I am 78 and have had MS for 10 years. I have mainly left foot (and leg) drop and fatigue.

I have devised a cheap and simple, but very effective, “artificial muscle”. This allows me to walk with reasonable confidence whereas before I could only manage a clumsy, unpredictable shuffle.

Doctors and physios are most impressed and suggest I should patent this. Frankly, I think it is too simple to patent – besides I only want to share the idea.
