Vibrating plate/machine (Edinburgh/Leith EH6)

I am looking for a decent vibrating plate/machine for myself and my disabled son to help with edema, stiffness, inflammation, and poor mobility issues please.

I would need to be able to collect it and bring it home on the bus or tram, so perhaps if it has a handle or large frame as part of it, that might need to be detachable.

If you do have one I would very much appreciate it.

Thank you in advance.
