Several studies underline the importance of early mobilization of patients with brain injuries, leading to shorter hospital stays, less contractures, and improved general function.~The routine mobilization treatment in the rehabilitation of patients with severe brain injuries in Sunnaas Rehabilitation Hospital is initial use of a tilt table where tilt angle is gradually increased, and when tolerated, standing in a classic standing frame where the patient's lower body is fixed to the device in an upright standing position.~Innowalk Pro is a robotic standing device where legs are fixed, but passively moved by electric motors in an upright standing position. An assumption is that standing in Innowalk Pro might be better tolerated at an earlier stage of rehabilitation than standing in a classic standing frame.
This study will explore physical and physiological responses to mobilization of patients with acquired brain injuries in subacute phase using a classic standing frame and a standing device with simultaneous passive movement of legs, Innowalk Pro.
