movement occurring at diarthrotic joints

dorsiflexion

movement that decreases the angle between the dorsum (superior surface) of the foot and the anterior surface of the shin

flexion

decreases angle between anterior surface of the body (the knees and toes are exceptions--flexion at these joints deceases the angle between posterior surfaced

adduction

movement toward the body midline. (adduction of the figures and toes are exceptions. the movement is toward the midline of the hand and foot)

extension

usually increases the angle between anterior surfaced of the body (knees and toes are exceptions--extension at these joints increases the ankle between posterior surfaced. anatomical position, most joint are extended)

circumduction

a movement of a body part so it describes a cone. (proximal end of the body part remains relatively stationary, while distal end moves in a circle

eversion

a movement of the foot that causes the sole ot face laterally

inversion

a movement of the foot that causes the sole to face the interior surface fo the shin

supination

a movement of the forearm that runs the palm anteriorly

pronation

a movement of the forearm that turns the palm posteriorly

plantar flexion

a movement that increases the angle between the dorsum of the foot and the anterior surface of the shin

hyperextension

a movement where extension is carried beyond anatomical position

rotation

a movment of a body part around its long axis

abduction

movement away from the body midline (abduction of fingers and toes are exceptions. the movement is away from the midline of the hand or foot rather than the body's midline. The midline of the hand is the middle finger, and the midline of the foot is the second toe
