Rolfing is a bodywork technique that involves deep manipulation of the fascia and soft tissue to improve body alignment and balance. Rolfing was named after its creator, Dr. Ida Rolf (1896–1979), who more than 50 years ago recognized that the body is a system of networks of tissue rather than a collection of separate parts. The Rolfing process enables the body to regain the natural integrity of its form, thus enhancing muscular and postural efficiency and freedom of movement. It has also been shown to significantly reduce chronic stress and reduce spinal curvature in individuals with swayback (lordosis). However, because Rolfing is a deep-tissue approach and usually involves a series of treatments, it may be painful for women who are sensitive to pressure.
Problems on Deficiency and Excess of Minerals In Animal Nutrition

Two major forms of copper deficiency are seen in sheep, namely, enzootic ataxia or “sway back” and “ill-thrift”, both forms occurring in lambs. Swayback is seen particularly in infant lambs from ewes which have received an inadequate supply of copper during pregnancy. This is the most common type of copper deficiency in sheep in, inter alia, Great Britain.50 The disease may occur in a congenital form in which lambs exhibit incoordination or ataxia at birth. They have difficulty in standing or moving about and often die of starvation or secondary infections. Swayback also occurs in a delayed form in which the newborn lambs appear to be normal, only to develop incoordination, especially of the hindquarters (hence, the name) after a few weeks. Swayback is associated with characteristic pathological changes in the central nervous system due to defective myelin formation caused by failure of the enzyme cytochrome oxidase.

Subsequently, no reasonable explanation has been established for this puzzling group of cases. It is even more puzzling when one considers that swayback itself is considered to be linked with copper deficiency and is not thought to have an infective aetiology. Campbell et al. (1950) also reported six patients with M.S. all living within the same small village. Millar (1966) described two high risk areas in Northern Ireland; one containing seven patients in a population of 1000 and the other seven in a population of 500. In the only formal statistical analysis involving M.S. patients, however, no evidence of clustering was found by the methods used (Ashitey and MacKenzie, 1970; Hargreaves and Merrington, 1973).
The stereoscopic phenomena in relation to the doctrine of identical retinal points
Published in Strabismus, 2020
Ernst Wilhelm von, Brücke 3 remarks that we never see an object in its totality, but only one point of it completely clearly, namely the point at which the axes of the eyes cross. In order to obtain a clear image of the object, we fixate the various points of it in the sequence of time, and with the movements of the eyes which are necessary for this, the visual range (translator: state of convergence] undergoes an incessant change. Such changes in the range of vision are necessary because the various points of an object that we are looking at really lie at different distances from the eye and require a different adjustment of the axes of vision in order not to be seen double. In these changes of the visual range, we run through a continuous series of horopters, so that when the visual range has gone through all changes from the horopter for the most distant of the points visible to us on the object to the next and, accordingly, all of the points of the object have once fallen into the horopter with the continuous change of the images on the retinas all points of the object visible to the observer will be depicted once on identical places of the retina. According to Brücke, the parts of the image which fall on identical retinal points would produce an incomparably more vivid and lasting impression than the parts of the image which fall on different points and appear double. The part of the image that falls on identical retinal points and therefore appears single, gets prevalence over the double images that exist at the same time, because, as a result of a subjective urge, we look for the single and avoid the double. Hence the eyes which ceaselessly, although unconsciously, sway back and forth between the horopter for the most distant and that for the closest point, give the impression of a single object and an object expanding in three dimensions of space.
