Development of Grasping Skills

The video tutorial by Bekah reviews the development of pediatric hand motor skills, focusing on the manipulation of large objects, small objects, and writing skills. It provides a timeline of when these skills typically develop, emphasizing the order of development rather than specific ages. The tutorial covers various grasp types, such as the ulnar palmar grasp, palmar grasp, radial palmar grasp, and radial digital grasp for large objects, and the rake grasp, inferior scissors grasp, scissors grasp, inferior pincer, pincer, and fine pincer for small objects. It also discusses the progression of writing skills from palmar supinate grasp to dynamic tripod grasp.

What are the three major categories of pediatric hand motor skills discussed in the video?

• Manipulation of larger objects, smaller objects, and writing skills

• Manipulation of toys, food, and clothing

• Manipulation of sports equipment, art supplies, and musical instruments

• Manipulation of electronic devices, books, and pencils

Which grasp is characterized by the use of the palm and the ulnar side of the hand?

• Radial digital grasp

• Palmar grasp

• Ulnar palmar grasp

• Fine pincer grasp

At what stage does the thumb start to become more involved in grasping larger objects?

• Ulnar palmar grasp

• Radial palmar grasp

• Radial digital grasp

• Palmar grasp

What is the first type of grasp seen in the development of smaller object manipulation?

• Fine pincer grasp

• Rake grasp

• Inferior pincer grasp

• Scissors grasp

Which grasp involves the thumb coming from the lateral side to push against the hand?

• Fine pincer grasp

• Scissors grasp

• Inferior scissors grasp

• Rake grasp

What is the final step in the development of smaller object manipulation?

• Scissors grasp

• Fine pincer grasp

• Pincer grasp

• Inferior pincer grasp

At what age does the neat pincer or fine pincer motion typically develop?

• Around 1 year

• Around 4 months

• Around 8 months

• Around 10 months

What is the first writing utensil grasp that develops between ages 1 and 2?

• Dynamic tripod grasp

• Static tripod grasp

• Palmar supinate grasp

• Digital pronate grasp

Which grasp involves holding the writing utensil with the fingertips and the forearm pronated?

What is the difference between a static tripod grasp and a dynamic tripod grasp?

• Static involves wrist movement, dynamic involves finger articulation

• Static involves finger articulation, dynamic involves wrist movement

• Static uses four fingers, dynamic uses three fingers

• Static is for larger objects, dynamic is for smaller objects
