Between October, 1921, and January, 1931, I treated 7,206 private patients. Of this number, 3,541 (49.1 per cent) received some form of physical therapy, as indicated in table 1.
My equipment has consisted of: (1) a roentgen machine with an 8 inch (20.32 cm.) maximum point gap and a medium focus Coolidge tube, (2) a portable telatherm for electrodesiccation and coagulation, (3) a Kromayer mercury arc water-cooled quartz lamp, (4) an electrolytic outfit and (5) 10 mg. of radium in a half-strength flat-glazed applicator.
In roentgen treatment, the technic and measurement of dosage of MacKee1 were always used, and throughout this paper the word "unit" refers to MacKee's standard of dosage. The factors for a 1 unit dose were: 3 milliamperes, a 6 inch spark gap, a distance of 8 inches (20.32 cm.) from the target to the skin, and two minutes' time. A filter was seldom used.
