Identifying and injecting myofascial trigger points.
Myofascial pain syndrome is characterized by the presence of discreet, hypersensitive nodules known as trigger points. A myofascial trigger point is a hyperirritable locus within a taut band of skeletal muscle, located in the muscle and/or fascia (1). They are palpable within muscles as cord-like bands within a sharply circumscribed area of extreme tenderness. Trigger points are found most commonly in muscles involved in postural support.
