Objective:

To evaluate the educational effectiveness of a novel, web-based neuroanatomical localization application.

Methods:

A prototype version of a neuroanatomical localization application was developed, limited to lesions involving Cranial Nerve (CN) VII. Second year medical students at the University of Ottawa were recruited to participate in the study. Participants were exposed to a didactic teaching session on CN VII anatomy. They were subsequently randomized to two groups - one group was granted access to the localization application (the “intervention group”), while the other group was given a booklet of standard textbook resources (the “control group”). Participants then completed a case-based multiple choice test on localization of neurologic lesions associated with CN VII, followed by a questionnaire regarding the experience.

Results:

Thirty-nine students volunteered to participate. Twenty were randomized to the intervention group and 19 to the control group. There was a mean test score difference of 1.3 (CI.95 = 0.2, 2.3) that was significantly higher in the intervention group when compared to the control group. Significance was determined by aWilcoxon rank test (p = 0.028). Questionnaire results were similar for both groups, showing an overall favourable evaluation of the localization application.

Conclusions:

The results support our hypotheses that students using the application would perform better on the multiple choice question (MCQ) test and there would be an overall preference for its use. The demonstrated educational benefit of the application, in addition to the demand for such a resource expressed by the participants, warrant further investigation into the development of a neurological localization application.
