Inverted Binocular Phenomenon
Disowning Pain Phenomenon (or "Inverted binocular phenomenon") is the subject of a 2008 study which suggested that distorting the body image can change the way people sense how it feels. For example, when a person sees an organ through inverted binoculars, it looks smaller than it really is, which may reduce the pain connected to that organ. Ten patients with persistent discomfort in their right arms that was exacerbated by movement were instructed to move their arms while their visual impressions of those arms were adjusted. They first used binoculars to magnify how their bodies appeared, then switched to inverted binoculars to lessen the size of the image. They were also asked to rate the level of pain they felt while viewing the image. The more limbs that developed, the greater pain was felt. Binocular magnifying and minimizing can even modify the extent of edema Edema (American English), also spelled oedema (British English), and also known as fluid retention, swelling, dr ...

Body Image
Body image is a person's thoughts, feelings and perception of the aesthetics or sexual attractiveness of their own body. The concept of body image is used in several disciplines, including neuroscience, psychology, medicine, psychiatry, psychoanalysis, philosophy, cultural and feminist studies; the media also often uses the term. Across these disciplines, there is no single consensus definition, but broadly speaking, body image consists of the ways people view themselves; their memories, experiences, assumptions, and comparisons about their appearances; and their overall attitudes towards their respective heights, shapes, and weights—all of which are shaped by prevalent social and cultural ideals. Body image can be negative ("body negativity"), positive (" body positivity") or neutral in character. A person with a negative body image may feel self-conscious or ashamed and may feel that others are more attractive. In a time where social media holds a very important place and ...

Binoculars
Binoculars or field glasses are two refracting telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most binoculars are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal-mounted military models. Unlike a (monocular) telescope, binoculars give users a stereopsis, three-dimensional image: each eyepiece presents a slightly different image to each of the viewer's eyes and the parallax allows the visual cortex to generate an depth perception, impression of depth. Optical design evolution Galilean Almost from the invention of the telescope in the 17th century the advantages of mounting two of them side by side for binocular vision seems to have been explored. Most early binoculars used Galilean telescope, Galilean optics; that is, they used a convex lens, convex objective (optics), objective and a concave lens, concave eyepi ...

Edema
Edema (American English), also spelled oedema (British English), and also known as fluid retention, swelling, dropsy and hydropsy, is the build-up of fluid in the body's tissue (biology), tissue. Most commonly, the legs or arms are affected. Symptoms may include skin that feels tight, the area feeling heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include Chronic venous insufficiency, venous insufficiency, heart failure, kidney problems, hypoalbuminemia, low protein levels, liver problems, deep vein thrombosis, infections, kwashiorkor, angioedema, certain medications, and lymphedema. It may also occur in immobile patients (stroke, spinal cord injury, aging), or with temporary immobility such as prolonged sitting or standing, and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involve ...

Body Shape
Human body shape is a complex phenomenon with sophisticated detail and function. The general shape or figure of a person is defined mainly by the molding of skeletal structures, as well as the distribution of muscles and adipose tissue, fat. Skeletal structure grows and changes only up to the point at which a human reaches adulthood and remains essentially the same for the rest of their life. Growth is usually completed between the ages of 13 and 18, at which time the epiphyseal plates of long bones close, allowing no further growth (see Human skeleton). Many aspects of body shape vary with gender and the female body shape especially has a complicated cultural history. The science of measuring and assessing body shape is called anthropometry. Physiology During puberty, Virilization, differentiation of the male and female body occurs for the purpose of reproduction. In adult humans, muscle mass may change due to exercise, and fat distribution may change due to Sex hormones, hor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
