Intramuscular ligature technique is a non-invasive treatment technique that applies intramuscular adhesive tape to the body surface to enhance or protect the musculoskeletal system and promote motor function. It is commonly used in the management of various sports injuries and has been widely extended to neurological rehabilitation and cosmetology. The name comes from the prefix of the English word “kinesiology”, which is translated into Chinese as “myo-invasive”. This trade name is very consistent with the characteristics of the product which mainly works through soft tissues such as muscles, so domestic professionals are mostly called myo-invasive patch and myo-energetic patch. After years of development, the patch material and ligature technology of the intramuscular patch have been continuously improved and widely used in sports medicine in Europe, America, Taiwan, China and Hong Kong, etc. In 2008 Beijing Olympic Games and 2012 London Olympic Games, as well as in many large international events in recent years, athletes from many countries have applied this patch during the games. Qingdao Women’s and Children’s Hospital Pediatric Rehabilitation Department Zhang Qiang Patch composition The intramuscular effect patch consists of three layers, one layer is waterproof elastic cotton, the second layer is medical acrylic adhesive, and the third layer is the backing paper that protects the glue. Each square meter of elastic cotton fabric is coated with 4-70g of glue, and the glue surface is water ripple, the width of the water ripple is 3.75px, the gap is 8.75px, the wavelength is 150px, and the amplitude is 40px. Physical properties The basic physical properties of the intraosseous patch include elasticity, tension, stress, tangency and adhesion. Elasticity: the elastic retraction force of the patch itself after being stretched, i.e. centripetal force Tension: the ductility of the patch itself when it is subjected to external force, i.e. centrifugal force Stress: the antagonistic force generated by the soft tissue when it is subjected to the external force of the patch or the vertical force from the patch per unit area Tangential force: the lateral force per unit area of the patch, which can horizontally pull the skin folds towards Adhesion: the adhesive force of the patch adhering to the skin. Adhesion force: the adhesive of the patch is attached to the skin. Stretchability of the patch: 5-10% shortening and 130-150% elongation. Physiological effect: The difference in density of the adhesive tape at the time of application moves the skin, increasing the gap between the skin and the muscle, which in turn affects the flow of the subcutaneous fascial tissue, allowing sufficient permeability and circulation of the fascial system and promoting lymphatic and blood circulation. Clinical application Pain relief: According to the gate control theory, since the diameter of tactile afferent nerves (Aβ fibers) is larger than that of nociceptive afferent nerves (Aδ and C fibers), and the conduction speed is faster, increasing the sensory input to tactile afferent nerves can inhibit nociceptive input, thus reducing or eliminating pain. Improving circulation: When the patch is fitted to the skin, it naturally produces folds, which are directional and can change the flow trend of fascia and tissue fluid, effectively improving local blood circulation. Reduce edema: The pooling effect of the loose patch and the directionality of the folds of the patch direct intertissue fluid to the nearest lymph nodes, thereby reducing edema. Soft tissue support: When the natural retraction direction of the patch is the same as the direction of contraction of the taped muscle, that is, the anchor of the patch is located at the beginning of the muscle, and the rest of the patch is applied towards the muscle towards the end position of the muscle, when the patch assists the muscle contraction. Relaxation of soft tissues: When the natural retraction direction of the patch is opposite to the direction of contraction of the taped muscle, that is to say, the anchor of the patch is located at the end of the muscle, and the rest of the patch is applied towards the muscle to the starting position of the muscle, at this time, the patch can reduce muscle tightness or spasm, and moderately relax the taped muscle and local fascia. Training soft tissues: By the tactile sensory input of the patch for local skin, as the professional treatment or trainer’s hand contact guidance, can be red blood for a long time to give the soft tissues a message to induce action, can effectively enhance the training effect, to achieve the purpose of muscle re-education. Correcting posture: adjusting the tension of the muscle groups that mainly control postural movements, promoting muscle coordination ability, or further using increased tension of the patching method to fix the joint in a well aligned position, providing local joint proprioceptive input, can effectively correct improper posture. Enhancement of joint stability: It can prevent joint abnormalities caused by abnormal muscle contraction, adjust the fascia, normalize muscle function, and increase joint mobility.
