Shifting the Curve: Mastery Learning to Teach Nerve Conduction Studies in Physical Medicine and Rehabilitation Residency.

Abstract: Nerve conduction studies are a commonly performed procedure and a core competency for physical medicine and rehabilitation residents. Nerve conduction studies are complex to learn and no standardized training protocols exist across physical medicine and rehabilitation programs. The aims of this study are to standardize training and assessment of resident proficiency in nerve conduction studies skills and to evaluate the impact of an educational intervention on skills development. This was a repeated measures design wherein 36 physical medicine and rehabilitation residents underwent a pretest, followed by a mastery learning-based intervention, including deliberate practice. Residents were then expected to meet or exceed a minimum passing score at posttest. Performance improved from a median score of 4.5/66 on the pretest to a median score of 63/66 on the posttest. Thirty-three of 36 residents achieved the minimum passing score on the first attempt; three residents required additional deliberate practice and met the minimum passing score on the second attempt. A curriculum featuring deliberate practice dramatically increased checklist scores of residents performing nerve conduction studies. This mastery learning program shows a reliable and reproducible method to achieve procedural competency within a physical medicine and rehabilitation residency program and can shift the curve to allow residents to immediately start performing nerve conduction studies at the start of their clinical experience.
