New Technology I: Helping Paraplegics and Quadriplegics to Walk

Several companies are working on technology to enable people with spinal cord injuries to walk again. Dave MacCalman, a New Zealand Paralympian with a cervical cord injury, recently purchased a robotic exoskeleton from Rex Bionics. This device allowed him to walk for the first time in 30 years. 

This exoskeleton is somewhat bulky (84 pounds), and allows only slow movement. The unit does not use crutches, but does require a modest amount of arm strength to use. It allows walking up slopes and building standard stairs with a handrail. To go down stairs, the user steps down facing backwards. The power supply lasts 3-4 hours.

This technology has only been in development for nonmilitary use for a few years. I expect that great strides (!) will be made as more companies join the fray. Tomorrow I’ll feature an exoskeleton from a US company, and point out the pros and cons of the two devices.
