K-D Test products measure eye movement speed and accuracy during rapid number naming in which a series of single-digit numbers is read aloud.
Performance on the K-D Test requires vision and eye movements involving the integrated function of the brainstem, cerebellum and cerebral cortex (Lancet, The Neuro-ophthalmology of Head Trauma, 2014). Cognitive processing is also required including:
MEMORY • ATTENTION • LANGUAGE FUNCTION
Pathology in any of these functional pathways may result in errors and poor K-D Test performance (Concussion, The King-Devick test of rapid number naming for concussion detection: meta-analysis and systematic review of the literature, 2016).
Vision alone accounts for more than 50% of the brain’s pathways, making vision and eye movements particularly vulnerable in brain injury (Lancet, The Neuro-ophthalmology of Head Trauma, 2014).
Neurological Pathways Involved in K-D Test Performance
Highlighted areas shown here include those responsible for planning, initiation and execution of the coordinated functions of vision, eye movement, attention, language and concentration required for successful performance on the K-D Test (Lancet, The Neuro-ophthalmology of Head Trauma, 2014).
