Available in PDF, EPUB and Kindle. Book excerpt: A slow rotation room in a laboratory environment provides an excellent instrument for the study of motion sickness because the experimenter can control not only the stressful Coriolis accelerations, but also other important procedural and environmental variables. By exploiting this control, combined with the judicious selection of experimental subjects, it was possible to confirm many previous findings and demonstrate that manifestations of disturbances in the vestibular system fall into two distinct categories. In the first category are reflex phenomena evoked by Coriolis accelerations when the head is rotated out of the plane of the room's rotation, and revealed through systems which, under natural stimulus conditions, have functional articulations with vestibular receiving areas. The symptomatology in the second category comprises an epiphenomenon superimposed on any manifestation of the first, when the unusual vestibular activity, presumably through facilitory-inhibitory processes, irradiates to cells or cell assemblies not normally stimulated. Selected experimental findings are used in defining the characteristics of manifestations in the two categories and in demonstrating the nature of the facultative linkage between the otherwise independent systems underlying manifestations in the two categories.

Book Synopsis Motion and Space Sickness by : George H. Crampton
Download or read book Motion and Space Sickness written by George H. Crampton and published by CRC Press. This book was released on 1990-01-17 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compendium, written by active researchers in the field, encompasses topics ranging from anatomical and physiological subjects, through analyses of stimulus characteristics, prediction of sickness, and consideration of human factors, to pharmacological and behavioral therapeutic measures for terrestrial as well as microgravity travelers. Material often found scattered in diverse journals, paper-bound proceedings of symposia, difficult-to-find laboratory reports, or included with other topics in collections having a diffuse focus, are presented here in one volume dedicated to a single theme. The critical up-to-date- reviews are a first source for researchers and research program managers as well as an essential information source for engineers and practitioners.
Book Synopsis A Standardized Laboratory Means of Determining Susceptibility to Coriolis (motion) Sickness by : Earl F. Miller (II)
Download or read book A Standardized Laboratory Means of Determining Susceptibility to Coriolis (motion) Sickness written by Earl F. Miller (II) and published by . This book was released on 1969 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A standard method developed for quantifying Coriolis (motion) sickness susceptibility was evaluated in 250 normal and three labyrinthine-defective subjects. The procedure required the subject to execute standard head movements (plus or minus 90 degrees in the frontal and sagittal planes) while seated in a chair device that was rotated at one of several constant velocities. The proper test velocity was predicted in the majority of cases with the Motion Experience Questionnaire. Three of the normal and all of the labyrinthine-defective subjects were found to be unsusceptible to these test conditions. Coriolis Sickness Susceptibility Index, CSSI, was determined for each subject by multiplying the appropriate E factor, the average stress effect of each head movement for the rpm used in the test, by the number of head movements required to provoke severe malaise (M III). The resultant CSSI values for the 250 subjects ranged from 0.4 to 100, but the distribution was markedly rigt skewed. The procedure yielded a high test-retest reliability (p = .89) in terms of CSSI scores and pattern of symptomatology. In reaching the Malaise III level, the nausea syndrome was manifested in most cases, but a significant percentage (9.6%) of the subjects remained free of any epigastric disturbance or nausea.

Book Synopsis Changes in Subjective Estimates of Well-being During the Onset and Remission of Motion Sickness Symptomatology in the Slow Rotation Room by : James T. Reason
Download or read book Changes in Subjective Estimates of Well-being During the Onset and Remission of Motion Sickness Symptomatology in the Slow Rotation Room written by James T. Reason and published by . This book was released on 1969 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The onset of motion sickness is characterized by a decline in generalized feelings of well-being. In this study, an attempt was made to quantify these subjective changes during the experimental production of motion sickness in the Slow Rotation Room. A simple eleven-point rating scale was used to measure the well-being state. The nature and the time of onset of symptoms were recorded independently. Systematic relationships were obtained between the amount of stimulation required to produce the Malaise 111 endpoint and the rate of change of well-being. In general, relatively susceptible individuals showed on immediate decline in well-being at the onset of the stimulus which continued to fall sharply until the endpoint was reached. With increasing resistance to motion sickness, this point of rapid decline ('avalanche phenomenon') was proportionately delayed. The point on the rating scale at which this rapid decline began was relatively consistent across all subjects. Various positions along the well-being scale were consistently associated with specific constellations of symptoms. The recovery of well-being, following the cessation of the stimulus, appeared to be slower in individuals of low susceptibility than in those who were highly susceptible. (Author).
Book Synopsis Histamine Intolerance by : Reinhart Jarisch
Download or read book Histamine Intolerance written by Reinhart Jarisch and published by Springer. This book was released on 2014-11-10 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Histamine is an important mediator of allergic diseases, but knowledge of histamine as a cause of numerous non-allergic symptoms and signs is limited. This book offers wide-ranging coverage of histamine intolerance. There is extensive background discussion of the origin of histamine, its content in food and alcoholic beverages and intolerance to red wine. Diagnosis of histamine intolerance is explained and the various symptoms of histamine intolerance are clearly described. Subsequent chapters cover the relation of histamine to a wide variety of conditions, including drug intolerance, atopic dermatitis, seasickness and osteoporosis. This book will prove of value in clinical practice by facilitating differential diagnosis, which is by no means straightforward given the multiplicity of symptoms of histamine intolerance and by assisting in the selection of therapeutic measures.
