“…Apart from vertigo, the treatment on the swing was followed by "the most refreshing slumbers" (Cox, 1806, p. 140), a characteristic which he considered highly valuable to cure his patients. Interestingly, subjective drowsiness is nowadays listed as a cardinal symptom of motion sickness as well as the so-called "sopite syndrome", a reaction in response to prolonged motion (Graybiel, 1969;Graybiel and Knepton, 1976;Guedry and Graybiel, 1961;Lawson and Mead, 1998), which matches Cox's observations of patients' becoming sleepy after having experienced his treatment.…”

Although the discovery and understanding of the function of the vestibular system date back only to the 19th century, strategies that involve vestibular stimulation were used long before to calm, soothe and even cure people. While such stimulation was classically achieved with various motion devices, like Cox's chair or Hallaran's swing, the development of caloric and galvanic vestibular stimulation has opened up new possibilities in the 20th century. With the increasing knowledge and recognition of vestibular contributions to various perceptual, motor, cognitive, and emotional processes, vestibular stimulation has been suggested as a powerful and non-invasive treatment for a range of psychiatric, neurological and neurodevelopmental conditions. Yet, the therapeutic interventions were, and still are, often not hypothesis-driven as broader theories remain scarce and underlying neurophysiological mechanisms are often vague. We aim to critically review the literature on vestibular stimulation as a form of therapy in various selected disorders and present its successes, expectations, and drawbacks from a historical perspective.

“…The findings of the Marco Polo Mission, that is the fact that the maximum voluntary contraction (MVC) was decreasing during the first period followed by recovery in the last days was confirmed by the same astronauts during the Eneide Mission (Soyuz 10S, April 15 to April 24,2005) and then during the Esperia Mission (STS 120, October 23 to November 7, 2007, our unpublished data). The observed astronauts' MVC behavior resembled the one shown by people affected by the sopite syndrome, a neurological disorder triggered by prolonged periods of motion that relates to symptoms of drowsiness, fatigue, and mood changes [7].…”

The study and analysis of human physiology during short-and long-duration space flights are the most valuable approach in order to evaluate the effect of microgravity on the human body and to develop possible countermeasures in prevision of future exploratory missions and Mars expeditions. Hand performances such as force output and manipulation capacity are fundamental for astronauts' intra-and extravehicular activities. Previous studies on upper limb conducted on astronauts during short-term missions (10 days) indicated a temporary partial reduction in the handgrip maximum voluntary contraction (MVC) followed by a prompt recovery and adaptation to weightlessness during the last days of the mission. In the present study, we report on the "Crew's Health: Investigation on Reduced Operability" (CHIRO) protocol, developed for handgrip and pinch force investigations, performed during the six months increment 7 and increment 8 (2003-2004) onboard International Space Station (ISS). We found that handgrip and pinch force performance are reduced during long-term increments in space and are not followed by adaptation during the mission, as conversely reported during short-term increment experiments. The application of protocols developed in space will be eligible to astronauts during long-term space missions and to patients affected by muscle atrophy diseases or nervous system injury on Earth.

“…However, Figure 1 leads to the conclusion that SD is the only significant means by which acceleration stimuli to the vestibular organs can disrupt human well-being and trigger LSA. This is unlikely, since acceleration stimuli to the vestibular organs probably influence attentional resources, and hence, SA (Graybiel & Knepton, 1976;Lawson & Mead, 1998). While SD is probably the most important way in which vestibular stimuli give rise to LSA and human error during flight, the authors believe it would be a mistake to conclude that SD is the only way that acceleration stimuli to the vestibular organs contribute to LSA and human error.…”

“…Numeral 2 of Figure 3 shows that SD might be identified as a contributor to a human error (leading to a mishap) without LSA also being implicated, as one can infer (personal communication, Previc, 2002) happens in 7 of the SD-only mishaps that remain when one subtracts the 263 LSA mishaps from the 270 combined SD/LSA mishaps shown in Table 1 of Gillingham, 1992 (See Table 1 of this paper). Numeral 3 in Figure 3 represents the sopite syndrome (Graybiel & Knepton, 1976;Lawson & Mead, 1998), shown in this case as intersecting with attentional problems, LSA, and human error). Figure 3 allows for combined visual and vestibular effects to be produced without causing LSA or human error, as might occur upon changing one's glasses prescription, wherein subtle changes in one's vestibulo-ocular reflex may take place.…”

“…Studies in various motion settings suggest that vestibular stimuli cause changes in cognitive or affective state (Lawson & Mead, 1998) that should affect SA adversely. Even mild and non-sickening vehicle motions have been associated with relaxation, drowsiness, fatigue, decreased concentration, and decreased motivation (Lawson, Kass, Muth, Sommers, & Guzy, 2001).…”
