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 Motion Sickness by : Thomas G. Dobie
Download or read book Motion Sickness written by Thomas G. Dobie and published by Springer. This book was released on 2019-02-01 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a survey of the state of the art in the field of motion sickness. It begins by describing the historical background and the current definition of motion sickness, then discusses the prevalence among individuals, along with the physiological and psychological concomitants of the disorder. It reviews the incidence of motion sickness in numerous provocative motion environments and discusses various personal factors that appear to influence this aspect. Various characteristics of provocative motion stimuli are also described, together with the results of studies conducted in the laboratory, on motion simulators and at sea. Laboratory tests that could potentially be used to assess an individual’s susceptibility to motion sickness and his or her ability to adapt to motion environments are presented in detail, together with the ways in which individuals might be trained to prevent motion sickness or more effectively cope with motion environments. In closing, the book reports on the cognitive-behavioral approach developed by the author (Dobie, 1963) as well as the various desensitization programs employed in military settings, and discusses the relative effectiveness of these methods in comparison to cognitive-behavioral counseling.
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 Motion Sickness Produced by Head Movement as a Function of Rotational Velocity by : Earl F. Miller (II)
Download or read book Motion Sickness Produced by Head Movement as a Function of Rotational Velocity written by Earl F. Miller (II) and published by . This book was released on 1970 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: To measure the stressor stimulus effect of rotational velocity in terms of the number of the standardized head tilt movements required to evoke a common severity level of symptoms characterizing motion sickness, sixteen young healthy subjects were rotated in a laboratory (Stille) rotational chair at various velocities within a range suitable for each subject and the limits of 1.0 to 30.0 rpm. Standardized 90 degree head movements were executed at each test velocity until the preselected and quantitatively determined motion sickness endpoint of moderate (M IIA) or severe (M III) malaise was reached. When individual ability to make head movements without evoking symptoms was exceeded, the derived average stressor effect (E factor) of each head movement varied directly and, in log-log terms, linearly with rotational velocity. These data provide the basis for grading individual susceptibility to Coriolis (motion) sickness with a single numerical score as well as define the high rate of change of Coriolis stressor effect as a function of rotational velocity, which may find practical application for specifying rotational rates of space stations.

Book Synopsis Motion Sickness Susceptibility Under Weightless and Hypergravity Conditions Generated by Parabolic Flight by : Earl F. Miller (II)
Download or read book Motion Sickness Susceptibility Under Weightless and Hypergravity Conditions Generated by Parabolic Flight written by Earl F. Miller (II) and published by . This book was released on 1969 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Motion sickness susceptibility of five labyrinthine-defective (L-D) and 25 normal subjects was tested under the force environments encountered in parabolic flight (0 g and hyper-g). The L-D subjects were uniformly symptomless, while the normal subjects revealed great inter- and intra-individual differences in susceptibility to motion sickness provoked by standardized head movements during: (1) the hypergravic and (2) the weightless phases of the parabolic maneuver while restrained; and (3) the weightless phase while being rotated in a chair. Four of six subjects tested under condition 1 were completely unaffected by the condition while two reacted with symptoms. Condition 2 provoked severe symptoms in five of the twelve subjects tested and moderate symptoms in one. Fifteen subjects tested under condition 3 revealed either a marked increase or decrease in susceptibility to Coriolis acceleration in weightlessness compared to terrestrial baseline measurements.
