3D printed walker designed for children with cerebral palsy

Cerebral palsy is the most common type of dyskinesia in children. It can be triggered by a variety of factors and manifestations are diverse. The key problem with this disease is the damage to the brain that is responsible for exercise, balance, and posture. There are currently no known treatments for this. The severity of the symptoms depends on the specific case. Mild muscles such as excessive stiffness lead to poor coordination and severe sensory disturbances. Sometimes, doctors can diagnose the early important stages of development of the cerebral palsy, but in general, the symptoms of the disease will appear early.

Although cerebral palsy is a serious disease and has not been treatable so far, more and more interventions and support mechanisms can lead patients to a complete life. In fact, many cerebral palsy symptoms are not caused by their own disability. On the contrary, it is often the case that people with movement disorders show disability for design reasons. For example, if a person can't lift his foot across a higher sidewalk, then the sidewalk makes him obstruct. If there is a curb on the sidewalk, he can go up, and the so-called disability does not exist.

Design can also help those with cerebral palsy by establishing mechanisms that provide support or treatment. Yano de Laet was born with cerebral palsy. His doctor has been paying attention to the development of 3D printing aids and has provided him with a new hands-free walker Hibbot. The walker is an ergonomic walking aid system designed by engineer Dirk Wenmakers and physiotherapist Ria Cuppers. Now, the work of Dirk and Ria has been extended to the development of physical medical robots.

Dirk and Ria got help from Materialise. Engineers from Materialise used a special software to optimize the printed parts and find the necessary parts for the walker, then print them out using their own internal 3D printer. Hibbot is a physical therapy. It not only supports the patient's buttocks and pelvis, but it also flexibly adjusts their hips and pelvis to keep their consistency as they walk. When walking, patients do not need hands, and Hibbot can exercise their muscles.

Yano's parents were very happy with Hibbot and told Materialise their expectations of their son. “We noticed that this walk was more demanding for Yano. But Yano liked it, and it was also an exercise that required Yano to concentrate and coordinate and use his muscles to walk.”

“We especially want Yano to be a happy child,” Yano’s father continued. “Despite the physical inconvenience, I hope that he will make himself as full as possible and become as independent as possible.”
