Best practices from acute-care hospitals shed light
   on better transitions between levels of care.

                      and his physicians and nurses knew it. A man in his 50s with C-2
                      quadriplegia, he was dependent on a ventilator and had a history of
                      pressure ulcers. In fact, a couple of times during his stay at Shepherd
                      Center in Atlanta, he was rushed into the intensive care unit and required
                      cardiopulmonary resuscitation.
                       Yet nine months after discharge, the patient had defied the odds. Thanks
                     to careful planning and education, the patient and his family handled the
                     inevitable health issues without a single hospital admission.
     Preventing hospital readmission is a challenge when caring for patients with the
    complex medical consequences of spinal cord injury (SCI) or traumatic brain injury (TBI).
    But it is also an imperative, especially as payers shift to reimbursement for outcomes
    rather than services.

                          or some people with spinal cord injury (SCI), powered exoskeletons
                     promise a great leap forward in mobility and a range of related
                     physiological and psychological benefits. But designing a device that
                     is compact and lightweight enough to promote independence, yet still
                     affordable enough for widespread use, has proven to be a challenge.
                          A new device produced by a team of engineers at Vanderbilt
                      University in Nashville in collaboration with clinical personnel at
                      Shepherd Center in Atlanta, may be a breakthrough in the field. The
                      Vanderbilt exoskeleton weighs just 27 pounds and can snap apart to fit
     into a backpack. Unique among such devices, the exoskeleton is designed to allow a
     person with paraplegia to carry the device to a public place on the back of a wheelchair,
     assemble it, put it on, take a walk and return to a wheelchair without assistance.

     The Vanderbilt exoskeleton is the first of its kind to incorporate       notes. That profile includes some people with SCI as high as

        “This device has real functional possibilities in the home

     great promise as a gait training device, especially the FES
     component. Incorporating FES into gait is a huge advantage.”
