What is the JFK CRS-R and what does it measure?

• A. The JFK Coma Recovery Scale-Revised; measures arousal and functional neurobehavioral recovery in severely brain-injured patients
• B. A motor strength scale used for gait assessment
• C. A visual acuity test adapted for brain injury
• D. A global neurological recovery index focusing on reflexes

Answer: (A)

The JFK CRS-R is a structured, clinician-scored tool used to assess the level of consciousness in people with severe brain injury. It specifically measures arousal and functional neurobehavioral recovery, capturing meaningful signs of consciousness across multiple domains rather than just reflexes or basic senses. The scale covers areas such as auditory, visual, motor, oromotor/verbal, and communication abilities, plus a general arousal measure, allowing clinicians to detect subtle responses that indicate emerging or fluctuating consciousness and to track changes over time. This helps distinguish levels like coma, vegetative state, and minimally conscious state and guides prognosis and treatment decisions. The other options don’t fit because this tool is not a motor-strength scale, nor a visual acuity test, nor a reflex-focused global neurological index.
