"Medical journals from 1905 to 1915 are rife with articles on "vibratory massage" and the many things it cures. Weakened hearts and floating kidneys. Hysterical cramp of the esophagus and catarrh of the inner ear. Deafness, cancer, bad eyesight. And lots and lots of prostate problems. A Dr. Courtney W. Shropshire, writing in 1912, was impressed to note that by means of "a special prostatic applicator, well lubricated, attached to the vibrator, introduced to the rectum" he was "able to empty the seminal vesicles of their secretions." Indeedy. Shropshire's patients returned every other day for treatment, no doubt also developing a relationship with the vibration machine."
