Tests for deep tendon reflexes are performed with a percussive hammer. The percussion hammer is used to assess deep tendon reflexes. Deep tendon reflexes are tested using this tool. Tendon reflexes (also known as deep tendon reflexes or tendon jerks) are monosynaptic stretch reflexes that are triggered during a clinical examination by percussion of the tendon of a muscle. Tendon reflexes are also known as deep tendon reflexes or tendon jerks. This results in a quick and transient activation of the dynamic stretch receptors in the body. Each tendon reflex is provided by a distinct section of the spinal cord, as follows: Tendon reflex.https://www.sciencedirect.com/science/neuroscience/tendon-reflex/index.html a brief review of the tendon reflex | ScienceDirect Topics.
- Down-the-hole (DTH) equipment includes a percussion hammer that is attached to the end of a drill string, which is used to drill into the ground. A percussion hammer is primarily employed for the purpose of drilling boreholes in hard rock.

Why do doctors use reflex hammer?
Historically, clinicians have relied on the reflex hammer to examine deep tendon reflexes, which are an important component of the neurological physical examination in order to evaluate the peripheral and central nervous systems.
What is the meaning of percussion hammer?
1A hammer used in a percussion gun to strike the powder or cap, causing it to explode and therefore releasing the charge. 2Medicine. A little hammer that is employed in the field of medicine.
What is a percussion hammer used for in the physical assessment?
The Percussion Hammer is an instrument that is used to assess neurologic reflexes in humans. The instrument’s head is used to evaluate reflexes by striking the tendons of the ankle, knee, wrist, and elbow with a rubber mallet.
How do you use a percussion reflex hammer?
Testing neurologic reflexes with the use of a percussion hammer It is used to assess reflexes by hitting the ankle, knee, wrist and elbow tendons with the head of the instrument.
- Decide on your reaction hammer and grasp it firmly by the handle. Take care to ensure that the muscle group you are testing is neither stretched or contracted (it must be in a neutral posture in order to elicit the proper tendon response). Using a single, swift stroke, strike the tendon and observe the muscular reaction.
What is the thing called that doctors hit your knee with?
A reflex hammer is a medical equipment that is used by practitioners to examine deep tendon reflexes in the hands and wrists.
Why do doctors hammer knees?
If there is an issue with the nerve supply, a response might be diminished or completely missing. Your doctor will tap forcefully on the tendon with a rubber hammer to see how well your reflexes are working. If some reflexes are reduced or missing, it will be possible to determine which nerve is being squeezed. Not all nerve roots are related with a response in the same way.
What does a Plexor do?
Medicine/Medical. An instrument for diagnosing heart disease that is tiny in size and has a soft rubber head or similar features.
What is the medical term for reflex hammer?
An instrument with a tiny, rubber-headed head that is used mostly in medical examination or diagnosis for percussion of nerves in order to elicit reflexes. Also known as a plexor.
What is the meaning of a otoscope?
Otoscopes are instruments that use a beam of light to assist observe and examine the state of one’s ear canal and eardrum. Examining the ear can show the underlying cause of symptoms such as earache, a sense of fullness in the ear, and hearing loss.
How does a tendon hammer work?
The delivery of a hit from a reflex hammer causes the reflex to be activated and become active. In addition to dislocating the tendon and extending the muscle tendon complex, the hammer impact also causes the afferent neurons in the muscle fibers to be stretched. Among those who have contributed to this work are Walker et al (1990).
What are percussion instruments?
A percussionist, in contrast to the majority of the other members of the orchestra, may frequently perform a variety of instruments within a single piece of music. To name a few of the most frequent percussion instruments in an orchestra, there are timpani, xylophone, cymbal and triangle, as well as snare drum and bass drum. Other instruments include tambourine, maracas, gongs and chimes, celesta, and piano.
Is clonus a spasticity?
Clonus is frequently associated with spasticity. It is characterized by long-term muscle tension. Spasticity, such as that observed in clonus, is produced by damaged nerves that travel between the brain, spinal cord, and muscle groups. It is believed that this aberrant activity causes muscular movement disruption by generating involuntary contractions, stiffness, and discomfort in the muscles.
What can be used instead of reflex hammer?
When assessing knee reflexes, press down on the dorsum of the foot while tapping the patellar tendon with your index and middle fingers. With the help of this technique, you may get a decent response when you touch the side of your index finger with the side of your index finger. The use of the index finger eliminates the necessity for a reflex hammer, which may be distressing to the young kid.
Where do you strike for reflexes?
The knee jerk is assessed by hitting the quadriceps tendon directly with the reflex hammer while the lower leg is free to swing freely off the edge of the bench throughout the test.
