The Reliability and Validity of a Novel Clinical Test for Assessing Shoulder Rotation ROM in Collegiate Baseball Players: Functional Assessment of System Tension of the Shoulder (FAST-SHDR).

Background: Traditional methods to measure rotational passive range of motion (PROM) in the throwing shoulder do not reflect the complexity of the throwing motion. Therefore, a sport specific shoulder rotation PROM test (FAST-SHDR) was developed and compared to traditional standard methods to measure shoulder internal and external rotational PROM in the throwing shoulder.

Purpose: The aim of this study was to determine the intra-rater reliability of the FAST-SHDR test in young, healthy, male Division 1 baseball players.

Do ACL Injury Risk Reduction Exercises Reflect Common Injury Mechanisms? A Scoping Review of Injury Prevention Programs.

Context: Anterior cruciate ligament (ACL) injury risk reduction programs have become increasingly popular. As ACL injuries continue to reflect high incidence rates, the continued optimization of current risk reduction programs, and the exercises contained within them, is warranted. The exercises must evolve to align with new etiology data, but there is concern that the exercises do not fully reflect the complexity of ACL injury mechanisms.

Do currently prescribed exercises reflect contributing pathomechanics associated with femoroacetabular impingement syndrome? A scoping review.

Objective: Research reports limited, mixed evidence on the effectiveness of physiotherapy management in the treatment of femoroacetabular impingement (FAI) syndrome. The purpose of this review was to (1) identify what therapeutic exercises are being utilized in the non-surgical management of patients with FAI syndrome; (2) map the extent to which reported exercises reflect contributory pathomechanics associated with FAI syndrome.

Design: Scoping Review.

FRAMEWORK FOR OPTIMIZING ACL REHABILITATION UTILIZING A GLOBAL SYSTEMS APPROACH.

Unlabelled: Knee injuries such as ACL tears commonly occur and there is a high re-injury rate after primary ACL reconstruction with figures estimated at 25%-33%. Clinicians often use hip strengthening as a key component of knee rehabilitation. Evidence suggests that adopting a "regional" or "proximal" approach to rehabilitation can increase hip strength, but motor control often remains unchanged, particularly during more complex tasks such as running and jumping.

Jump load and landing patterns of collegiate female volleyball players during practice and competition.

Background: Overuse lower extremity injuries are common in women's court volleyball players and are likely due to the repetitive jumping and landing the sport requires. The purpose of this study was to quantify jump load during collegiate women's volleyball, describe the quantity of double-leg (DL) to single-leg (SL) landing strategies, and compare loads and landing strategies between games and practices.

Methods: Fourteen collegiate Division-1 women's court volleyball players participated in the study.

Rethinking Dynamic Knee Valgus and Its Relation to Knee Injury: Normal Movement Requiring Control, Not Avoidance.

The risk of knee injury in sport may be related to deviations in lower-limb alignment. An example of biomechanical deviation is dynamic knee valgus, considered by many to be one of the most important predictors of serious knee injury; however, the predictive validity of commonly used screening tests for dynamic knee valgus has recently been questioned. In this Viewpoint, the authors argue that assessing the risk of knee injury is complex and endeavor to present pelvic pronation and system tension as a 3-D construct to consider during physical assessments and exercise design, and to recognize dynamic knee valgus as a normal and necessary response to ground reaction forces.

Rehabilitation Exercises Reduce Reinjury Post Ankle Sprain, But the Content and Parameters of an Optimal Exercise Program Have Yet to Be Established: A Systematic Review and Meta-analysis.

Objectives: To determine if exercise-based rehabilitation reduces reinjury following acute ankle sprain. Our secondary objective was to assess if rehabilitation efficacy varies according to exercise content and training volume.

Data Sources: The following electronic databases were searched: EMBASE, MEDLINE, the Cochrane Central Register of Controlled Trials, and Physiotherapy Evidence Database (PEDro).

Activity Demands During Multi-Directional Team Sports: A Systematic Review.

Background: Late-stage rehabilitation programs often incorporate 'sport-specific' demands, but may not optimally simulate the in-game volume or intensity of such activities as sprinting, cutting, jumping, and lateral movement.

Objective: The aim of this review was to characterize, quantify, and compare straight-line running and multi-directional demands during sport competition.

Data Sources: A systematic review of PubMed, CINAHL, SPORTDiscus, and Cochrane Central Register of Controlled Trials databases was conducted.

Exercise prescription for overhead athletes with shoulder pathology: a systematic review with best evidence synthesis.

Objective: To produce a best evidence synthesis of exercise prescription used when treating shoulder pathology in the overhead athlete.

Design: A systematic review of exercises used in overhead athletes including case studies and clinical commentaries.

Data Sources: MEDLINE, PubMed, SPORTDiscus and CINAHL from database inception through July 8, 2016.

Association of Lower Quarter Y-Balance Test with lower extremity injury in NCAA Division 1 athletes: an independent validation study.

Objectives: To determine if the Lower Quarter Y-Balance Test (LQYBT) is predictive of lower extremity injury in NCAA Division 1 athletes.

Design: Prospective cohort, therapy.

Participants: One hundred eighty-nine NCAA Division 1 athletes participated in the study and underwent a preparticipation screen that included the LQYBT.

Non-operative management of femoroacetabular impingement: A prospective, randomized controlled clinical trial pilot study.

Objectives: To determine the efficacy of physical therapy on pain and physical function in patients with femoroacetabular impingement.

Design: Randomized, participant- and assessor blinded controlled trial pilot study.

Methods: This trial was registered at ClinicalTrials.

An evidence-based review of hip-focused neuromuscular exercise interventions to address dynamic lower extremity valgus.

Deficits in proximal hip strength or neuromuscular control may lead to dynamic lower extremity valgus. Measures of dynamic lower extremity valgus have been previously shown to relate to increased risk of several knee pathologies, specifically anterior cruciate ligament ruptures and patellofemoral pain. Therefore, hip-focused interventions have gained considerable attention and been successful in addressing these knee pathologies.
