Development of Orthosis Design for Spastic Cerebral Palsy Through Biomechanical Approach

CP patients in Indonesia is estimated at around 1-5 per 1,000 live births to 80% is a type of Spastic CP. In patients with Spastic CP legs stiffness that causes the formation of abnormal posture, walking gait, and decreased motor skills which can be treated by wearing the orthosis. HKAFO often used as a device for therapy and AFO used for daily. Control posture patients in daily activity be the most important point in increasing gross motor function. To maximize the use of orthosis for daily activity needed design development with the approach biomechanical aspect. Approach which includes power of motion feet, angles motion joints, and adjustment to the different character of CP Spastic.
