Craniocerebral Trauma | Effect of Passive Gait Training on the Cortical Activity in Patients With Severe Brain Injury.
Craniocerebral Trauma research study
What is the primary objective of this study?
The aim of this study is to determine effect of proprioceptive stimulation with passive gait training on the cortical activity in patients with severe brain injury, demonstrated as changes in EEG (electroencephalogram)and ERP (Event Related Potentials). Hypotheses: 1) Proprioceptive stimulation increases EEG-frequency in patients with impaired consciousness due to severe brain injury. 2) Proprioceptive stimulation increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe brain injury.

Tilt table contraindications: orthostatic circulatory problems, unstable fractures, severe osteoporosis, sken problems, joint problems, severe asymmetry (major difference in leg length over 2 cm), co-operation problems (psychotic illnesses or neurotic disturbances), adjustment problems (i.e. integrated stepping system cannot be safely adjusted to the patient)
Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Traumatic Brain Injury
Anoxic Brain Injury
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Behavioral:Tilt Table With Integrated Stepping SystemPassive Gait Training: one session, 20 minutes, table tilted to 70-80 degrees, speed 60 steps per minute.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
