When is padding underneath the torso generally unnecessary for immobilizing a child?

Padding underneath the torso is generally unnecessary for immobilizing a child who is older than 8 to 10 years of age due to the increased development of the chest and torso in this age group. As children grow, their bodies become more robust and proportionally mature. The anatomy of older children allows for more effective stabilization without additional padding, as they often fit more securely into standard immobilization devices designed for adults or larger children.

In younger children, particularly those under 5 years of age, the torso may be proportionally larger or less rigid, making padding necessary to ensure proper alignment and to prevent movement during transport. Children between 5 to 7 years of age are still developing, and cushioning might still play a key role in securing them appropriately. For adolescents, the need for padding likewise diminishes due to their physical maturation and size. Therefore, the need for padding primarily relates to the child's developmental stage and anatomical proportions, making it generally unnecessary for the older age group.
