First off I do not know who invented it. However I used to sell them. I would telephone possible clients to make an appointment in the privacy of their own homes.
I was told by the company that originally it was invented to help exercise paralyzed people. Then the opportunity for people who were not injured to use for exercise without the real work. Also the United States Navy made use of them for submarine sailors to get their workouts in cramped quarters when they were under the Polar cap. There were Magazine articles about this. If I remember correctly one of those boats was named the Skate. Also they were advertised in the most expensive magazines like Glamour & others.
I used the machine myself and it did move muscle. You could feel your muscles contracting. I never did find out why they were banned.
