Stretch injury to the brachial plexus may occur following traumatic flexion-extension of the cervical spine often seen in motor vehicle accidents or falls. Radiologic and conventional nerve conduction studies are negative in many cases. The present study was undertaken in an attempt to simplify, standardize, and quantify the positive and negative sensory abnormalities that are most often seen during the clinical examination. ⋯ Quantification of sensory findings may greatly facilitate and substantiate the diagnosis of this type of injury. The data are consistent with the hypothesis that brachial plexus traction injury causes dysfunction of small sensory fiber systems and results in a form of neuropathic pain.
