Abstract Details

Assessing the Efficiency of Learning the Neurologic Exam with a Visual Tracking Device

Developing efficient examination skills requires repeated clinical experiences informing or reinforcing didactic learning and prior clinical exposures. Current clinical educational practices use clinical encounters with mentorship to optimize immediate learning and develop focused approaches for subsequent clinical encounters. Visual scanning patterns have demonstrated diagnostic efficiency in radiology and pathology, but have not been explored in neurologic learning or moving patient images.
Using a Sensomotoric Instruments infrared eye tracker, we measure eye movements of pre-clinical medical students, neurology residents, and neurology attendings while they watch brief video clips of standardized neurologic examinations of parkinsonian and normal subjects. We monitor saccade length, sequence, fixation durations, and regions of interest. Learners are randomized to reading a Parkinson disease (PD) book chapter (Merritt's Neurology, 12th edition), multimedia PD chapter (AAN), or a mentored clinical PD encounter. Learners then re-watch the videos to assess interval change.
Results of our first subject (resident) are presented here. The subject watched 2-5 distinct ten-second videos of facial expression, finger taps, toe taps, walking, and pull tests. The resident then read the chapter, and 120 minutes after the initial videos, looked more at subtle physical signs: hand tremors while studying foot taps and subtle hypomimia (brow movement). Subject enrollment is ongoing.
Visual scanpaths hold potential to offer a physiologic basis of learning and clinical assessment, inform practices for neurologic education methods, and provide a novel evaluative tool.
