Pin on Nothing Ever Really Dies Biology Diagrams Trigger points (TrPs) or muscle "knots" are sore spots in soft tissue that cause deep aching. Myofascial pain syndrome (MPS) is a chronic pain disorder of too many trigger points. TrPs are usually described as micro-cramps, but the science is half-baked and their nature is controversial.Regardless, these sore spots are as common as pimples, often alarmingly fierce, and they seem to grow
Variation was observed in two MTrPs: point 3 presented two nervous entry points, designated MTrP3 and MTrP3.1, and point 5 presented three different patterns, designated MTrP5, MTrP5.1, and MTrP5.2. MTrP1 was situated in the intermediate part of the anterior border of the upper part of the muscle, as described previously (Figures 1 and 2 ). A trigger point is due to sensitized sensory nerves within a taut band of a muscle that when squeezed generates local and referred pain. The cause of a taut band is a hyperactive motor nerve branch, which generates sustained contraction in the muscle fibers attached to the motor endplate that the nerve branch supplies. Simply put, a trigger point is defined as a hyperirritable spot found along a taut band of muscle. The trigger point may cause pain following compression, stretching, or excessive or lengthy stimulation. Each muscle has areas that are predisposed to trigger points; it is even possible to find several of them in the same muscle. A trigger point

8 Characteristics of Trigger Points. Palpable Nodules: Trigger points are often felt as small, hard nodules or knots within the muscle tissue. Tightness: The muscle tissue around a trigger point is often tight and contracted. Pain: Referred Pain: Trigger points can cause pain in areas distant from the actual site of the trigger point. The trigger point explanations are excellent from Dr Gerwin. Love how he explains the various needling techniques and positions for the same Trigger point, multi-dimensional. All Musculoskeletal practitioners should have this. It is very patient compliant and helps patients understand pain patterns with trigger points. Well done very impressed!
Anatomy and Etiology [edit | edit source] Trigger points develop in the myofascia, mainly in the centre of a muscle belly where the motor endplate enters (primary or central TrPs). Those are palpable nodules within the tight muscle at the size of 2-10 mm and can be demonstrated at different places in any skeletal muscles of the body The X's represent the Trigger Points. The red dotted area is the referred pain caused by the Trigger Point and the solid red means more people experienced pain in that area. The dark green color areas represent the muscles of the human body. The trigger points these cause are a major cause of headaches. For more information please see: Self massage and trigger point therapy for headaches and migraines. Example three: trigger points themselves cause muscle tightness. As discussed above trigger points cause muscles to tighten.
