Acupuncture treatment of scars

2022-06-07 0 By

Current conservative scar treatments, such as pressure suits, silicone gel, topical creams or gels, and massage, have a positive impact on scar redness, thickness, and flexibility.However, their ability to affect pain and itching is limited.In various studies, positive results were achieved with acupuncture to treat scar tissue, improve scar quality and relieve pain and itching symptoms;However, the effect varies with treatment frequency, duration, number of treatments and acupuncture points.In traditional Chinese medicine, scar tissue has the ability to block qi and blood, showing the characteristics of bleeding stagnation.In biomedicine, scar tissue may cause adhesions between the skin layer and connective tissue (fascia), resulting in circulatory disturbances in the area around and adjacent to the scar.During exercise, due to pressure and stretching, thicker scars may be more likely to activate mechanically sensitive motion receptors, and mechanical stimulation of sensory receptors induces the release of neuropeptides, which further stimulates chemically sensitive nociceptors and leads to neurogenic inflammation of scar tissue, damaging and prolonging the healing process.Thus, increased scar thickness, decreased flexibility, and increased nociceptor density may be associated with abnormal tissue healing, leading to symptomatic, slow maturing scars.Acupuncture stimulates mechanoreceptors and nociceptors in the skin and underlying tissues and is thought to increase the activity of inhibitory neuromediators, thereby regulating neurogenic inflammation.Acupuncture, as an invasive technique, causes much less local tissue damage due to the narrower needles it uses and the advantages of specialized targeted therapy.Acupuncture for scars and problems that arise reduces sensitivity and abnormal color of scars and resolves or greatly improves problems that arise after treatment.Acupuncture textbooks for deep and shallow needling provide recommended ranges of needling depth, mainly for safety reasons.The depth of acupuncture is considered to be a factor affecting the curative effect of acupuncture.There was no significant difference in brain area activation between shallow and deep stings in healthy subjects, but deep stings affected more abnormal brain areas than shallow stings, especially in the hippocampus.The physiological mechanisms associated with the effect of piercing can be explained in terms of the structures affected by the needle: skin, muscle fascia, and muscle.At deeper levels, acupuncture may interact better with ascending neural pathways than cutaneous afferents.Shallow punctures stimulate collagen fiber remodeling, which reduces scar thickness and improves the appearance of scarred skin.The Angle of insertion of straight and oblique needles can affect the patient’s perception.Sensation tends to propagate along the insertion direction.The body undergoes the insertion of the needle down from the surface of the skin, so naturally the senses follow the insertion path as it progresses.This means the needle can be pointed to the area where the treatment is needed.If an area of adhesion is to be cleared, a needle can be inserted far from the point to encourage more subcutaneous space.To achieve therapeutic results, acupuncture needles need to be operated manually after being inserted into the body.Before and after acupuncture operation usually include needles rapidly spinning (or one-way) and/or piston movement (movement up and down) on animal studies have shown that in order to response the mechanical stimulation, local connective tissue fibroblasts to active cytoskeleton remodeling, the fibroblasts mechanical induced reaction accompanied by autocrine/paracrine purine can signal inducing analgesic action.Manual acupuncture needle rotation within the connective tissue plane can result in the winding or local stretching of collagen fibers around the needle, resulting in mechanical signals.Potential effects include the synthesis and release of growth factors, cytokines, enzymes and structural components of the extracellular matrix.The rougher the surface of the needle, the more effective the treatment.During rotation, connective tissue wraps around the acupuncture needle, creating a tight mechanical coupling between the needle and the tissue.This needle-tissue coupling allows the needle to move further (rotating or piston motion) to pull and deform the connective tissue around the needle, thereby transmitting mechanical signals to the tissue.In traditional Chinese medicine theory, the needles are generally left for 15-30 minutes to increase the stimulation of acupoints and the body.Sometimes there is no needle, so called fast needle.In the literature, there are no relevant studies on the efficacy of needle retention.But one particular form of acupuncture, called Hari, originated in Japan.Used mainly in Korea and Japan, it involves placing needles permanently in large muscle groups to try to provide sustained pain relief.However, the clinical effects of this technique are also not well documented.Studies on acupuncture and moxibustion in the treatment of pruritus have shown that local application of acupuncture and moxibustion to the pruritus site or the same ganglion segment (dermatome or sarcomere) can relieve pruritus.Correspondingly, distant needle placement had minimal impact on humans and animals (as assessed by scratching response).Local and segmental acupuncture stimulation will provide the same sensory input to segmental spinal nerves as the itch sensation.Therefore, acupuncture can modulate signals at the level of the dorsal horn, reducing the intensity of harmful signals sent to the central nervous system for processing.The physical properties of the scar, including thickness and color, were improved after acupuncture treatment.The sarcomere and cutaneous segments in the trunk overlap in the same vertebral segment because they present innervation of the anterior and posterior branches of the spinal nerves.The posterior dermis is innervated by the posterior branches of the spinal nerve.At a deeper level, the structure of the sarcomere is dominated by the same posterior ramus of the spinal nerve, as opposed to the deep and muscular fascia, which are derived from differential isomers.In the lateral and anterior regions of the trunk, the skin receives innervation from the anterior ramus of the spinal nerves.Again, it occurs when motor muscles and fascia develop through the pituitary gland.
