Computer-Aided Localisation of Peripheral Nerve Lesions

Abstract

The clinical localisation of peripheral nerve lesions can sometimes be difficult, particularly following injury to the brachial plexus when multiple lesions are often present. In this situation, computers may be of assistance in interpreting the complicated patterns of clinical findings. This paper describes the evaluation of a computer program that uses a simulation model of the consequences of nerve injury, based on a representation of the relevant anatomy. A retrospective study of 26 patients with upper limb nerve lesions was carried out. The computer program compared favourably with three clinicians in interpreting the findings correctly. It is suggested that this approach may be transferable to other applications.
