Research has shown the King-Devick Test to be additive to other sideline concussion assessments such as balance and cognition ( Neurology Clinical Practice, Vision Testing is Additive to the Sideline Assessment of Sports-Related Concussion, 2014).King-Devick Test is for assessment purposes only and any suspicion or indication of concussion should be evaluated by a licensed professional.Some off-label uses of devices described in the peer-reviewed scientific research have not been cleared by FDA. K-D Balance is FDA 510(k) cleared as a balance assessment tool. *King-Devick Test has FDA pre-amendment certification for the assessment of saccadic eye movements.

Any worsening of King-Devick Test from baseline indicated a five-times greater likelihood of concussion ( Concussion, The King-Devick test of rapid number naming for concussion detection: meta-analysis and systematic review of the literature, 2016).*

High Sensitivity & SpecificityĪ recent meta-analysis found King-Devick Test to be both sensitive (86%) and specific (90%) for the detection of concussion. Peer-reviewed research has shown that adding a vision-based performance measure to cognitive and balance testing enhances the detection capabilities of current sideline concussion assessment ( Journal of Neuro-Ophthalmology, Adding Vision to Concussion Testing: A Prospective Study of Sideline Testing in Youth and Collegiate Athletes 2015).* The K-D Test is a recommended component of the Mayo Clinic Sideline Concussion Protocol.
