Introduction: Sport and tactical populations are often impacted by musculoskeletal injury. Many publications have highlighted that risk is correlated with multiple variables. There do not appear to be existing studies that have evaluated a predetermined combination of risk factors that provide a pragmatic model for application in tactical and/or sports settings.

Background: Elite female athletes who successfully return to sport after anterior cruciate ligament reconstruction (ACLR) represent a high-risk group for secondary injury. Little is known about how the functional profile of these athletes compares to their teammates who have not sustained ACL injuries.

Purpose: To compare elite collegiate female athletes who were able to successfully return to sport for at least one season following ACLR to their teammates with no history of ACLR with regard to self-reported knee function, kinetics, and kinematics during a double limb jump-landing task.

Background: Injury incidence for physically active populations with a high volume of physical load can exceed 79%. There is little existing research focused on timing of injury and how that timing differs based on certain risk factors.

Purpose/hypothesis: The purpose of this study was to report both the incidence and timing of lower extremity injuries during cadet basic training.

Objectives: The purpose of this article was to determine if differences in kinematic and kinetic variables observed in a double-leg screen carried over to a single-leg task.

Design: We used a case-control design with grouping based on performance during a double-leg jump landing.

Setting: All participants were selected from a large university setting and testing was performed in a biomechanics laboratory.

"Cox proportional hazards regression models with frailty found no difference in injured vs. unin-jured players with week-to-week changes of < 20, 20-60, and > 60%, controlling for scapular con-trol, isometric rotational and abduction strength, and shoulder range of motion (p value ranges 0.09-0.

Background: The relationship between training load and musculoskeletal injury is a rapidly advancing area of research in need of an updated systematic review.

Objective: This systematic review examined the evidence for the relationship between training load and musculoskeletal injury risk in athlete, military, and first responder (i.e.

Stress Fracture of the Sacrum.

J Orthop Sports Phys Ther

November 2015

A physical therapist evaluated a 25-year-old male military trainee, who reported 1 week of left hip pain exacerbated by running and sitting cross-legged. At follow-up, the patient reported unchanged hip pain and new left knee pain. Due to potential for multifocal stress injuries outside the visual field of a single MRI, bone scan and single-photon emission computerized tomography were chosen as imaging modalities.

Purpose: In 1995, the American Board of Internal Medicine (ABIM) formalized an integrated residency curriculum including both clinical and research training (the Research Pathway), designed to develop careers of physician-scientists. Individuals who completed Pathway training between 1995 and 2007 were surveyed to determine the extent to which graduates established research-oriented careers.

Method: In 2012, the authors used a Web-based, 56-question, multiple-choice electronic survey of 813 participants in Research Pathway programs who completed their residency training between the years of 1995 and 2007.
