The purpose of humeroulnar distraction is to increase
flexion (or extension) of the elbow joint.
The purpose of humeroradial posterior glide is to increase
extension
The purpose of radioulnar anterior glide is to increase
supination of forearm
The purpose of radioulnar posterior glide is to increase
pronation of forearm
