Study Notes

Grasp Types and Definitions

Ulnar Palmar Grasp: Involves grasping with the ring and small fingers, lacking thumb opposition.
Palmar Grasp: Held by the middle and ring fingers, pressure applied to the palm; radial in nature.
Radial Palmar Grasp: Utilizes the index and middle fingers; pressure against the radial palm.
Raking Grasp: Features scratching motion using fingers 2-4 without thumb involvement; traps objects between fingers.

Enhanced Pinching and Grasping Techniques

Lateral Key Pinch: Thumb is abducted over the index finger, holding objects against the lateral border of the index.
Radial Digital Grasp: Thumb stabilizes the object while all four fingers provide radial movement.
Three Jaw Chuck Grasp: Involves the thumb, index, and middle fingers to pick up blocks securely.
Inferior Pincer Grasp: Features opposition of the thumb between distal and proximal interphalangeal joints.

Precise Pinching

Neat Pincer Grasp: Opposes thumb to pad of the index or middle finger; commonly used for picking up small objects like Cheerios.
Superior Pincer Grasp: Involves tips of the thumb and index (or middle) finger; suited for delicate grasping of small items.

Functional Grasp Types

Hook Grasp: Flexion of fingers 2-5 to hold objects in a hook-like manner, useful for carrying bags.
Power Grasp: Involves significant force; utilizes proximal joint muscles to maintain control over tools.
Spherical Grasp: Fingers and thumb abducted around a round object, typical wrist extension and finger abduction required.

Specialized Grasping Techniques

Disc Grasp: Characterized by a flattened palm against an object; hyperextension at MCPs with flexion at IPs.
Cylindrical Grasp: Utilizes all fingers wrapping around a cylindrical object, such as jars or glasses.

Pencil Grasp Variations

Palmar Supinated Pencil Grasp: Hold pencil with supinated palmar grip.
Palmar Pronated Pencil Grasp: Grasp pencil in a pronated manner.
Digital Pronated Grasp: Involves thumb and index finger holding the pencil upside down.
Static Tripod Pencil Grasp: Three-finger grasp without significant finger movement, reliant on forearm motion.
Dynamic Tripod Pencil Grasp: Finger positioning at an angle allowing for more dynamic movement.

Reflex and Response Grasp Types

Proprioceptive Placing (Primitive Reflex) - Upper Extremity: Newborn tested upright, reflex elicited by pressure on dorsal hand; results in elbow flexion followed by extension.
Palmar Grasp Reflex: Reflexive curling of an infant's fingers when an object touches the palm.
Traction Response: Infant pulled from lying to a sitting position with initial head lag, followed by active flexion.
