The impact of site specificity and needle manipulation on changes to pain pressure threshold following manual acupuncture: a controlled study.

OBJECTIVES: To investigate the contribution of two principal features that underlie traditional Chinese acupuncture: site specificity and application of needle manipulation. DESIGN: Thirteen volunteers completed a randomised, dual blind (subject and assessor) repeated measures study involving five interventions. Pressure pain threshold (PPT) was measured with an algometer, before and after intervention at 10 sites (acupoints and nonacupoints) across the body. INTERVENTIONS: Deep needling, with or without manual needle rotation, applied to the acupoint Large Intestine 4 (LI4) or to a nonacupoint located on the medial side of the second metacarpal. Inactive laser to LI4 was used as a control. All interventions were administered for 21 min. MAIN OUTCOME MEASURES: Percentage change in PPT from preintervention baseline at the 10 sites during the 18 min immediately following intervention. RESULTS: Statistically significant increases from preintervention PPT means were obtained at all 10 sites following needling of LI4 with manipulation compared with one site after needling LI4 without manipulation. Needling the nonacupoint led to statistically significant increases at six sites when manipulation was present compared with none in the absence of manipulation. No significant changes in mean PPT followed inactive laser. Needling LI4 with manipulation produced mean increases that were statistically significantly greater than those for the other interventions with one exception: needling the nonacupoint with manipulation was as effective as needling LI4 with manipulation at one measurement site only. CONCLUSIONS: Both manipulation and site of needling contributed significantly to the elevation of PPT following acupuncture. Distribution of effects on PPT did not support either neural segmental or Traditional Chinese Medicine channel theories. Psychological and physiological nonspecific effects appeared to play a minimal role in changes to PPT.

Life stresses and depression in the menopause.

Research on the climacteric has largely concentrated on relationships between ovarian insufficiency, oestrogen deficiency, and climacteric symptoms. Little attention has been paid to those who have no symptoms. It is proposed, in addition to these relationships, that the life events of this period are significantly involved; and that resultant stress may contribute to oestrogen deficiency as opposed to physiologically normal postmenopausal oestrogen levels. In this preliminary study, two groups of women under conditions of relatively low stress and high stress were tested over a period of 15 mth. They were rated on the Hamilton Rating Scale for depression and anxiety and results were compared with the corresponding total urinary oestrogen output. The results, which suggest a significant relationship between stress related to depression and oestrogen levels in the menopause, are discussed and compared with differing life circumstances of the subjects.
