Hammer is a very useful medical device used by orthopedic doctors to test the performance of the tendons connecting the lower part of the legs with the thighs. The reaction of the leg when the knee joint gets a slight knock with the instrument will indicate to the doctor if there is any problem with that area. It is just like any other hammer in function but the head is very soft as it is made of rubber which results in painless examination. There are various types of hammers available for the use of doctors.
Reflex hammers are another name by which these hammers are known. The tendons in the legs become weak as years pass by and some people experience the difficulties while walking and living regular life. To help such people and situation, doctors have developed assorted methods of treatment to help them relieve them of their physical constraint. The usage of Knee hammer is one of the parts which can ease out patients with joint pains and arthritis.
How to use a reflex hammer?
The reflex hammer is held by the handle, particularly close to the end opposite the head, with the head resting on the tendon which you propose to test. Ensure that the head is correctly lined up relative to the ligament. The hammer should be detained against the ligament for some time so that the person being examined does not know when to expect the reflex. The hammer is now taken back and bounce on the ligament. It is important to make certain that the hammer has a great velocity at the moment of impact (but don't use too much force to evade hurting the ligament) and that it bounces off the muscle, rather than staying in contact with it. The action should be very quick. It is usually completed in about a second.
