Exoskeleton builds muscle capacity, improves posture in cerebral palsy

Thomas Bulea and NIH colleagues have developed a robotic exoskeleton for children with cerebral palsy.

“Crouch gait,” where a person walks with a perpetual bend in their knees, is a hallmark of the disease. This damages muscles and joints and  results in  paralysis for half of cerebral palsy patients.

Bulea believes that increasing the amount and intensity of gait training  is key to successful outcomes.  The exoskeleton  is  meant to strengthen  muscles when children are learning to walk,  instead of treating the problem when its already progressed into adulthood.

7 study participants  were able to walk with the exoskeleton ,without the help of other  devices, and without relying on the robot entirely.  Their muscle capacity and posture improved.

According to Bulea: “We do a lot of things early on that weaken their muscles — cut their tendons, inject them,” she said. “We’re trying to come up with solutions that are win-win. … Training them to stay more upright that will keep them walking longer, that’s our pie-in-the-sky goal.”

The next step is to make the system lighter,  and independent of a grounded power source, so that it could be used at home
