What is pain gate theory in electrotherapy?
What is pain gate theory in electrotherapy?
The gate control theory of pain describes how non-painful sensations can override and reduce painful sensations. A painful, nociceptive stimulus stimulates primary afferent fibers and travels to the brain via transmission cells. Increasing activity of the transmission cells results in increased perceived pain.
What are the 3 pain control theories?
The four most influential theories of pain perception include the Specificity (or Labeled Line), Intensity, Pattern, and Gate Control Theories of Pain (Fig. 1). The Specificity Theory refers to the presence of dedicated pathways for each somatosensory modality.
How does TENS work pain gate theory?
The gate control theory is also thought to be involved when using a TENS machine. The electrical current stimulates nerve fibres that carry signals relating to touch. The signals travel to the spinal cord where they temporarily block the transmission of pain sensations to the brain.
What is affect theory of pain?
Affect theory is a theory that seeks to organize affects, sometimes used interchangeably with emotions or subjectively experienced feelings, into discrete categories and to typify their physiological, social, interpersonal, and internalized manifestations.
What are the two types of pain?
Pain is most often classified by the kind of damage that causes it. The two main categories are pain caused by tissue damage, also called nociceptive pain, and pain caused by nerve damage, also called neuropathic pain. A third category is psychogenic pain, which is pain that is affected by psychological factors.
What is the function of pain receptors?
A nociceptor (“pain receptor” from Latin nocere ‘to harm or hurt’) is a sensory neuron that responds to damaging or potentially damaging stimuli by sending “possible threat” signals to the spinal cord and the brain.
What are pain theories?
The four most influential theories of pain perception include the Specificity (or Labeled Line), Intensity, Pattern, and Gate Control Theories of Pain (Fig. 1).
Why is the gate control theory important?
The gate control theory is used as a basis for promoting the use of massage and strokes such as effleurage during labour. These modalities are considered to be a distraction from the pain messages that the brain is processing.
Which method of pain control is based on the gate control theory?
The gate control theory forms the basis of TENS. In this technique, the selective stimulation of the large diameter nerve fibers carrying non-pain sensory stimuli from a specific region nullifies or reduces the effect of pain signals from the region.
Who proposed the gate control theory of pain?
The Gate Theory of Pain, published by Ronald Melzack and Patrick Wall in Science in 1965, was formulated to provide a mechanism for coding the nociceptive component of cutaneous sensory input.
