What does the overhead squat screen (OSS) assess?

The overhead squat screen (OSS) is primarily designed to dynamically evaluate multiple body areas, making it an essential tool in assessing movement patterns. During the overhead squat, various aspects of an individual's biomechanics are scrutinized, including the alignment and movement of the hips, knees, and ankles, as well as upper body stability and mobility. This comprehensive assessment allows coaches to identify muscular imbalances, movement deficiencies, or restrictions that might affect an athlete's performance and increase the risk of injury.

By observing how the body performs during the overhead squat, coaches can gain insights into the functionality of the kinetic chain as a whole. It simultaneously evaluates the flexibility of the lower extremities, the strength of the core and stabilizing muscles, and the coordination required to maintain proper form throughout the movement. This is why the ceiling option is deemed the most accurate, as it encompasses a holistic view of the body's dynamic interaction during a fundamental movement.
