What is a trigger point?

A trigger point refers to an area of tenderness in a tight band of muscle. It is a localized spot, often within a muscle, that can cause pain in the muscle itself or refer pain to other areas of the body. Trigger points develop due to muscle overuse, stress, or injury, leading to muscle tightness and discomfort. They can often be palpated, meaning they can be felt as tender knots under the skin.

Understanding trigger points is essential in sports medicine and rehabilitation, as they can significantly affect an athlete's performance and contribute to chronic pain. Recognizing and treating these areas can aid in restoring normal function and alleviating discomfort. The process of identifying trigger points is crucial in therapeutic techniques such as massage therapy or physical therapy, which focus on releasing tension in the affected muscles.
