The Effect of Exercise on a Novel Dual-Task Assessment for Sport Concussion.

Purpose: This study aimed to determine the effect of exercise on cognitive and motor performance and the subsequent test-retest reliability of a novel dual-task (DT) assessment in nonconcussed college students.

Methods: Sixty nonconcussed college students (53.3% female) with an average age (±SD) of 20.

Kinesiophobia Is Related to Acute Musculoskeletal Injury Incidence Following Concussion.

Context: Athletes with a history of sport concussion (SC) have an increased risk of musculoskeletal injury (MSK); however, the underlying mechanisms have yet to be determined. The purpose of our study was to evaluate kinesiophobia in college athletes with or without a time-loss MSK within 180 days of unrestricted return to play following a SC.

Design: This was a retrospective cohort study within a sports medicine facility.

The Clinical Utility of the Child SCAT5 for Acute Concussion Assessment.

Background: The Child Sport Concussion Assessment Tool 5th Edition (Child SCAT5) was developed to evaluate children between 5 and 12 years of age for a suspected concussion. However, limited empirical evidence exists demonstrating the value of the Child SCAT5 for acute concussion assessment. Therefore, the purpose of our study was to examine differences and assess the diagnostic properties of Child SCAT5 scores among concussed and non-concussed middle school children on the same day as a suspected concussion.

Footwear Type and Testing Environment Do Not Affect Baseline Modified Balance Error Scoring System Performance Among Middle School Athletes.

Context: Limited evidence exists to demonstrate the effect of extrinsic factors, such as footwear worn or the testing environment, on performance of the modified balance error scoring system (mBESS) in the middle school age (10-14 y) population. Therefore, the purpose of our study was to investigate the effect of footwear types and testing environments on performance of the mBESS by middle school athletes.

Design: Cross-sectional.

Reevaluating clinical assessment outcomes after unrestricted return to play following sport-related concussion.

Primary Objective: The objective of this study was to examine neurocognition, postural control, and symptomology at multiple timepoints following concussion. We hypothesized that collegiate athletes would perform similar to or better than their baseline in terms of each outcome at both timepoints.

Research Design: This was a retrospective study of 71 collegiate athletes (18.

The Effect of Muscle Activation on Head Kinematics During Non-injurious Head Impacts in Human Subjects.

In this study, twenty volunteers were subjected to three, non-injurious lateral head impacts delivered by a 3.7 kg padded impactor at 2 m/s at varying levels of muscle activation (passive, co-contraction, and unilateral contraction). Electromyography was used to quantify muscle activation conditions, and resulting head kinematics were recorded using a custom-fit instrumented mouthpiece.

If Not Now, When? An Absence of Neurocognitive and Postural Stability Deficits in Collegiate Athletes with One or More Concussions.

A history of concussion has been associated with decreased neurocognitive function and postural control. The purpose of our study was to compare neurocognitive function and postural control in collegiate athletes with and without varying histories of concussion. Collegiate athletes were divided into groups based on 0 ( = 129), 1 ( = 91), 2 ( = 52), and 3+ ( = 34) prior concussions.

Institutionally Based ImPACT Test® Normative Values May Differ from Manufacturer-Provided Normative Values.

Objective: The necessity for pre-injury baseline computerized neurocognitive assessments versus comparing post-concussion outcomes to manufacturer-provided normative data is unclear. Manufacturer-provided norms may not be equivalent to institution-specific norms, which poses risks for misclassifying the presence of impairment when comparing individual post-concussion performance to manufacturer-provided norms. The objective of this cohort study was to compare institutionally derived normative data to manufacturer-provided normative values provided by ImPACT® Applications, Incorporated.
