Abstract: A method for measuring and recording reflex response includes the steps of attaching an electrode to a first part of a test subject, connecting the electrode to an electrocardiograph, striking a body part of the test subject to elicit a reflex response, or stimulating a reflex by electrical current directed to the tendon, the current being similar to one generated by an electromyograph or a cardiac pacemaker, and measuring and recording the reflex response on the electrocardiograph. The method provides a simple, reliable procedure for producing accurate recordings of a patients reflex responses.
