Cerebral palsy is a non-progressive brain injury caused by various reasons from the mother’s gestation to infancy, mainly manifested as active movement disorders and postural abnormalities (e.g., hand clenching, inward thumb, pointed foot, crossed, poor head and neck control, abnormalities in sitting, standing, walking, etc.), often accompanied by mental retardation, visual abnormalities, hearing loss, speech impairment, epilepsy and cognitive behavior abnormalities. The key to the treatment of cerebral palsy is “the key to the development of the brain”. The key to the treatment of cerebral palsy is “early detection, early diagnosis and early treatment”, in which ultra early treatment is within 3 months and early treatment is within 6 months. Due to the lack of knowledge about cerebral palsy, many children miss the best treatment period, resulting in lifelong disability and disastrous consequences for the child and the family’s well-being. Symptoms of pediatric cerebral palsy tend to appear in infancy, and there are usually obvious abnormalities at around 6 months of age, with some signs appearing in severe cases. So what are the specific signs of cerebral palsy in the early stages? The following are the manifestations of cerebral palsy in different periods. 1.Neonatal period: short gaze and chasing time, slow response to sound and light stimulation, weak sucking or choking, slow weight gain, no crying or weak crying, or abnormal crying, sleep difficulties; easy to be frightened, excessive flabbiness or hardness of the whole body, obvious reduction of movement, dull sense of touch, especially the eyes, perioral area, palms, soles, etc., late response to touch; no blinking, mouth opening, retraction of hands and feet, etc. 2.1~3 months: not paying attention to people, not gazing, not chasing, not smiling, head cannot be erected straight or tilted back, difficulty in raising head in prone position, both upper limbs cannot support trunk, shoulders on bed, hips elevated. The thumb is inward, the hand is clenched in a fist or the forearm is rotated inward and backward, the limbs are strong, and the resistance is obvious when moving passively. Bilateral limb posture and activities are asymmetrical. 3.4~5 months: Dull expression, no recognition, slow response when teasing. The baby does not reach out to grasp objects or has abnormal grasping posture, does not roll over, raises the head less than 90 in prone position, and cannot lift the chest. Sitting position is full forward leaning or backward jerking. Both lower limbs are crossed and toes are on the ground. 4.6 months: slow reaction, short attention span, not interested in toys, late response to sound, does not recognize mother, does not play in the mirror, does not sit at 6 months, stiff or floppy limbs, upper limb posterior extension (commonly known as airplane hand), toe pointing when supporting standing, foot inversion, foot valgus, crossed gait. In addition, children with cerebral palsy have abnormal muscle tone and posture, mainly manifesting as over-exertion of energy during passive activities, reduced range of motion of joints, and muscle stiffness, such as difficulty in thigh abduction, knee flexion that is not easily straightened, straightening and inwardness of the legs when held upright, crossed legs in a scissors shape, flexion of the elbow and wrist joints of the upper limbs, and frequent clenching of the hands with the thumbs inward. Older children have many behavioral abilities, so any abnormalities can be easily detected and diagnosed. Parents should not delay the detection of cerebral palsy in early childhood, but should make sure that treatment and training are carried out as soon as possible. The earlier the treatment and training, the better the recovery. In addition, the diagnosis of cerebral palsy is very scientific and rigorous, so you should not diagnose your child with cerebral palsy simply by matching the numbers and finding a little abnormality, which will cause unnecessary worries. If you find any abnormalities in your child, it is best to go to a regular hospital for examination and clear diagnosis.
