Why do we test the Achilles reflex?
The Achilles reflex checks if the S1 and S2 nerve roots are intact and could be indicative of sciatic nerve pathology. It is classically delayed in hypothyroidism. This reflex is usually absent in disk herniations at the L5—S1 level. A reduction in the ankle jerk reflex may also be indicative of peripheral neuropathy.
What does tendon reflex indicate?
Tendon reflexes are important because they provide an objective sign indicating abnormality and some indication as to the level of the abnormality. Reflexes can be graded as absent, obtainable with reinforcement (see below), reduced, normal, increased and increased with clonus.
What does the Achilles tendon reflex protect and how?
Trunk and leg muscles respond to support the body in its sudden change of position, and the head and eyes turn to look at the cause of the injury. All this happens while the person is becoming aware of the burning sensation. A reflex that protects the body from injury, as this one does, is called a nociceptive reflex.
What movement is observed in Achilles reflex?
stretch reflex
The Achilles reflex is a monosynaptic stretch reflex similar to the patellar reflex. In the Achilles reflex, the hammer taps the Achilles tendon while the foot is dorsiflexed, and the foot, in response, should jerk toward the plantar surface. The Achilles reflex originates in the S1 and S2 nerve roots.
What causes absent Achilles reflex?
[2] Physiologic derangements caused by diabetes mellitus, hypothyroidism, uremia, vitamin or electrolyte deficiencies, and toxins such as lead or arsenic can commonly present with hyporeflexia. Diminished or absent Achilles tendon reflex is commonly seen in patients with hypothyroidism or diabetes mellitus.
What is a reflex test?
Reflex testing is an important tool in providing timely, cost-effective and quality care to patients. A reflex test is a laboratory test performed (and charged for) subsequent to an initially ordered and resulted test.
Why is the Achilles reflex important in walking?
The Achilles tendon (AT) has the capacity to store and release elastic energy during walking, contributing to metabolic energy savings.

What nerve is tested for Achilles reflex?
The ankle jerk reflex, also known as the Achilles reflex, occurs when the Achilles tendon is tapped while the foot is dorsiflexed. It is a type of stretch reflex that tests the function of the gastrocnemius muscle and the nerve that supplies it.
Is the Achilles reflex cord-mediated reflexes?
Achilles reflex patellar reflex (crossed extensor reflex is also cord-mediated) abdominal plantar (also the corneal and gag reflexes) Yes, in a singly pithed frog in which the cord is intact. It is a cord-mediated reflex (initiated and executed at the spinal cord level).
