is a term used to describe a group of chronic conditions affecting body movements and muscle coordination. It is caused by damage to one or more specific areas of the brain, usually occurring during fetal development, or during infancy. It can also occur before, during or shortly following birth. "Cerebral" refers to the brain and "Palsy" to a disorder of movement or posture.

Chiropractors infer a causal relationship between nerve interference or compression at the spine and subsequent problems in more distant body parts or organ systems connected by the nerve.

In anatomy, the ankle, or ancle (a word common, in various forms, to Teutonic languages, probably connected in origin with the Latin angulus, or Greek αγκυλος, bent), is the part of the lower limb that is located between the foot and the leg, and is actually comprised of two separate joints: the talocrural joint (or "true" ankle joint) and the subtalar joint.

Acute pain, such as occurs with trauma, often has a reversible cause and may require only transient measures and correction of the underlying problem. In contrast, chronic pain often results from conditions that are difficult to diagnose and treat, and that may take a long time to reverse. Some examples include cancer, neuropathy, and referred pain. In such situations, the pain itself is frequently managed separately from the underlying condition of which it is a symptom.

Rheumatologists mainly deal with problems involving the muscles and/or joints.
