Action Observation Theraphy in Severe Acquired Brain Injury.

Using a 13-inch tablet, the patient will be shown, from a third-person lateral perspective framing the palmar side of the hand, a video that repeatedly plays a simple movement of daily life (grasping a glass on the table with the hand and bringing it closer to oneself) for 5 consecutive minutes. The video should be customized based on the side being treated (ex: right hemiparesis, video framing a right hand). After 1 minute of rest, the therapist will ask the patient to perform the newly observed movement for a minimum duration of 2 minutes and a maximum of 5 minutes. The cycle will be repeated a total of 3 times, for total treatment time between 25 and 35 minutes per session.

Conventional treatment will focus on joint mobilization, muscle stretching, and neuromuscular facilitation activities, using the main rehabilitation methods (e.g., neurocognitive theory, Bobath Concept, Progressive Neuromuscular Facilitation, etc.).
