Objective: To examine the influence of age, sex, attention-deficit hyperactivity disorder (ADHD) status, previous history of concussion, and days since injury on postconcussion postural control assessment in adolescents who have suffered a concussion.

Design: Prospective cohort study.

Setting: Hospital-based outpatient clinic.

Aerobic Exercise for Adolescents With Prolonged Symptoms After Mild Traumatic Brain Injury: An Exploratory Randomized Clinical Trial.

Objective: To describe the methodology and report primary outcomes of an exploratory randomized clinical trial (RCT) of aerobic training for management of prolonged symptoms after a mild traumatic brain injury (mTBI) in adolescents.

Setting: Outpatient research setting.

Participants: Thirty adolescents between the ages of 12 and 17 years who sustained a mTBI and had between 4 and 16 weeks of persistent symptoms.

The Back Squat Part 2: Targeted Training Techniques to Correct Functional Deficits and Technical Factors that Limit Performance.

The back squat is a well-researched and widely used exercise to enhance fundamental movement competency that creates a foundation for optimal mechanical strategies during a broad range of activities. The primary commentary introduced the Back Squat Assessment (BSA): a criterion based assessment of the back squat that delineates 30 potentially observable functional deficits. This follow-up commentary provides a targeted system of training cues and exercises to supplement the BSA to guide corrective intervention.

PHYSICAL THERAPY INTERVENTION STRATEGIES FOR PATIENTS WITH PROLONGED MILD TRAUMATIC BRAIN INJURY SYMPTOMS: A CASE SERIES.

Background And Purpose: Although most patients recover from a mild traumatic brain injury (mTBI) within 7-14 days, 10-30% of people will experience prolonged mTBI symptoms. Currently, there are no standardized treatment protocols to guide physical therapy interventions for this population. The purpose of this case series was to describe the unique, multimodal evaluation and treatment approaches for each of the patients with post-concussion syndrome (PCS).

Postconcussion Postural Sway Variability Changes in Youth: The Benefit of Structural Variability Analyses.

Purpose: The purpose of this study was to evaluate the utility of postural sway variability as a potential assessment to detect altered postural sway in youth with symptoms related to a concussion.

Methods: Forty participants (20 who were healthy and 20 who were injured) aged 10 to 16 years were assessed using the Balance Error Scoring System (BESS) and postural sway variability analyses applied to center-of-pressure data captured using a force plate.

Results: Significant differences were observed between the 2 groups for postural sway variability metrics but not for the BESS.

The back squat: A proposed assessment of functional deficits and technical factors that limit performance.

Fundamental movement competency is essential for participation in physical activity and for mitigating the risk of injury, which are both key elements of health throughout life. The squat movement pattern is arguably one of the most primal and critical fundamental movements necessary to improve sport performance, to reduce injury risk and to support lifelong physical activity. Based on current evidence, this first (1 of 2) report deconstructs the technical performance of the back squat as a foundation training exercise and presents a novel dynamic screening tool that incorporates identification techniques for functional deficits that limit squat performance and injury resilience.

The utility of the balance error scoring system for mild brain injury assessments in children and adolescents.

The Balance Error Scoring System (BESS) is widely recognized as an acceptable assessment of postural control for adult patients following a mild traumatic brain injury (mTBI) or concussion. However, the measurement properties of the BESS as a post-mTBI assessment test for younger patients are not well understood. The purpose of this study was to evaluate the utility of the BESS as a post-mTBI assessment test for children and adolescents aged 8 to 18 years through 2 investigations: (1) a retrospective medical records review of the relationship among age, BESS scores, and other common post-mTBI assessment tests; and (2) a prospective study comparing BESS scores for a cohort of children with a recent mTBI and BESS scores for a cohort of matched healthy peers.

Reduced hip strength is associated with increased hip motion during running in young adult and adolescent male long-distance runners.

Study Design: Controlled laboratory study.

Background And Purpose: Anterior knee pain is one of the most common running symptoms reported in the literature. While the exact etiology is unknown, a lack of hip strength is suggested to contribute to abnormal running mechanics.

Test-retest consistency of a postural sway assessment protocol for adolescent athletes measured with a force plate.

Purpose/background: Postural control assessments can provide a powerful means of detecting concussion-related neurophysiological abnormalities and are considered an important part of the concussion management processes. Studies with college athletes indicate that postural sway analyzed using complexity metrics may provide a sensitive and novel way to detect post-concussion postural control impairments. The purpose of this study was to determine if a postural sway assessment protocol (PSAP) measured using a force plate system can serve as a reliable assessment tool for adolescent athletes.

Relationship between hip strength and trunk motion in college cross-country runners.

Purpose: Hip strength may directly relate to abnormal running mechanics and contribute to the high incidence of overuse injuries in distance runners. The purpose of this study was to determine the relationship between hip isokinetic strength and thorax and pelvic motion during treadmill running.

Methods: Isokinetic hip strength and treadmill running kinematics were collected on 24 collegiate cross-country runners (14 males and 10 females).
