Czyz with PEMS II

Wojtek Czyz uses the Percutaneous Electrical Muscle Stimulator (PEMS) from ESA to increase his muscle mass and reduce atrophy in the leg. PEMS was developed and manufactured by the Swiss company Syderal to prevent the effects of microgravity on astronauts particularly muscle atrophy and accompanying effects like bone mineralization and cardiovascular de-conditioning. In 1996 PEMS I flew on the Space Shuttle and PEMS II is planned to be delivered to the ISS next May.
