3D rehabilitation system to improve arm function following stroke

If you follow this thru the the full PDF you can see pictures of what they are doing, electrical stimulation with a supported arm.

Abstract
In the September/October 2009 issue of Progress in Neurology and Psychiatry, we featured an article describing a promising new 2D robotic and electronic stimulation system developed at the University of Southampton for rehabilitation of arm movement following stroke. Here, the scientists who developed the system describe a further extension of the technique to a new 3D system known as SAIL (Stimulation Assistance through Iterative Learning).

I really question the results being from the 3d part, Looking at the setup you can see that the arm is totally supported. That de-weighting of the arm is what I believe allows the patient to focus totally on the muscles necessary for the specified movement rather than needing to focus on shoulder muscles to hold up the arm. And I've already posted on the issues with even this kind of limited multitasking for survivors.
