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 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 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.

Book Synopsis Susceptibility to Acute Motion Sickness in Blind Persons by : Ashton Graybiel
Download or read book Susceptibility to Acute Motion Sickness in Blind Persons written by Ashton Graybiel and published by . This book was released on 1970 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A group of twelve persons selected only on the basis of their visual defects were exposed to stressful Coriolis accelerations under standardized conditions. All demonstrated differences in susceptibility to acute motion sickness that bore no relation to their rank order of visual deprivation. Insofar as comparison with a group of normal subjects was made possible, no significant differences in susceptibility were demonstrable. It was concluded that vision is not an essential but rather a secondary etiologic factor in the genesis of motion sickness. This is not incompatible with the fact that symptoms characteristic of motion sickness may be visually induced in the absence of 'motion.' (Author).
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.
