Reflex hammer

Reflex Hammer

A Reflex Hammer (pronounced: /ˈriː.flɛks ˈhæ.mər/) is a medical instrument used by practitioners to test deep tendon reflexes. Testing for reflexes is an important part of the neurological physical examination in order to detect abnormalities in the central or peripheral nervous system.

Etymology

The term "Reflex Hammer" is derived from the Latin word "reflexus", meaning "reflection", and the Old English word "hamor", meaning "tool for striking". The name is indicative of the tool's use in eliciting reflex responses from the body.

Types of Reflex Hammers

There are several types of reflex hammers, each named after the neurologist who invented them. These include:

Taylor's Hammer: A triangular rubber head used for eliciting responses.
Babinski Hammer: A multi-positional head used for eliciting plantar and abdominal responses.
Tromner Hammer: A dual mallet-type reflex hammer designed for eliciting myotatic and plantar responses with less effort and greater patient comfort.

Usage

The reflex hammer is used to test patient reflexes. The practitioner taps the hammer on the location of a tendon, which sends a signal to the spinal cord and back, causing the muscle to contract. This can help identify any potential issues with the patient's nervous system.
