Youth Soccer Heading Exposure and Its Effects on Clinical Outcome Measures.

Purposeful heading, in which players may use their heads to advance the ball in play, is a unique part of soccer. Clinical outcome measures used to aid in the diagnosis of a concussion have long been a cornerstone of the contemporary measurements associated with the short- and long-term effects of monitoring repetitive head impacts (RHI) and soccer heading exposure. The effects of RHI in the youth population are still unknown, therefore, the purpose of this study was to examine if heading exposure is predictive of changes in self-reported symptoms, neurocognitive functioning, gait, and balance in female youth soccer players over the course of one soccer season.

Quantitative Analysis of Ball-Head Impact Exposure in Youth Soccer Players.

Since the implementation of the US Soccer heading guidelines released in 2015, little to no research on ball-head impact exposure in the United States youth soccer population has been conducted. The purpose was to compare ball-head impact exposure across sex and age in youth soccer players over a weekend tournament. Ten male and female games for each age group (Under-12 [U12], U13, and U14) were video recorded at a weekend tournament for a total of 60 games.

Effects of Pre-Collegiate Sport Specialization on Cognitive, Postural, and Psychological Functions: Findings from the NCAA-DoD CARE Consortium.

Background: Early sport specialization has been associated with an increased risk of musculoskeletal injuries and unfavorable psychological outcomes; however, it is unknown whether sport specialization is associated with worse cognitive, postural, and psychological functions in first-year collegiate student-athletes.

Methods: First-year collegiate multisport (MA) and single-sport (SA) student-athletes were identified using a pre-collegiate sport experience questionnaire. The cognitive, postural, and psychological functions were assessed by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), Standardized Assessment of Concussion (SAC), Balance Error Scoring System (BESS), and Brief Symptom Inventory 18 (BSI-18).

Internal (Factorial) Validity of the ANAM using a Cohort of Woman High-School Soccer Players.

Introduction: Computerized neuropsychological testing is a cornerstone of sport-related concussion assessment. Female soccer players are at an increased risk for concussion as well as exposures to repetitive head impacts from heading a soccer ball. Our primary aim was to examine factorial validity of the Automated Neuropsychological Assessment Metrics (ANAM) neuropsychological test battery in computing the multiple neurocognitive constructs it purports to measure in a large cohort of interscholastic female soccer players.

Development of Composite Scores for the TBI-QOL.

Objective: To develop a set of composite scores that can be used for interpreting quality of life (QOL) after traumatic brain injury (TBI) using 9 of the patient-reported outcomes measures from the Traumatic Brain Injury Quality of Life (TBI-QOL) measurement system.

Design: Participants completed 20 item banks from the TBI-QOL as part of a larger assessment. Composite index scores were created with normalized transformation with nonlinear area conversion using scores from 9 of the banks, and are expressed in index score units, with higher composite scores indicating better functioning.

Postural Control Deficits After Repetitive Soccer Heading.

Objective: To determine the acute effects of repetitive soccer heading on postural control.

Design: Prospective study; participants were divided into 2 groups: a soccer heading group and a control group.

Setting: Biomechanics laboratory.

Sex and age differences in head acceleration during purposeful soccer heading.

Differences in head-neck segment mass, purposeful heading technique, and cervical strength and stiffness may contribute to differences in head accelerations across sex and age. The purpose of this study was to compare head acceleration across sex and age (youth [12-14 years old], high school and collegiate) during purposeful soccer heading. One-hundred soccer players (42 male, 58 female, 17.

Head and neck size and neck strength predict linear and rotational acceleration during purposeful soccer heading.

There is increasing societal concern about the long-term effects of repeated impacts from soccer heading, but there is little information about ways to reduce head impact severity. The purpose of this study was to identify factors that contribute to head acceleration during soccer heading. One-hundred soccer players completed 12 controlled soccer headers.

Evaluating Postural Control and Ankle Laxity Between Taping and High-Top Cleats in High School Football Players.

Context: Lateral ankle sprains are the most common injuries in high school sports. While ankle taping is a preferred method of external prophylactic support, its restrictive properties decline during exercise. The Under Armour Highlight cleat is marketed on the premise that it provides added support without the need for additional ankle taping.

Assessing performance, stability, and cleat comfort/support in collegiate club soccer players using prophylactic ankle taping and bracing.

Soccer athletes at all levels of play are keenly aware of their equipment needs including cleat wear, and want to be protected from injury but without impeding on-field performance. Ankle injury is a common disorder that is prevalent in the sport of soccer and recent improvements in ankle prophylaxis interventions have proven effective. The aim of this study was to determine if the use of elastic taping or a neoprene sleeve alters performance, stability, and cleat comfort/support in soccer players compared to wearing a soccer cleat without any external support.

Examining Neurocognitive Function in Previously Concussed Interscholastic Female Soccer Players.

Awareness of sport-related concussions in soccer has gained recent attention in the medical community. Interestingly, purposeful heading-a unique yet strategic and inherent part of soccer-involves repeated subconcussive blows to the head. We divided 210 female interscholastic soccer players into control (CON [never concussed]) and experimental (EXP [previously concussed]) groups.

Effect of guided relaxation and imagery on falls self-efficacy: a randomized controlled trial.

Objectives: To examine the effects of guided relaxation and imagery (GRI) on improvement in falls self-efficacy in older adults who report having a fear of falling.

Design: Randomized, controlled trial with allocation to GRI or guided relaxation with music of choice.

Setting: General community.

Subgroups of Adult Basic Education Learners with Different Profiles of Reading Skills.

The purpose of this study was to identify subgroups of adult basic education (ABE) learners with different profiles of skills in the core reading components of decoding, word recognition, spelling, fluency, and comprehension. The analysis uses factor scores of those 5 reading components from on a prior investigation of the reliability and construct validity of measures of reading component skills (MacArthur, Konold, Glutting, & Alamprese, 2010). In that investigation, confirmatory factor analysis found that a model with those 5 factors fit the data best and fit equally well for native and non-native English speakers.

The effect of guided relaxation and exercise imagery on self-reported leisure-time exercise behaviors in older adults.

The purpose of this study was to examine the effects of a 6-wk intervention that used guided relaxation and exercise imagery (GREI) to increase self-reported leisure-time exercise behavior among older adults. A total of 93 community-dwelling healthy older adults (age 70.38 ± 8.

Cluster analysis of symptoms among patients with upper extremity musculoskeletal disorders.

Introduction: Some musculoskeletal disorders of the upper extremity are not readily classified. The study objective was to determine if there were symptom patterns in self-identified repetitive strain injury (RSI) patients.

Methods: Members (n = 700) of the Dutch RSI Patients Association filled out a detailed symptom questionnaire.

Reading component skills of learners in adult basic education.

The purposes of this study were to investigate the reliability and construct validity of measures of reading component skills with a sample of adult basic education (ABE) learners, including both native and nonnative English speakers, and to describe the performance of those learners on the measures. Investigation of measures of reading components is needed because available measures were neither developed for nor normed on ABE populations or with nonnative speakers of English. The study included 486 students, 334 born or educated in the United States (native) and 152 not born or educated in the United States (nonnative) but who spoke English well enough to participate in English reading classes.

Impact of decision support in electronic medical records on lipid management in primary care.

Electronic decision-support tools may help to improve management of hyperlipidemia and other chronic diseases. This study examined the impact of lipid management tools integrated into an electronic medical record (EMR) in primary care practices. This randomized controlled trial was conducted in a national network of physicians who use an outpatient EMR.

Examining the stability of Automated Neuropsychological Assessment Metric (ANAM) baseline test scores.

Computerized neuropsychological (NP) testing has evolved into an important tool for clinicians in the assessment of sport-related concussions. The importance of having a reliable baseline test score for comparison post concussion is critical; yet, the stability of these baseline measurements has not been well established. The purpose of this study was to examine the consistency of the measurements derived from the Automated Neuropsychological Assessment Metric (ANAM) test battery over a series of repeated trials, in an attempt to determine at what point the test scores stabilized.

ADHD and method variance: a latent variable approach applied to a nationally representative sample of college freshmen.

This study employed a correlated trait-correlated method application of confirmatory factor analysis to disentangle trait and method variance from measures of attention-deficit/hyperactivity disorder obtained at the college level. The two trait factors were Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV ) Inattention and DSM-IV Hyperactivity-Impulsivity. The two source factors were self-reports and parent-reports.

Patterns of memory: a normative taxonomy of the Wide Range Assessment of Memory and Learning-Second Edition (WRAML-2).

Memory is arguably the most important function of cognition. When left undetected, memory impairments are linked to life long underachievement and negative social consequences. Given that the construct of memory is multidimensional, the current study examined patterns of multiple indicators associated with memory across individuals ranging in age from 5 to 85 years who had been administered the Wide Range Assessment of Memory and Learning-Second Edition (WRAML-2).

A retrospective study of the factors associated with hypercoagulability in the pediatric patients at a tertiary care children's hospital.

Objective: The objective of this study was to determine the risk factors of hypercoagulability in children. We explored the interaction of multiple risk factors with the incidence of thrombosis. Our hypothesis was that as the number of risk factors for thrombosis increased the actual incidence of thrombosis would also increase.

Examining the relationship between purposeful heading in soccer and computerized neuropsychological test performance.

The purpose of this study was to determine if a relationship exists between purposeful heading in soccer and neuropsychological test performance. Automated Neuropsychological Assessment Metrics throughput scores were derived on seven subset variables that measure a variety of neurocognitive abilities. Simple Spearman's rank correlations were calculated between headers per game (HPG) and the criterion variables.

Purposeful heading during a season does not influence cognitive function or balance in female soccer players.

Soccer participation, especially among females, is growing in popularity in the United States. Purposeful heading, an important soccer skill, has recently been scrutinized for safety reasons. The purpose of this study was to determine whether there was a relationship between purposeful heading and scores on cognitive function and balance in high school and collegiate female soccer players.
