The goal of this interventional study is to learn about the biomechanical factors underlying the beneficial changes in children with cerebral palsy after using individually-adapted stand-on ride-on power mobility devices (PMD). The main questions we aim to answer are: * How does the use of stand-on PMDs affect static balance in children with cerebral palsy? * How does the use of stand-on PMDs affect dynamic balance and mobility function in children with cerebral palsy? Children ages 4-6 years old with cerebral palsy (GMFCS levels II and III) will: * Use individually-adapted stand-on PMDs for three months. * Undergo tests to measure static balance, dynamic balance, and mobility function before and after the intervention. * Receive a full biomechanical assessment (kinematics, kinetics, muscle activity, gait spatiotemporal characteristics). Researchers will compare pre-intervention and post-intervention measurements to quantify improvements in balance, muscle activation, and mobility.

Children will receive the adapted toy car (individually-adapted stand-on PMD) to take home and use for three months. PMD will be used at their house and familiar environments to the family (e.g., neighborhood, parks, schools).
