Physiotherapy Physiotherapy is widely used in clinical practice, and has important practical value in treating and preventing disease and restoring function, often playing a role that other therapies cannot. In the treatment of lumbar disc herniation, it can also play an important auxiliary role. (1) Analgesic effect. Pain is one of the main symptoms of lumbar disc herniation, manifested as lumbar pain radiating unilaterally or bilaterally to the lower limbs. Various heat therapy and electrical stimulation therapy in physical therapy can relieve pain and can play a role in symptomatic treatment. (2) Anti-inflammatory effect. In patients with lumbar disc herniation, local inflammatory reactions often occur due to rupture of the fibrous ring or compression of the nerve root by the herniation. Heat therapy, short wave, ultra-short wave, infrared and other physiotherapy means have the effect of promoting the inflammation to subside and absorb. (3) The role of loosening adhesions and softening scars. Physiotherapy can loosen adhesions caused by various reasons, especially for the recovery of patients with lumbar disc herniation who have received surgical treatment. (4) The effect of excitation of nerves and muscles. Untimely treatment of lumbar disc herniation can cause numbness and muscle atrophy in the lower limbs due to prolonged nerve root compression. Low and medium frequency electrotherapy can stimulate the excited nerves to repair and regenerate, or make electric gymnastics to make muscle excitement and contraction, and also promote sensory recovery Electrotherapy treatment (1) direct current and drug ion introduction method. Direct current therapy is the use of low-voltage, smooth direct current action on the body to treat disease methods. DC has positive and negative polarity, electrolytic effect, through the body, can produce a series of physical and chemical changes in human tissue, tissue metabolism, peripheral circulation and the nervous system have certain effects. Especially when combined with drug ion introduction, it can make the drug components enter the tissue interstices, so as to achieve the effect of relaxing the tendons and activating the blood and relieving pain. (2) Low-frequency electrotherapy. The main function of low-frequency electricity is to excite motor nerves and muscles through current stimulation to restore normal function, and also stimulate sensory nerve endings to promote sensory recovery. In the treatment of lumbar disc herniation, it can be applied not only to lumbar pain, but also to the restorative treatment of lower limb numbness and muscle atrophy caused by nerve root compression. Low-frequency electrotherapy specifically includes induction electrotherapy, interkinetic electrotherapy and electroexcitation therapy, each with its own characteristics, which can be used flexibly in clinical practice. (3) Medium-frequency electrotherapy. Medium-frequency electricity is easier to reach the deep part of the tissue through the skin than low-frequency electricity, which has the functions of analgesia, promoting local blood circulation, excitation of skeletal muscle and smooth muscle, etc. Among them, audio electricity can stimulate the adhesion tissue through electric current to make it vibrate and get loosened and softened, which has certain effect on the radicular adhesion caused by lumbar disc herniation. (4) High frequency electrotherapy. High-frequency electricity has no polarity and no excitatory effect on nerve muscles, it mainly relies on thermal effect for treatment. This thermal effect is deeper and more uniform than that of conduction heat or radiation heat, which can make deep tissue congestion, improve circulation, reduce central and peripheral nervous system excitability, and enhance leukocyte phagocytosis. High-frequency electrotherapy includes short-wave, ultra-short-wave and microwave electrotherapy, all of which have certain analgesic and anti-inflammatory effects on lumbar disc herniation. Drug ion introduction method of treatment The use of direct current electrotherapy ion introduction method of treatment of lumbar intervertebral disc herniation, should also be in accordance with the principles of Chinese medicine diagnosis and treatment of drug selection and prescription. Two groups of prescriptions are commonly used: (1) to relax the tendons and activate the collaterals, dispel wind and remove dampness, the drug composition is: Gui Zhi, Chuan Wu, Cao Wu, Gentiana, Mu Gua, Tian Nan Xing, Qiang Wu, Dou Wu, Angelica, 20 grams each, Gong Ying, Wei Ling Xian, 30 grams each, water decoction. (2) Based on the principle of relaxing tendons, activating blood circulation and relieving pain, the drug is composed of 20 grams each of Gui Zhi, Chuanxiong, Angelica, Safflower, Dang Pi, Gentiana, Papaya, Qiang Wu, Boswellia, Myrrh, and 30 grams each of Stretching Tendon grass, Radix Rehmanniae, Haitongpi, and Gong Ying. Decocted in water and set aside.
