Article Abstract
Context: Sports-related concussions are commonly occurring injuries as a result of sports and recreation that may cause alterations in brain functioning. It is important to be able to evaluate the impact of these injuries on function to manage the injury recovery and ensure recovery. Recent literature suggests the use of objective evaluation strategies in a multifaceted approach to evaluate and manage these injuries. It is important to understand the relationships between the assessments and how best to utilize each assessment. The purpose of this study was to investigate if relationships exist between measures of vestibular function at baseline in assessments that may be used following sports-related concussions. Additionally, a secondary purpose was to determine if self-reported symptoms were related to performance on the assessments. This study aimed to identify if these assessments measured independent functions of the vestibulo-ocular reflex or if some redundancy existed among the assessment strategies.
Design: A cross-sectional study design was used in a cohort of collegiate athletes ages 18-24.
Methods: Participants completed demographics questionnaires, the Post-Concussion Symptom Scale, Gaze Stabilization Test, and Concussion Balance Test. Spearman rho correlations were used to examine the relationships between the measures.
Results: One hundred and thirty-five collegiate athletes (82 males and 53 females) were included, representative of 3 sports (cheerleading, soccer, and football) with a mean age of 19.77 (1.42) years old. There were weak to moderate, significant relationships between measures of Gaze Stabilization Test and Concussion Balance Test errors (r = .20-.31, P = .001-.03).
Conclusions: The direction of these relationships indicated that greater Concussion Balance Test errors were associated with greater Gaze Stabilization Test performance. These relationships may be attributed to the difficulty created by the foam conditions and the integration of more complex sensory tasks required to maintain balance during the more difficult conditions.

Measurable neuromotor control deficits during functional task performance could provide objective criteria to aid in concussion diagnosis. However, many tools which measure these constructs are unidimensional and not clinically feasible. The purpose of this study was to assess the classification accuracy of a machine learning model using features measured by a clinically feasible movement-based assessment system (Mizzou Point-of-care Assessment System (MPASS) between athletes with and without concussion.

Background: Race associated differences and disparities in test scores, such as on neuropsychological measures, can complicate the interpretation of these test scores in student athletes following a concussion. It is unknown if there are race associated differences on the Sway Medical System, a battery that includes balance and cognitive tests for use in concussion management.
Purpose: To determine if there are race-associated differences in Sway Medical System balance and cognitive module scores among athletes undergoing preseason baseline testing.
Objective: Traumatic brain injury affects 1.5 million people per year in the United States, with the majority classified as mild (mTBI). While many immediate symptoms are limited to the short-term, some patients experience long-term daily impairments in function and quality of life.

Background: Sport-related concussion (SRC) can be associated with glymphatic system dysfunction that may be assessed using the diffusion tensor imaging along the perivascular space (DTI-ALPS) index. Here, DTI-ALPS between adolescent athletes within 10 days of SRC and after recovery with control adolescents are compared, and associations between the DTI-ALPS and clinical outcomes are explored.

Assessing Brain Neurophysiology in COVID-19 Patients With Prolonged Cognitive Fatigue: A Comparison With Persistent Post-concussion Symptoms.

Introduction: Brain fog and cognitive dysfunction are frequently reported in post-viral fatigue syndromes such as long COVID, yet these symptoms remain challenging to quantify objectively. Notably, many individuals with long COVID describe clinical features that overlap with those observed in patients with persistent post-concussion symptoms (PPCS), including cognitive fatigue, exertional intolerance, mood disturbances, visual and balance problems, headaches, and neck pain. Emerging evidence suggests that PPCS is associated with distinct electrophysiological abnormalities, including altered functional connectivity (measured by electroencephalography (EEG) coherence), spatial changes in EEG amplitude distribution (notably increased frontal alpha and left-right asymmetry), and reduced cognitive evoked potentials (e.
