Below is information about headaches and physical therapy, as described by the American Physical Therapy Association.
Headaches, like back pain, are one of the most common of all physical complaints and can be one of the most frustrating to manage. Pain of any type that occurs in any part of the head is called a headache. Tension-type headaches (also called muscle-spasm headaches) are the most common types of headaches in adults. They may be the result of a neck or jaw problem, poor posture, fatigue, or stress. A problem in the neck, head, or jaw--such as an injury or arthritis--can lead to tension in the muscles at the back of the head and to increased pressure on the nerves to the face and head. Poor posture can cause these muscles to become overworked, which can trigger a headache.
