Differences in learning retention and experience of augmented reality notes compared to traditional paper notes in a chiropractic technique course: A randomized trial

To investigate if a written guide or augmented reality (AR) guide improves free recall of diversified chiropractic adjusting technique and to capture participants' impressions of the study in a poststudy questionnaire.

Thirty-eight chiropractic students were evaluated for diversified listing (a nomenclature denoting vertebral malposition and correction) recall, pre-AR and post-AR, or written guide review. The vertebral segments used were C7 and T6. Two randomized groups reviewed an original course written guide (n = 18) or a new AR guide (n = 20). A Wilcoxon-Mann-Whitney (C7) and t test (T6) compared group differences in reevaluation scores. A poststudy questionnaire was given to capture participants' impressions of the study.

Both groups showed no significant differences in free recall scores after reviewing the guides for C7 or T6. The poststudy questionnaire suggested a number of strategies could be used to improve current teaching material such as more detail in the written guides and organizing content into smaller blocks.

Use of an AR or written guide does not seem to change participants' free recall ability when used to review diversified technique listings. The poststudy questionnaire was useful to identify strategies to improve currently used teaching material.
