BackgroundMusculoskeletal injuries are a significant burden to United States Army Special Operations Forces. The advanced tactical skill level and physical training required of Army Special Operators highlights the need to optimize musculoskeletal characteristics to reduce the likelihood of suffering a recurrent injury.PurposeTo identify the residual impact of previous injury on musculoskeletal characteristics.Study DesignCross-sectional study; Level of evidence, 3.MethodsIsokinetic strength of the knee, shoulder, and back and flexibility of the shoulder and hamstrings were assessed as part of a comprehensive human performance protocol, and self-reported musculoskeletal injury history was obtained. Subjects were stratified based on previous history of low back, knee, or shoulder injury, and within-group and between-group comparisons were made for musculoskeletal variables.ResultsKnee injury analysis showed no significant strength or flexibility differences. Shoulder injury analysis found internal rotation...
