Goniometer Alignment of Elbow and Forearm

Question 1

Elbow Flexion

Answer 1

• fulcrum over the lateral epicondyle of humerus
• proximal arm aligned with the lateral midline of humerus
• distal arm aligned with lateral midline of radius (radial head & radial styloid for reference)

Question 1

Elbow Extension

Answer 1

same as elbow flexion

Question 2

Forearm Pronation

Answer 2

• fulcrum laterally and proximally to ulnar styloid process
• proximal arm aligned parallel to anterior midline of humerus
• distal arm placed across the dorsal surface of the forearm

Question 3

Forearm Supination

Answer 3

• fulcrum medially and proximally to ulnar styloid process
• proximal arm aligned parallel to anterior midline of humerus
• distal arm across the ventral surface of the forearm

Question 4

Biceps Brachii

Answer 4

• fulcrum over lateral epicondyle of humerus
• proximal arm aligned with lateral midline of humerus
• distal arm aligned with lateral midline of ulna

Question 5

Triceps Brachii

Answer 5

• fulcrum over lateral epicondyle of humerus
• proximal arm aligned with lateral midline of humerus
• distal arm aligned with lateral midline of radius
