Now this is interesting: a powered exoskeleton for paraplegics

ReWalk™ is a man-machine device where the user is actively involved and has control of all mobility functions, through unique control processes. Walking is controlled through subtle changes in center of gravity, stability and safety are secured by use of crutches. Participation in mobility control comes naturally and intuitively, and brings tangible health and emotional benefits. ReWalk™ is not just a vertical wheelchair – ReWalk™ restores the element of control over mobility so lacking for wheelchair users. As any wheelchair user can attest, life in a wheelchair carries a hefty healthcare price tag. Serious problems with the urinary, respiratory, cardiovascular and digestive systems are common, as well as osteoporosis, pressure sores and other afflictions.

By maintaining users upright on a daily basis, and exercising even paralyzed limbs in the course of movement, ReWalk™ alleviates many of the health-related problems associated with long-term wheelchair use. In addition to relieving suffering, this has a real impact on healthcare costs – cutting, and enabling both insurers and individuals to redirect funds to other avenues. Adoption of ReWalk™ by wheelchair users results in significant cost saving at both institutions and private homes. ReWalk™ makes standing devices, stair lifts, bed lifts, and other mobility assistance apparatus redundant. Similarly, ReWalk™ users don’t require expensive powered wheelchairs – or the oversize vehicles and devices required to handle them. With ReWalk™, users require only minimal additional mobility assistance – dramatically increasing independence together with cost saving on a yearly basis.
