This is a protocol for a Cochrane Review (prognosis). The objectives are as follows:

We aim to describe the overall prognosis (focusing on the pain course) and the negative impact(s) of acute and chronic musculoskeletal, widespread, and neuropathic pain in children (aged six to 12 years) and adolescents (aged 13 to 18 years) by evaluating:

incidence of pain recovery at three and 12 months after reporting acute or chronic pain;

change in pain severity at three and 12 months after reporting acute or chronic pain; and

negative impact(s) of pain at three and 12 months after reporting chronic pain.
