Synkinetic wrist extension in distinguishing cortical hand from radial nerve palsy

Pract Neurol. 2018 Dec;18(6):520-521. doi: 10.1136/practneurol-2018-001971. Epub 2018 Jun 12.

Abstract

We describe a patient with pseudoradial nerve palsy caused by acute ischaemic stroke ('cortical hand') to emphasise how preserved synkinetic wrist extension following fist closure can distinguish this from peripheral causes of wrist drop.

Keywords: differential diagnosis; padial nerve palsy; pseudoradial nerve palsy; stroke.
