OBJECTIVE: To present the case of a 15 year-old baseball player with Little League Shoulder (LLS) and describe how developmental changes in the angle of humeral retrotorsion (HRT) may contribute to the underlying pathology of this condition. DESIGN: Case report.

OBJECTIVE: To identify whether baseline differences in hip and knee isometric strength exist among female runners who sustained a running related injury (RRI) and those that remained injury-free during a 16-week formalized training program. DESIGN: Prospective Cohort. SETTING: Laboratory Setting. PARTICIPANTS: 54 healthy female recreational runners enrolled in a formalized training program for half or full marathon. At the conclusion of the program, 50 female runners (age: 39...

OBJECTIVES: To examine whether different vertical drop jump (VDJ) landing depth (small versus deep) and stance width (wide versus narrow) may alter movement biomechanics in female recreational athletes. The purpose was also to identify whether leg muscle strength is a predictive factor for knee control during a VDJ. DESIGN: Cross-sectional. SETTING: Biomechanics laboratory. PARTICIPANTS: Eighteen women aged between 18 and 30 years...

OBJECTIVE: To determine if adolescent athletes with a history of lateral ankle sprain(s) (LAS) displayed deficits on functional performance tests (FPTs) and if deficits on FPT were related to the number of previous LAS. DESIGN: Cross-sectional study. SETTING: Biomechanics Laboratory. PARTICIPANTS: The injured group (n = 24) had a history of ≥1 moderate-severe LAS. The uninjured group (n = 34) had no history of LAS...

There is a strong push for the inclusion of effect size indexes alongside the reporting of statistical analysis in academic journals. Nonparametric methods of analysis have generally been developed less than their parametric counterparts have, and are also generally less well known. Too often researchers use parametric statistics where nonparametric measures would be more appropriate. This holds true for nonparametric measures of effect size, where even when researchers use nonparametric statistics, some use parametric effect size measures to interpret the result...

OBJECTIVE: The flexor carpi ulnaris (FCU) and flexor digitorum superficialis (FDS) provide dynamic stabilization to the medial elbow. It remains unclear how these muscles function during progressive throwing exercises. Our objective was to compare FCU and FDS surface electromyography (sEMG) during a throwing progression. DESIGN: Crossover. SETTING: Laboratory. PARTICIPANTS: Sixteen healthy males. MAIN OUTCOME MEASURES: Participants completed a plyometric throw (PLYO), long-toss 50% (LT50 ), long-toss 75% (LT75 ), and pitch (PITCH)...

OBJECTIVE: The aim of this systematic review is to describe QoL in individuals with PFP, and determine the impact of PFP interventions on QoL. METHODS: Five databases were searched for studies reporting QoL in individuals with PFP, with mean age under 50 years. Data were pooled based on QoL tool (e.g. Knee Injury and Osteoarthritis Outcome Score [KOOS] QoL subscale, Short-Form 36 item health survey [SF-36]) using random-effects models, or through narrative synthesis where inadequate data were available...
