Introduction[edit | edit source]
Physiotherapy continues to expand horizons and physiotherapy in space is one such example. When exposed to microgravity , the astronauts experience physiological changes similar to detraining athletes or senile bedridden patients. A physiotherapist works with a sports scientist and prepares and conditions the astronaut for the space flight and reconditions the astronaut after their return. The role of physiotherapy begins with aiding the pre flight stress relief, counteracting in-flight symptoms , design a well curated exercise regime during the space station stay.[1]
Adaptions of human body to microgravity[edit | edit source]
The physiological adaptations of the human body depends on the duration of the flight. The space flight can be a short space flight which ranges from one day to 14 days whereas long space flight is up to 14 days. The physiological adaptations occur because of two major factors : 1) reduced hydrostatic gradient 2) reduced ground reaction force. These factors leads to unloading and disuse of weightbearing structures[2].
Cardiovascular system adaptations[edit | edit source]
As the hydrostatic gradient reduces , there is an upward shift of the blood and fluids in the thoraco-cephalic region and there is shift of the fluid from the extracellular space to intracellular space leading to puffy face. The total cardiac work reduces. When the astronaut is continuously exposed to microgravity the volume of the left ventricle reduces. There is evidence of cardiac atrophy on magnetic resonance imaging resulting from prolong exposure to microgravity. It has been found that while returning to earth there is reduction in orthostatic tension which results in postural hypotension while returning to the earth.
