What Are Grasp Patterns?
Grasp patterns refer to the different ways children hold and manipulate objects using their hands and fingers. Differences in grasp patterns contribute to improved coordination in motor skills and enhanced finger dexterity. The presence and development of grasp patterns will significantly influence a child’s ability to interact with their environment. These patterns are essentially to perform everyday activities, such as eating, playing with toys, writing, brushing teeth, and so much more. Understanding the stages of fine motor development is crucial for overall development. It is also important to note that all children develop at their own pace and there is no one timeline for development. These age ranges are approximate ranges and it is okay if the infant develops these skills a little later on.
Types of Grasp Patterns:
Palmar Grasp:
-
- When it occurs: Develops between 0-6 months.
-
- What it looks like: Fingers are wrapped around object and is being held by the entire hand.
-
- Why it is important: Serves as a building block that contributes to the overall motor development and early interactions that are crucial for an infant’s well-being and growth. It is essential for early exploration and bonding.
Radial Palmar Grasp:
-
- When it occurs: Develops between 6-8 months.
-
- What it looks like: Object is still held against the palm, similar to the palmar grasp. However, the object is now being supported by the fingers and thumb on the radial side of the hand.
-
- Why it is important: Having the object more towards the thumb allows for more precision of the movement.
Raking Grasp:
-
- When it occurs: Develops between 7-8 months.
-
- What it looks like: The thumb side of the hand is flexed when gathering an object. The fingers resemble a rake.
-
- Why it is important: Infants use their fingers to rake objects towards themselves, signaling the beginning of intentional hand movements.
Radial Digital Grasp:
-
- When it occurs: Develops between 8-10 months.
-
- What it looks like: The palm is no longer the major stabilizer of the object and the child is able to hold the object between the thumb and fingers.
-
- Why it is important: It is an essential precursor to the development of handwriting grasps.
Pincer Grasp:
-
- When it occurs: Develops between 10-12 months.
-
- What it looks like: An immature pincer grasp develops around 10 months and looks like the isolated finger and thumb grasp with the object towards the bottom of the finger, near the palm. A mature pincer grasp can develop around 12 months and consists of holding an object between the pads of the thumb and another finger.
-
- Why it is important: This grasp helps to develop finger isolation skills. It is also crucial for self-feeding, picking up small objects, and fine motor activities.
Handwriting grasps
Palmar Supinate Grasp:
-
- When it occurs: Develops between 12-18 months.
-
- What it looks like: Infants typically grasp objects with their entire hand, using a palmar (palm) grasp. They have limited fine motor control during this stage. In this grasp, the fingers and thumb wrap around an object, and the wrist is usually in a supinated (turned upward) position.
-
- Why it is important: The palmar supinate grasp is an early form of voluntary grasping that emerges as the reflex becomes more controlled.
Digital Pronate Grasp:
-
- When it occurs: Develops between 2-3 years.
-
- What it looks like: This grasp is characterized by the fingers wrapping around an object, and the palm is also involved in the grip.
-
- Why it is important: As toddlers develop more control, they start using their fingers (digits) to grasp objects. The wrist may still be turned downward (pronated). This grasp allows for the gradual shift from using the entire palm to write to beginning to utilize the fingers more actively.
Static Tripod Grasp:
-
- When it occurs: Develops between 3-4 years old
-
- What it looks like: It is a 3 finger grasp, two fingers pinching the writing utensil and the 3rd (middle) finger tucked to the side of the pencil, forming a tripod. The fingers and even wrist are static in the movement.
-
- Why it is important: This grasp provides stability and control with movement and aids in activities such as buttoning clothes, tying shoelaces, and manipulating small objects with precision.
Dynamic Tripod Grasp:
-
- When it occurs: Develops around 5 years old.
-
- What it looks like: Same finger placement as the static tripod grasp, but instead of the movement originating from the shoulders, the fingers and wrist provide the movement. It enables precision in writing, drawing, and manipulating objects.
-
- Why it is important: It helps refine their fine motor skills. It involves holding a writing tool with the thumb and first two fingers while allowing movement for writing and drawing.
Grasp patterns are integral to your child’s development, influencing everything from basic exploration to complex fine motor tasks. Recognizing and supporting the progression of these patterns is vital for promoting healthy motor development. As primitive reflexes become more integrated, you will begin to see the presence of more sophisticated grasping patterns. If you have concerns about your child’s grasp development, consulting with an occupational therapist can provide valuable insights and support.
