Structural Sensorimotor Adaptations In Young Adults With Low Back Pain, Isaac Chrisman, Jo Armour Smith, Rongwen Tain, Kelli G. Sharp, Laura M. Glynn, Linda R. Van Dillen, Jesse V. Jacobs, Steven C. Cramer

Student Scholar Symposium Abstracts and Posters

Chronic low back pain (CLBP) is the largest cause of disability worldwide. There is evidence for regional structural brain adaptation in CLBP. Most studies have investigated middle-aged adults and show decreased grey matter density in pain processing regions. It is not clear if these adaptations are evident early in the lifespan of individuals with CLBP. The purpose of the study was to compare sensorimotor gray matter density in young adults with a history of CLBP with back-healthy controls. 53 young adults with a greater than 1-year history of CLBP and 29 young adults with no history of LBP participated. Clinical …

Spatiotemporal Gait Parameter Consistency Across Two Days Of Treadmill Walking In Stroke Survivors, Alejandro Aguirre Ramirez, Samantha N. Jeffcoat, Natalia Sanchez, Andrian Kuch

Student Scholar Symposium Abstracts and Posters

Retraining impaired gait is essential in post-stroke recovery. This project aims to determine between day variability of spatiotemporal gait measures in treadmill walking post-stroke to differentiate between changes due to the intervention and measurement errors due to between day test-retest variability. Six individuals post-stroke performed a two-minute walk test at a self-selected speed (SSS) for two consecutive days. SSS was assessed through the six-minute walk test. Reflective markers were placed on anatomical landmarks (van den Bogert et al. 2013). The heel markers were used for step detection. We calculated spatiotemporal parameters: stride length, stride time, step length, stance time, and …

Postural Control In Young Adults With And Without Recurrent Back Pain: Influence Of Symptom Characteristics, Rachel Berns

Student Scholar Symposium Abstracts and Posters

Many individuals with low back pain (LBP) experience episodic symptoms. During symptomatic episodes, individuals with LBP have delayed trunk muscle activation during anticipated postural perturbations, though it's unclear if these postural control changes persist between symptomatic episodes. This study examined anticipatory postural muscle activation in adults with and without recurrent LBP to determine the influence of muscle fatigue and typical symptom characteristics on trunk muscle activation. 55 young adults with a greater than one-year history of recurrent LBP and 30 young adults with no history of LBP were recruited. Electromyography electrodes were placed on their thoracic and lumbar paraspinals, external …

Augmenting Hand And Arm Function For Persons With Hemiparesis, Brooke Stein, Susan Duff, Alison Mckenzie, Bailey Advincula, Isaac An, Annie Jeon, Casey Mcwilliam, Will Potter, Virginia Ruano, Paulina Vokulich, Audrey Howell, Rahul Soangra

Student Scholar Symposium Abstracts and Posters

Background. Hand and arm dysfunction due to neural disorders significantly influences quality of life. Activity-based training has been found to improve function. These improvements could be augmented with transcutaneous spinal cord stimulation (tSCS) due to the modulatory effect it has on spinal and supraspinal networks. Objective. The primary aim is to determine if a 4-week training program will improve hand and arm function. The secondary aim is to determine if the addition of tSCS to a second 4-week training session will further improve function. Design. This is a pre-posttest, controlled trial for persons 10-75 years of age, >6 months post …

Identifying The Effects Of Function-Based Exercise On Postural Stability And Gait In Patients With Parkinson’S Disease, Kasey Markell, Rahul Soangra

Student Scholar Symposium Abstracts and Posters

This project seeks to identify a correlation between consistent, functional exercise and posture, balance, stability and gait in patients with Parkinson’s Disease (PD). PD is a neurodegenerative disease that decreases levels of dopamine in the Basal Ganglia of the brain, resulting in symptoms such as excessive freezing or erratic, involuntary movements, ultimately affecting a person’s ability to ambulate safely and independently. This study consisted of three main approaches to build a firm base of knowledge for this field of research. The first component was to test the limits of stability in healthy individuals for a baseline comparison to people with …

Central Modulation Of Postural Control In Response To Task Demands And Fatigue In Individuals With And Without A History Of Low Back Pain, Jolene Kay Soliman, Jo Armour Smith

Student Scholar Symposium Abstracts and Posters

Background During voluntary limb movement, feedforward postural activation of the trunk and hip musculature occurs to maintain postural stability. This is called an anticipatory postural adjustment (APA). Onset of trunk muscle APAs is delayed in symptomatic individuals with persistent low back pain (LBP). It is not clear how spatial APA organization is affected, or if adaptations in APAs persist between symptomatic episodes. We used two versions of a supine active leg raise task to examine central modulation of APAs. One version of the task, the supported leg raise (SLR) does not elicit trunk/hip APAs. The other, the unsupported leg raise …

Utilizing Teslasuit To Analyze Changes In Joint Angles And Galvanic Skin Responses During Slips (A Stress-Inducing Task), Olivia Johnson, Caitlin Ha, Audrey Arenal

Student Scholar Symposium Abstracts and Posters

When experiencing dangerous situations, humans have two different responses: fight or flight. During these moments, the sympathetic nervous system takes over and causes the body to work overtime to give the person the best chance at survival. Although the average person doesn’t face a life-or-death experience every day, slips are fairly common and can trigger this fight-or-flight response. Exploring what happens during a slip and quantifying a body’s response can be difficult. Still, with the help of motion capture suits and biometric sensors, there is a unique opportunity to learn more about the kinematics and physiological responses of the human …

Reliability Of Accelerometer-Based Reaction Time Tests, Jacob Hepp, Warner Rhodes, Jordan Walton, Rahul Soangra, Brent Harper

Student Scholar Symposium Abstracts and Posters

Concussions are traumatic brain injuries that affect the function of the brain. One of the primary symptoms of a concussion is a lack of reaction time. The people that are most susceptible to concussions are athletes; Laker’s (2011) study found that 135,000 patients that suffer concussions from playing sports are expected to be hospitalized each year, with football making up 75% of concussions at high school and college levels. Honda et al. (2018) suggested reaction time as an important biomarker of concussion. Laboratory camera-based motion capture data, while reliable, is not a realistic tool to use outside of a laboratory …

Understanding Parkinson’S Disease Through Gait Initiation And Center Of Pressure, Mira Ananthanarayanan, Kiara Salceda, Michael Shiraishi, Rahul Soangra

Student Scholar Symposium Abstracts and Posters

Parkinson's disease is a neurological disorder that causes tremors and freezing of gait in diagnosed patients. Freezing of gait can be difficult to identify and intervene without laboratory based instruments data collection. Force plates have been proven to show viable results in identifying gait events such as heel contact and toe off. The complete gait cycle consists of a right-heel strike, right heel-to-toe shift, simultaneous right-toe off/left heel strike, left heel-to-toe shift, and a simultaneous left-toe off/right heel strike. This study will investigate center of pressure trajectories when initiating gait between healthy and Parkinson's participants. It is predicted that the …

Identifying Voice-Based Digital Biomarkers Of Parkinson's Disease, Rachelle Beshay, Madison Gill, Michael Shiraishi, Rahul Soangra

Student Scholar Symposium Abstracts and Posters

Introduction: Parkinson's disease is a disorder in the central nervous system that causes tremors, abnormal gait and balance, and muscle rigidity due to loss of function in parts of the brain. Traditionally, Parkinson's is identified by the physical symptoms seen in a patient's gait and motor skills, but irregular speech patterns (hypokinetic dysarthria) is one of the first symptoms to be derived from the disease. Objective: The goal of this ongoing study is to use Mel Frequency Centrum Coefficients (MFCC), to diagnose Parkinson's in the early stages by identifying hypokinetic dysarthria. MFCC's process speech recognition patterns and produce …

Maintaining Physical Activity During Covid-19: The Influence Of Psychosocial Variables In Individuals With Back Pain, Heidi Stabbert

Student Scholar Symposium Abstracts and Posters

Stressor events, such as COVID-19, may trigger adaptive or maladaptive pain management strategies among individuals with persistent low back pain (LBP). Individuals with lower fear avoidance, depression and anxiety, and greater positive affect and quality of life may better maintain positive pain management strategies during stressor events. This study investigated psychosocial characteristics of individuals with LBP who demonstrated adaptive pain management strategies during COVID-19, indicated by maintenance of physical activity (PA). Individuals with persistent LBP (age 22.4 (3.4) years, n=25) from an existing longitudinal cohort participated. Participants completed a baseline survey prior to COVID-19 quantifying demographics, pain characteristics, the Physical …

How Degrees Of Freedom Affects Sense Of Agency, Akima Connelly, Jungsu Pak, Tian Lan, Uri Maoz

Student Scholar Symposium Abstracts and Posters

Can the rubber-hand illusion be extended to a moving robotic arm in different degrees of freedom (DOF), inducing sense of ownership & agency over the arm? We hypothesize that DOF closer to what humans possess will result in a stronger sense of ownership and agency.
