Upper Body Joint Angles and Movements Quiz

Joint Range of Motion

• The hip joint allows for the greatest range of flexion due to its ball-and-socket structure.
• The humeroulnar joint has a flexion range of approximately 140-150 degrees.
• The shoulder joint (glenohumeral joint) allows for the greatest range of extension, reaching approximately 60 degrees.

Glenohumeral Joint Movement

• The range of abduction in the glenohumeral joint without moving the scapula is about 90-120 degrees.
• Internal rotation in the cervical spine can typically achieve a range of about 70-80 degrees.
• Abduction in the glenohumeral joint with the scapula contributes to an increased range, measured up to 180 degrees when including scapular motion.

Talocrural Joint Mobility

• The talocrural joint demonstrates a dorsiflexion range of approximately 20 degrees.

Additional Joint Flexibility

• Extending the humeroulnar joint can reach around 0-10 degrees beyond a straight position.
• The lumbar spine allows for a flexion range of about 40-60 degrees.
• In the glenohumeral joint, adduction to an estimated range of 30-50 degrees occurs without scapular assistance.
• The internal rotation of the humeroulnar joint is limited, typically around 60-90 degrees.
