Movement Terminology
Adduction
if a joint brings a limb medially toward the body's midline ("adding to the body")
Abduction
if a joint moves a limb laterally away from the midline ("abduct or carry away")
Inversion
Turning the foot inward by a combination of movements in several bones of the foot. In this movement the medial side of the foot elevates and the sole of the foot turns medially.
Eversion
Turning the foot outward by a combination of movements in several bones of the foot. In this movement the lateral side of the foot elevates and moves the sole laterally.
Dorsiflexion
Upward movement of foot (toes) due to movement at the ankle joint.
Rotation
When a twisting, pivoting movement occurs along any part of the vertebral column. In the neck, this would result in a 'shaking the head no' movement
Lateral Rotation (External Rotation)
When the shoulder or hip joints turn the limb away from the midline
Medial Rotation (Internal Rotation)
When the shoulder or hip joints turn the limb in toward the midline
Hyperextension
extension beyond anatomical position (beyond straight 180 degrees) or beyond the normal range for a joint
Retraction (adduction)
Posterior movement of scapula, clavicle, head and jaw ("retreat")
Elevation
Superior movement of the scapula and jaw
Flexion
movement that bends a joint or brings the bones closer together (decreasing the angle)
Extension
movement that straightens or opens a joint (increasing the joint angle up to 180 degrees)
Lateral flexion
A side-bending motion that only occurs when the vertebral column bends laterally to the side. This can occur in the cervical vertebrae (to bend the neck to the side) and/or along the thoracic and lumbar vertebrae (to bend the torso).
Circumduction
A cone shaped movement that is a combination of flexion, extension, adduction and abduction that only occurs at the hip and shoulder joints.
Protraction (abduction)
Anterior movement of scapula, clavicle, head and jaw ("protrude")
Depression
Inferior movement of the scapula and jaw
Plantarflexion
Movement at the ankle to point your foot (toes) into the earth.
Opposition
Movement that occurs at the carpometacarpal joint of the thumb which moves the thumb across the palm towards the 1st finger (pinkie)
Deviation
Movement to the side which can occur at the jaw or wrist.
