Seated Thoracic Rotation Assessment
Introduction
The Seated Thoracic Rotation Assessment evaluates rotational mobility and control in the upper trunk and hips. This assessment is essential for identifying limitations or asymmetries that may impair performance or increase injury risk in rotational activities.
Purpose and Functionality
Proper trunk and hip rotation is essential for effective transfer of force, balance, and coordination in rotational sports and everyday function. This assessment helps pinpoint restrictions that could lead to compensatory movement and injury.
What It Evaluates
Upper Trunk Rotation: Assesses thoracic spine mobility and core control during rotational movement, which is vital for many athletic and daily activities.
Hip Rotation: Evaluates the ability of the pelvis and hips to rotate, highlighting lower-body mobility and movement efficiency.
Thoracic Rotation Component
Thoracic rotation assesses the mobility of the upper spine while the pelvis remains stable. This movement is essential for activities that involve turning, swinging, or throwing. Limited thoracic rotation may indicate stiffness in the spine or weakness in the core, which can lead to compensatory patterns, postural issues, and injury risk.
Thoracic rotation is measured as the angular difference between the shoulder line and the hip line while seated. Rotation angles greater than 60° score 100%, less than 30° score 0%, and scores in between are scaled linearly.
