Robotic sticks can provide arm control for children with cerebral palsy

Children with cerebral palsy may soon be using technology to gain independence. UC Riverside researchers are developing robotic sleeves that provide arm control for children with mobility issues related to cerebral palsy. Rather than augmenting the arm like an exoskeleton, the technology will use tension sensors to detect muscle contractions and predict what the wearer wants to do, such as bending the elbow. The inflatable bladders will then push the arm towards the intended destination.

Soft robotics will play an important role. Scientists construct the sleeves using elastic, nylon and other materials that will not only be more comfortable, but promise to cut costs. The creators also hope to minimize the use of electronics.

The project is still in its early stages and is expected to last four years, with the research team holding annual feedback meetings with patients, families and therapists. If all goes well, however, children with cerebral palsy will perform daily tasks like brushing their teeth without needing help from their parents or a special caregiver. Project leader Jonathan Realmuto adds that the technology is "universal": future iterations could help anyone with mobility issues, including adults.
