10 patients of the CF Center Cologne, Germany, took part in the Galileo study. They were provided by the vibrating platform (Galileo 2000)for whole body vibration training at home. The patients were standing in an upright position receiving vertical vibration of frequencies between 20-25 Hz. This vibration exercise evokes muscle contractions via stretch reflexes improving muscular activity. The training schedule consisted of three 3-minute sessions twice a day 5 days per week for 3 months.
