A new study on acupuncture—the most rigorous and detailed treatment analysis to date—shows that acupuncture can relieve migraine, arthritis, and other forms of chronic pain.
This discovery provides strong scientific support for this ancient treatment. It is estimated that about 3 million Americans receive acupuncture treatment every year. Although acupuncture has been studied for decades, most of it is small and low-quality research, which has caused such medical research into confusion. The new study is over five years old and funded by the National Institutes of Health. The analyzed early research data covers nearly 18,000 patients.
The researchers have published the results in the Archives of Internal Medicine, showing that acupuncture is better than placebo in patients with osteoarthritis, migraine, and chronic back, neck, and shoulder pain And standard care.
"For a long time, this has been a controversial topic." Andrew S. J? Victoria, chief research methodology scholar at the Memorial Sloan-Kettering Cancer Center in New York and lead author of the study Dr. Andrew J. Vickers said: "But once you answer the question correctly like us, the answer is very clear."
"We believe that there is solid evidence to support acupuncture treatment of chronic pain."
Acupuncture, the method of inserting a needle into different parts of the body to stimulate "acupuncture points", is the most common form of alternative medicine (also called non-mainstream medicine) in the United States. Many hospitals provide this treatment. Adult patients with chronic pain are the most used for this treatment, but more and more children use it. According to government estimates, about 150,000 children received acupuncture treatment in 2007.
However, although acupuncture treatment is very popular, questions about its effectiveness are common. Are those who claim that their pain is relieved just kissed the soul by the placebo effect?
Dr. Vickers and a team of scientists from all over the world-the United Kingdom, Germany, Sweden and elsewhere-have dug out answers from years of data. In the past, the commonly used meta-analysis is to average the previous research results or conclusions, but this is not rigorous enough. Dr. Vickers and his colleagues first selected 29 randomized studies on acupuncture that they considered to be of higher quality, and then contacted the authors to obtain the original data, which was then carefully examined and collected. This allows them to avoid the statistical and methodological problems previously studied, so as to get a more accurate and reliable conclusion on whether "acupuncture is useful".
In short, this arduous process took the team about 6 years. "It's really not a quick and easy task to copy almost every number in dozens of papers," Dr. Vickers said.
The meta-analysis included studies comparing acupuncture and routine care, such as over-the-counter painkillers and other standard medicines. It also includes pseudo-acupuncture comfort treatment, such as the needle is inserted very shallow, or the needle of the control group will retract into the handle.
Eventually, Dr. Vickers and his team found that at the end of treatment, about half of the patients who received real acupuncture treatment reported improvement, while about 30% of those who did not receive treatment improved.
"In the world, there are 30 to 40 researchers participating in this study, and overall it feels that this is a scale with clinically important effects." Dr. Vickers said. He added that this is especially important considering that acupuncture is “relatively non-invasive and relatively safeâ€.
Dr. Vickers said the results of the study showed that the patients receiving treatment were not only psychologically encouraged. "They not only got a comforting effect," he said, "this is not a weird healing ritual."
Dr. Andrew L. Avins, a research scientist at Kaiser Permanente who specializes in musculoskeletal pain and preventive medicine, puts traditional health care in the editor ’s note after the article. The relationship between Complementary and Alternative Medicine World is described as "ambiguous", but he writes that, at least as far as acupuncture is concerned, the new research provides "strong evidence" that "acupuncture is different than conventional treatment. Patients with chronic pain have certain benefits. "
Generally, the main parameters are determined according to the requirements of the material handling system, the conditions of the loading and unloading sites, the relevant production process and the characteristics of the materials.
â‘ conveying capacity: Conveyor capacity refers to the amount of material transported per unit of time. In the delivery of bulk material, the hourly delivery of material mass or volume calculation; in the delivery of articles into pieces, the number of hours per hour delivery.
â‘¡ conveying speed: improve the transmission speed can improve the transmission capacity. When the conveyor belt is used as a pulling member and the conveying length is large, the conveying speed is increased. However, high-speed operation of the belt conveyor should pay attention to vibration, noise and start, braking and other issues. For the chain as a tractor conveyor, conveyor speed should not be too large to prevent increased power load. At the same time the process of operation of the conveyor, conveyor speed should be determined in accordance with the production process requirements.
â‘¢ component size: conveyor component size, including conveyor belt width, strip width, hopper volume, pipe diameter and container size. The size of these components directly affect the transport capacity of the conveyor.
â‘£ conveying length and inclination: the length of the transmission line and the size of the angle of a direct impact on the total resistance of the conveyor and the required power.
