Study Notes
Dexterity and Fine Motor Skills
- Dexterity involves fine motor skills for controlled, agile movements in intricate tasks.
- It requires skill, control, and proficiency in precise hand/finger movements (grasp/release, finger/thumb coordination, wrist movements).
- Crucial for tasks like picking up small objects, writing, using tools.
- Dexterity development allows increasingly complex hand/finger actions.
- Fine motor skills and dexterity are interconnected. Fine motor skills are broader, while dexterity focuses on refined/skilled hand use.
Motoric Hand Separation
- Good dexterity requires motoric hand separation (dividing the hand).
- Skill side (thumb, index, middle fingers) for fine motor tasks (writing, small objects).
- Stabilization side (ring, little fingers) for balance/support during precision tasks (scissors, beads).
- This separation is crucial for performing tasks requiring precision and stability.
- This skill develops through activities encouraging independent use of both hand sides. Can be supported by occupational therapy.
Developmental Progression of Grasping
- Stage 1: Crude Palmer Grasp (4-5 months) - Entire hand wraps around object. Fingers close, thumb inactive, imprecise, for larger objects.
- Stage 2: Palmer Grasp (5-6 months) - Object held in palm, all four fingers hold against palm. Thumb begins to oppose fingers; more secure than the previous stage. Less precise.
- Stage 3: Radial Palmer Grasp (6-7 months) - Thumb and radial side of hand hold object. Thumb opposes fingers for more control. Held in palm, but increased thumb participation.
- Stage 4: Inferior Pincer Grasp (8-10 months) - Thumb and side of index finger pick up objects. Pads of fingers used, not tips. Significant step toward fine motor control for picking up smaller objects.
- Stage 5: Pincer Grasp (10-12 months) - Tips of thumb and index finger pick up small objects with precision. Allows fine motor tasks (beads, grains) crucial for hand-eye coordination.
Hand-Grip Development Beyond Infancy
- Palmer Supinate Grasp (12-18 months): Entire fist holds writing/drawing tool; palm faces up; broad strokes; primarily shoulder movement.
- Digital Pronate Grasp (2-3 years): Fingers hold tool, palm faces down, index finger may point down. Thumb and other fingers wrap around; more control; elbow and wrist movement.
- Immature Static Tripod/Quadrupod Grasp (3-4 years): Static tripod uses thumb, index, middle fingers, forming a tripod shape. Static quadrupod adds ring finger. Fingers relatively fixed; more refined control with wrist/elbow movement.
- Dynamic Tripod/Quadrupod Grasp (4 years+) - Dynamic tripod uses three fingers; dynamic quadrupod uses four. Precise finger movements for controlled writing, drawing. Mature grasps reflect advanced object manipulation ability.
