Introduction
PNE is a method that instructs patients to reconsider their perceptions of pain. Pain neuroscience education uses various metaphors and stories to help patients reframe their understanding of pain. Since patients are typically interested in learning about the best ways to treat their pain, clinicians may frequently need to understand their capacity to comprehend the complexity of pain.
PNE attempts to lower fear connected to movement, increase pain thresholds while exercising, and reduce pain-related brain activity. In actual practice, this frequently entails the employment of instructive analogs of pain, re-education of patient misunderstandings regarding the cause of the disease, and direction for attainable adjustments to lifestyle and exercise.
The training of persons with pain more about the neurology of their pain has been found to elicit amazing immediate and long-term effects based on an extensive amount of high-quality studies. PNE has been demonstrated to improve patient knowledge of pain systems, decrease healthcare utilization, and reduce pain, disability, and psychological issues.
What Is Pain?
Mosely (2007) redefines how we think about pain.
-
Pain does not indicate the health of the tissues.
-
There are numerous elements from the physical, psychological, and social domains that influence pain.
-
As pain worsens, the connection between tissue health and pain becomes less predictable.
-
Pain can be considered the conscious counterpart of the subliminal assumption that tissue is in danger.
What Is Pain Neuroscience Education?
PNE comprises in-depth patient education sessions on the neurobiology, neurophysiology, and nervous system's role in pain processing. Since 2002, physiotherapists have employed this educational strategy therapeutically in several nations (including the UK, the US, and Australia), and it is very different from conventional educational approaches like back school and biomechanical models.
Chronic pain in PNE is thought to be produced by brain plasticity, which leads to hyper-excitability of the central nervous system, a condition known as central sensitization.
Central sensitization is described as an increase in the reactivity of nociceptors in the central nervous system when subjected to normal or sub-threshold afferent input, which results in
-
Excessive sensitivity to stimuli.
-
Response to non-noxious stimuli.
-
Pain response elicited by stimuli outside the damaged location, resulting in an enlarged receptive field.
What Does PNE Invlove?
First and foremost, PNE simplifies the difficult process of describing the nerves and brain into a form understandable to everyone, regardless of the target audience's age, educational level, or ethnicity.
Simplified scientific terminology combined with extra information-presentation techniques, such as using:
-
Basic images.
-
Booklets.
-
Metaphors.
-
Drawings.
-
Workbook containing reading and question-and-answer exercises.
-
Pain questionnaires based on neurophysiology.
PNE is delivered in a variety of ways, but it normally involves 4 hours of instruction given to a group or an individual, either in a single session or over several.
What Is the Impact of PNE on Low Back Pain?
Studies evaluating the impact of PNE as a standalone intervention were included in the systematic review of evidence that looked at the impact of PNE on patients' musculoskeletal and LBP conditions. PNE's influence was discussed in two investigations by Wood and Hendrick and five studies by Louw et al. The findings revealed that no study could considerably reduce pain, and there was either no evidence at all or just weak to moderate evidence that impairment would improve throughout the stated periods.
Even though PNE's effectiveness on physical characteristics is unsuitable as a stand-alone intervention, its impact on psychosocial components provides encouraging data to promote its usage. There is evidence that PNE can enhance other factors, such kinesiophobia and attitudes toward sickness, that can facilitate function. Even if the data is limited, it cannot fully support each unique application of PNE; consequently, more research is required.
What Is the Impact of PNE on Physiotherapy?
To use a multi-modal strategy in treating chronic back pain, clinicians frequently combine the administration of PNE with standard physiotherapy care (manual therapy/exercise prescription). PNE, in conjunction with physiotherapy therapies to temporarily reduce pain, is backed by strong evidence. In the short term, there was low to moderate evidence for pain, according to a systematic review and meta-analysis of the research on PNE and physiotherapy for treating persistent low back pain. Further studies also highlight its modest improvements in impairment. No one sort of physiotherapy intervention is highlighted in the data as being better than another.
Emerging research, however, has shown favorable evidence to support PNE in conjunction with motor control training (MCT), since it is believed to provide more effective effects in reducing pain and impairment compared to current best-evidence physiotherapy care. Although this conclusion was limited to women due to the group investigated, MCT has also demonstrated superior effects on core stability training.
Because there is little evidence, it is difficult to tell which type of intervention to pair with PNE, and this necessitates greater study to identify distinct differences between the interventions. Clearer conclusions may be established with the use of updated systematic evidence.
The impact of PNE and physical therapy on patients' psychological well-being suggested prospective improvements to kinesiophobia and catastrophization. Still, these gains were insignificant and failed to exhibit clinically significant alterations.
Conclusion
In the PNE procedure to aid patients in their rehabilitation following lumbar radiculopathy surgery, no particular metaphor or tale proved superior to other metaphors. To better understand their pain experience, patients may find it helpful to blend several pain metaphors into a single story.
Therefore, it may not matter which particular metaphors the physician uses as long as they are all connected to a core knowledge of why the patient still feels. It can be crucial that there are no conflicting messages from the healthcare professional and that the message is congruent when the patient triangulates information from the several stories and metaphors that are a component of the PNE process.
