May 18, †Ј In order to explain why our mental states impact pain perceptions, researchers Ronald Melzack and Patrick Wall proposed what is known as gate control theory during the early s. This theory suggests that the spinal cord contains a neurological "gate" that either blocks pain signals or allows them to continue on to the zi255.comted Reading Time: 4 mins. The gate-control theory (Melzack & Wall ) states that in each dorsal horn there exists a СgateТ responsible for inhibiting or facilitating afferent impulses. The control of this СgateТ depends upon the relative activity in large-diameter (A-beta) fibres and small-diameter (A-delta and C-) fibres.
At first glance, pain may seem how to get twitter metrics be a straightforward example of cause and effect. Touching a hot pan, for instance, results in pain. Although this is generally true for acute pain, chronic pain can be much different. See Acute vs. Chronic Pain. In the case gqte chronic pain, a closer look reveals a much more complex process. For many years, theories of pain did not thfory address chronic pain and the variations in responses to painЧeven for the same person.
Much of modern medicine's understanding of the process of chronic pain stems from the Gate Control Theory, which takes into account many factors that influence chronic pain, including sensory actual physical influences including gahecognitive including thoughts and beliefs about the painand emotional including feelings about the pain.
This article reviews the Gate Control Theory of pain and how it can be helpful in treating pain. In an effort to improve scientific understanding, the Gate Control Theory of pain was advanced by psychologist Ronald Melzack and biologist Patrick Wall in In the Gate Control Theory, pain messages travel from the periphery of the body through nerve "gates" in the spinal cord and up to the brain.
The theory uses the concept of "gates" in the central nervous system to describe how some pain messages are allowed get through and reach the brain, while others are blocked. Aside from just allowing and blocking pain signals completely, these gates can also amplify or diminish a signal as it travels to the brain, as illustrated in the Gate Control Theory image on this page.

The Gate Control Theory of Pain suggests that two people may experience different levels of pain based on factors like their mood and mindset. This theory also suggests that an individual may experience different levels of pain based on these factors. The Gate Control Theory of Pain is not without its critiques, but it may be the key to reducing the amount of pain you feel while getting a COVID test, . The Gate Control Theory of Pain. The Gate Control Theory. The way in which we experience pain is very complex. All sorts of factors influence our experience, including our thoughts and feelings. For example, you will probably be aware that there are times when, even though you have pain, you are only dimly aware of it. gate theory (gate-control theory) neural impulses generated by noxious painful stimuli and transmitted to the spinal cord by small-diameter C-fibers and A-delta fibers are blocked at their synapses in the dorsal horn by the simultaneous stimulation of large-diameter myelinated A-fibers, thus inhibiting pain by preventing pain impulses from reaching higher levels of the central nervous system.
The concepts and provisions set forth in a theory are more specific and concrete than those of a conceptual model. Hence a theory is derived from a conceptual model to fully describe, explain, and predict phenomena within the domain of the model. The ethics of care is a rejection of impartial, principle-driven, dispassionate reasoning and judgment that has often dominated the models and paradigms of bioethics.
Its origins are developmental psychology, moral theory, and feminist writings. Its moral concern is with needs and corresponding responsibility as they arise within a relationship.
Moral response is individualized and is guided by the private norms of friendship, love, and care rather than by abstract rights and principles. Cohnheim's theory tumors develop from embryonic rests that do not participate in the formation of normal surrounding tissue. Commitment is to the general welfare, to common purposes, and to education of community members. Beliefs and principles, shared goals, and obligations are seen as products of the communal life.
Conventions, traditions, and social solidarity play a prominent role in this type of theory. Called also communitarianism. A major postulate is that we may not use or mistreat other people as a means to our own happiness or to that of others. Deontological theories guide action with a set of moral principles or moral rules, but it is the actions themselves and their moral properties that are fundamental.
This theory is sometimes called the Kantian theory because the work of Immanuel Kant Ч has a deep effect on its formulations. There are subsystems that are discrete units such as mother-father, sister-brother, and mother-child and there is a suprasystem the community.
The main functions of the family are considered to be support, regulation, nurturance, and socialization; specific aspects of the functions change as the subsystems interact with the suprasystem. A central theme is that women's reality is a social construction and not a biological determination.
See also feminist praxis. The gate-control theory of pain. From Linton et al. The theory sought universally applicable principles and laws that would hold true regardless of the kind of system under study, the nature of its components, or the interrelationships among its components. Since the introduction of the general systems theory, theoretical models, principles, and laws have been developed that are of great value to scientists in all fields, including those of medicine, nursing, and other health-related professions.
Principles of Martha Rogers' science of unitary human beings are synthesized with major tenets and concepts from existential phenomenological thought to create a conceptual system and theory.
Major areas of focus, rooted in the human sciences, describe the unitary human being interrelating with the universe in co-creating health. Essential concepts include the human-universe-health interrelationship, the co-creating of health, and the freely choosing of meaning in becoming. Humans are unitary beings mutually co-creating rhythmical patterns of relating in open interchange with the universe.
The human being is a unity of the subject-world relationship, participating with the world in co-creation of self. Health, in this theory, is a continuously changing process that humans participate in co-creating.
Health is human becoming. It is not the opposite of disease, nor is it a state that exists. Disease is viewed as a pattern of the human being's interrelationship with the world. Nursing is both science and art. The science is nursing's abstract body of knowledge lived through the art in service to people. Three principles of this theory comprise the abstract knowledge base used to guide nursing research and practice.
The principles of structuring meaning multidimensionally, co-creating rhythmical patterns of relating, and co-transcending with the possibles provide the underpinnings for practice and research. There is a particular nursing practice methodology, the only one that evolves directly from a nursing theory.
Parse's practice methodology specifies that the nurse be truly present with the person and family illuminating meaning, synchronizing rhythms, and mobilizing transcendence. Persons choose their own patterns of health, reflective of their values. The nurse is there with the person and family as they uncover meanings and make decisions about their life situations.
True presence is an unconditional love grounded in the belief that individuals know the way. Parse has also constructed a research methodology congruent with her theory and unique to nursing. Her research methodology offers the researcher the opportunity to study universal lived experiences from the perspective of the people living the experiences. The purpose of her basic research method is to uncover the meaning of lived experiences to enhance the knowledge base of nursing.
Parse has contributed to nursing science a theory with congruent practice and research methodologies. The primary concepts of the theory, transpersonal human caring and caring transactions, are multidimensional giving and receiving responses between a nurse and another person.
Transpersonal human caring implies a special kind of relationship where both the nurse and the other have a high regard for the whole person in a process of being and becoming. Caring transactions provide a coming together in a lived moment, an actual caring occasion that involves choice and action by both the nurse and another. Person is also defined as a living growing gestalt with a unique phenomenal field of subjective reality.
The environment includes an objective physical or material world and a spiritual world. Watson defines the world as including all forces in the universe as well as a person's immediate environment. Critical to this definition is the concept of transcendence of the physical world that is bound in time and space, making contact with the emotional and spiritual world by the mind and soul.
Health is more than the absence of disease. Health is unity and harmony within the mind, body, and soul and is related to the congruence between the self as perceived and the self as experienced. Nursing is defined as a human science and an activity of art, centered on persons and human health-illness experiences.
The goal of nursing is to help persons gain a higher level of harmony within the mind, body and soul. Nursing practice is founded on the human-to-human caring process and a commitment to caring as a moral ideal. The activities of nursing are guided by Watson's ten carative factors , which offer a descriptive topology of interventions. Lamarck's theory the theory that acquired characteristics may be inherited. Metchnikoff theory the theory that harmful elements in the body are attacked by phagocytes, causing inflammation; see also metchnikoff theory.
The idea of primacy of rights has been strongly disputed by, for example, utilitarians and Marxists. Individual interests often conflict with communal or institutional interests, as has been seen in efforts to reform the health care system.
A prominent rights-based theory is what is known as liberal individualism. Utilitarianism is the most prominent consequence-based theory; it accepts one and only one basic principle of ethics, the principle of utility, which asserts that we ought always to produce the maximal balance of positive value over negative consequences or the least possible negative consequence, if only undesirable results can be achieved.
