Acunpuncture needles out low back pain

Science Daily – Six months of acupuncture treatment appears to be more effective than conventional therapy in treating low back pain, according to a study in the Sept. 24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals, although the study suggests that both sham acupuncture and traditional Chinese verum acupuncture appear to be effective in treating low back pain.

Acupuncture offers long lasting relief to migraines

CM NEWS – Acupuncture has been proved to provide effective and persistent relief of migraine headaches, according to a new study in Italy.

To check the effectiveness of a true acupuncture treatment according to traditional Chinese medicine (TCM) in migraine without aura, researchers of the Department of Medico-Surgical Specialities of University of Padua in Italy compared true acunpuncture to a standard mock acupuncture protocol, an accurate mock acupuncture healing ritual, and untreated controls.

Famous toxic herb smoothes arthritis pain

CM NEWS - Triptolide, an extract of the famous toxic Chinese herb lei gong teng, has the ability to suppress inflammation and cartilage destruction in collagen-induced arthritis mice, a Beijing study reveals.

The study was completed at the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences in Beijing. Read more

Tai Chi reduces tension headache

CM NEWS - Tai Chi, an ancient form of low-impact mind-body Chinese exercise, has been proved to be effective in reducing tension headaches and improving perceptions of physical and mental health, a UCLA study finds. Tai Chi may be an exercise-based alternative to pain killers and thus help cut pain killer addiction among many of us. Read more

Placebo effect may be at play in acupuncture studies: analysis

Reuters Health – Acupuncture can bring some relief to people with knee arthritis, but the benefits may be at least partly from a placebo effect, a new research review suggests.

In an analysis of 9 clinical trials from the past 15 years, researchers found that acupuncture generally seemed to improve knee arthritis sufferers’ pain and stiffness in the short term. The patients had osteoarthritis, a degenerative joint disease associated with age, as opposed to arthritis associated with an autoimmune disorder.

However, a closer look showed that the benefits were limited to trials that compared acupuncture with doing nothing or with “usual care,” such as anti-inflammatory medication.

In trials that compared acupuncture with “sham” acupuncture, on the other hand, there was no clear evidence that the real therapy was more effective.

Sham acupuncture is accomplished by using non-penetrating needles, or inserting needles only into the superficial layer of skin, at random sites rather than the specific points used in real acupuncture. In studies that evaluated electro-acupuncture, the sham version involved phony electrodes and “mock” electrical stimulation of acupuncture points.

The point is to keep study participants from knowing whether they were receiving the real or the placebo treatment. This helps separate the specific effects of a therapy from any placebo effects — where people feel better simply because they believe they’ve been treated.

The new findings suggest that the benefits of acupuncture for knee arthritis are at least partly due to patients’ expectations, the study authors report in the Annals of Internal Medicine.

However, that doesn’t mean acupuncture is not worthwhile, according to the researchers, led by Eric Manheimer of the University of Maryland School of Medicine in Baltimore.

Research does suggest that acupuncture has a “genuine biological effect,” and there was evidence in some studies that the real therapy resulted in somewhat better short-term effects than sham acupuncture, the researchers note.

For their study, Manheimer and his colleagues combined the results of nine clinical trials conducted in Europe, the U.S. and Thailand. The trials included a total of more than 3,500 subjects.

Each trial included a patient group that received acupuncture for knee arthritis, as well as a “control” group. In some studies, control patients were placed on a waiting list for acupuncture, while in others they received some standard therapy that acupuncture patients did not. Control patients in other studies received sham acupuncture.

In general, the Manheimer’s team found, only studies that pitted acupuncture against doing nothing, or against standard care, showed clear benefits. The results of the sham-controlled trials were too mixed to show any benefits, according to the researchers.

The investigators do not, however, dismiss the potential benefits of acupuncture for knee arthritis. Indeed, they note, a possible explanation for the mixed results is that sham acupuncture had some actual biological effects.

Given the overall safety of acupuncture, the researchers conclude, patients can still consider it as one option in a “multidisciplinary approach” to treating knee arthritis.

Acupuncture-like stimulation relieves chronic tension headache

CM NEWS – A group of scientists at the University of Aarhus of Denmark recently published a report of a randomized, double-blinded, placebo-controlled trial on the effect of acupuncture-like electrical stimulation on chronic tension-type headache. They have demonstrated that such practice might provide a safe and potentially analgesic-sparing therapy to tension headache.

What is tension-type headache? A tension headache is the most common headache, and yet it’s not well understood. A tension headache generally produces a diffuse, usually mild to moderate pain over your head. Many people liken the feeling to having a tight band around their head.

A tension headache may also cause pain in the back of your neck at the base of your skull. A tension headache can last from 30 minutes to an entire week. You may experience these headaches occasionally, or nearly all the time. If your headaches occur 15 or more days a month for several months, they’re considered chronic. Unfortunately, chronic tension headaches sometimes persist for years.

A tension headache may cause you to experience a dull, achy pain or sensation of tightness in your forehead or at the sides and back of your head. In its most extensive form, the pain feels like a hooded cape that drapes down over the shoulders. The headache is usually described as mild to moderately intense. The severity of the pain varies from one person to another, and from one headache to another in the same person. Many people report that the pain starts first thing in the morning or late in the day when work stress or conflict at home is anticipated.

In the study, 36 patients (18 men, 18 women) with chronic tension-type headache in accordance with the criteria of International headache Society were investigated. The patients were randomly assigned into 2 groups: a treatment group and a placebo group. Pain duration, pain intensity on a 0 to 10 cm visual analog scale, number of headache attacks, and use of medication were recorded in a diary for 2 weeks before treatment (baseline), early stage of treatment (Treat-1; 2 wk), late stage of treatment (Treat-2; 4 wk), and after the end of treatment (Post-1, Post-2, Post-3 corresponding to 2, 4, and 6-wk follow-up).

The patients also provided an overall evaluation of the treatment effect at each stage. Patients were taught how to use either an acupuncture-like electrical stimulator or a sham stimulator (identical but incapable of delivering an electric current) and then instructed to use the device at home.

Six acupoints, bilateral EX-HN5, GB 20, LI 4, were selected to be stimulated 3 minutes for each point, twice a day.

The results showed that the pain duration was shortened at Treat-1 and pain intensity was decreased at Treat-1 and Treat-2 compared with baseline. The overall evaluation of the 2 treatments indicated improvements in both the treatment and the placebo groups, but with no significant difference between the groups (P>0.061).

Despite the apparent improvement in both the treatment and placebo groups, a decrease in analgesic use was only observed in the treatment group. There was also a significant positive correlation between the reported intensity of the stimulus-evoked sensation and the evaluation of the effect of either active or placebo treatments (P=0.039).

In conclusion, the researchers said that the use of acupuncture-like electrical stimulation was not associated with significant adverse effects. These results indicate that acupuncture-like electrical stimulation is a safe and potentially analgesic-sparing therapy that may be considered as an adjunctive treatment for patients with chronic tension-type headache although the clinical effect on pain seems to be marginal in the present set-up.
