Attention is immediately moved to the neck where bone and muscle symmetry is assessed by close palpation, and the local cutaneous coli and cervicofacial responses are seen and felt. A solid blunt instrument, such as 15–25 cm artery forceps or needle holders, is best for performing this and other cutaneous testing. On occasion, with a very frightened patient, the tip of a rigid index finger may have to suffice as being better tolerated. A firm thrust needs to be applied over sites at the level of and 10–15 cm dorsal to the articular processes of cervical vertebrae to consistently induce these cervical responses. The two‐pinch technique is used to test cervical dermatomes and to test limb autonomous zones for areas of hypalgesia if a reflex suppression or a final motor neuron lesion are suspected. Regional muscle atrophy, bony asymmetry, and areas of sweating are to be noted.
