When considering a medical intervention like acupuncture, which originated centuries ago in non-Western culture (China), it is relatively easy to make it look faintly absurd by contrasting its conceptual vocabulary with that of modern day medical science. Undoubtedly, many practices of bygone days were, we now know, exceedingly dangerous and rooted in magical or religious thinking (illness as divine retribution). No one today would attempt to heal a wound by applying a poultice of dung, for example. But some practices, like acupuncture, have withstood the test of time and are still with us. Is its survival merely a function of the wishful thinking of individuals with an irrational mistrust of mainstream medicine, or might there be something more to it?
Defining Acupuncture To begin with vocabularies: the ancient Chinese clearly did not have our 21st century knowledge of physiology, anatomy and biochemistry. The words they used were rather different than our modern day references to cell membranes, endoplasmic reticula and neurotransmitters. They believed that the body was invested with a constantly flowing life energy, ‘chi’ (or ‘qi’); should this energy be blocked in its flow, or become unbalanced in its distribution, illness and pain would result. Chinese acupuncturists sought to unblock the chi pathways (‘meridians’), restore energic balance and return the patient to health. While these terms may seem strange or even a little quaint to modern day medicine, they are not entirely different from the concepts of a much more modern figure – Sigmund Freud. Freud began life as a neurophysiologist then proceeded to develop psychoanalysis, in which he used the analogy of a life energy he called ‘libido.’ In his psychological work, Freud concluded that individuals became ill or profoundly unhappy when their libido was obstructed, unbalanced, or simply waning.
Whether one chooses to believe in the conceptual basis of ancient acupuncture or not, there is some compelling scientific evidence that it can indeed have discernibly positive effects with some patients and with certain medical disorders. Furthermore, as acupuncture is being increasingly practiced in the West, chiefly as a form of complementary medicine, painstaking efforts have been made by its practitioners to develop concepts and causal explanations which are compatible with advanced knowledge of physiology, anatomy and biochemistry.
Acupuncture, for example, is now known to produce analgesic effects by activating the body’s endogenous opioid peptide system, releasing natural, pain-relieving opiates (endorphins) into the blood. One method of pain-relief acupuncture uses high-intensity, low frequency electrical stimulation of acupuncture needles to produce a slow-onset but cumulative effect which becomes generalized throughout the body as endorphins are progressively released. The other method produces more localized and rapid effects through activating the monoamine-dependent system using high-frequency, low-intensity electrical stimulation of acupuncture needles.
This medically informed or ‘hybrid’ acupuncture has devised a plausible model of the therapeutic actions of the needles. They are believed to activate nerve impulse transmission in the neuropeptide and neurohumoral systems and also produce biochemical and cellular changes in the cardiovascular system. In addition, the needles are believed to influence the flow of ions in the lymphatic system, a model which parallels the more ancient notion of chi energy flowing through meridians.
The Uses of AcupunctureThe treatment continues to employ the insertion of fine, sterile needles into the body in highly specified areas. The needles are then activated manually, thermally or through electrical stimulation, and left in situ for between five and 20 minutes. Alongside their scientific medical knowledge, hybrid acupuncturists tend to retain the concept of unbalanced or obstructed energy flow and have developed a sophisticated model of how specific organs may influence particular conditions. For example, in addition to the physiological functions of, say, the kidneys which have been established by scientific Western medicine, acupuncturists hold that these organs also supervise a range of other physiological processes and anatomical structures. These include scalp hair, hearing, joints, bone and marrow, as well as psychological characteristics such as will and motivation.
This is where more orthodox medical scientists may express a degree of skepticism, of course, yet, nonetheless, physicians are increasingly turning to acupuncture as a complementary approach in the management and treatment of a number of conditions. In the United States, it is increasingly accepted as an effective means of helping to alleviate pain in numerous musculoskeletal conditions. Acute conditions such as soft tissue bruising, nerve entrapments, sprains, strains and muscle spasms are sometimes referred to acupuncturists for the initial pain relief therapy, whereas more chronic conditions tend to require combined pain relief methods, with acupuncture being but one component. These conditions include repetitive strain disorders such as carpal tunnel syndrome and tennis elbow, but also more severe conditions such as osteoarthritis – one study showed that acupuncture significantly diminished knee-pain and increased joint mobility in patients with osteoarthritic knees.
Other chronic musculoskeletal disorders treated with acupuncture as an adjunctive therapy (i.e., in addition to pharmacological treatment or more invasive medical procedures) include the widespread pain and tenderness in muscle and soft tissue known as fibromyalgia, and some forms of lower back pain such as degenerative disc disease. However, it has also been used effectively to treat asthma, reduce dental pain, menstrual cramps and labor pain, as well as alleviate tension headaches and migraines.
Moreover, its credibility is enhanced by the willingness of its more sophisticated practitioners to concede that it is no panacea or miracle treatment. There is little evidence that it has any appreciable effect, for example, as a primary therapy in the treatment of cerebrovascular accidents, although it may assist as an adjunctive therapy in stroke rehabilitation. Similarly, it is relatively ineffective as a sole therapy in the treatment of spinal injuries or chronic immune-mediated or inflammatory disorders such as ulcerative colitis and is regarded by most of its practitioners as an inappropriate treatment method for conditions such as HIV or chronic fatigue states, even though it may help enliven and energize very seriously ill patients.
While hybrid acupuncture at least attempts to sustain a dialogue between Western and Eastern modes of thought in the field of health and medicine, ultimately it may be impossible to create a completely unified language or conceptual model. The dialogue is, however, yielding interesting and positive results as well as fostering a greater degree of mutual respect for the two perspectives.
