Hi Connie!
I glad to read that the test I was refering to helped you in quantifying your problems. And yes, 60-70 is a rather good score, I told you my lowest was 32, but at that time I had generalized MG which means that nearly all muscles were weakened. Partial good scores indicate that these functions are not affected and repeating the tests after a while will quantify the evolution, which I hope will be positive.
Maurice.
