Which movement pattern is described by tests of internal and external rotation and their relevance to overhead activities?

• A. Cervical Patterns
• B. Upper Extremity Patterns
• C. Lower Extremity Patterns
• D. Spinal Patterns

Answer: (B)

Tests of internal and external rotation focus on the shoulder complex and how rotation ability supports reaching and moving the arms overhead. Overhead activities rely on coordinated shoulder rotation, scapulothoracic rhythm, and thoracic spine mobility. Assessing these rotations helps determine if the upper extremity movement patterns are functioning properly to achieve overhead tasks without compensations. That’s why this describes upper extremity patterns—the area that centers on the shoulder and arm functions essential for overhead movements. The other regions involve the neck, the spine in a broader sense, or the legs, which don’t directly address the rotational capacity and coordination needed for overhead work.
