Which age groups are considerations for spinal motion restriction (SMR)?

The choice that identifies the correct age groups for spinal motion restriction (SMR) reflects current standards where individuals under 16 years old and over 65 years old are particularly considered at higher risk for spinal injuries.

Children under 16 years have unique anatomical and physiological characteristics, including a more pliable spine and differing injury patterns. Their developing bodies may respond differently to trauma and require specific considerations during assessment and management.

Conversely, older adults, particularly those over 65 years, often experience degenerative changes in their spinal structures — such as osteoarthritis or osteoporosis — which increase their susceptibility to spinal injuries. This age group may also have existing comorbidities that can complicate any spinal injuries they might sustain.

In assessing these age groups specifically, it's crucial for responders to apply spinal motion restriction protocols to ensure maximum safety and minimize the risk of exacerbating potential injuries in both younger individuals and the elderly during emergency care.
