Physics applied to post-stroke rehabilitation Shoulder Soft Robotics Brace December 31, 2011 report

I wonder how much difference between this and the one from the UK here:

The new one here:

Abstract
Imagine a world where orthotics are not simple passive supports for physically challenged people, but rather
highly cooperative, smart devices. They are lightweight and simple to don and doff, respond to the user’s
intent and enable normal healthy limb like use. They can help users relearn natural movement pathways
following stroke and injury, or provide exercise tailored to the user’s specific disabilities.
A new generation of soft and active orthotics is proposed for a broad range of applications in physical
therapy and rehabilitation. As part of the AIP SPS funded project, we began development of such orthopedic
braces through physics based biomechanical simulation, human subject experiments, data analysis and
experimentation with a biologically-inspired shoulder-arm model and a preliminary sensor network. A joint
work with collaborators at the Harvard University shows that the proposed braces can be successfully
actuated with biologically-realistic forces [1]. Furthermore, our recent results demonstrate that arm angular
position can be accurately estimated with embedded inexpensive, piezoelectric flex sensors and IMUs.
Finally, we report results of our neuro-sensory-motor control experiment and we report on the first fully
functional prototype of the two “muscles” shoulder soft robotics brace.
