During the last five years a large number of randomised controlled clinical trials (RCTs) have been published on the efficacy of acupuncture in different conditions. In most of these studies verum is compared with sham acupuncture. In general both verum and sham have been found to be effective, and often with little reported difference in outcome. ⋯ However, this conclusion is based on the assumption that sham acupuncture is inert. Since sham acupuncture evidently is merely another form of acupuncture from the physiological perspective, the assumption that sham is sham is incorrect and conclusions based on this assumption are therefore invalid. Clinical guidelines based on such conclusions may therefore exclude suffering patients from valuable treatments.

Randomized Controlled Trial
A placebo acupuncture needle with potential for double blinding - a validation study.
The double blind, non-penetrating placebo needle is effective in masking patients who are not informed that they may receive a placebo needle. In this study, we aimed to examine whether such needles are effective in masking subjects who have been so informed. ⋯ The non-penetrating placebo needle was effective in masking fully informed subjects. When used together with the matched penetrating needle, it has potential for use in double blind (patient and practitioner blind) studies.

Controlled Clinical Trial
Intramuscular and periosteal acupuncture in patients suffering from chronic musculoskeletal pain - a controlled trial.
Periosteal acupuncture has shown promising results in clinical practice. The aim was to compare three patient groups: one with intramuscular acupuncture, one with periosteal acupuncture, and a third information control group, with respect to clinically relevant pain relief, physical functioning and intake of analgesics in patients with chronic musculoskeletal pain in the neck or low back or both. We reported the psychological changes in these patients in a previous issue of this journal. ⋯ Periosteal pecking was no more effective than standard intramuscular acupuncture, but both were more effective than information only.

Studies by individual acupuncture practitioners have given an indication that offering acupuncture in primary care may reduce the need for referral to secondary care and reduce the costs of prescriptions. It would be informative to find out whether these findings can be supported by data from other practices. The aim of this study was to test the feasibility of surveying national data on referrals and prescribing. ⋯ We have conducted the first survey of the effects of provision of acupuncture in UK general practice, using data provided by the NHS, and uncovered a wide variation in the availability of the service in different areas. We have been unable to demonstrate any consistent differences in the prescribing or referral rates that could be due to the use of acupuncture in these practices. The wide variation in the data means that if such a trend exists, a very large survey would be needed to identify it. However, we discovered inaccuracies and variations in presentation of data by the PCTs which have made the numerical input, and hence our results, unreliable. Thus the practicalities of access to data and the problems with data accuracy would preclude a nationwide survey.

In an experiment on one of the authors, we used ultrasound to visualise an acupuncture needle completely perforating the median nerve at the acupuncture point PC6. During this procedure only a slight sensation occurred, and no pain. We conclude that, in individual cases, the median nerve might be perforated without causing pain or neurological problems.
