Cervical spondylosis is a common and frequent disease among middle-aged and elderly people, and in recent years there has been a trend of rejuvenation, especially among long-term head-down workers. It is mainly a clinical syndrome with different symptoms caused by degeneration and protrusion of the cervical disc, relaxation of the joint capsule, instability of the inner balance, loss of the physiological curvature of the cervical spine and osteophytes, resulting in narrowing of the intervertebral space and narrowing of the spinal canal, squeezing the nerve roots, spinal cord and surrounding tissues of the cervical spine. The clinical manifestations of cervical spondylosis are complex and vary according to the location of the lesion, the compressed tissue and the severity of the compression. It can be roughly divided into: nerve root type, spinal cord type, esophageal type, vertebral artery type, sympathetic nerve type and mixed type. In mild cases, pain and numbness in the head, neck, shoulder and arm, and in severe cases, limb paralysis, dizziness, tinnitus, blurred vision, difficulty swallowing and hoarseness may occur. For patients with cervical spondylosis who do not meet the indications for surgery, physiotherapy is an effective treatment method. Physiotherapy refers to the use of artificial or natural physical factors on the human body to produce a favorable response for the purpose of preventing and treating disease. The key lies in controlling degeneration, correcting the abnormal structural disorder of the cervical spine, restoring the balance of normal cervical intervertebral forces, improving blood circulation, accelerating metabolism and promoting the repair of lesions, as well as reducing inflammation and pain, relieving the symptoms of nerve compression and stimulation, relieving the spasm of the muscles around the cervical spine and improving the function of small joints. Methods commonly used in the treatment of cervical spondylosis include electrotherapy, paraffin therapy, ultrasonic therapy, thermotherapy and magnetotherapy. 1.Medium-frequency current can relieve pain, promote local blood circulation, improve the hypoxic state of the focal area, exercise muscle function, reduce edema and tension of nerve fibers between tissues, and also have the effect of loosening adhesions, so that the pathological pain-causing medium can be cleared early. 2.Paraffin wax therapy mainly plays the role of warmth and mechanical compression, this therapy has a strong thermal effect on the tissue, lasting time, and the depth of action can reach 1cm, which is more effective for nerve root type cervical spondylosis. 3, ultra-short wave is the use of its high-frequency electric field on the human body, so that the affected molecules and ions in parallel position vibration, mutual friction generated thermal effect, this thermal effect can make the affected area vasodilatation, promote blood circulation, improve tissue nutrition and metabolism, and can make the reticuloendothelial system function enhanced, cell phagocytosis strengthen, and can reduce local inflammatory exudation, conducive to inflammation absorption, dissipation, so as to play a better Therapeutic effect. Ultrashort wave can improve local blood circulation, anti-inflammatory, anti-swelling, accelerate the removal of inflammatory media. 4.Semiconductor laser Its irradiation can regulate the function of the stellate ganglion and make the innervated arteries expand, which can improve the blood circulation of the neck and shoulder, brain, upper limb nerves and sympathetic nerves and other tissues, and restore the balance inside and outside the cervical spine. Relieves cervical muscle spasm and compression of the spinal cord, nerves and blood vessels, inhibits nociceptive transmission, blocks the vicious cycle of pain a muscle tension, and promotes the purpose of repair. 5.Thermal therapy The method of transferring heat directly into the body to achieve therapeutic effects. Commonly used heating materials include herbs, sand, salt, clay and air, etc., which are heated and applied to the surface of the lesion, thus playing the role of warming the meridians and channels, dispersing cold and relieving pain. 6, other methods: such as home simple heat compress. In the process of physical therapy, combined with Chinese medicine and massage, acupuncture, cupping, traction and other treatments, can achieve higher efficiency, clinical symptoms can be better relieved. After the treatment, patients should also do proper exercise, learn to do simple neck massage, neck gymnastics, correct bad habits, avoid working with low head for a long time, avoid cold in the neck, over fatigue and so on. In addition, regardless of the severity of the symptoms, 2 to 3 courses of physical therapy should be done every year, which is also very necessary to reduce recurrence, alleviate the symptoms and consolidate the therapeutic effect. Physiotherapy treatment of cervical spondylosis is painless, non-invasive and has no side effects. For patients for whom physiotherapy is ineffective, surgery is still recommended.
