After his return to Earth from his first expedition to the International Space Station, ESA astronaut Matthias Maurer began a re-adaptation programme lasting several weeks, like all astronauts after spaceflight. It includes medical examinations, physical exercise and follow-up examinations and experiments.
He posted this image to his social media channels on 23 May 2022 with the caption:
"A range of different standard measurements (cardiovascular, motor, cognitive, etc.) are carried out on all astronauts before, during and after their missions to the International Space Station to better understand the typical risks involved in crewed spaceflight. The "Standard Measures Carotid Intima-media Thickness Test" (CIMT) you can see in this picture determines the effects of microgravity on my cardiovascular system by measuring my blood pressure and thickening of my arterial walls."
