Tendon reflex (or T-reflex) may refer to:
- A stretch reflex, when the stretch is created by a blow upon a muscle tendon. This is the usual definition of the term.  A common example is the standard knee-jerk response when visiting the doctor.  Deep tendon reflex also usually refers to this sense. A deep tendon reflex is often associated with muscle stretching.  Tendon reflex tests are used to determine the integrity of the spinal cord and peripheral nervous system, and they can be used to detect the presence of a neuromuscular disease. 
- The Golgi tendon reflex, motivated by that the sensory receptors for this reflex are anatomically located in the tendon, while the sensory receptors for the stretch reflex are actually inside the proper muscle.
Functions of Tendon Reflex
The tendon reflex is a response to extensive tension on a tendon. It helps avoid strong muscle contractions which could tear the tendon from either the muscle or bone. In sports, quick movements can damage the tendon before the reflex can occur. The tendon reflex also helps spread the workload more evenly over the entire muscle by preventing “muscle fibers connected with overstimulated tendon organs so that their contraction is more comparable to the contraction of the rest of the muscle.”
