A trigger point is a hypersensitive spot in any muscle that has the ability to cause pain or other clinical manifestations. Trigger points can either be active or latent and can result in muscle shortness, weakness, and reduced range of motion. Let’s take a look at the difference between active and latent trigger points and how a trigger point chart can help diagnose it.
What is an Active Trigger Point?
An active trigger point means that it causes pain. Not only does it cause pain, it causes the muscles to exhibit tautness or shortening, spasm, and weakness relative to its normal state. Once the trigger points are completely eliminated the muscle will once again return to its normal strength. The longer a trigger point remains active, the more weakness occurs and the more dysfunctional the muscle becomes.
What is a Latent Trigger Point?
A latent trigger point won’t cause any discomfort unless it is sufficiently compressed. A latent trigger point is basically an active trigger point in waiting. It won’t cause discomfort unless it is activated. Latent trigger points may persist for months, even years, before they become active trigger points. While it might not be noticeable, the latent trigger point will still cause dysfunction, or prevent full motion and normal muscle strength.
