Definition & Meaning of "reflex hammer"

What is a "reflex hammer"?

A reflex hammer is a medical tool used by healthcare professionals to test reflexes in patients during physical examinations. It typically has a handle with a rubber or plastic head designed to strike specific areas of the body, such as the knee, elbow, or ankle. When tapped with the reflex hammer, these areas can trigger involuntary muscle reflexes, which help doctors evaluate the condition of the nervous system. Reflex hammers are essential for diagnosing conditions affecting nerve function and overall neurological health in patients.
