Distinguishing Separate Pressure Points

* Sensations: The cutaneous sensations like touch, pressure, vibration, pain, cold, hot, etc, are felt by the skin.

Assess sensory awareness (e.g. cold from hot, dull from sharp, body part and joint sensation).

Although multiple studies have been conducted to study whether or not the vibrissal structures are sensitive to both outside disturbances as well as haptic touch, no conclusive evidence has been

This paper is an academic critique of an article written by Kirkland-Walsh, Teleten, Wilson, and Raingruber (2015) titled: Pressure mapping comparison of four OR surfaces. The authors sought to examine the results found from testing four different patient care surfaces commonly found in operating room suites. My analysis methodically focuses on specific aspects of the article relating to the process and research methods along with their associated results. While I think that the study itself is valid, I personally question if the volunteer population adequately and accurately represents an average surgical patient population in terms of health and comorbidities.

Multiple research teams have long worked on restoring touch to people with prosthetic limbs. So far the researchers at Stanford University were able to send signals to the brain tissue of mice, which closely mimicked the nerve messages of touch sensors in human skin, by creating electronic sensors. Another breakthrough happen two years ago, when researchers at Case Western Reaserch University in Cleveland, Ohio, gave people with prosthetic hands a sense of touch by wiring by wiring pressure sensors on the hands to perpheral nerves in their arms. Although, a rudimentary sense of touch has been restored with

Joanni appears to have intact vestibular processing. Joanni demonstrates inadequate proprioceptive and tactile awareness in the hands and fingers as evidence by his inability to appropriately latch his zipper or ability to manipulate other small objects when doing fine motor activities. Proprioception is the way receptors in our joints perceive muscle movements and it is important because those receptors allow us to coordinate movements. The Tactile system works through receptors in our skin which provide us with information about temperature, pressure, touch, and pain. One of the most important functions of the tactile system is to help alert us of danger in our environment A delay in processing this information may impact a person with fine

The first table contained the percentages of participants who detected two points on their forearms while the second table contained the percentages of participants who detected two points on their hands. At 0.0 cm, 2.86% of participants felt two points on their forearms while 8.57% felt them on their fingers. At 0.5 cm, 14.29% of participants felt two points on their forearms while 94.29% felt them on their fingers. At 1.0 cm, 20% of participants felt two points on their forearms while 97.14% felt them on their fingers. At 1.5 cm, 28.57% of participants felt two points on their forearms while 100% felt them on their fingers. At 3.0 cm, 85.71% of participants felt two points on their forearms while 100% felt them on their fingers. At 5.0 cm, 97.14% of participants felt two points on their forearms while 100% felt them on their fingers. This proves our hypothesis to be correct because the fingers of the participants were more sensitive than the forearm. The number of times a participant felt two points in the fingers increased with the distance between the calipers. This also happened when they were touched in the forearm, but the percentages were bigger in terms of the fingers because the fingers contain more sensory neurons than the

The Lab was performed by placing a piece of paper on a desk such that the edge of the paper was aligned with the edge of the desk. Next, the right-hand palm facing down with the third digit flexed such that it is perpendicular to the second and fourth digit was placed on the paper with the proximal aspect of the second and fourth phalanx aligned with the edge of the desk. Following the placement of the hand on the desk, the outline of the second and fourth digit was traced. The fingers were traced to the nearest fifth of millimeter. For accuracy, each finger was was measured three times and then the average of the three measurements was taken. The average ratio of the index finger to the ring finger was calculated by dividing the average length of the second digit by the length of the fourth digit. The measurements were then placed into an

Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system. This system is responsible for all the sensations we feel. Within the somatosensory system, there are four main types of receptors: mechanoreceptors, pain receptors, thermoreceptors, and proprioceptors. Mechanoreceptors decipher sensations such as pressure, vibrations, and texture. The thermoreceptors are responsible for perceiving the temperature of objects we touch. Pain receptors do exactly as they are named, they are responsible for detecting the feeling of pain. Finally, proprioceptors sense the position of the different parts of the body in relation to each other and the surrounding environment. When your hand touches an object, the mechanoreceptors in the skin are activated, and they start a chain of events by signaling to the nearest neuron that they touched something until the message reaches the brain, and causes a reaction (Pediaopolis

A report to investigate how the densities and thresholds of two different types of cutaneous receptors vary dependent on what part of the body tested Abstract The skin detects the modalities of touch and temperature through cutaneous receptors. The aim of this experiment was to examine the nature of these receptors and their distribution across the body. The results showed that out of the four skin areas examined, the greatest density of mechanoreceptors was on the tip of the finger.

I possess the skill to work under pressure. By that, I don’t mean to procrastinate on my responsibilities just because I can handle the situation well. Due to the nature of my job, I developed this skill and I still apply it on a regular basis. To be honest with you, I’m not planning to use it on my assignments because I think that will be an indication of not managing my time well. As far as attributes, I think that my perseverance has allowed me to get here. Because of the fact that English isn’t my first language, I couldn’t imagine enrolling in a graduate school since I immigrate to this country after 14 years

In lab we used a metal compass to measure and to find our two-point threshold acuity. When Dario was measuring my two-point sensitivity, I was blindfolded and had to judge whether or not I felt one-point or two-points. We tested these on multiple locations being, the pad of my index finger, pinky and thumb. We also measured our two-point sensitivity on the center of my palm, back of my hand and the top and bottom of my forearm. We took these measurements by starting the metal compass at 1mm for each location. The experimenter would incrementally increase the metal compass after each trial until the participant said they felt two points. The experimenter would then verify that measurement and would repeat the measurement once again for accuracy. My results for my two-point threshold sensitivity can be found on the table above. However, we found that the pads of my fingertips had the greatest number of receptive field. This didn’t surprise me because it makes sense to have a greater number of receptive fields in areas that are most predominantly used for touch. Something that did surprise me though was how few of receptive fields I had on my palm, back of my hand and on the top and bottom of my forearms. It makes sense that I’d have fewer receptive fields in this area because I don’t use this for touch usually but how few of receptive fields I had in these areas really surprised me. These measurements tell us that the number of receptive fields are predominantly

The touch detection features detection and each force can use or share some or all of the display area. For example, in one embodiment, a user can interact with an image displayed by touching and / or by applying a force in a proper position on the screen, with the corresponding position located anywhere on the screen. In another embodiment, the

According to Maria Montessori in her The Discovery of the Child, “Although the sense of touch is spread throughout the surface of the body, the Exercises given to the children are limited to the tips of the fingers, and particularly, to those of the right h and.” This allows the child to really focus on what he is feeling, through a concentration of a small part of his body. This can be achieving using the following materials/exercises;
