The main purpose of in-line stabilization is to stabilize and restrict motion of the head, neck, and back during a rescue or emergency situation. This technique is crucial, especially when there is a suspicion of spinal injury, as any movement of these areas could potentially exacerbate the injury or lead to further damage. By providing in-line stabilization, a rescuer ensures that the victim's spine remains aligned and minimizes any risk associated with movement.

In situations where spinal injuries may be present, it's essential to limit the victim's mobility to prevent complications. Other options do not align with the primary focus of in-line stabilization; for instance, allowing full movement of the head and neck could lead to severe consequences if an injury exists, and eliminating the need for spinal support would also contradict the protocol for managing potential spinal injuries. Additionally, while comfort is important in a rescue scenario, it is secondary to ensuring the victim's safety and preventing further harm. The priority remains on maintaining proper alignment and minimizing motion of these critical areas.
