Phase 1 was designed to help patients prepare for progressive resistance training and reduce any chance of secondary injuries.

Injured axons in the brain's white matter may separate from their cell bodies as a result of secondary injury, potentially killing those neurons.

On the other hand, secondary injury occurs gradually and may involve an array of cellular processes.

This is often a result of secondary injury, which can damage even neurons that were unharmed in the primary injury.

Similar mechanisms are involved in secondary injury after ischemia, trauma, and injuries resulting when a person does not get enough oxygen.

However, since secondary injury occurs over time, it can be prevented in part by taking measures to prevent complications such as hypoxia.

Furthermore, secondary injury presents opportunities for researchers to find drug therapies to limit or prevent the damage.

Most casualties are caused by secondary injuries.

Some explosives, such as nail bombs, are deliberately designed to increase the likelihood of secondary injuries.
