8.3 Superficies táctiles

Summary

This exercise is designed to improve tactile recognition by progressively challenging the participant with different textures. Starting with basic surfaces like smooth wood and rough sandpaper, the participant's ability to differentiate tactile sensations is gradually expanded by introducing more complex surfaces and involving multiple fingers. The exercise culminates in the comparison of tactile sensations between both hands, refining the participant's ability to transfer and anticipate textures. The goal is to enhance sensory awareness and tactile precision, helping individuals improve their fine motor and sensory perception skills.

Takeaways

• 😀 The hand is the organ of touch, and the ability to perform specific grips relies on tactile interaction with objects.
• 😀 The first level of calibration introduces two distinct tactile surfaces: a smooth one (raw wood) and a rough one (abrasive paper).
• 😀 The patient should explore the surfaces using their index finger, ensuring tactile perception without relying on auditory cues.
• 😀 In the second level, the exercise becomes more complex by involving all fingers and introducing new tactile surfaces like synthetic grass.
• 😀 When working with the thumb, its movement is different from the other fingers, requiring specific handling (sideways placement).
• 😀 The third level involves anticipating the tactile sensation using different fingers, fostering recognition and anticipation of surfaces.
• 😀 In the third level, the patient is guided to predict and match surfaces with specific fingers, enhancing recognition accuracy.
• 😀 The fourth level focuses on comparing tactile sensations between the right and left hands, improving tactile differentiation skills.
• 😀 In the fourth level, the patient transfers tactile sensations from their right hand to the left hand, strengthening their ability to compare and contrast sensations.
• 😀 Throughout the exercise, attention to finger placement and movement is key, especially when using the thumb and pinky fingers.
• 😀 The exercise progresses gradually, increasing complexity with each level, encouraging full engagement and improving tactile recognition abilities.

Q & A

What is the purpose of the tactile surface recognition exercise described in the transcript?

The exercise is designed to help individuals recognize different tactile surfaces using their sense of touch. It emphasizes the importance of touch for performing specific actions and understanding the textures of various materials.

Why is the hand considered an essential organ for this exercise?

The hand is the organ of touch, and by executing specific grips, we engage in a dialogue with objects through tactile perception, which allows us to perform actions accurately.

What materials are used in the exercise for tactile surface recognition?

The exercise uses a variety of materials, including rough surfaces like sandpaper, smooth ones like wood, felt, and leather. The materials can be adapted depending on the domestic environment.

What is the first level of calibration in this exercise, and what is the goal?

The first level of calibration involves using two very different surfaces: a smooth surface, like raw wood, and a rough one, like sandpaper. The goal is to allow the participant to distinguish between different textures using their index finger.

How should the hand be positioned for the first level of tactile recognition?

The hand should be placed open with the palm facing the table. The index finger is used to touch and distinguish between the two different surfaces.

What precaution is taken when using abrasive surfaces in the exercise?

The abrasive surface should not be too harsh to avoid injuring the participant during the tactile recognition exercise.

How does the exercise progress to the second level of calibration?

In the second level, the complexity increases by adding more surfaces for the participant to recognize and involves using all the fingers, not just the index finger.

What role does the thumb play in the tactile surface recognition exercise?

When using the thumb, the grip changes slightly. The thumb is positioned differently from the other fingers, and the hand is rotated sideways to facilitate recognition through this specific finger.

What is the third level of calibration, and how does it differ from the previous levels?

The third level introduces anticipation. The participant is asked to predict what they will feel before actually experiencing the tactile sensation, using a specific finger like the middle finger.

What is the fourth level of calibration, and how is it performed?

In the fourth level, the participant compares the tactile recognition between their right and left hands. They will try to transfer the sensation felt in one hand to the other, allowing them to enhance their tactile perception across both hands.
