Hi,

Yes, in the early stages of PT after the arm break, they were the main thing that relaxed everything well enough to stand the exercises. But I had to modify them, so I used cold water, interchanged with moderately hot water.

Oh yes, the other thing that really helped was paraffin wax..but I don't have a "home" wax heater thingy, so I only had those at the PT place. Wish I did have one, specially for the cold weather, (yes, it's gone cold in Hong Kong..) they are *wonderful*!
all the best
