What are trigger points in the context of dry needling?

Trigger points are defined as specific areas of hyperirritability in skeletal muscle. These points can be palpated as taut bands of muscle and are often associated with localized tenderness and referred pain. When stimulated, trigger points can elicit pain in other areas of the body, making them significant targets in the practice of dry needling. The goal of dry needling is to deactivate these trigger points to alleviate pain and improve muscle function.

Understanding the nature of trigger points is crucial as it highlights their role in muscle dysfunction and pain syndromes. Proper identification and treatment of these areas can lead to significant relief for individuals suffering from musculoskeletal pain conditions. This concept is foundational to dry needling, as targeting these hyperirritable spots helps to promote muscle relaxation and restore normal function.
