Myofascial pain syndromes have a significant share in the practice of a doctor engaged in rehabilitation medicine: the proportion of patients suffering from this pathology reaches 40%. At the same time, the causes of pain syndromes cannot always be established due to a number of objective difficulties, for example, in view of uncontrolled self-medication with systemic analgesics, nonsteroidal and steroid anti-inflammatory drugs, as well as uncontrolled and unskilled use of physiotherapy procedures, the availability of which has increased dramatically recently due to the commercialization of restorative medicine. The above has determined the relevance of our original clinical study, the purpose of which was to determine the possibility of a therapeutic and diagnostic algorithm using the method of functional (manual) muscle testing when choosing essential oils for aromatherapy in order to restore the regulation of muscle contraction and eliminate negative emotions based on the results of examination of patients with various myofascial pain syndromes and lesions of the autonomic nervous system that occur against the background of psycho-emotional disorders. As a result of our research, we have identified a number of reasons for the development of objective symptoms of myofascial pain syndromes in patients, the leading of which, in our opinion, are primary disorders in the emotional sphere, leading to distress. At the same time, multicomponent personalized aromatherapy can significantly eliminate excessive emotional reaction in the patient. Thus, the method of functional (manual) muscle testing makes it possible to quickly identify a violation of muscle contraction in a particular patient with myofascial pain syndrome and establish its cause, and personalized multicomponent aromatherapy is an effective method of physiotherapy for it. The original material presented by the team of authors is supported by a set of necessary citations and valid statistical data with correct references to primary sources, the regulatory framework and representative literature on the topic of this clinical scientific study.
