Reportage in a rehabilitation centre in Germany, specialising in neurological rehabilitation after a stroke or head injury. The centre is equipped with a number of robotic technologies which facilitate exercises. A patient who is paralysed in both legs practices walking again using the Lokomat. The Lokomat is made up of two orthopedic braces which are strapped to the patient's lower limbs, an unloading system allowing the patient to be relieved of some of their weight, and a treadmill which allows the movements of walking to be reproduced.
