Some chiropractic therapies exaggerate the curative effect, claiming that asthma, allergic rhinitis, insomnia, gastrointestinal tract and other diseases can be cured by chiropractic. However, some foreign studies have questioned the efficacy of chiropractic therapy, arguing that there is almost no strong evidence that chiropractic therapy can treat back pain, neck pain, asthma, allergies, headaches and other problems. At present, chiropractic is only effective for neuromuscular system, such as acute neck pain (such as stiff neck), acute low back pain, sciatica, disc herniation, spondylolisthesis, acute and chronic lumbar sprain, etc. As for other medical diseases such as respiratory system, circulatory system and digestive system, more research is needed to prove the benefits of chiropractic therapy. Early treatment will also affect the effect of chiropractic. If treated within half a month, the effect will be better than that after becoming chronic pain. In addition, adjusting lifestyle and exercise can promote disease recovery. Half of the treatment effect depends on yourself, and it is by no means that you can get rid of the pain forever by relying on "Joe" bones. Dr Wang Zuoliang pointed out that the human body has the ability of self-healing. Doctors adjust the body structure by hand, only to help start the body's self-healing system. Next, patients need to adjust their bad lifestyle, posture habits, and cooperate with exercise to achieve satisfactory treatment results. Therefore, when a patient comes to see a doctor for the first time, besides diagnosis and corrective treatment, he must also teach the patient exercise. Show the patient once again when he visits, make sure that the patient is doing it correctly, and remind him repeatedly to keep exercising when he goes home. If you don't exercise and change your bad habits, that is, use chiropractic to adjust your bones and muscles, after a period of time, the structure will dislocate and the pain will come back. Western medicine orthopedics mainly treats bone, joint and muscle problems with drugs and surgery, while rehabilitation mainly focuses on physical therapy, such as cold or hot compress, infrared ray, ultrasound, traction and exercise therapy. As for chiropractic, the emphasis is on "imbalance of body structure", that is, diseases caused by dislocation of bones and joints or muscle imbalance, such as disc herniation, sciatica and spondylolisthesis. Instead of taking medicine, injections, surgery and other methods, the therapist's hands are used to adjust and correct the offset and unbalanced bones and joint muscles, so that the body can recover its mobility painlessly and maximally. As a rehabilitation doctor, Wang Zuoliang, chairman of Taiwan Province Chiropractic Association, found that traditional western medicine had limited curative effect on many spinal diseases, and taking medicine, hot compress and electrotherapy could not solve the pain caused by the imbalance of body structure. So, ten years ago, he went to the United States to study chiropractic medicine, and obtained a doctorate from the School of Spinal Neurology, Southern California Health Science University. After returning home, he corrected the dislocated bones, joints and muscles of the patient by hand. Lin, an attending physician in rehabilitation department of Fuxin Hospital, believes that chiropractic can really play a role that physical therapy in rehabilitation medicine can't do at present, such as spinal dislocation. Physical therapy spinal traction or lumbar traction can only be restored to a certain extent, and it is impossible to adjust the bone back to its normal position more finely. After rehabilitation, although the pain and discomfort are relieved, the dislocation of bones may still exist, so we must continue to exercise to avoid deterioration or recurrence.
