[The effect of acupuncture in the treatment of insomnia. Clinical study of subjective and objective evaluation].

The sleep-wake cycle is the most important circadian rhythm in man and thus constitutes an excellent indicator of internal equilibrium and of health. Sleep disorders, and particularly insomnia, affect a great percentage of the population. In daily practice, an inappropriate treatment may transform a bad sleeper into an insomniac dependent on pharmaceuticals for life. It is therefore necessary to give priority to non-chemical treatments in the management of insomnia. Acupuncture, which offers a personalized treatment, is particularly indicated for reharmonizing a disturbed sleep-wake cycle. Furthermore, there is an interesting similarity between the 5000-year-old theoretical basis of Chinese medicine and the recent scientific discoveries about man's internal rhythms. Clinical and statistical studies of the effects of acupuncture on insomnia are rare and evaluate only the subjective appreciation of sleep. Objective analysis of sleep by polysomnography permits evaluation of sleep architecture and visualizes the site and depth of action of the therapeutic method. Such studies have only been conducted in relation to pharmaceutical treatments. No such study has been carried out for acupuncture. A scientific and objective evaluation of the effects of acupuncture on insomnia by polysomnography could be not only of academic but mainly of great practical interest. If the efficiency of acupuncture is thus verified, this method could be integrated and proposed along with other classical therapeutic technics.
