Cervical sensory axonal dysfunction in radiculopathy: A novel concept!

Posted on by Steve Vucic, Web Editor

Cervical radiculopathy is a common issue for neurologists. While motor dysfunction has been traditionally assessing using needle EMG techniques, thereby confirming the diagnosis, frequently only sensory symptoms may be evident. In such cases, the diagnostic time may be protracted.
In an upcoming issue of JNNP (ON-LINE FIRST) Lin and colleagues tackle this issue in a novel manner assessing sensory axonal excitability distal to the site of dysfunction. Interestingly, distal axonal hyperpolarisation was noted even in the presence of normal sensory nerve conduction studies, as traditionally expected. This provides a novel pathophysiological insight into this disorder.
