Deconstructing the Joint Examination: A Novel Approach to Teaching Introductory Musculoskeletal Physical Examination Skills for Medical Students.

INTRODUCTION

Musculoskeletal (MSK) disorders are very common, but suboptimal teaching of MSK medicine occurs and expert clinicians agree that MSK physical examination (PE) skills can be confusing and complicated for medical students. An innovative approach in introductory teaching of MSK PE skills was developed using constructivist theory for second-year medical students.

METHODS

We implemented the MSK PE curriculum innovation in the second year of a four-year MD program, utilizing a standard framework with spaced practice and clinician coaching. We evaluated this curriculum by comparing the innovation group ( = 123) to a historical control group ( = 134) using an anonymous survey and OSCE station scores. Data analysis included repeated measures analysis of variance comparing students' self-confidence in MSK PE to students' self-confidence in other systems-based PEs, as well as independent -test comparisons of self-confidence scores and MSK-specific OSCE station scores between the historical and innovation groups.

RESULTS

The mean self-assessed confidence of the historical group was significantly lower for the MSK PE than all other PEs ( < 0.001), except for the neurological PE. Significant improvement in MSK PE self-confidence was noted with the innovation group ((259) = -4.05, < 0.001). OSCE scores significantly improved in MSK-specific stations, with medium to large effect size across the different stations.

DISCUSSION

We successfully used a framework of deconstruction, repetition, and spaced practice to develop fundamental MSK PE skills in preclerkship medical students. This curriculum structure provides an effective example for teaching introductory MSK PE skills to early medical learners.
