Preventive interventions for lateral ankle sprains: A systematic review and meta-analysis.

Objective: To evaluate the effect of preventive interventions for lateral ankle sprain in the general population.

Data Sources: A search of PubMed, EMBASE, Cochrane CENTRAL, Medline, CINAHL, and ClinicalTrials.gov was conducted up to August 2022.

Concurrent Validity and Reliability of a Handheld Dynamometer in Measuring Isometric Shoulder Rotational Strength.

Context: Measuring isometric shoulder rotational strength is clinically important for evaluating motor disability in athletes with shoulder injuries. Recent evidence suggests that handheld dynamometry may provide a low-cost and portable method for the clinical assessment of isometric shoulder strength.

Objective: To investigate the concurrent validity and the intrarater and interrater reliability of handheld dynamometry for measuring isometric shoulder rotational strength.

Influence of Shoulder Position on Functional Control Ratio During Isokinetic Assessment.

Context: One of the possible mechanisms leading to secondary impingement syndrome may be the strength imbalance of shoulder rotators which is known as functional control ratio (FCR). The FCR is a ratio dividing the eccentric peak torque of the external rotators by the concentric peak torque of the internal rotators. Previous studies have focused on the reproducibility and reliability of isokinetic assessment, but there is little information on the influence of variable shoulder positions on FCR.
