Spastic diplegia is a very common subtype of cerebral palsy (CP), and CP itself is the most common cause of childhood-onset physical disability. An estimated 17 million people worldwide have CP. Spastic diplegia is also known as bilateral spastic CP or, simply, bilateral CP.  With spastic diplegia, the lower limbs are much more affected than the upper limbs, which frequently show only fine motor impairment. Now in its second edition, this practical guide addresses spastic diplegia across the lifespan and the evidence-based, best-practice treatments. It also includes the lived experience of families.  The writing of Spastic Diplegia was led by Lily Collison, MA, MSc, the parent of a son with spastic diplegia. The first edition of this book gave rise to the Gillette Children's Healthcare Series , a series of books for families who are looking for clear, comprehensive information. Health care professionals, educators, students, and extended family members will also benefit from reading Spastic Diplegia .  Other titles in the series include: Craniosynostosis Idiopathic Scoliosis Spastic Hemiplegia–Unilateral Cerebral Palsy Spastic Quadriplegia–Bilateral Cerebral Palsy Epilepsy Spina Bifida Osteogenesis Imperfecta Scoliosis: Congenital, Neuromuscular, Syndromic, and Other Causes
