After a brain hemorrhage coma, the hand may move as a normal phenomenon of hypertonia of the muscles, or it may be a primitive reflex or a sign of improvement of the condition.
1. Excessive muscle tone: after the patient falls into coma with brain hemorrhage, if the muscle tone of the muscles innervating the hand is too high, the muscles will contract, which will lead to the movement of the hand, but this movement usually does not have any significance.
2. Primitive reflexes: if the amount of cerebral hemorrhage is relatively large and the damage to the brain is relatively serious, the inhibitory effect of the cerebral cortex on the primitive reflexes is weakened or disappeared, and primitive reflexes, such as the strong grip reflex, groping reflex, etc., may appear on the hands of the patients.
3. Improvement of condition: If the hands of a patient with cerebral hemorrhage show movement after coma, it may be a sign that the condition has stabilized and gradually improved.
There may also be other reasons for the hand movements of patients with cerebral hemorrhage after coma. It is recommended that the patient should consult a doctor in time, and the doctor will make a judgment according to the degree of the patient’s condition.
