Sports therapist Stefan Köhler is the man behind the machine. He is a specially trained EKSO therapist and is able to combine his interest in technology with working with people at the Robotics Centre. He is most often found using the exoskeleton, a mobile support corset that is attached to a patient’s trunk and legs. He sets up the EKSO GT gait robot from EKSO-Bionics, then walks behind the patient during therapy and stabilises them if necessary. Without the device, as many as three strong assistants could be needed in order to support the patient’s body. Thanks to the device, the patient and therapist can move around the room entirely freely.
