摘要

Introduction

The purpose of this study was to determine whether exposure to musculoskeletal (MSK) ultrasound (US) enhanced medical students’ knowledge and self-efficacy in understanding basic US principles, MSK anatomy and physical examination, and use of US to evaluate MSK structures.

Materials and Methods

Forty-three second-year medical students were divided into control (n = 22) and experimental (n = 21) groups. All participants completed a pre-session self-efficacy questionnaire and were encouraged to view a recorded 20-min MSK US lecture. All participants then attended a physician-led 35-min MSK US hands-on scanning session covering the shoulder and knee. The control group took a multiple-choice assessment before the session, while the experimental group took the same assessment after the session. All participants completed a post-session self-efficacy questionnaire. After the session, the physician instructors attended a 30-min Zoom focus group.

Results

Participants’ self-efficacy in understanding basic US principles, knee and shoulder anatomy, physical examination, and sonoanatomy significantly improved after the MSK US session (all p < 0.01). Participants who took the content assessment after the MSK US session outperformed participants who took the assessment before the MSK US session (p = 0.02). Qualitative open-ended question responses from students and instructor focus group discussion detailed strengths and shortcomings and proposed actionable improvements for future iterations of the MSK US curriculum.

Conclusion

When implemented at a point in the preclinical curriculum where US experience was previously absent, a single, focused physician-led 35-min US session covering the shoulder and knee is an effective adjunct educational tool for preclinical medical students to reinforce US basics, MSK anatomy and physical examination and improve self-efficacy in MSK US scanning.
