Brief Summary: The aim of this study is to determine whether passive gait training increases arousal demonstrated as changes in EEG electroencephalogram activity

Hypotheses 1 Passive gait training increases EEG-frequency in patients with impaired consciousness due to severe traumatic brain injury

2 Passive gait training increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe traumatic brain injury
Detailed Description: Severe traumatic brain injury especially after a high energy trauma is characterised with focal lesions and diffuse axonal injury which leads to the dysfunction in the cortico-spinal cortico- cortical connections and reticular activation system Formatio reticularis plays an important role in arousal Tactile and proprioceptive stimulation with a view to improving level of consciousness in coma patients is popular in the western world despite insufficient evidence of its effectiveness Affolter-Bobath-Coombes-concept is the most commonly used tool in the rehabilitation of brain damaged patients This concept is based on the theory that tactile proprioceptive and oral stimulation develops new connections in the brain and thereby stimulates consciousness and behaviour Elliot et al shows improvement in level of consciousness due to postural changes from a lying position to a standing posture in 8 of 12 patients using Wessex Head Injury Matrix

Passive movements result in proprioceptive stimulation the effect of which is close to that achieved by physiological voluntary activity PET and fMRI studies show that passive movements activate several areas in the motor cortex

In order to increase afferent cortical input passive gait training in the body weight support robotic gait orthosis could be used in patients with impaired consciousness inability to cooperate and poor balance This device gives the possibility to establish therapeutically correct upright body position and passive legs movement simultaneously

To our knowledge there are no studies which illustrate the effects of passive gait training on cortical activity in patients with impaired consciousness due to severe traumatic brain injury

Our hypothesis is that passive gait training of this group of patients increases arousal which can be shown in an increased EEG electroencephalogram-frequency and increased conductivity speed of the cognitive P300-component of ERP Event Related Potentials

Comparisons EEG- and ERP-activity after a single training session in robotic gait orthosis in patients with severe traumatic brain injury compared to EEG- and ERP-activity after a single training session in robotic gait orthosis in healthy persons
