What is the normal active shoulder adduction range?

• A. 30-45 degrees
• B. 0-15 degrees
• C. 60-75 degrees
• D. 15-30 degrees

Answer: (A)

When you assess active shoulder adduction, you’re measuring how far the arm can be moved toward the midline in the frontal plane from an abducted position. The amount a healthy person can actively bring the arm toward the body is typically about 30 to 45 degrees. This range reflects the balance of muscle forces (like the pectoralis major and latissimus dorsi) and the joint’s soft tissue restraints that limit how far the arm can actively move without assistance. Movements beyond this range are usually not part of a normal active adduction ROM and, if needed, can involve passive motion or additional scapulothoracic contribution. So, 30–45 degrees is considered the normal active adduction range.
