How Muscle Pain Is Diagnosed
Trigger points can be identified by pain that results when pressure is applied to an area of a person's body. In the diagnosis of myofascial pain syndrome, four types of trigger points can be distinguished:
- An active trigger point is an area of extreme tenderness that usually lies within the skeletal muscle and which is associated with a local or regional pain
- A latent trigger point is a dormant (inactive) area that has the potential to act like a trigger point.
- A secondary trigger point is a highly irritable spot in a muscle that can become active due to a trigger point and muscular overload in another muscle.
- A satellite myofascial point is a highly irritable spot in a muscle that becomes inactive because the muscle is in the region of another trigger pain.
