Case studies and small trials suggest that acupuncture may effectively treat hypertension, but no large randomized trials have been reported. The Stop Hypertension with the Acupuncture Research Program pilot trial enrolled 192 participants with untreated blood pressure (BP) in the range of 140/90 to 179/109 mm Hg. The design of the trial combined rigorous methodology and adherence to principles of traditional Chinese medicine. Participants were weaned off antihypertensives before enrollment and were then randomly assigned to 3 treatments: individualized traditional Chinese acupuncture, standardized acupuncture at preselected points, or invasive sham acupuncture. Participants received < or = 12 acupuncture treatments over 6 to 8 weeks. During the first 10 weeks after random assignment, BP was monitored every 14 days, and antihypertensives were prescribed if BP exceeded 180/110 mm Hg. The mean BP decrease from baseline to 10 weeks, the primary end point, did not differ significantly between participants randomly assigned to active (individualized and standardized) versus sham acupuncture (systolic BP: -3.56 versus -3.84 mm Hg, respectively; 95% CI for the difference: -4.0 to 4.6 mm Hg; P=0.90; diastolic BP: -4.32 versus -2.81 mm Hg, 95% CI for the difference: -3.6 to 0.6 mm Hg; P=0.16). Categorizing participants by age, race, gender, baseline BP, history of antihypertensive use, obesity, or primary traditional Chinese medicine diagnosis did not reveal any subgroups for which the benefits of active acupuncture differed significantly from sham acupuncture. Active acupuncture provided no greater benefit than invasive sham acupuncture in reducing systolic or diastolic BP.
BACKGROUND: There is a lack of understanding about the patterns and rates of CAM use among older adults owing to a lack of research on specific types of CAM. OBJECTIVES: This study examines several dimensions of self-care deemed to be associated with CAM. Unmet health care needs, self-care attitudes, and spirituality are interpreted as health belief structures underlying CAM. METHODS: Logistic regression analysis was used to examine use of three groups of practitioner-based CAM: (a) chiropractic; (b) massage, and (c) acupuncture, homeopathy and/or naturopathy use. We analyze a subsample of 4,401 older adults drawn from the 1996/1997 and 1998/1999 waves of the Canadian National Population Health Survey. RESULTS: The logistic regression analyses indicate that self-care attitude and spirituality represent important predictors of practitioner-based CAM use. The associations for unmet health care needs were not supported. The strongest factors associated with CAM use were the illness context variables, which suggest that measures of need are key factors in leading individuals to seek other forms of health care. DISCUSSION: Practitioner-based CAM use among older adults is influenced by self-care attitude and spirituality, in addition to health status, but to varying degrees depending on the type of CAM. Support of these self-care facets suggests that there is a desire on the part of consumers to exercise choice and to participate in health care decisions when considering CAM.
UNLABELLED: From an electro-physiological point of view human skin shows an inhomogeneous pattern regarding its electrical resistance: in certain areas a decreased electrical resistance can be observed. It has been postulated that these areas correspond to acupuncture points. Subsequently, devices have been developed as detectors for acupuncture points which are used for diagnosis and treatment in acupuncture. However, most of these devices are inconsistent: they show a remarkable inaccuracy in their measurements and are poorly evaluated. Further analyses have shown that the measuring pens often used are subject to various disturbances such as pressure, angle of measurement, humidity of the skin, different thickness of stratum corneum of the skin and external disturbances such as temperature and humidity in the measuring room. MATERIAL AND METHODS: We present a new device for standardized measuring of electrical skin resistance. It consists of a field of 64 electrodes (measuring array) on a surface of 60 x 60 mm(2) and a distance of 8 mm between electrodes. For a more precise spatial resolution a field of 32 electrodes on a surface of 3.5 x 3.5 mm(2) with a distance of 0.65 mm is available. A high, precise, temporal resolution of electric potentials in human skin is realized by fast scanning of the electrodes. Technical details are described. CONCLUSIONS: First analyses of collected data show that reliable and valid measurements are possible. Using this device in a controlled and blinded study design will help elucidate the issue of altered skin resistance at acupuncture points and clarify if this phenomenon is unique at acupuncture points.
