![]() Remember, the radius is on the thumb side, which where you check the radial pulse. These movements are also referred to as radial deviation and ulnar deviation. Adduction of the wrist has it going in the opposite direction, toward the body’s midline. Abduction of the wrist has it moving away from the body’s midline, in the same direction as arm abduction. When determining abduction and adduction of the wrist, I find that it helps to stand in the anatomical position. Wrist Abduction and Adduction (Ulnar Deviation & Radial Deviation) Adduction of the thumb has it added back to the hand. Abduction of the thumb has it moving within the sagittal plane, in an anterior motion. The thumb (pollex) is different from the fingers. When it deviates toward the body, it’s called medial abduction. When the middle finger (3rd digit), which serves as the midline reference of the hand, deviates to the away from the body, it’s called lateral abduction. During arm adduction (or shoulder adduction), you ADD them right back toward the midline.įinger abduction occurs when the fingers move away from the midline reference of the hand, whereas finger adduction occurs when you add them back toward the hand’s midline reference. Arm Abduction and Adductionĭuring arm abduction (also called shoulder abduction), the arms move away from the body’s midline. Let’s take a look at examples of abduction and adduction on the body. What is Adduction?Īdduction (think: ADDuction) occurs as the structure is ADDED back toward its midline reference point. The structure is being moved away from its midline reference point. That’s exactly what’s going on with this movement. What does “abduct” mean? When you hear on the news that a man was abducted, you know it means that someone took him away. ![]() However, the thumb is a notable exception to this rule, as it moves within the sagittal plane during abduction and adduction when in the anatomical position.Ībduction (think: ABDUCTion) is the movement of a structure away from its midline reference point. Assessment of thumb abduction based on distance in the first web is recommended in terms of reproducibility.Unlike flexion and extension movements, which mostly take place within the sagittal plane, you’ll notice that abduction and adduction motions mostly take place within the frontal, or coronal, plane. Inter-observer reproducibilities by distances were also high (ICCs = 0.79 and 0.81) compared with those by angles (ICCs = 0.28 and 0.42). Intra-observer reproducibilities by distances were high with ICCs between 0.74 and 0.89, compared with those by angles with ICCs between 0.28 and 0.71. Measurements were repeated in three weeks and their reproducibility was assessed by the intraclass correlation coefficient (ICC). Two independent observers measured the thumb abduction in 30 volunteers by the following four methods: distance between the thumb tip and the flexion crease of the index finger proximal interphalangeal joint distance between the flexion crease of the thumb interphalangeal joint and the proximal palmar crease angle between the thumb and index metacarpals and angle between the thumb and index proximal phalanx. The reproducibilities of various measurements of thumb abduction were compared.
