Cervical Radicular Pain and Radiculopathy
From WikiMSK
It is not possible to distinguish C6 from C7 radiculopathy with a sensory examination.
Based off data from Rainville et al. [1] The asterix indicates the only area where there is a statistical difference, with impaired in the distal radial aspect of the dorsal forearm more common in C6 than C7 radiculopathy.
