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.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Craniocerebral Trauma

Traumatic Brain Injury

Subarachnoid Hemorrhage

Anoxic Brain Injury

Study Interventions

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.

Study Arms

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.
