To the Editor:—
In the paper on "Diagnosis of Herniation of Lumbar Intervertebral Disks by Neurologic Signs" by Dr. J. Jay Keegan, published in the Dec. 2, 1944 issue of The Journal, reference is made to a manipulative procedure the origin of which could not be found, according to the author. May I call to your attention that this manipulative procedure was described in detail by Dr. Bror S. Troedsson in an article entitled "Lumbosacral Derangement and Its Manipulative Treatment," published in the Archives of Physical Therapy (18:10 [Jan.] 1937). Dr. Troedsson also demonstrated his procedure before the annual meeting of the American Congress of Physical Therapy on Sept. 8, 1936, when his paper was read. It seems to me that Dr. Troedsson should receive credit for the manipulative procedure so well described and illustrated in the first part of Dr. Keegan's article.
