Baseline Symptoms and Neurocognitive Performance across Collision, Contact, and Noncontact Female High School Athletes.

Purpose: Our purpose was to represent a rare cohort of female collision sport athletes and investigate the association between sport type (collision, contact, and noncontact), symptoms, and performance on baseline neurocognitive assessments.

Methods: We conducted a cross-sectional study using baseline computerized neurocognitive scores (Immediate Postconcussion Assessment and Cognitive Testing [ImPACT]) of 75,128 female high school student-athletes (age, 15.27 ± 1.

Concussion Symptoms and Neurocognitive Performance of Children and Adolescents on Antidepressants.

Introduction/purpose: There is a well-established association between preexisting depression/anxiety and greater postconcussion symptom burden, but the potential impact of antidepressant medications has not been fully explored. The primary objective of this study was to compare preinjury/baseline and postinjury concussion symptom scores and neurocognitive performance of athletes on antidepressant medications, both with healthy controls and with those with depression/anxiety not on antidepressants.

Methods: This is a cross-sectional study using data collected from 49,270 junior and high school athletes from computerized neurocognitive assessments (Immediate Post-Concussion Assessment and Cognitive Test [ImPACT]) administered between 2009 and 2018 held by the Massachusetts Concussion Management Coalition.

Associations between anterior knee pain and 2-year patellofemoral cartilage worsening: The MOST study.

Objective: Anterior knee pain (AKP) is associated with patellofemoral osteoarthritis (PFOA), but longitudinal studies are lacking. If AKP precedes PFOA, it may create an opportunity to identify and intervene earlier in the disease process. The purpose of this study was to examine the longitudinal relation of AKP to worsening patellofemoral (PF) cartilage over two years.

Association of tibial acceleration during walking to pain and impact loading in adults with knee osteoarthritis.

Background: Higher impact loading during walking is implicated in the pathogenesis of knee osteoarthritis. Accelerometry enables the measurement of peak tibial acceleration outside the laboratory. We characterized the relations of peak tibial acceleration to knee pain and impact loading during walking in adults with knee osteoarthritis.

Inter-joint coordination variability is associated with pain severity and joint loading in persons with knee osteoarthritis.

As the lower extremity is a linked-joint system, the contribution of movements at the hip and ankle, in addition to the knee, to gait patterns should be considered for persons with knee osteoarthritis (OA). However, the relationships of joint coordination variability to OA symptoms, particularly knee pain, and joint loading is unknown. The purpose of this study was to determine the relationship of joint coordination variability to knee pain severity and joint loading in persons with knee OA.

Association Between Collision Sport Career Duration and Gait Performance in Male Collegiate Student-Athletes.

Background: Investigations of estimated age of first exposure to repetitive head impacts from collision and contact sports have shown no associations with neurocognitive or neurobehavioral function at the collegiate level, but the effect of career duration may be a more comprehensive factor. Understanding whether longer career duration influences gait performance would provide insights into potential neurological impairment.

Purpose: To examine the relationship between career duration of collision sports and single/dual-task gait performance in collegiate student-athletes.

Neurocognitive functioning and symptoms across levels of collision and contact in male high school athletes.

Objective: We sought to determine whether male collision sport athletes perform worse on computerised neurocognitive assessments and report higher symptom burdens than athletes in contact (but not collision) sports and athletes in non-contact sports.

Methods: This cross-sectional study used data collected by the Massachusetts Concussion Management Coalition on high school boys who underwent computerised neurocognitive testing between 2009 and 2018. We divided sports participation in three different sport types: (1) collision, (2) contact, non-collision and (3) non-contact.

Ultrasound Observation of Hip Translational Motion in Adolescent Dancers.

Hip microinstability, characterized by supraphysiologic movement of the femoroacetabular joint, has recently been recognized as a clinically relevant pathology. The potentially detrimental effects of its presence on joint health make identifying microinstability important; however, due to its multifaceted nature, screening for microinstability presents challenges. Musculoskeletal ultrasound offers an opportunity to visualize the arthrokinematics of the femoroacetabular joint on dynamic evaluation.

Associations Between Neurochemistry and Gait Performance Following Concussion in Collegiate Athletes.

Objective: To evaluate the strength of associations between single-task and dual-task gait measures and posterior cingulate gyrus (PCG) neurochemicals in acutely concussed collegiate athletes.

Setting: Participants were recruited from an NCAA Division 1 University.

Participants: Nineteen collegiate athletes acutely (<4 days) following sports-related concussion.

No differences in tandem gait performance between male and female athletes acutely post-concussion.

Objectives: To test whether 1) concussed athletes demonstrate slower tandem gait times compared to controls and 2) concussed female athletes display greater post-injury deficits than males.

Design: Prospective longitudinal METHOD: Fifty concussed collegiate student-athletes (32% female, age=20.18±1.

Dual-Task Gait Recovery after Concussion among Female and Male Collegiate Athletes.

Purpose: Few studies have investigated recovery between sexes using objective outcome measures. Our purpose was to examine the independent association between biological sex and recovery of postconcussion gait among collegiate athletes.

Methods: We evaluated participants with a diagnosed concussion <7 d postinjury, and approximately 1.

Hallux sesamoid fractures in young athletes.

: To describe the evaluation, management and recovery time of hallux sesamoid fractures in young athletes.: A retrospective chart review was performed in a large academic teaching institution over a 5-year period (1/1/2010-12/31/2014). All patients with a sesamoid injury were initially included.
