Acute Concussion Evaluation (ACE)
Availability
Please visit this website for more information about the instrument: Acute Concussion Evaluation Form
Classification
Supplemental: Sport-Related Concussion (SRC)
Short Description of Instrument
The Acute Concussion Evaluation Form (ACE) is an evidence-based clinician form that is used to assess individuals with a known or suspected concussion. The ACE can also be used to track symptom recovery over time.
Scoring
The form includes questions about the presence of concussion characteristics, 22 concussion symptoms, and risk factors that might predict prolonged recovery.
Rationale/Justification
Advantages: The ACE was developed to provide a systematic protocol of questions for the clinician to pursue in the evaluation of the injured individual. Built specifically for mild TBI, the ACE includes signs/symptoms as well as injury characteristics, and risk factors for prolonged recovery. The ACE has been used in two relatively large pediatric mild TBI studies.
 
Limitations: Samples include a majority of sports concussion. The ACE has not been administered to non-concussed individuals to establish a base rate of symptoms.
