It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it. A positive result would be the jerking of the foot towards its plantar surface. Being a deep tendon reflex, it is monosynaptic. It is also a stretch reflex. These are monosynaptic spinal segmental reflexes.
The gastrocnemius muscle may also become inflamed due to overuse. Anti-inflammatory medications and physical therapy (heat, massage, and stretching) may be useful. Anatomical abnormalities involving the medial head of gastrocnemius muscle result in popliteal artery entrapment syndrome.
Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).

This stretch can help to increase flexibility in your calf muscles, which will in turn help to combat the discomfort in the Achilles tendon. How to Do It: Start in a long seated position.
A sudden stretch, such as tapping the Achilles' tendon, causes a reflex contraction in the muscle as the spindles sense the stretch and send an action potential to the motor neurons which then cause the muscle to contract; this particular reflex causes a contraction in the soleus-gastrocnemius group of muscles.
Clonus at the ankle is tested by rapidly flexing the foot into dorsiflexion (upward), inducing a stretch to the gastrocnemius muscle. [1] Subsequent beating of the foot will result, however only a sustained clonus (5 beats or more) is considered abnormal.
