The Effect of Stride Length and Lateral Pelvic Tilt on Elbow Torque in Youth Baseball Pitchers.

High elbow torque during a pitch may contribute to injury risk. Our objective was to determine the pitch mechanics associated with elbow varus torque in youth baseball pitchers. Eighteen male youth pitchers (age = 15.

Single-Task and Dual-Task Gait Among Collegiate Athletes of Different Sport Classifications: Implications for Concussion Management.

Gait impairments have been documented following sport-related concussion. Whether preexisting gait pattern differences exist among athletes who participate in different sport classifications, however, remains unclear. Dual-task gait examinations probe the simultaneous performance of everyday tasks (ie, walking and thinking), and can quantify gait performance using inertial sensors.

The Effect of Prior Concussion History on Dual-Task Gait following a Concussion.

Sustaining repeated concussions has been associated with worse outcomes after additional injuries. This effect has been identified using symptom inventories and neurocognitive tests; however, few investigations have examined how a prior concussion history affects gait soon after a subsequent concussion. We examined the gait characteristics of athletes with no documented concussion history (n = 31), athletes recovering from their first lifetime concussion (n = 15), and athletes recovering from their second or greater lifetime concussion (n = 22).

Body Mass Index and Menstrual Patterns in Dancers.

Questionnaires were distributed to investigate body mass index (BMI) and menstrual patterns in female dancers aged 12 to 17 years. The study cohort consisted of 105 dancers, mean age 14.8 ± 1.

Etiology and body area of injuries in young female dancers presenting to sports medicine clinic: A comparison by age group.

Introduction: Improving knowledge regarding injuries sustained by pediatric dancers is important in order to better understand injury risk. The aim of this study is to analyze dance injury etiology and body area by age in a cohort of young female dancers presenting to a pediatric sports/dance medicine clinic.

Methods: The cross-sectional epidemiological study of a 5% probability sample of dancers evaluated between 1/1/2000 and 12/31/2009 with a musculoskeletal injury requiring physician evaluation.
