The ambiguity associated with the brachioradialis reflex is reflected in the descriptions given of the response. Some authors include only flexion of the forearm (e.g., Bann, p. 107 [Table 3.1]; Bick, p. 184); whereas some others note supination as well (e.g., DeJ, p. 432; chus, p. 240). Most discrepant in this regard is the description given by Massey, Pleet, and Scherokman—namely, dorsiflexion of the wrist (p. 59 [Table 4–2]). I can only assume that they are tapping the dorsal aspect of the distal radius, probably with the forearm fully pronated and the wrist partially ventroflexed. If so, they are stretching the tendons of radial extensors of the wrist (e.g., extensor carpi radialis longus, extensor carpi radialis brevis), thereby eliciting a variant of the “wrist extension reflex” (DeJ, p. 434–435). Such an example shows how even additional reflexes may become confused with the brachioradialis reflex if authors do not specify the details of elicitation adequately.

Muscle stretch reflexes are examined at the jaw (masseter) and in the upper and lower extremities, usually including at minimum the biceps brachii, triceps, brachioradialis, quadriceps, and gastrocnemius-soleus reflexes (Achilles’ or ankle reflex). The technique for obtaining the distal brachioradialis reflex and gastrocnemius–soleus reflex is shown in Figure 6.6, in the upper and lower frames, respectively. The presence or absence of primitive or atavistic reflexes, such as snout, palmomental, grasp, Babinski, and Chaddock reflexes, is documented. The technique for testing for the palmomental and Babinski reflexes is shown in Figure 6.7, in the left and right frames, respectively.

An absent reflex may be accompanied by hyperactive reflexes below the spinal level if there is spinal cord involvement (e.g. an “inverted brachioradialis reflex”) with reflex loss but with brisk finger jerks instead.

The neurological examination was performed in sitting. Biceps, triceps, and brachioradialis reflex testing were found to be normal bilaterally. Significant findings included C6 myotomal weakness and decreased sensation over the thenar eminence and volar aspect of the first and second digits (Table 1).
