Cerebral palsy (CP) is a non-progressive disorder caused by abnormal development in the brain during pregnancy. CP affects one of every 1000 children globally, causing deficiencies in mobility, posture, and motor function. Spastic hand cerebral palsy, the most common form, causes hyperflexion of wrist and hand resulting in lack of motor grip and control. CP has a much higher incident rate in developing countries occurring in one of every 500 children. This affected patient population lacks the necessary treatment options to regain grip strength and motor function. Due to the fact that there are no current accessible hand orthotics for spastic CP patients in developing countries, our team will prototype, revise, and implement the accessible 3D printed hand orthotic. This custom orthotic will reduce the hyperflexion of the hand and wrist. Patient-feedback surveys on comfort, support, and usability will also help determine revisions necessary and effectiveness of the device. Designing for manufacturability and current 3D printing technology will allow the rapid implementation of the device in developing nations.
