![]() ![]() ![]() Any muscle that creates this type of motion is termed an abductor. Abduction of the wrist, moving the hand away from the body at the wrist when that arm is at the person’s side, is called radial deviation. Raising the arms laterally, to the sides and moving the knees away from the midline are some examples of abduction. For fingers and toes, abduction spreads the digits away from the hand or foot’s centerline of hand or foot. The right arm was abducted approximately 80 degrees from the patients right side and secured on an arm board without removal of the shoulder restraint from. Arm abduction has an arc of motion of approximately 0180°, flexion and extension is approximately 180°, and internal and external rotation is approximately 150°. Swinging the hands from the side of the body up to the shoulder or higher is abduction. So in people with normal eyes, when one eye is adducted, the other abducts.Ībduction is any motion of the limbs or other body parts that pulls away from the midline of the body. At the same time, the left eye is abducted, moving away from the midline of the face and looking left. Any muscle that creates this type of motion is called an adductor.įor normal eyes (not cross-eyed, for example) when the right is adducted, it moves toward the center of the face and looks left. Adduction of the wrist, moving a hand toward the body at the wrist when that arm is at the person’s side, is also called ulnar deviation. Closing arms to the chest or bringing knees together are other examples of adduction. For example, if a person has their fingers spread wide apart, bringing them together would be adduction. For fingers or toes, adduction brings the digits toward the center of the hand or foot. So, if a person has their arms straight out at the shoulders and brings them down to their sides, it is adduction. This muscles action is to initiate abduction of the arm, the reason why it does not continue to abduct throughout the motion is because its line of pull. In medicine and biomechanics, movements of limbs and other body parts toward or away from the center line of the body (a line that runs up and down the center of the human body) are termed adduction and abduction, respectively.Īdduction is the movement of a body part toward the body’s midline.
