INTRODUCTION: The aim of the study was to compare the utility of instrument-based assessment of peripheral nerve function with the neurologic examination in ulnar neuropathy at the elbow (UNE).
METHODS: We prospectively recruited consecutive patients with suspected UNE, performed a neurologic examination, and performed instrument-based measurements (muscle cross-sectional area by ultrasonography, muscle strength by dynamometry, and sensation using monofilaments).
RESULTS: We found good correlations between clinical estimates and corresponding instrument-based measurements, with similar ability to diagnose UNE and predict UNE pathophysiology.
DISCUSSION: Although instrument-based methods provide quantitative evaluation of peripheral nerve function, we did not find them to be more sensitive or specific in the diagnosis of UNE than the standard neurologic examination. Likewise, instrument-based methods were not better able to differentiate between groups of UNE patients with different pathophysiologies. Muscle Nerve 57: 951-957, 2018.
