Collaborative peer to peer learning for shoulder ultrasound and anatomy

Peer-assisted learning (PAL) has demonstrated improvement in students' theoretical and practical knowledge and confidence. This pilot study evaluated the efficacy of PAL as a teaching tool and learning method for sonography and physical therapy (PT) students in the study of shoulder ultrasound. This research was also designed to nurture a cross-collaborative spirit between students of two allied health academic programs. This descriptive study employed a pre-test/post-test research design, measuring the efficacy of PAL between sonography and PT students. Student groups taught and learned shoulder ultrasound and anatomy. Multiple-choice tests and questionnaires evaluated knowledge of shoulder anatomy and physiology, ultrasound knowledge, use of ultrasound machine, student confidence, acquired sonographic skills, training quality and satisfaction. Wilcoxon signed-rank test showed significant improvement in students’ knowledge (p = 0.02 for PT students, p = 0.04 for sonography students). Students also reported increased confidence and improved shoulder anatomy knowledge and scanning skills. Our research showed PAL to be an effective method for sonography and PT students to learn shoulder ultrasound and collaboration. PAL can augment shoulder ultrasound curriculum, introduce musculoskeletal (MSK) sonography to other professions, and foster collaborative practice.
