Abstract

Employment of alternative therapeutic measures is increasing in Denmark. Some of this equipment employs magnetic fields in the therapeutic strategy. This may involve interference with the function of electronic equipment. Electronic interference may, in certain situations, influence pace-maker function. In the worst cases, it may be imagined that the situation may endanger life for persons who are dependent on pace-makers. When a pace-maker is exposed to a magnetic field of a certain strength, the type of pacing is changed to a fixed frequency. Some pace-maker types carry out a built-in test programme when exposed to magnetic influence (vario- or threshold test). The magnetic influence may involve discomfort for the wearer of the pace-maker, but does not endanger life. Investigation of stationary magnetic fields from alternative medical equipment resulted in disturbance of pace-maker function in an isolated case. Pulsating magnetic fields may result in possible induction of electric current which may be wrongly interpreted by the pacemaker. The results of this may be that the pace-maker does not send out pace impulses. As protection from continuous electric noise, pace-makers have a built-in electronic safety circuit (dual-demand). When this is activated, the pace-maker will stimulate with a basic frequency. It is recommended that equipment which employs magnetic fields in treatment should be measured before being employed on pace-maker wearers.

Complementary and alternative medicine for noncancer pain.

In summary, the past several years have shown an increase in the quality of trials examining the clinical efficacy of various CAM modalities for pain conditions. There is still need to raise the quality of the studies from a scientific and methodological point of view in many areas of CAM research by randomization, appropriate sample size, blinding, and developing more sophisticated sham procedures. However, much work still has to be done to find ways to preserve the clinical authenticity of CAM treatment methods when brought into the light of a research protocol. Recent attempts have been made to find a method of maintaining the standardization and reproducibility of research protocols while allowing the kind of flexible treatment that would normally be applied in a clinical setting. Other questions that should be answered with future studies include understanding how treatment length influences outcome, if maintenance treatments are needed for chronic conditions, and cost and risk comparisons with standard pharmacological treatment. Providing this kind of detail will assist both with reproducibility as well as help us gain a better understanding about whether certain treatment paradigms are superior to others for specific clinical conditions. Finally, physicians who have an interest in pursuing CAM research should educate themselves both about the methodological issues inherent with the particular area of interest as well as about ways to maintain the authenticity of the CAM treatment protocols so that the literature is not populated with more poorly designed studies. With the emerging interest in integrative medicine, there is a growing interest in collaboration and a greater number of physicians are interested in obtaining training in CAM modalities to help bridge this gap between CAM and conventional clinicians. For example, the American Academy of Medical Acupuncturists (AAMA) has been formed to help as both an educational and research forum for physician acupuncturists and the American Holistic Medical Association provides educational exposure in a broad range of Integrative and CAM modalities. The future of medicine will likely be Integrative and the more health care providers can educate themselves about this area of medicine, the better they will be able to provide the highest quality of care to their patients.
