Validation of the Short Form Shoulder Instability Return to Sport After Injury (SIRSI-5) and Its Association With Return to Sports.

Background: Psychosocial readiness is thought to be important in establishing whether athletes are ready to return to sports (RTS). The 5-item Shoulder Instability-Return to Sport After Injury (SIRSI-5) is a short-form version of the 12-item questionnaire (SIRSI-12), which was validated in a postoperative Argentinian population and associated with psychological readiness to RTS. It is unknown if the SIRSI-5 is valid in surgical and nonsurgical populations in other geographic locations.

Preanalytical factors influencing the results of ethanol analysis in postmortem specimens.

Excessive drinking and drunkenness are underlying factors in many fatal accidents, which make the quantitative determination of ethanol in postmortem (PM) specimens an essential part of all unnatural death investigations. The same analytical methods are used to determine ethanol in blood taken from living and deceased persons although the interpretation of the results is more complicated in medical examiner cases owing to various preanalytical factors. The biggest problem is that under anaerobic conditions ethanol can be produced naturally in decomposed bodies by microbial activity and fermentation of blood glucose.

Comparisons of blood alcohol concentrations between initial testing and reanalysis from unopened tubes preserved with 0.25% NaF following refrigerated storage up to 3.93 years.

Few studies support the usage of <1% nominal sodium fluoride (NaF) to preserve ethanol in antemortem blood. Of these studies, several are limited by short study durations of 90 days or less, and there is limited research of authentic samples preserved with <1% NaF. In this retrospective analysis, data from initial and reanalysis testing of blood alcohol concentration (BAC) in antemortem blood collected in 6 mL gray-top tubes (providing 0.

Validity and Reliability of the Kinvent Handheld Dynamometer in the Athletic Shoulder Test.

Context: Long-lever shoulder strength tests may aid clinical decision-making regarding return to sport after a shoulder injury. The Athletic Shoulder Test (AST) was developed to measure force production in 3 positions of shoulder abduction (90°, 135°, and 180°) using force plates. However, handheld dynamometers (HHDs) are more portable, affordable, and may provide valid and reliable results which would increase the clinical utility of long-lever tests.

Preanalytical Factors Influencing the Stability of Ethanol in Antemortem Blood and Urine Samples.

The quantitative analysis of ethanol in blood and other biological specimens is a commonly requested service from forensic science and toxicology laboratories worldwide. The measured blood alcohol concentration (BAC) constitutes important evidence when alcohol-related crimes are investigated, such as drunken driving or drug-related sexual assault. This review article considers the importance of various preanalytical factors that might influence changes in the ethanol concentration in blood after collection and before analysis or reanalysis after various periods of storage.

Purpose: To establish the factor structure of the Shoulder Return to Sport after Injury (SI-RSI) scale and examine how the SI-RSI is associated with the Western Ontario Shoulder Instability Index (WOSI).

Study Design: Cross-sectional study; Level of evidence, 3.

The immediate and subsequent impact of a first-time traumatic anterior shoulder dislocation in people aged 16-40: Results from a national cohort study.

Background: Limited evidence exists which details changes in quality of life, shoulder activity level, kinesiophobia, shoulder pain and disability following a first-time traumatic anterior shoulder dislocation (FTASD) in people treated non-operatively. This study had three objectives: (1) to examine quality of life, pain, disability and kinesiophobia after an FTASD within 12 weeks, (2) to examine whether these variables were different in people with and without recurrent shoulder instability and (3) to assess how these variables changed over 12 months.

Methods: A prospective cohort study was undertaken in people with an FTASD aged between 16 and 40 years.

Line Hops and Side Hold Rotation Tests Load Both Anterior and Posterior Shoulder: A Biomechanical Study.

Background: Clinical tests should replicate the stressful positions encountered during sport participation. Evaluating the kinetic and electromyographical demands of clinical tests enables clinicians to choose appropriate tests for specific sports.

Purpose: To describe the shoulder forces and muscle activation levels during closed chain functional tests of Line Hops (LH) and Side Hold Rotation (SHR).

Statistical comparisons of blood alcohol samples from 6-mL and 10-mL grey-top tubes.

Historically, blood alcohol concentration (BAC) studies utilized a 1% concentration of the preservative sodium fluoride (NaF), leaving an information gap supporting usage of lower concentrations of NaF to preserve ethanol. As many forensic laboratories utilize Becton, Dickinson and Company 6-mL gray-top tubes (0.25% NaF), statistical comparisons were conducted to determine whether significant differences exist between BAC values obtained from 6-mL tubes versus 10-mL tubes (1% NaF).
