Spoilers: Women working on pedal driven sewing machines were complaining of back pains. An alert medical professional also discovered that the women were getting off by the leg movement that drove the machine. Clearly, it was this immoral behavior that was the cause of their back pains.

Pretty remarkable that this line of reasoning was accepted by the brightest and best educated minds only 150 years ago.
