trigger point theory
there are two characteristics of muscle pain: 1) localized pain with vague pain range, and 2) associated pain (e.g., numbness in the arm due to trigger points in the 〇〇muscle in the neck).
the brain is not good at perception
for example, when you are bitten by a mosquito in the dark at night, you can only get a rough sense of where the itch is, you can't tell where the tooth decays, you can't tell where the boil on your back is... sensation is supposed to give the brain a clear shape or image of the object you are paying attention to. However, the brain cannot recognize pain or itchiness without sight, so it senses that the source of the stimulation is too large. Under the skin (deep down), there is a mechanism to feel pain in a different place than where the pain originated.
this fact is not shared in Japan, where western medicine is the mainstream, and many people have a misunderstanding of perception.
when you see and touch it, you can recognize that this is a painful part, and only then can you feel that this is a bad part of the body. if you are bitten by a mosquito in the dark, you can feel the itchy part and know that you have been bitten and that this is the itchy part. in the case of a tooth decay, the dentist may apply cold air to the tooth, and you will feel, "that hurts!”
"what hurts?" but i may think that “there may not be a place where it hurts”.
in modern western medicine, we ask, "where does it hurt?”
the painful area is the disease area. the cause is hidden deep inside. in other words, if you want to cure chronic pain that has a deep cause, asking "where does it hurt? will not work.
therapists cannot cure chronic pain unless they start from the point of view that "the painful part is not the lesion (bad part) in many cases.
Palpate and look for sore spots.
there is a lot of misunderstanding of pain in recent years
let's take the example of osteoarthritis of the knee, which is often seen in the elderly.
the patient was diagnosed with osteoarthritis of the knee based on medical findings. however, when we checked the muscles there are trigger points were found to be the responsible trigger points, and by treating these areas, complete pain relief was successfully obtained.
what this means is that the internal joint damage confirmed by the medical findings had nothing to do with the pain. treating the inside of the joint even though there is no relationship between pain → leads to an increase in chronic pain.
where trigger points are likely to form
①Where nerves are distributed (fascia, tendon, periosteum, ligament, joint capsule, etc.)
② where stimulation is repeated (muscle-bone attachments, tendon-bone attachments, etc.)
although there are differences between clinics, in our clinic, we leave needles on the trigger points for 10 to 15 minutes after the needles are applied. after the needle is applied to the trigger point, the swollen muscles will retract and the muscles around the area where the related pain is occurring will relax.
dry needling has become the focus of attention for its effectiveness beyond anesthesia
in the 1980s, anesthesiology pain clinics in japan used to inject a small amount of anesthetic into the trigger point to provide pain relief from muscle pain. but sometimes, even without injecting anesthetics, there were cases where there was an analgesic effect as if anesthetics were injected. however, this was not understood at the time.
rom this, the interest in trigger points was born, and it has developed to the present. this type of acupuncture without injecting anesthetics or chemicals is called dry needling. in europe and the U.S., some anesthesiologists used to perform acupuncture using thin needles, but the needles cut through the tissue to insert the needles, causing significant tissue damage to the muscles.
riental acupuncture needles, which can be inserted by pushing through the tissue, attracted attention.
acupuncture needles that do not inject chemicals = dry needles. dry needling is the term used to describe the procedure.
trigger point therapy was born from the idea of dry needling. and now, research is being conducted on pain relief for pain and numbness.
myofascial pain syndrome (MPS)
trigger point acupuncture is an effective treatment for myofascial pain syndrome (MPS).
chronic stiff shoulders, back pain and headaches are caused by trigger points that form in the muscles. in most cases, numbness and pain are also not caused by bones or nerves.
even in cases diagnosed as herniated discs or spinal canal stenosis by diagnostic imaging such as MRI, the real cause of pain may be due to myofascial pain syndrome (MPS).
