Most chronic pain has a trigger point in the muscle, which is caused by “strain” of the muscle. (Some experts and scholars believe that the muscle is not so susceptible to “strain”. (Some experts and scholars believe that the muscles are not so susceptible to strain, and that it is the fascial tissues that are susceptible to “strain”.) It is not only chronic injuries, but also trauma or overuse of a particular muscle or group of muscles that can cause pain. The presence of an excitation point is always an indication of a problem with the area or its chain of soft tissues (in this case, if it is only the muscles, then it is not rigorous enough), which manifests itself in the form of tension or pain. The creation and presence of an excitation point also always verifies that the muscles in the area are contracted. (Note that the contraction here does not have to be centripetal.) (In the literature of foreign sources, there are experts and scholars who believe that the mechanism of production of the excitation point is the continuous accumulation of a number of metabolic products inside a part of damaged myogenic fibers, which are produced partly by the metabolism of the cells in the muscle. This part of the product stimulates the nerve endings, and from them an amplified signal is fed to the muscle shuttle. The stimulus feeds back into the peripheral nervous system through weakened or convenient nerve pathways, and the impulses transmitted along the nerve pathways produce pain in particular parts of the muscle.) This passage reminds me of a client (patient) of mine! The stress-tension-pain-cycle, a phenomenon that repeats itself. That is, the elimination of the excitation point or overall soft tissue technique is better not maintained. This getting better can be months, weeks, days, or even just hours, and it comes back and does not go away on its own and is prone to scar tissue or stiff bundles of muscle fiber tension. (Because it’s hard for us to change unconscious mistakes, habit change is a conscious battle to PK the unconscious.) Its stress point exists in the tension bundles of the muscle fibers, where the small knots indicate that the myofibers in this part of the muscle fiber have been sufficiently compressed. Toward some joint sprains, muscle strains, or trauma, there is a protective mechanism in the soft tissues, and the area of injury develops some scar tissue and stiff bundles of tension in the muscle fibers, which gradually form an excitation point. Some of them are not painful, but these nodules are stubborn. When the pain flares up at some point, this stubborn nodule becomes slow to resolve or takes a long time to resolve with manipulation or exercise (e.g., physiotherapy axes “foam axle” rolling). In this case, it is effective to destroy the scar tissue formed by the old injury to create a fresh injury and then to repeat the work. Some people have pain, but this nodule is not stubborn or even noticeable. However, their increased sympathetic activity causes increased muscle tension or pain. At this point the manipulative technique manipulation brings can make the pain unbearable (at this point IQ robbing will instead be a good cure), perhaps we should find a way to inhibit the sympathetic nerve activity, and then go back to its manipulation or exercise therapy to solve it. The activity of the excitation points produces uncomfortable sensations or pain in the muscles, which constantly raises the body’s stress level, and the increasing stress level leads to further tension, which in turn makes the pain worse. Over and over again, no one can deny that problems with fascia, muscles, etc. cannot be completely resolved. Even when it has relaxed and the pain goes away, just like small joint problems, you don’t know when it happens, and it always makes you happen when or where you think it shouldn’t. Therefore, it is a problem that haunts a lifetime. And the pain triggers are latent as early as childhood. There is not one way to treat this kind of involved pain, and not one way to be perfect. It is important to realize that there is centripetal tension being shortened and centrifugal tension being lengthened. It is weak for those body tissues that are stretched by centrifugal tension. What they simply need is relaxation. Therefore, blocking the nerve impulses and sympathetic excitation in the pain area, lowering the stress level in the body, and stretching centripetal tension and relaxing centrifugal tension with some strengthening are the best solutions. Of course, these applied techniques are fundamentally different, and the performance of the target is also different. How to inquire and choose is more important at this point. The evoked test is a good means of evidence-based assessment. Of course, different parts of the different means to use different ways. For example: large and small rectus muscles, scapularis, rotator cuff muscles, pyriformis, small arm muscles, etc. …… A very important reference is the analysis of postural and motor control of daily life behavior. Here you will find that the depth (of a particular technique) is not as important as the fundamentals. Basic anatomy, biomechanics, kinesiology is the important conditions necessary for the later development of depth. Many practitioners will often say “your muscles are too tight” or “your muscles are too weak”. Tension does exist, and it manifests itself physiologically as prolonged muscle contraction, which can lead to a number of problems including pain, hyperexcitability, and functional atrophy. And the contractions, not all of them, point to cardiac contractions (being shortened). But are muscles really too weak? It’s really weak compared to athletes, and it’s probably really weak compared to you, but who are you to say that people’s muscles are too weak when their muscle strength is a normal level 5? Don’t always take the muscle strength is not as good as you, can complete the normal life exercise ability, and so on resistance to normal resistance, muscle strength level is no problem. The most embarrassing thing for practitioners is that there was once a good athlete to solve the problem of low back pain, the practitioner told him that his muscles are too weak. And this athlete humorously told this practitioner: “You say how to prove the muscle weak it, you give to do some movement test, I want to be lower than you two times can not complete, I admit that my muscle is too weak.”
