Would it help for someone who had a stroke?

Not sure if it would or not a neighbour of my parents had a stroke which paralyzed one half his body. Depending on the extent of your stroke. I would imagine. I am of course no neurologist. But as a heart patient. IF you can lift it be it a weight or anything that can strengthen any joint. or if you can squeeze it ..use the hand gripper..and the finger guitar type thing in this group..the hand gripper adjusts to various strengths ..meaning not just one level by the knob on it . so very different than that of those you find in the stores. and just between finger and another at the lower settings. on the tip ends of the handles It would not hurt to try.
