To the Editor:—
We have noticed with interest your mention of the kinemometer in the Question and Answers section of The Journal (JAMA178:784 [Nov. 18] 1961). Having been closely associated with the kinemometer for several years, we have performed literally thousands of heel reflex tests and would be interested in knowing if your information is based on firsthand experience with the instrument, or, if not, on what authority you base your answers. We respect your conservative answers in The Journal but suggest that if you would use the test objectively for any period of time you would begin to doubt the validity of clinical judgment in the diagnosis of thyroid disorders.
