A long time ago when EMS (electrical muscle stimulation) first came out, it was athletes only stuff used in sports medicine. Then physical therapy departments started catching on to it's benefits and began using it with people with various injuries. Then exercise places started offering it for actual exercise.
There was a lot of consternation about whether it was "the easy way out for fat people to exercise without working out" and the exercise places stopped using it due to cost and the need for people to be certified in it's usage in those places. My grandmother was disabled and needed a chair to get around.
EMS, balance training and the variations her PT came up with, including what they both called "The Tipsy Chair" that the PT designed gave her an enhanced quality of life and movement that she didn't have before. Anyone who thinks these things don't work should have seen my Nannie!
As long as it gets you moving and is properly used, you get a benefit.
I'm glad you are seeing benefit from this, Marion! Keep up your hard work and keep us updated on your progress!
