The causes of a positive Babinski sign are more varied, and are most often seen as a result of a cone bundle injury, but also as a result of drug intoxication, among other things. In addition, Babinski’s sign can also be seen in infants before the development of the pyramidal tract is complete, and in adults in deep sleep or under anesthesia. To examine Babinski’s sign, the patient is placed in the supine position, with the hip and knee joints straightened. The examiner holds the upper part of the ankle in his left hand to immobilize the calf, while the right hand holds a metal rod with a blunt tip, which is quickly and gently slid from the lateral plantar surface of the foot backward and forward to the root of the little toe, and then turned to the side of the bunion. A positive patient presents with a dorsiflexed bunion and the rest of the toes spread out in a fan-like pattern. This condition is most commonly seen clinically in cone-bundle injuries, but also in deep sleep, deep anesthesia, alcoholism, drug intoxication, stroke, and spinal cord lesions. Positive Babinski’s sign can also be seen in people with excessive foot stabbing pain, pain hypersensitivity, and bradykinesia. Babinski’s sign can also be seen in infants before the cone bundle is fully developed. It is recommended that patients with positive Babinski’s sign should consult a doctor in time and actively cooperate with the doctor to find out the cause of the disease and then treat it, so as to avoid delaying the disease.
