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.

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.

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.
