Book Synopsis Diagnostic Criteria for Grading the Severity of Acute Motion Sickness by : Ashton Graybiel
Download or read book Diagnostic Criteria for Grading the Severity of Acute Motion Sickness written by Ashton Graybiel and published by . This book was released on 1968 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: New diagnostic criteria are presented for grading the severity of acute motion sickness. They are more suited to clinical application as empirical evaluations than for precise measurement of physiological functions. The new criteria differ from the old in two important respects: (1) 'moderate malaise, ' previously defined on an exclusion basis, has been divided into two categories and precisely defined, and (2) numerical scoring is optional. By holding fast to the definition of endpoints in the 'old' criteria with proven reliability and validity, the change does not seriously affect the findings in experiments where the old criteria were used.

Book Synopsis Comparison of Five Levels of Motion Sickness Severity as the Basis for Grading Susceptibility by : Earl F. Miller (II)
Download or read book Comparison of Five Levels of Motion Sickness Severity as the Basis for Grading Susceptibility written by Earl F. Miller (II) and published by . This book was released on 1970 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Coriolis (motion) sickness susceptibility index (CSSI) of 275 healthy male subjects was calculated from data obtained by a standardized laboratory procedure at each of five specific levels of motion sickness severity, viz, frank sickness (FS), severe malaise (M III), moderate malaise (M IIA and M IIB), and mild malaise (M I). The stressor value (E factor) of a single standardized head movement associated with each rotational rate of the test chair was adjusted to yield an equivalent CSSI score independent of the endpoint selected. Close agreement among the CSSI scores obtained at each endpoint was found in intercorrelations, test-retest reliability coefficients (N = 30), and frequency distributions that reflected the orderliness and stability in the appearance, ramification, and intensification of the acute symptomatology evoked in progressing from M I to FS. The endpoint M IIA appeared, however, to yield the best balance between subject acceptability and test confidence, and was used without exception to calibrate the motion sickness susceptibility of 250 additional subjects.

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.

Download or read book Virtual and Adaptive Environments written by Lawrence J. Hettinger and published by CRC Press. This book was released on 2003-06-01 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: With contributions from a collection of authors consisting of many recognizable experts in the field of virtual and adaptive environments, as well as many up and coming young researchers, this book illustrates the many ways in which psychological science contributes to and benefits from the increased development and application of these nascent systems. Discussing issues from both a user- and technology-based standpoint, the volume examins the use of human perception, cognition, and behavior. The book builds a foundation on the assumption that these systems are first and foremost human-centered technologies, in that their purpose is to complement and extend human capabilities across a wide variety of domains.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an overview of neuroscience research performed in space since the observations made during the first manned space flights to the detailed scientific investigations currently being carried out onboard the International Space Station. This book is for the general scientific reader. Each project and the reason why it was done is described with illustrations, rationale and hypothesis, and a summary of results. Also, reference lists guide readers to the published papers from experiments. This book is a legacy of what we have learned on brain mechanisms and functions through research done in space, and a guide for what could be investigated in the future.

Book Synopsis Vestibular Function on Earth and in Space by : J. Stahle
Download or read book Vestibular Function on Earth and in Space written by J. Stahle and published by Elsevier. This book was released on 2013-10-22 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wenner-Gren Center International Symposium Series, Volume 15: Vestibular Function on Earth and in Space provides information pertinent to the fundamental aspects of vestibular research. This book discusses the problems concerned with space, with emphasis on the importance of the vestibular apparatus in space flight. Organized into 32 chapters, this volume begins with an overview of the mechanisms and processes for creating the chemical composition of endolymph. This text then examines the speculative comparisons between prolonged exposure in a manne weightless space station and in a rotating space station. Other chapters consider the relationships between vestibular nystagmus and degradation of visual acuity when the vestibular stimuli interfere with voluntary efforts to see specific visual detail. This book discusses as well the concepts concerning the distribution of function between semicircular canals and otolith organs. The final chapter deals with the method for selective marking of neurons after axonal transection. This book is a valuable resource for otologists and scientists.
Book Synopsis Evaluation of Antimotion Sickness Drugs: a New Effective Remedy Revealed by : Charles D. Wood
Download or read book Evaluation of Antimotion Sickness Drugs: a New Effective Remedy Revealed written by Charles D. Wood and published by . This book was released on 1970 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three single drugs (one used in three dosage levels) and three drug combinations were compared in their effectiveness to prevent motion sickness under standarized stress conditions in a slow rotation room. An unexpected finding was that a combination of promethazine 25 mg with d-amphetamine 10 mg had the same range of effectiveness as that found in earlier studies (and confirmed here) for scopolamine 0.6 mg plus d-amphetamine 10 mg. When scopolamine was tested alone, halving the 'usual' dose (0.6 mg) reduced its effectiveness about one-fifth and doubling the usual dose increased effectiveness by 29 per cent; thus, the optimum dose of scopolamine appeared to be approximately 0.5 mg. Betahistine hydrochloride (4 mg) was ineffective and cinnarizine (50 mg) was of small benefit. (Author).
