Heart Rate Variability (HRV) reflects the responsiveness of the autonomic system to an external stimuli. The aim of this system is to maintain homeostasis.The variability implies on the interaction between the sympathetic and the parasympathetic systems to maintain the ongoing changes of the autonomic system. Following Acquired Brain Injury (ABI), there can be a damage to the Central Nervous System (CNS) function. The damages described in the literature are cognitive, motor and behavioural function, while there is less relation to the autonomic system. The autonomic system can influence the ability of patient with ABI to participate in the rehabilitation program. The aim of this work is to investigate the activity of the autonomic system activity as manifested by HRV among patients with ABI in different conditions: resting, during activity and while listening to different auditory stimuli.

| Heart Rate Variability | Heart Rate Variability as measured by HOLTER EKG during the 4 different conditions: first measuerement 2-8 weeks from hospitalization in the TBI rehabilitation department-24 hours detection for HRV baseline. Second measurement: a week after: EKG during the 4 conditions. Third measurement:a month after the first measure, Fourth measurement: 2 months after the first one. Last measurement: Before the release home from rehabilitation (up to one year from the first measurement). | first measurement: 2 weeks to 2 months from hospitalization to the department: 24 hours EKG follow up for HRV base line. Last measurement: before the release from rehabilitation (up to 12 months). |
