Abstract

Background and Purpose

Chronic pain is a common problem and imaging is becoming increasingly utilized in the characterization of peripheral neuropathy although this topic is not emphasized during medical training. We hypothesized that an electronic module and nerve atlas would be effective in improving comprehension among trainees.

Materials and Methods

In this IRB approved study, a training module was created that included a side-by-side comparison of normal upper extremity nerves on MRI and US, with embedded questions and cases, followed by a brief hands-on US scanning session. Thirty volunteers with variable training were enrolled in one institution while fourteen volunteers were enrolled in another. Pre- and post-test scores were collected and compared.

Results

There was a response rate of 100% at both institutions. At the first institution, subjects were divided into two groups: group 1 (16 medical students) and group 2 (14 residents/fellows). There was a baseline deficit of knowledge among both groups, with a mean pre-test score of 37.5% and 47.5% for group 1 and group 2 respectively (p=0.017). After module completion, both groups improved with a mean post-test score of 67.2% for group 1 and 76.1% for group 2. At the second institution, there was similar improvement even if the scanning session was not done.

Conclusions

Use of an electronic module helps trainees to become more familiar with peripheral nerve imaging, regardless of level of training. Use of the module, even in the absence of hands on US scanning, results in an improved understanding of this topic.
