Bicycle Design for Children with Spastic Cerebral Palsy to Enhance Interaction between Children and Parents

Cerebral Palsy (CP) is a disorder that causes a person's motor skills to become disabled. In Indonesia, the number of children suffering from CP reaches 5.5 per 1000. Although it can't be cured, their motor skills can be improved by therapy, including a bicycle for the development of their functional skills. However, according to deep interview with one of therapist in Surabaya, Indonesia, the implementation of therapy using the bike still has not received attention because it has to import from abroad or modify it by themselves. In addition, the current bicycle is still a bicycle used by the child himself so its interaction function with their parents is less achieved. The method is done by doing an in-depth interview with the therapist as well as doing observation to the target users. To test the product is done by making a prototype and usability test. This results in adding the handle to the back of the bicycle so parents can interact with the child by driving the bicycle together. It also has innovation in rear-steering and waist support mechanism that is different from previous design.
