Schematic of a trigger point complex of a muscle in longitudinal section. A: The central trigger point (CTrP) in the endplate zone contains numerous electrically active loci and numerous contraction knots. A taut band of muscle fibers extends from the trigger point to the attachment at each end of the involved fibers. The sustained tension that the taut band exerts on the attachment tissues can induce a localized enthesopathy that is identified as an attachment trigger point (ATrP). B: Enlarged view of part of the CTrP shows the distribution of 5 contraction knots. The vertical lines in each muscle fiber identify the relative spacing of its striations. The space between 2 striations corresponds to the length of 1 sarcomere. The sarcomeres within one of these enlarged segments (ie, contraction knot) of a muscle fiber are markedly shorter and wider than the sarcomeres in the neighboring normal muscle fibers, which are free of contraction knots.

Cross-sectional drawing shows flat palpation of a taut band and its trigger point. Left: A. The skin is pushed to one side to begin palpation. B. The fingertip slides across muscle fibers to feel the cord-line texture of the taut band rolling beneath it. C. The skin is pushed to the other side at completion of the movement. This same movement performed vigorously is called snapping palpation. Right: A. Muscle fibers are surrounded by the thumb and fingers in a pincer grip. B. The hardness of the taut band is felt clearly as it is rolled between the digits. C. The palpable edge of the taut band is sharply defined as it escapes from between the fingertips, often with a local twitch response.

Longitudinal schematic drawing of taut bands, myofascial trigger points, and a local twitch response. A: Palpation of a taut band (straight lines) among normally slack, relaxed muscle fibers (wavy lines). B: Rolling the band quickly under the fingertip (snapping palpation) at the trigger point often produces a local twitch response, which usually is seen most clearly as skin movement between the trigger point and the attachment of the muscle fibers.

Cross-sectional schematic drawing shows flat palpation to localize and hold the trigger point for injection. A and B show the use of alternate pressure between 2 fingers to confirm the location of the palpable module of the trigger point. C shows the trigger point being positioned halfway between the fingertips to keep it from sliding to one side during the injection.
