During ROM in an unconscious patient with increased ICP, decerebrate posturing occurs. Which action is most appropriate?

• A. Use restraints to protect the patient from injury
• B. Administer CNS depressants to lightly sedate the patient
• C. Continue the exercises because they are necessary to maintain musculoskeletal function
• D. Perform the exercises less frequently because posturing can increase ICP

Answer: (D)

When ICP is elevated, the brain becomes very sensitive to stimuli, and decerebrate posturing indicates brainstem injury with a high risk of further ICP rise from even minor stimulation. Range-of-motion movements can provoke increases in ICP, especially if the patient is uncomfortable or resists the movements, which can trigger a sympathetic and hemodynamic response that raises intracranial pressure. The safest approach is to limit ROM frequency to minimize these ICP spikes while still providing some movement to prevent contractures. If ROM is performed, keep movements very gentle and brief, ensuring the head is neutral and elevated as appropriate, and monitor closely for any signs of ICP rise. This approach balances the need to maintain mobility with the imperative to avoid provoking dangerous increases in ICP.
