Patient-Reported Outcomes and Provocative Testing in Peripheral Nerve Injury and Recovery.

Abstract

Background  Peripheral nerve function is often difficult to assess given the highly variable presentation and subjective patient experience of nerve injury. If nerve assessment is incomplete or inaccurate, inappropriate diagnosis and subsequent treatment may result in permanent dysfunction. Objective  As our understanding of nerve repair and generation evolves, so have tools for evaluating peripheral nerve function, recovery, and nerve-related impact on the quality of life. Provocative testing is often used in the clinic to identify peripheral nerve dysfunction. Patient-reported outcome forms provide insights regarding the effect of nerve dysfunction on daily activities and quality of life. Methods  We performed a review of the literature using a comprehensive combination of keywords and search algorithms to determine the clinical utility of different provocative tests and patient-reported outcomes measures in a variety of contexts, both pre- and postoperatively. Results  This review may serve as a valuable resource for surgeons determining the appropriate provocative testing tools and patient-reported outcomes forms to monitor nerve function both pre- and postoperatively. Conclusion  As treatments for peripheral nerve injury and dysfunction continue to improve, identifying the most appropriate measures of success may ultimately lead to improved patient outcomes.
