Residents in wheel chairs can easily pick up their Diodatics from the floor and not worry about them rolling away, like a dumbbell. 

Residents combined to their beds, also, can  benefit from a Diodatics Workout (with proper supervision).

 The Diodatics are especially great for people with arthritis in their hands because they don't have to worry about gripping the weight.  The dumbbell only has one grip whereas the Diodatics offers 6 different ways to comfortably grip.
