Information so obtained should always be supplemented by local 

 manipulation and by passive movement, such as flexion, extension, 

 abduction, adduction and rotation of the joints.

 increased sensibility, articular crepitation or friction, and to diagnose 

 fractures with or without displacement, ruptures of tendons or 

 ligaments, etc.
