A hyperactive pectoralis muscle reflex elicited by tapping the pectoralis tendon in the deltopectoral groove causing adduction and internal rotation of the shoulder is a sign of cord compression in the upper cervical spine (C2-3, C3-4 spinal levels).13 The “dynamic” Hoffmann's sign (when a typical Hoffmann's sign is elicited after having the patient flex and extend the neck multiple times) may be an indicator of early CSM.14  Hyperreflexia may be absent in CSM patients who have concurrent diabetes, causing a peripheral neuropathy (Table 1).
