A football player sustains a helmet-to-helmet collision; if the resulting rapid head acceleration induces diffuse axonal injury via shear strain, which recovery protocol will be most effective?

💡 Explanation

Axonal injury from shear strain causes metabolic crisis and impaired neuronal function; therefore, strict cognitive and physical rest is crucial for recovery, because it reduces energy demand and promotes healing, rather than exacerbating the injury with activity.
