Webster's New World Medical Dictionary

hypermobility syndrome
A condition in which
joints can move beyond the normal range of motion
predisposing them to injury and pain. Symptoms of
hypermobility syndrome can include pains in knees,
fingers, hips, and elbows, and the affected joints
may sprain or dislocate. Joint hypermobility can dis-
appear with aging from childhood to adulthood.
Some persons have genetic conditions that are asso-
ciated with hypermobility syndrome, such as Ehlers-
Danlos syndrome. Also known as joint hypermobility
syndrome. See also 
Ehlers-Danlos syndrome.
