A Tactile Automated Passive-Finger Stimulator (TAPS)
Published on: June 3, 2009
Resumen
Este estudio mejoró la percepción táctil para la detección de movimiento precordial. Un simple dispositivo de retención de dedos mejoró significativamente la mano.
Área de la Ciencia:
- Ingeniería Biomédica Ingeniería Biomédica.
- Fisiología Humana Fisiología Humana
- Instrumentación médica y equipo médico.
Sus antecedentes:
- La percepción táctil es crucial para el examen físico.
- La sensibilidad de la mano como transductor para el movimiento precordial es limitada.
- Mejorar la sensibilidad a la palpación puede mejorar las capacidades de diagnóstico.
Objetivo del estudio:
- Para determinar la respuesta de frecuencia de la mano en la percepción táctil.
- Para mejorar la sensibilidad de la mano como un transductor para el movimiento precordial.
- Para mejorar la evaluación clínica de la actividad precordial.
Principales métodos:
- Investigó los umbrales de la sensación táctil en 10 sujetos a través de frecuencias subaudibles (1-40 Hz).
- Utilizó un generador de impulsos para manipular la amplitud de movimiento.
- Evaluó el efecto de un disco de retención de dedos en la sensibilidad táctil.
Principales resultados:
- Se requerían movimientos brutos para la detección de umbrales a bajas frecuencias.
- Un disco de retención de dedos aumentó la sensibilidad táctil en más de cuatro veces.
- El dispositivo permitió la percepción del empuje sistólico y las ondas de llenado rápido.
Conclusiones:
- La sensibilidad táctil de la mano para el movimiento precordial se puede mejorar significativamente.
- Una simple retención del dedo mejora la capacidad de detectar sutiles movimientos precordiales.
- Esta técnica permite una mejor palpación clínica del precórdio, incluso en áreas típicamente inmóviles.

01:33Somatosensation
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

01:16Sensory Functions of the Skin
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

01:15Sensory Modalities
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

01:11Sensory Perception: Organization of the Somatosensory System
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...

01:27Tactile and Chemical Senses
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...
