Marion, I am glad to hear that LDN is working so well for you. Congratulations!
The method I choose to increase balance, strength and get some exercise is:

Yes, a mini-trampoline. It has done wonders for me. Don't laugh, it's fun! I use a stabilizing bar for balance with it...so no falling.
I do have a question for all of you "LDNers"...
I have RRMS and don't have a lot of symptoms that you all are describing. I am still quite mobile, no bladder issues, no tremors or spasticity. My main problems seem to be fatigue, headaches and optic neuritis...but that is only troublesome when there is an exacerbation or lesion.
Does the LDN address your symptoms or the cause?
Brenda
