Myotones: measuring muscle tone in microgravity conditions
For the purposes of the Myotones experiment, MyotonPRO is monitoring the basic biomechanical properties of the musculoskeletal system of astronauts in space for the very first time. As a smartphone-sized wearable device, it can study changes caused by the lack of gravity to the musculature of astronauts on board the ISS, in a simple and non-invasive way. On 19 June 2018, Alexander Gerst became the first astronaut to determine his muscle status objectively, quickly and easily in space.
