Thanks, @unicorn7 for the video. I can't tell from it whether it is the person or the machine causing the shaking. Can you clarify whether a machine is needed, or whether you need to be someone who shakes like this spontaneously when you try to move, or is it something people are trained to do as a deliberate exercise?
No, it's the person that is shaking. You take the little tremor you get when something is heavy and you allow that to get bigger. Mostly by relaxing parts of your body. it takes so much tension out of all parts and muscles of your body, it's really nice. Looks a bit weird though

They teach you in the 4 weeks to do it properly. I would have had no idea how to do this in the way I do it now.
I did some TRE style tremors before I went there, but it is in nothing comparable.
I did like the little tremors you do with TRE, but that's just the beginning. You specifically target all different parts of your body and target specific spots that are painful, or weak of stiff etc. And then put them to use! And I think that makes it work. Not just doing the tremors, that's just a way to gain movement or strength back momentarily.
