Pain in patients with cerebral palsy (CP) is a major health issue strongly associated with reduced quality of life. In this study, we provide an overview of pain conditions in children with CP using the International Classification of Diseases, 11th Revision (ICD-11), which has been updated with a classification of chronic pain. Common causes of pain in children with CP, including hip displacement, muscle spasms, and procedures, are discussed; less studied pain types including headaches, neuropathic pain, visceral pain, and acute versus chronic pain are also highlighted. The addition of chronic pain to the ICD-11 is an important step forward in optimizing both the registration and assessment of pain conditions. However, a tool designed specifically for the different types of pain in patients with CP is imperative. In this paper, we propose a Cerebral Palsy Pain Classification that is aligned with the underlying mechanisms of pain and the ICD-11 pain classification.
