Final answer:

After a denervation injury and the patellar tap reflex test, neither EMG signal nor torque are produced due to the loss of nerve supply to the muscle.

Explanation:

After a person with a complete denervation injury undergoes the patellar tap reflex test, both EMG signal and torque are not produced. This occurs because a denervation injury results in the loss of nerve supply to the muscle, affecting its ability to generate muscle contractions. In the absence of nerve signaling, both muscle activity (as indicated by EMG signal) and force production (torque) are compromised.
