Movements of the joints : The Anatomical Position is the point of reference for all movements of the joints. The Anatomical Position is a standardized posture involving upright standing with the elbows supinated. o flexion - joint angle decreases o extension - return from flexion o abduction - movement away from mid line o adduction - movement toward mid line o hyper flexion - beyond vertical in flexion o hyper extension - beyond vertical in extension o hyper abduction - beyond vertical in abduction o hyper adduction - beyond vertical in adduction(with slight flexion) o lateral flexion - lateral bending of the trunk (frontal plane, sagittal axis) o left and right rotation – rotation of the head in a horizontal plane around a vertical axis

Unformatted text preview: extension (lateral) o plantar flexion – motion of the ankle/foot so that plantar (bottom) surface of the foot approaches the floor o dorsi flexion – motion of the ankle/foot so that dorsal (top) surface of the foot moves toward the knee o inversion - medial border of foot rises (frontal plane, sagittal axis) o eversion - lateral border of foot rises (frontal plane, sagittal axis) o circumduction - combines flexion, extension, abduction, and adduction in one fluid motion o supination - lateral rotation of elbow o pronation - medial rotation of elbow o pronation of foot combines: eversion dorsi flexion abduction (toeing out) – this occurs at the knee (lateral rotation) o supination of foot combines: inversion plantar flexion adduction (toeing in) – this occurs at the knee (medial rotation)...
