Online Decoding Of Rat Self-Paced Locomotion Speed From Eeg Using Recurrent Neural Networks, Alejandro De Miguel, Nelson Totah, Uri Maoz

Psychology Faculty Articles and Research

Objective. Accurate and reliable neural decoding of locomotion holds promise for advancing clinical applications such as rehabilitation and prosthetic control, as well as for understanding neural correlates of action. Recent studies have demonstrated successful decoding of locomotion kinematics across species in motorized treadmill settings. However, efforts to decode locomotion speed directly and continuously in more natural contexts—where pace is self-selected rather than externally imposed—are scarce, and those that exist generally achieve only modest accuracy and require intracranial implants. Here, we aim to decode self-paced locomotion speed non-invasively and continuously using cortex-wide electroencephalography (EEG) recordings from rats. Approach. We introduce an …

Communication Sciences and Disorders Faculty Articles and Research

Effective rehabilitation tools are essential for improving language outcomes in chronic aphasia. Speech entrainment is a behavioral treatment that has shown promise in enhancing speech output in nonfluent aphasia, potentially by acting as an external mechanism to synchronize anterior and posterior language regions in the left hemisphere. Transcranial alternating current stimulation has been hypothesized to enhance functional connectivity between brain regions by amplifying endogenous oscillations. This proof-of-concept study explored whether high-definition tACS (HD-tACS) could improve speech fluency in nonfluent aphasia when paired with speech entrainment. In a double-blind, pseudorandomized study, 1 mA of HD-tACS at 7 Hz was applied to …

Dual-Task Effects On Spatiotemporal, Kinematic, And Kinetic Parameters And Their Variability During Running, Hsiang-Ling Teng, Jo Armour Smith, Will F.W. Wu

Physical Therapy Faculty Articles and Research

Background

Running in real-world environments often requires using cognitive resources simultaneously with the motor task (dual tasking, DT). Limited existing evidence suggests that DT reduces running speed. Movement variability is essential for a healthy, adaptable motor system. DT has been shown to affect movement variability during walking. Nonetheless, it remains unclear how DT affects spatiotemporal, kinematic, and kinetic parameters and their variability during running.

Research question

Does DT affect spatiotemporal, kinematic, and kinetic measures and their variability during running? Does running speed influence DT effects?

Methods

Thirty-one asymptomatic runners participated in this cross-sectional study. Three-dimensional running biomechanics were recorded while …

Evaluating The Effect Of Ethnicity And Amyloid On Gait Speed In The Healthy Aging Brain Study-Health Disparities Study, Alexandra M. Reed, Andrew Hooyman, Edward Ofori, Sydney Y. Schaefer

Physical Therapy Faculty Articles and Research

Background

Many novel Alzheimer's disease (AD) biomarkers have been studied in non-Hispanic White populations, despite Hispanic/Latino adults being 1.5 times more likely to develop AD and receiving a later diagnosis. Equitable, accessible assessments are needed to identify individuals at risk earlier. While cognitive screening monitors early AD signs, neuropsychological tests are often inequitable across ethnicity, race, and other social determinants of health. However, we have shown that performance-based motor assessments may be less susceptible to demographic factors than memory tests, and may be more equitable for screening older adults. Gait speed has been linked to elevated amyloid in non-Hispanic White …

Physical Therapy Faculty Articles and Research

Maladaptive plasticity in the brain may contribute to chronic low back pain (LBP) and underlie the altered postural control of the lumbopelvic musculature that is evident in some individuals with LBP. We recently described an MRI-compatible leg-raise paradigm to measure brain activity associated with lumbopelvic postural control. The objective of this study was to compare brain function in young adults with and without a history of LBP and to determine relationships between brain function, pain, and postural control characteristics. We recruited 55 participants with a history of LBP, who were asymptomatic when studied, and 30 healthy controls. Postural control during …

Information About Task Duration Influences Energetic Cost During Split-Belt Adaptation And Retention Of Walking Patterns Post-Adaptation, Samantha N. Jeffcoat, Adrian Aragon, Andrian Kuch, Shawn Farrokhi, Andrew Hooyman, Russell Johnson, Natalia Sanchez

Physical Therapy Faculty Articles and Research

Studies of locomotor adaptation have shown that adaptation can occur in short bouts and can continue for long bouts or across days. Information about task duration might influence the adaptation of gait features, given that task duration influences the time available to explore and adapt the aspects of gait that reduce energy cost. We hypothesized that information about task duration and frequency of updates influences adaptation to split-belt walking based on two competing mechanisms: individuals anticipating a prolonged adaptation period may either (1) extend exploration of energetically suboptimal gait patterns, or (2) adapt toward a more energy-efficient pattern earlier to …

The Differential Effects Of Fast Walking Speed On Muscle Coactivation In The Paretic And Non-Paretic Extremities Post-Stroke, Natalia Sánchez, Andrian Kuch, Samantha N. Jeffcoat, Andrew Hooyman, Aria Haver-Hill, Christina K. Holl, Kristan A. Leech

This study examines the combined effects of green noise and texting on gait to understand how multitasking and auditory stimuli affect walking stability. Green noise, associated with relaxation, was the environmental stimulus; texting the cognitive distractor. We hypothesized texting would reduce cadence and stride length, with green noise either stabilizing or disrupting gait. Ten participants walked on a treadmill under five conditions: normal walking (NW), no texting/sound (WNTNS), sound only (WNTS), texting only (WTNS), and texting with sound (WTS). Gait parameters—step length, step width, single support time, and terminal double support time—were analyzed. Step length decreased in WNTS (p …

Identification Of Subtypes Of Post-Stroke And Neurotypical Gait Behaviors Using Neural Network Analysis Of Gait Cycle Kinematics, Andrian Kuch, Nicolas Schweighofer, James M. Finley, Alison Mckenzie, Yuxin Wen, Natalia Sánchez

Physical Therapy Faculty Articles and Research

Gait impairment post-stroke is highly heterogeneous. Prior studies classified heterogeneous gait patterns into subgroups using peak kinematics, kinetics, or spatiotemporal variables. A limitation of this approach is the need to select discrete features in the gait cycle. Using continuous gait cycle data, we accounted for differences in magnitude and timing of kinematics. Here, we propose a machine-learning pipeline combining supervised and unsupervised learning. We first trained a Convolutional Neural Network and a Temporal Convolutional Network to extract features that distinguish impaired from neurotypical gait. Then, we used unsupervised time-series k-means and Gaussian Mixture Models to identify gait clusters. We tested …

Variance In Heart Rate Variability Between Healthy And Concussed Individuals, Sebastian Herrera Vargas, Joonsuk Choi

Student Scholar Symposium Abstracts and Posters

Heart-Rate Variability (HRV) is the interval between each individual heartbeat, from p-wave to p-wave on an electrocardiogram (ECG). In general, a high HRV indicates that a person has a healthy heart with effective stress management skills. This value means that one branch of the nervous system is not overpowering the other, sympathetic vs parasympathetic–for example. Generally, HRV is related to vagal tone, the ability for your body to activate the parasympathetic system and relax when imminent danger is not present. However, when someone is concussed, the entirety of their autonomic regulation can be affected such that their HRV is altered. …

Effects Of Simultaneous Smartphone Texting And Auditory Stimulation On Gait, Sebastian Herrera Vargas

Student Scholar Symposium Abstracts and Posters

More often than not, pedestrians around busy college campuses, business parks, and shopping malls are seen walking while using their phones and listening to music or having earphones in. Activities on pedestrians’ phones that captivate them more and require higher cognitive processing demonstrated a higher detriment to their gait kinematics than less cognitively complicated activities (Brennan and Preloff, 2021). This study aims to establish whether or not gait parameters are affected by walking while engaging in cognitively demanding activities such as texting and listening to green noise. Green noise is a deviation from white noise, which amplifies the mid-range frequencies …

Gait adaptation during bipedal walking allows people to adjust their walking patterns to maintain balance, avoid obstacles and avoid injury. Adaptation involves complex processes that function to maintain stability and reduce energy expenditure. However, the processes that influence walking patterns during different points in the adaptation period remain to be investigated. We assessed split-belt adaptation in 17 young adults aged 19–35. We also assessed individual aerobic capacity to understand how aerobic capacity influences adaptation. We analyzed step lengths, step length asymmetry (SLA), mediolateral margins of stability, positive, negative and net mechanical work rates, as well as metabolic rate during adaptation. …

Background

In the United States, there are over seven million stroke survivors, with many facing gait impairments due to foot drop. This restricts their community ambulation and hinders functional independence, leading to several long-term health complications. Despite the best available physical therapy, gait function is incompletely recovered, and this occurs mainly during the acute phase post-stroke. Therapeutic options are limited currently. Novel therapies based on neurobiological principles have the potential to lead to long-term functional improvements. The Brain-Computer Interface (BCI) controlled Functional Electrical Stimulation (FES) system is one such strategy. It is based on Hebbian principles and has shown promise …

Evaluating Visual Dependence In Postural Stability Using Smartphone And Stroboscopic Glasses, Brent A. Harper, Michael Shiraishi, Rahul Soangra
