What may be observed during palpation of an active trigger point?

When palpating an active trigger point, one of the hallmark features you may observe is an area of increased tenderness and potential twitch response. Active trigger points are characterized by localized tenderness and can refer pain to other areas of the body when palpated. This tenderness can often be quite localized and is typically a key aspect that distinguishes active trigger points from latent trigger points, which do not elicit symptoms unless under specific circumstances.

The twitch response refers to an involuntary contraction of the muscle fibers associated with the trigger point when it is stimulated, indicating neuromuscular dysfunction. Recognizing these features is crucial for effective assessment and treatment during dry needling procedures, as addressing the tender focal points can lead to symptom relief and improved muscle function.
