“…Sensorimotor changes that occur after dry immersion include disturbed maintenance of vertical posture and a decline in the ability to withstand postural perturbations , disturbances in locomotor activity (Mel'nik et al 2006) and in the coordination and precision of movement (Grigor'eva and Kirenskaia et al 1985), disturbances in the control of eye movement, including pursuit function (Kornilova et al 2004(Kornilova et al , 2008 and gaze fixation (Kirenskaia et al 2006;Kreidich et al 1982;Tomilovskaya 2007;Tomilovskaya et al 2004Tomilovskaya et al , 2008.…”

Dry immersion, which is a ground-based model of prolonged conditions of microgravity, is widely used in Russia but is less well known elsewhere. Dry immersion involves immersing the subject in thermoneutral water covered with an elastic waterproof fabric. As a result, the immersed subject, who is freely suspended in the water mass, remains dry. For a relatively short duration, the model can faithfully reproduce most physiological effects of actual microgravity, including centralization of body fluids, support unloading, and hypokinesia. Unlike bed rest, dry immersion provides a unique opportunity to study the physiological effects of the lack of a supporting structure for the body (a phenomenon we call 'supportlessness'). In this review, we attempt to provide a detailed description of dry immersion. The main sections of the paper discuss the changes induced by long-term dry immersion in the neuromuscular and sensorimotor systems, fluid-electrolyte regulation, the cardiovascular system, metabolism, blood and immunity, respiration, and thermoregulation. The long-term effects of dry immersion are compared with those of bed rest and actual space flight. The actual and potential uses of dry immersion are discussed in the context of fundamental studies and applications for medical support during space flight and terrestrial health care.

“…First, the accuracy of movement control decreases (Repin, 1981; Kreidich et al, 1982; Grigorieva and Kozlovskaya, 1985; Kirenskaya et al, 1985; Sosnina et al, 2016). It has also been shown that the cortical organization of voluntary movements is changed (Kirenskaya et al, 2006; Tomilovskaya et al, 2008), and that the systems of posture and locomotion control suffer greatly (Melnik et al, 2006; Shpakov et al, 2008; Sayenko et al, 2016; Amirova et al, 2017). Similarly, studies of resting state brain activity revealed the changes similar to those obtained in a real space flight, indicating that support withdrawal is the main contributor to brain activity alterations and decline in the function of corticospinal tract function in weightlessness (Kuznetsova et al, 2015; Lazarev et al, 2018).…”

Dry Immersion as a Ground-Based Model of Microgravity Physiological Effects

et al. 2019

View full text Add to dashboard Cite

Dry immersion (DI) is one of the most widely used ground models of microgravity. DI accurately and rapidly reproduces most of physiological effects of short-term space flights. The model simulates such factors of space flight as lack of support, mechanical and axial unloading as well as physical inactivity. The current manuscript gathers the results of physiological studies performed from the time of the model’s development. This review describes the changes induced by DI of different duration (from few hours to 56 days) in the neuromuscular, sensory-motor, cardiorespiratory, digestive and excretory, and immune systems, as well as in the metabolism and hemodynamics. DI reproduces practically the full spectrum of changes in the body systems during the exposure to microgravity. The numerous publications from Russian researchers, which until present were mostly inaccessible for scientists from other countries are summarized in this work. These data demonstrated and validated DI as a ground-based model for simulation of physiological effects of weightlessness. The magnitude and rate of physiological changes during DI makes this method advantageous as compared with other ground-based microgravity models. The actual and potential uses of the model are discussed in the context of fundamental studies and applications for Earth medicine.

“…At the same time, there is a potential similar re-interpretation for the proprioception ( Roll et al, 2009 ). It was also shown that the cortical organization of voluntary movements undergoes changes ( Kirenskaya et al, 2006 ; Tomilovskaya et al, 2008 ), the systems of posture and locomotion control are severely affected ( Melnik et al, 2006 ; Shpakov et al, 2008 ; Sayenko et al, 2016 ; Amirova et al, 2017 ), and the accuracy of motion control decreases ( Sosnina et al, 2016 ). At present, little is known about the dynamic changes in the CNS caused by cerebrovascular changes that may be involved in the reorganization of the brain ( Kermorgant et al, 2020 ), however, during a 3-day DI, no significant changes in cerebral blood flow in the cerebral arteries were detected ( Ogoh et al, 2017 ).…”

Impact of different ground-based microgravity models on human sensorimotor system

et al. 2023

View full text Add to dashboard Cite

This review includes current and updated information about various ground-based microgravity models and their impact on the human sensorimotor system. All known models of microgravity are imperfect in a simulation of the physiological effects of microgravity but have their advantages and disadvantages. This review points out that understanding the role of gravity in motion control requires consideration of data from different environments and in various contexts. The compiled information can be helpful to researchers to effectively plan experiments using ground-based models of the effects of space flight, depending on the problem posed.
