[Changes in the time required for a simple manual motor response in patients with cranio-cerebral injuries]

In 50 patients with craniocerebral injuries and 50 healthy subjects the duration of motor response of the right and the left hand to light stimulation was examined. It was found that the duration of this response depended on the injury gravity, the localization of the contusion focus in the brain, and the time that had passed since the injury infliction. The method described contributes to specifying the diagnosis of brain concussions and contusions; to determining the affected side of the brain, and to finding out whether the brain activity gets better or worse. In other words, the method offered is of a prognostic importance, and can be used in clinical nervous system function in craniocerebral injuries.
