REFLEXOLOGY
Therapeutic massage alone does not necessarily deliver stable clinical results. This type of massage therapy was originally created for healthy people, to enhance their health and improve their well being. Some of the methods of medical massage therapy are already widely (e.g., lymph drainage massage) or partially (e.g., connective tissue massage) incorporated into the arsenal of American massage therapy; some methods remain to be rediscovered or more fully explored (e.g., segment-reflex massage or periostal massage).
The medical massage practitioner occupies a special place in massage therapy. What distinguishes a massage therapist from a medical massage practitioner? First of all, medical massage demands more education and, perhaps more importantly, a commitment to permanent self-improvement. Second, the massage therapist who studies and practices for example, lymph drainage massage, cannot be considered a medical massage practitioner, but rather a lymph drainage massage practitioner. The uniqueness of medical massage therapy is in its integrative approach. In other words, the medical massage therapist has to know all major methods of medical massage therapy, and be able to blend them together to create the unique treatment protocol of the treatment for each patient. Only in such a case can stable clinical results be achieved. We do not expect surgeons to conduct an operation by knife only; they utilize a wide set of different tools. The methods of medical massage therapy are tools massage therapists use for the health benefits of their patients. With such an integrative approach, the medical massage practitioner can treat different somatic or visceral disorders using the local and reflex mechanisms of massage therapy.
The local mechanisms of massage therapy are widely known -- they play an important role in the formation of the clinical effects of massage treatment. However, in this article I will discuss the theoretical foundation of reflex mechanisms of massage therapy. These mechanisms are key elements of the major methods of medical massage therapy: segment-reflex massage; connective tissue massage; periostal massage; and neuromuscular therapy.
The human body has two major anatomo-physiological components: soma and viscera. Soma includes skeletal system and all soft tissue structures: skin, fascia, muscles, etc. Viscera includes the inner organs and systems of our body. The soma provides our locomotion, interaction with environment and also serves as a protective envelope for the viscera. Somatic and visceral structures are perfectly united together by the nervous system. The different somatic structures also interconnect with each other through the nervous system. This interconnection can be seen between different visceral structures or systems of the body. These interconnections are possible because of several principal reflexes:
Viscero-somatic reflex: This reflex establishes the connection between the inner organ, a particular area of the skin and connective tissue structures (e.g., fascia, aponeurosis). The best known example of viscero-somatic reflexes is Head's zones. These zones were mapped by English scientist H. Head in 1893. They represent particular areas of local abnormalities in the skin, formed as a result of different visceral abnormalities. For example, the patient with hepatic disorders frequently feels pain and different sensory abnormalities (e.g. numbness, tingling) in the skin on the right side of the thoracic cage and the right shoulder.
Viscero-motor reflex: This reflex was originally described by J. McKenzie in 1923. The viscero-motor reflex establishes a connection between the affected inner organ and a particular muscle or muscular group. As a result of a chronic somatic or visceral disorder, hypertonic abnormalities, in the form of hypertonus, trigger point or myogelosis, are formed in the skeletal muscles, innervated by the same segment of the spinal cord as the originally affected inner organ.
Soma-somatic reflex: This reflex establishes cause-effect relations between the different somatic structures located along pathways of the same peripheral nerve. For example, chronic irritation of the brachial plexus by the tensed anterior scalene muscle ultimately will cause carpal tunnel syndrome.
Viscero-visceral reflex: This reflex establishes a connection between different visceral structures. For example, an increase in heart rate will automatically trigger an increase in the respiratory rate, and vice versa.
The medical massage practitioner is able to use soma-somatic, viscero-somatic and viscero-motor reflexes for the treatment of various somatic and visceral disorders. The reflex mechanism of massage therapy allows the practitioner to dramatically increase the results of the treatment of somatic abnormalities, and to participate in the treatment of visceral disorders. Soma-somatic, viscero-somatic and viscero-motor reflexes are responsible for the formation of local abnormalities in the areas of soft tissues, innervated by the same segment of the spinal cord as the original somatic or visceral disorder. These areas in the soft tissues are called reflex zones. The reflex zones do not form as soon as clinical picture of original disorder is established. In cases of somatic abnormalities, the formation of reflex zones may take an average of two-to-three weeks. In cases of visceral disorders, the reflex zones are formed after approximately three months. Thus, the reflex zones in the skin, connective tissue, skeletal muscles and periosteum are formed secondarily, as the body's response to chronic various somatic or visceral abnormalities.
The concept of reflex zones was first proposed by Prof. A. Sherbak, MD, in works published between 1910 and 1936. He developed one of the most effective methods of medical massage therapy: segment-reflex massage. The conception of reflex massage therapy continued to develop in different countries. In Austria, E. Dickle and Prof. W. Kohlrausch proposed connective tissue massage in the 1930s. In Germany, Dr. P. Vogler and Dr. H. Krauss developed the concept of periostal massage in 1950s. In 1955, Drs. O. Glezer and V.A. Dalicho reshaped segment-reflex massage by publishing maps of reflex zones in cases of different somatic and visceral disorders. In Russia, Prof. O.F. Kuznetsov developed asymmetric segment-reflex massage in 1977 for the treatment of patients with pulmonary disorders.
After World War II, reflex zones were intensively studied by American scientists (Beal, 1985). Experimental studies conducted by Prof. I. Korr in 1940s allowed scientists to more deeply understand the intimate mechanisms of reflex zone formation.
What mechanism is responsible for the formation of reflex zones in the skin, connective tissue (e.g. fascia, aponeurosis), skeletal muscles and periosteum (i.e., thin connective tissue membrane which covers bones and supports their metabolism)? Let's discuss this matter with the help of figure1.
Take as example a patient suffering from a chronic gastric ulcer. The patient complains of pain in the epigastric area, heartburn, gas, belching, etc. The symptoms worsen with stress and consumption of spicy or fatty foods. The flow of these pathological impulses (solid arrows in figure 1) travels from the peripheral receptors in the stomach, through the afferent sensory neurons, to the posterior horns of the spinal cord, where all sensory information arriving at the spinal cord is primarily processed. As soon as ascending sensory information reaches the spinal neurons in the corresponding segments of spinal cord, these neurons are stimulated. The posterior horns of the spinal cord act as a computer to analyze sensory input, then transfer it to the brain. Simultaneously, these sensory impulses from the stomach are conducted to the lower motor centers, located in the anterior horns of the spinal cord. As a result of stimulation of lower motor centers, the motor commands are sent to the area with original pathological processes in the stomach, causing changes in gastric function such as increased peristalsis, decreased gastric juice production, etc.
The stimulation of lower motor centers also produces the flow of motor impulses to the areas of the skin, connective tissue, skeletal muscles or periosteum, which are innervated by the same segments of the spinal cord as the stomach. Reflex zones start to form in these soft tissues, as a result of their permanent bombardment by motor impulses. However, these motor impulses were not produced originally by the stimulation of peripheral receptors in soft tissues. They are a radiation of sensory impulses from the stomach to somatic areas innervated by the same segment of the spinal cord as the stomach. The constant flow of unnecessary motor commands to the somatic areas causes the increased tension in these areas, and reflex zone formation.
Pathological changes in the reflex zones appear in different clinical forms. As soon as the reflex zones are formed, they start to emit their own pathological impulses through the afferent sensory neurons to the posterior horns of the spinal cord (dashed arrows in figure 1). These stimuli also activate the spinal neurons, which transfer sensory information up to the brain and stimulate the lower motor centers in the anterior horns of the spinal cord. Stimulation of the lower motor centers elicits the flow of motor stimuli back to the areas of reflex zones and, at the same time, the flow of motor stimuli to the stomach. This unnecessary flow of motor impulses to the stomach accelerates the original process of ulcer formation by increasing vasoconstriction, cellular edema, and abnormalities in the gastric secretion. Thus, a vicious circle is formed which supports further development of the chronic gastric ulcer.
Segmental-reflex massage, connective tissue massage, and periostal massage can interrupt this vicious circle - by eliminating local abnormalities in the areas of reflex zones, and by blocking a reverse flow of pathological impulses from the reflex zones to the spinal cord, brain and stomach. Essentially, this is the primary goal of medical massage therapy: to evaluate, then eliminate reflex zones.
