The importance of sacro-iliac strain or relaxation in the production of partial invalidism has been recognized for several years. The frequency of occurrence and the persistence of pain and discomfort incident to relaxation of the sacro-iliac joint following childbirth, prolonged illness, and also from excessive pelvic strain and distortion, has necessitated the devising of a more efficient type of support than has hitherto been obtainable, that is, one which can be worn continuously and maintained in the proper position. The greatest difficulty that has beeen experienced in the use of previously devised types of support, including the various belts, braces, etc., has been the maintenance of sufficient continuous support over the sacroiliac joint.
While I claim no originality for the type of support herewith exhibited, I have never seen another just like it. However, should other identical devices be in existence, I can recommend them most highly in the treatment
