When present, these associative conditions may contribute to a clinical diagnosis of Cerebral Palsy. American College of Obstetricians and Gynecologists, American Academy of Pediatrics. Arch Dis Child. Underdeveloped or lacking postural and protective reflexes are warning signs for abnormal development, including Cerebral Palsy. Signs of Cerebral Palsy are different from symptoms of Cerebral Palsy. The primitive reflexes and the postural reactions comprise one of the earliest, simplest, and most frequently used tools among child neurologists to assess the central nervous system integrity of infants and young children.

The chair should be therefore appropriately adapted for ability, ensuring sufficient control of the childs posture yet at the same time it should encourage the child to develop as much independent sitting ability as possible facilitating at the same time daily activities such as eating, playing and learning[3]. During the first 1 -2 months of life, a number of reflexes develop in sequence, including the Tonic Reflexes: Tonic Labyrinthine, Symmetrical and Asymmetrical Tonic Neck, Head Righting and Trunk Extension Reflexes, and pelvic-trunk movement patterns.

Abnormal primitive reflexes may not function properly in children with Cerebral Palsy, or they may not disappear at specific points in development as they do with children with no impairment. Cerebral Palsy is caused by a brain injury or brain abnormality that interferes with the brain cells responsible for controlling muscle tone, strength, and coordination. Use cabinet locks, doorknob covers, and gates where [6] Primitive reflexes have been an ignored parameter in treatment of patients with cerebral palsy.

MyChild does not provide legal services. The earlier a diagnosis is made, the sooner a child can be enrolled in early intervention programs and treatment protocols. Very early treatment, if possible before the age of 6 months, gives a child the best chance of improvement for the following reasons: (1) In the infant, motorbehaviour is largely We link primary sources including studies, scientific references, and statistics within each article and also list them in the resources section at the bottom of our articles.
