Strong grip reflex

It is caused by the damage of the pre-exercise area. It is manifested by the involuntary groping of the contralateral upper limbs in the air. If you touch the palm of the patient's affected limb with an object, you often hold the contact object tightly and do not relax. Touching the palm of the hand with a blunt object showed positive flexion and gripping of the fingers, suggesting that the contralateral frontal lobe was damaged.
