A transient visible contraction of muscle fibers when the TrP is palpated or needled.
Activated by a "key" trigger point in another muscle; resolving the key point often inactivates the satellite automatically. Diagnostic Indicators:
Produce spontaneous local and referred pain that mimics the patient’s familiar discomfort. Trigger Point
TrPs typically arise from , which can be acute (injury) or chronic (poor posture, repetitive stress).
This report outlines the clinical and therapeutic framework of trigger points (TrPs), hyperirritable nodules found within taut bands of skeletal muscle fibers. A transient visible contraction of muscle fibers when
Physically present as a palpable nodule but only painful when compressed; they do not cause spontaneous pain.
Trigger points are primarily categorized by their activity level and location relative to other symptomatic areas: TrPs typically arise from , which can be
Pain perceived in a distant location from the palpated nodule, following established muscle-specific maps. II. Etiology and Common Locations
