Patellar Reflex Hammer with a BNC connector

The PRH-200 is a Taylor reflex hammer with a piezo sensor attached to

perform reflex measurements and record strike magnitude.

The Threshold of the impact needed to elicit a response can be

determined by measuring the amplitude of the strike.


The Taylor Hammer is the most common type of reflex hammer used by

doctors and nurses.


A piezo sensor is attached to the head of the hammer. When compressed

or stretched, the cable generates a voltage that is somewhat

proportional to the force of acceleration/deceleration;

there must be an impact to generate a response signal—just

swinging the hammer in the air will not produce a response.


The PRH-200 is ideally suited for recording impact stimulation of the

patellar tendon.
