Observation on the efficacy of beryllium acupuncture in the treatment of lower limb cutaneous nerve entrapment syndrome Objective To evaluate the efficacy of beryllium acupuncture in the treatment of lower limb cutaneous nerve entrapment syndrome. Methods Seventy-two patients were divided into a treatment group and a control group. The treatment group was treated with beryllium needling, and the control group was treated with multifunctional physical therapy instrument. The efficacy of the treatment was determined according to the changes in pain, pressure and soft tissue tension of the lower limbs before and after treatment. Results The main clinical symptoms were scored and compared before and after treatment, and the difference was statistically significant with p<0.01 by t-test. Conclusion Beryllium needle can reduce the surface tension of fascia, loosen adhesions, eliminate scarring, eliminate the stimulation and compression of sensory nerve endings, and relieve pain. Lower extremity cutaneous nerve compression syndrome, that is, due to a variety of reasons caused by lower extremity ligament, fascia injury, local tension increases, stimulation of cutaneous nerve pain and other clinical symptoms in the clinical more common, and easy to be misdiagnosed, omitted diagnosis, my department since 2006 using beryllium needle therapy treatment of lower extremity cutaneous nerve compression syndrome, 36 cases, the effect is satisfactory, the report is as follows. 1, clinical data 1.1, general data A total of 72 cases of patients were treated, randomly divided into treatment group and control group, 36 cases in each group. Among them, there were 11 males and 25 females in the treatment group; the maximum age was 61 years old, the minimum age was 35 years old, and the average age was 38.5 years old. The shortest medical history was 6 weeks and the longest was 1 year. There were 23 cases of lateral femoral cutaneous nerve entrapment syndrome, 8 cases of lateral peroneal cutaneous nerve entrapment syndrome, 3 cases of saphenous nerve entrapment syndrome, and 2 cases of superficial peroneal nerve cutaneous branch cutaneous nerve entrapment syndrome. In the control group, there were 17 males and 19 females; the maximum age was 57 years, the minimum age was 32 years, and the average age was 36.8 years. The shortest medical history was 2 weeks and the longest 11 months. There were 12 cases of lateral femoral cutaneous nerve entrapment syndrome, 9 cases of lateral peroneal cutaneous nerve entrapment syndrome, 8 cases of saphenous nerve entrapment syndrome, and 7 cases of superficial peroneal nerve cutaneous branch cutaneous nerve entrapment syndrome. 1.2 Diagnostic criteria: (1) long-term chronic local pain or sensory abnormality; (2) clear local pressure points; subcutaneous nodules or striated masses can be detected locally on palpation; (3) local muscle tension without affecting body movement; (4) other neurological disorders are excluded. 1.3 Inclusion Criteria Patients who meet the above diagnostic criteria. 1.4 Exclusion criteria (1) Local soft tissue inflammatory reaction; (2) bleeding tendency; (3) suffering from serious cardiovascular and cerebrovascular diseases or organ failure can not tolerate stimulation; (4) diabetic patients with limb ischemia or soft tissue infection tendency; (5) other neurological diseases; (6) unconsciousness can not cooperate with the treatment. 2, Treatment and observation methods 2.1, Treatment methods 36 patients were applied beryllium needle treatment, every 3 days treatment, treatment 1 to 3 times. 2.1.1 Specification of beryllium needles The diameter of beryllium needles was 0.5～0.75 mm, the total length was 5～8 cm, the head of the needle was 1 cm long, the length of the body of the needle was 4～7 cm, the end of the needle was flattened with a blade, and the cutter was beveled, and the cutter line was 0.5～0.75 mm.The handle of the needles was the ordinary needle handle wrapped in steel wire and the length of the needle was about 3～5 cm.2.1.2 Methods of operation Firstly, the patients were looking for the point of pressure and pain on their lower limbs as the point of entry of the needles. After selecting the needle point, mark it with gentian violet. The local area is routinely sterilized with 2% iodine and 75% alcohol. The doctor's left thumb was pressed next to the pain point, and the right hand used the wrist force to stab the beryllium needle directly into the pressure point according to the predetermined scale, without twisting, without leaving the needle, and quickly stabbing and pulling out quickly, due to the small beryllium needle incision, it can be used in the pain point localized multi-point treatment, and after the needle was discharged, use the sterile cotton ball or gauze to press the needle hole to stop bleeding, and there is no need to cover the hole with dressings. 2.2 Physiotherapy control group Multi-functional therapeutic instrument treatment 5 times a week, each time 20min, treatment 1 ~ 2 weeks. 2.3, Observation methods Mainly judge the changes of pain, pressure and soft tissue tension before and after treatment. 4, Discussion Dermal nerve entrapment syndrome refers to the nerve dysfunction caused by chronic entrapment of the dermal nerve in the course of its course due to some reasons, and shows a series of different degrees of sensory disorders, phytoneurological dysfunction, trophic disorders, and even motor dysfunction of a series of nerve distribution zones [1]. Most of the patients due to various reasons so that the limb for a long time to maintain in a posture that makes the nerve compression or damage immobile or work in the nerve repeated compression, or traumatic injury so that the ligament, fascia due to injury and bleeding, inflammation and swelling, scar formation, local tension increase and other pathological changes, so as to extrusion stimulation of through the dermatomal nerves, which in turn appear pain and other clinical symptoms. This kind of disease has become a frequent and common disease that is not emphasized and easily misdiagnosed. Beryllium needles originated from "Ling Shu? Nine needles", the book recorded "the name of the nine needles, each different shape ......; ...... five said beryllium needle, four inches long, wide two and a half minutes; ...... beryllium needles, the end of the sword blade, in order to take large pus. Sword sharp, in order to take the big pus", the modern beryllium needle synthesize the advantages and disadvantages of the past various therapies, choose a new material titanium alloy developed into a modern beryllium needle, [2] it is based on the skin nerve pressure caused by the characteristics of the state of the soft tissues of the design of the development of the nerve card pressure has dredged the meridians and collaterals, regulating qi and blood, improve local microcirculation, and promote the local congestion and edema of the subside and absorption of the sterile inflammation, and make the pressure in the fascial cavity to reduce, and make the fascial cavity to reduce the pressure, and make the fascial cavity to reduce the pressure. It also reduces the pressure in the fascial cavity and the tension on the surface of the fascia, so as to achieve the dual purpose of loosening adhesions and decompression and hypotension, [3] thus obtaining ideal clinical efficacy. Firstly, beryllium needles are applied to the local pain points for multi-point stabbing, cutting the subcutaneous tissues, fascia and muscles of the lower limbs, so that the pressure in the lower limb fascial cavity is released, and the surface tension of the fascia is lowered, thus eliminating the stimulation and compression of the sensory nerve endings and relieving the pain to achieve the purpose of decompression and decompression, and secondly, through the decompression and decompression of the local soft tissues, it can change the circulation of the tissues of the diseased area and accelerate the absorption of the inflammatory metabolites. accelerate the absorption of inflammatory metabolites, thus fundamentally eliminating the pathological basis of causing neuroinflammatory damage and pain [4]. In addition, beryllium needles also have the effect of dredging and adjusting meridians like acupuncture [5]. At the same time, due to the small tip of beryllium needle, the intraoperative damage to the lower limb cutaneous nerve and surrounding tissues is small, so the local formation of scar is less, and it is not easy to form again the cardinal pressure, which can make the clinical symptoms get obvious improvement. The above clinical treatment was evaluated by using nimodipine method to assess the changes of pain, pressure and soft tissue tension before and after the treatment, and the results showed that beryllium needle can fully loosen the adhesion and release the compression, which is a safe, simple, sure efficacy, and easy to promote the new treatment, which has the advantages of small incision, little pain, no need for anesthesia, accurate positioning, and more adequate loosening.
