Somatosensation

Somatosensation

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.

Sensory Functions of the Skin

Sensory 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...

Pulse Assessment Sites

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Assessment of the Cardiovascular System III: Palpation

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Area of Science:

Biomedical Engineering
Human-Computer Interaction
Sensory Feedback Technology

Background:

Tactile feedback expands human-technology interaction beyond visual and auditory channels.
Lateral skin stretch is a promising tactile feedback modality for directional cues using a single actuator.

Purpose of the Study:

To investigate human sensitivity to lateral skin stretch on the lower leg.
To determine the optimal parameters for directional perception via skin stretch.
To identify suitable anatomical locations for tactile feedback devices.

Main Methods:

Experiments involved presenting 32 stimuli with varying displacements (0.2-2.0 mm) and speeds (0.5-4.0 mm/s).
Sensitivity was assessed across nine distinct locations on the human lower leg.
Participant accuracy in perceiving left and right directional cues was measured.

Main Results:

Increased stimulus displacement and speed led to higher accuracy in directional perception.
Three specific locations demonstrated high performance: soleus, upper calcaneal tendon, and lower fibularis longus.
These locations achieved a mean accuracy of at least 85% for directional cues.

Conclusions:

Lateral skin stretch is an effective method for conveying directional information through tactile feedback.
Optimal performance is achieved with higher displacement and speed parameters.
The soleus, upper calcaneal tendon, and lower fibularis longus are well-suited for implementing skin stretch-based tactile feedback systems.
