, impaired function, and long-term complications. Despite the prevalence of ACL tears, there remains a lack of consensus on the multifactorial causes, optimal reconstruction techniques, …

Ankle Dorsiflexion Range Of Motion And Its Association With Semi-Professional Female Soccer Player's Overall Performance, Lily G. Nolan

Honors College Theses

Lower extremity injury screening is a common tool in soccer due to the changes of direction, jumping, landing, and cutting maneuvers players must exhibit. Talocrural dorsiflexion range of motion (DFROM), vertical jump (VJ) and unilateral hop tests are used to assess ankle and knee injury risk. Further, DFROM asymmetries may present a higher risk than reduced DFROM alone. It is unknown how DFROM asymmetries affect these tests. Thus, the purpose of this study was to examine the relationship between DFROM and hop and VJ performance, and to examine the differences between those with and without DFROM asymmetries. The current results …

The Impact Of Professionalism Education And Formative Feedback In Doctor Of Physical Therapy Students Utilizing The Abbreviated Cpi Feedback Form In The On-Campus Clinic Environment, William L. Scott

Dissertations

Problem

The American Physical Therapy Association (APTA) developed the Clinical Performance Instrument (CPI) to assess the professional behaviors required for a Doctor of Physical Therapy (DPT) student to be considered "entry level" in their clinical training. Feedback from our clinical partners has indicated that, historically, students from the Andrews University DPT program have scored lower than students from other programs in several areas of the CPI during their clinical experiences. According to subjective reports from our clinical partners, these areas included safety, professional behavior, accountability, communication, and critical thinking. These five areas have been the focus of our efforts in …
