Groups of Movements • Gliding • Angular • Rotation • Special Movements
Gliding • A simple movement in which relatively flat bone surfaces move back-and-forth and side-to-side relative to one another. • Limited in range by the articular capsule and ligaments of the joint • Occurs in Planar Jonits (carpals, tarsals, sternoclavicular)
Angular Movements • There is an increase or decrease in the angle between articulating bones • Flexion, Extensions, Abduction, Adduction
Flexion/Extension • Flexion - A decrease in the angle between articulating bones • Extension – An increase in the angle between articulating bones • Found in hinge, pivot, condyloid, saddle and ball-and-socket joints • HYPEREXTENSION – extension beyond anatomical position
Abduction/Adduction • Abduction – movement away from the midline of the body • Adduction – movement toward the midline of the body • Found at condyloid, saddle and ball and socket joints
Circumduction • Movement of the distal end of a body part in a circle • Found at ball-and-socket joints
Rotation • A bone revolves around its own longitudinal axis • Found at pivot and ball and socket joints
Special Movements • Occur only at certain joints • Include elevation, depression, protraction, retraction, inversion, eversion, dorsiflection, plantar flexion, supination and pronation
Elevation - upward movement of a body part (closing your mouth) • Depression – downward movement of a body part (opening your mouth) • Protraction – movement of a body part forward (mandible or clavicles) • Retraction – returning a protracted part to anatomical position
Inversion – movement of the soles medially so they face each other • Eversion – movement of the soles laterally so they are away from eachother • Dorsiflexion – Bending the feet upward (like standing on your heals) • Plantar Flexion – Bending the feet down (like standing on your toes)
Supination – turning the palm upward • Pronation – turning the palm downward
