The incidence of neck, shoulder, lumbar and leg pain is extremely high, with preliminary estimates of more than 50 million people suffering from cervical spondylosis in China alone, and about 1 million new cervical spondylosis patients each year, and the incidence has a tendency to be younger. There are many reasons for the development of this disease, such as incorrect posture, improper labor or exercise, acute sprain, chronic strain and degenerative lesions, and so on. The treatment methods include active treatment and passive treatment. Active treatment includes practicing preventive and therapeutic exercises for neck, shoulder, back and leg pain, which requires active participation and cooperation of the participants; passive treatment such as medication, surgery, intervention, acupuncture, massage, physiotherapy, etc., which means receiving treatment after the onset of the disease. Passive treatment often takes weeks to months depending on the condition, which has a great impact on daily life and is prone to recurrence, so most people lack confidence and patience, and often seek medical treatment only when it is unbearable, thus delaying the condition and even leading to serious consequences. As a matter of fact, it is impossible to cure neck, shoulder, back and leg pain only by relying on doctors to use passive treatment methods, and most of them can only achieve temporary relief or control of symptoms, because there are too many triggers to trigger another attack of pain, and it is really impossible to prevent. In reality, the majority of people adopt a passive and blindly obedient attitude, delaying as long as they can, and then placing high hopes on doctors, eventually falling into the vicious circle of “treatment – relapse – treatment – relapse again”. In fact, the occurrence of neck, shoulder, back and leg pain is mainly due to lack of exercise, incorrect posture and incorrect exercise. Obviously, to prevent the occurrence, recurrence or aggravation of pain, the initiative is not in the hands of the doctor, but in the hands of the patient, that is, the initiative to adhere to do preventive health care and treatment exercises for neck, shoulder, waist and leg pain, active prevention, control the development, targeted exercise is the best strategy for the prevention and treatment of such diseases.

Recently in the park with friends to practice the “rice” cervical spine health exercise, just after 2 times “rice” exercise, support does not do fainting, sent to the hospital to come back to consciousness. Wang fainted because of inappropriate exercise caused by cerebral ischemia. Similarly, some therapeutic exercises are targeted, that is, only for a specific disease (pain), for other types of diseases (pain) is no therapeutic effect, or even have a negative impact, not to mention preventive health effects, such as exercise lumbar back muscle “flying swallow” action is not suitable for lumbar spine slippage caused by lumbar leg pain. In addition, even for the same disease or the same nature of pain, different individuals may have different reactions to the same exercise, and must be treated differently.
