Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb
The drop arm test is designed to determine a patient's ability to sustain humeral joint motion through eccentric contraction as the arm is taken through the full motion of abduction to adduction. It will determine if the patient has an underlying rotator cuff dysfunction.
To measure the horizontal deviation, the Maddox rod is placed in front of the right eye (it is done on both eyes) with the cylinder horizontal, making the red line vertical. The patient is then asked whether the white light is superimposed on the red line, or if it is to the left or right of the red line.
Abduction is a motion that pulls a structure or part away from the midline of the body, carried out by one or more abductor muscles. In the case of fingers and toes, it is spreading the digits apart, away from the centerline of the hand or foot. [ 15 ]
Wartenberg's sign is a neurological sign consisting of involuntary abduction of the fifth (little) finger, caused by unopposed action of the extensor digiti minimi. [ 1 ] [ 2 ] This commonly results from weakness of some of the ulnar nerve innervated intrinsic hand muscles -in particular the palmar interosseous muscle to the little finger ...
(in abduction: 95°; in adduction: 70°) Infraspinatus: Infraspinous fossa of scapula Greater tubercle of humerus Teres minor Upper two thirds of lateral border of scapula Greater tubercle of humerus Posterior fibers of deltoid Spine of scapula Middle of lateral surface of shaft of humerus Medial rotation (in abduction: 40°–50°; in ...
The shoulder abduction relief test, also called Bakody's test, is a medical maneuver used to evaluate for cervical radiculopathy. [1] Specifically, this test is used to evaluate for nerve root compression at C5-C7. It is often used when a patient presents with neck pain that radiates down the ipsilateral upper extremity. [2]
True abduction: supraspinatus (first 15 degrees), deltoid; Upward rotation: trapezius, serratus anterior Arm adduction [14] Arm adduction is the opposite motion of arm abduction. It can be broken down into two parts: downward rotation of the scapula and true adduction of the arm.
