Typical Pencil Grasp Development for Kids
Weakness in the index and middle fingers.
A pincer grasp simply means the tips of the thumb and index finger come together, a motion we use to pick up small items, pull zippers, and button shirts.
This skill usually develops in babies around 9 to 10 months old.

A military attack by two coordinated forces that close in on an enemy position from different directions. Unlike gross motor skills that focus on the movement of the limbs, the pincer grasp is a fine motor skill requiring the movement of just two fingers.
Neat pincer grasp uses the tips of the thumb and pointer finger to stabilize objects.
Patient is not able to perform the pincer movement of the thumb and index finger i.e. This joint is commonly affected by arthritis. Fastenings and tool use e.g. Abduction and adduction are used to describe the thumb’s motion out of and into the palm, respectively.

The pincer grasp is the ability to hold something between the thumb and first finger. Our thumbs are important to providing the pincer movement that allows precision of hand movement.
During this movement the thumb is opposed and flexed while the fingers are flexed at the mcp, pip and the dip.
A stener lesion is a complete tear of the ulnar collateral ligament. The development of grasp is influenced by a child’s growing interest in objects and desire to hold them. Because we don't want the challenge of holding a pencil to interfere with what the child wants to create with that pencil, we provide ample opportunities to build the muscles of the hand the child will need to manage a stylus, long. When using a pincer grasp, children use the pads of the thumb and finger to stabilize the object.
When the thumb loses its ability to pinch against a finger (pincer grasp), muscles in the hand begin to atrophy.
But even though the movements aren’t big, grasping an object between the thumb and pointer finger requires a lot of coordination between muscles and the nervous system. The patient is not able to flex or hold anything between thumb and index finger. We all revert to raking for small objects in the dark, and blind children must be taught to use a pincer grasp ( fig. Of the thumb and index finger, permitting measurement of pincer grasp aperture.
Because of value of thumb, reimplantation at any level is recommended.
Many cases of ain syndrome arise secondary to transient neuritis, although nerve compression and trauma are known etiologies as well. Ain syndrome is an isolated palsy of these three muscles.
