1. Have the subject remove a shoe and sock and position the knee on the seat of a chair.
2. tap the Achilles tendon sharply with a reflex hammer.
3. observe the foot for any motion- the expected response should last between 100 and 300 msec so it may be difficult to visualize.

What is the effector of the Achilles reflex?
gastrocnemius muscle
What nerve is tested in a biceps reflex test?
musculocutaneous nervethe musculocutaneous nerve
What is the receptor of the Achilles reflex?
The receptor for the Achilles reflex is the muscle spindle located within the calf muscle (gastrocnemius and soleus muscles). When the Achilles tendon is tapped, it stretches these muscles causing a reflex contraction that is mediated by the spinal nerves.
Achilles tendon when hit with a refelx hammer?
Hitting the Achilles tendon with a reflex hammer can elicit a normal reflex called the Achilles reflex or ankle jerk. This test assesses the integrity of the S1 and S2 nerve roots. A brisk contraction of the calf muscles and a slight plantar flexion of the foot is the normal response.
Do you capitalize Achilles reflex?
Yes, "Achilles reflex" should be capitalized as it refers to a proper noun, which is the name of a specific medical reflex test.
What level of the spinal cord does the Achilles reflex test?
The Achilles reflex is also known as the ankle-jerk reflex. it is controlled by the S1 segment of the spinal chord and occurs when the Achilles tendon is struck with a rubber hammer.
What movement would you expect to occur during the Achilles reflex?
During the Achilles reflex test, you would expect to see plantar flexion of the foot, where the foot points downwards, in response to tapping the Achilles tendon. This reflex is a protective mechanism that helps maintain posture and balance in the lower extremities.
Why is the Achilles reflex important in walking?
science
What happens during ankle reflex?
An ankle reflex is when the Achilles tendon is tapped while the foot is stretched out. A positive outcome is when the foot jerks outward. The test is done to determine if S1 and S2[3] nerve roots are in place.
How would you assess the calcaneal reflex?
To assess the calcaneal reflex (also known as the Achilles reflex), strike the Achilles tendon with a reflex hammer while the patient is lying prone with their foot relaxed. A normal response is plantar flexion of the foot. Absent or diminished reflex may indicate nerve damage or disorders such as peripheral neuropathy.
How do you test vagus nerve?
The function of the vagus nerve can be tested through various methods such as measuring heart rate variability, performing a gag reflex test, or assessing the cough reflex. Additionally, specialized medical tests like nerve conduction studies or imaging techniques may be used to evaluate the integrity and functioning of the vagus nerve.
Achilles reflex protects which 2 muscles?
The Achilles reflex protects the calf muscles, specifically the gastrocnemius and soleus muscles. This reflex is important for maintaining balance and coordination while walking or running.
