Cerebral palsy (CP) is a nonprogressive condition as to its etiology and neuropathogenesis. However, health and function may deteriorate as patients with CP grow older. Problems secondary to “growing” may develop in muscle tone, motor, and postural control. Movements or postures adopted to compensate for these abnormalities may result in further disturbances affecting health and functional state. Although appropriate medical management, rehabilitation, adaptive strategies, recreational activities, and assistive technology allow most individuals with CP to participate in social events, develop skills, find jobs, and live an independent and active life, many need more assistance and care in adulthood. Aging and CP can be a difficult combination where collaboration is strongly needed between disciplines in order to generate evidence for guiding clinical practice and establish appropriate systems for care. Physiotherapy and rehabilitation programs in CP vary based on the individual’s age and functional status. The physiotherapy, rehabilitation, and terms of physical and motor functions are reviewed in this chapter.
