The arches of the hands may need to compensate for strength and dexterity in the fingers and that precise placement that the ring finger adds to the shaft of the pencil just isn’t as targeted with the arches of the hand and the stability offered through the ulnar side of the hand. When the child that the uses a quadrupod grp on the pencil is forced to use a tripod grasp, you may see a decrease in written work legibility due to decreased stability. Some may say that the quadrupod grasp is more restrictive than the tripod grasp, however that extra stability can actually promote more mobility in the pencil and be used in very efficient and effective handwriting. Research tells us that the quadrupod grasp is a very functional grip and the use of one extra finger (as opposed to the traditional sense of a tripod grasp) is actually very functional in written work. However, don’t get stuck on a quadropod grasp if this type of grip is used with older children or if students are established with their quadrupod grasp! Quadrupod grasp or Tripod Grasp? The quadrupod stage is an important part of grasp development as the fingers move into a dynamic position with pronation and extension of the wrist. A quadrupod grasp can also occur with the pencil resting on the side of the ring finger. Quadrupod Grasp- If the thumb opposes the pointer finger, middle finger, and ring finger this may be called a quadrupod grasp. Quadrupod grasp progresses from a static form to a dynamic form where there is fluid motion and repositioning in the joints of the hands. The quadrupod grasp is considered a four finger grasp, in which four fingers (thumb, pointer finger, middle finger, ring finger) are used to hold the pencil. You might have noticed this term was mentioned a few times above, and in difference areas of development through the progression of pencil grasp development. One thing that is important to mention is the quadrupod grasp. Lateral Quadrupod Grasp- Grasp is similar to the lateral tripod grasp, with its thumb wrapped positioning of the thumb, but uses the pointer, middle, and ring fingers are on the pencil shaft and manipulate the pencil. Dynamic Quadrupod Grasp- Grasp is similar to the dynamic tripod grasp, but opposition includes the thumb, pointer finger, middle finger on the pencil shaft.Ĥ. Distal mobility occurs, but it is the index and middle fingers manipulating the pencil.ģ. This grasp is sometimes called a thumb wrap grasp because the thumb is not involved with the distal movement of the pencil. The tip of the thumb may bend over (or flex) over the pencil in a “wrapped” position. Lateral Tripod Grasp- Thumb is pressed in against the pencil (or adducted) to hold the pencil against the side of the pointer finger. Note that a true dynamic tripod grasp may not be established up until around 14 years of age.Ģ. Pencil movements occur via manipulation of the fingers and hand. Dynamic Tripod Grasp- (4-6/7 years) Thumb and pointer finger hold the pencil as it rests on the last joint of the middle finger.
