How is myofascial pain diagnosed?
The recognition of this syndrome requires a precise understanding of the body's trigger points. Trigger points can be identified by pain that results when pressure is applied to an area of the patient'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.
