Using a Reflex Hammer Properly
- 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.

Which part of the reflex hammer will you use?
How will you determine whether or not the calcaneal reflex exists using the reflex hammer’s head? The side with a lot of rubber.
What is the pointed side of the reflex hammer used for?
Soft rubber hammer with tomahawk form for percussing most tendons and rounded point for reaching biceps tendon or percussing muscles directly on the biceps tendon with this hammer. An open loop at one end of the handle was used originally; the pointed end was introduced around 1920 for the purpose of inducing cutaneous responses.
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 is a normal knee reflex?
The natural knee-jerk response does not require any input from or output to the brain. When the knee is tapped below the knee cap, the usual knee-jerk reaction, also known as the “patellar jerk,” is evoked (patella). Electromagnetic impulses are sent back to the spinal cord when sensors in this location detect straining of a tendon in this area.
What is a normal DTR?
No information is received or sent to the brain during a typical knee-jerk response in humans. When the knee is tapped below the knee cap, the usual knee-jerk reaction, also known as “patellar jerk,” is evoked (patella). Electrical impulses are sent back to the spinal cord when sensors detect stretching of the tendon in this location.
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.

Which reflex should be tested by striking the reflex hammer against the health care provider’s thumb instead of striking the client directly?
This is known as the Deltoid Reflex (Figure 14) Technique: Palpate the deltoid tendon at the junction of the upper and middle thirds on the lateral face of the humerus, which is located at the junction of the upper and middle thirds. Strike the finger with a reflex hammer to cause it to swell.
What happens if the patellar reflex is elicited?
The acute tap on the tendon causes the quadriceps, a group of muscles located at the front of the upper thigh, to gradually swell and stretch. These muscles contract as a result of the response, and the contraction has the effect of straightening the leg in a kicking motion.
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.
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.
